Natural Gas or Propane: Which is Right for You?
One of the key decisions pool owners face when purchasing a gas heater is choosing between natural gas and propane. Both fuels have distinct advantages:
Natural Gas: If your property already has a natural gas line, this is often the most convenient and cost-effective option. Natural gas heaters typically have lower operating costs in regions where utility gas prices are stable.
Propane: For rural or off-grid homeowners without access to natural gas, propane provides flexibility. While propane can be more expensive per BTU, propane heaters deliver the same heating speed and performance as their natural gas counterparts.
Both fuel types are capable of heating water quickly, often raising pool temperatures by several degrees in just hours. For those who want on-demand heating โ say, warming the spa before an evening soak โ gas heaters remain the fastest solution available.
Top Pool Heat Pumps of 2025

Pool Heaters vs. Heat Pumps
So, which heating technology is better โ gas heaters or heat pumps? The answer depends on your climate, usage habits, and budget.

Gas Heaters (Natural Gas or Propane)
๐ฅ Best for: Cold climates, large pools, and spa owners who want rapid on-demand heating.
โ
Pros: Heats water quickly, unaffected by outdoor temperature.
โ Cons: Higher ongoing fuel costs, less energy efficient.
Heat Pumps
๐ฅ Best for: Warm and mild climates where efficiency matters more than speed.
โ
Pros: Extremely energy efficient, lower operating costs, eco-friendly.
โ Cons: Slower heat-up times; performance drops in colder air temperatures.
Many homeowners choose gas heaters for spas and heat pumps for pools, or even install both for maximum flexibility.
Choosing the Best Product for Your Pool
When selecting the right pool heating solution, consider:
- Pool Size & Volume โ Larger pools may require higher BTU gas heaters or large-capacity heat pumps.
- Climate & Location โ Heat pumps thrive in warmer regions; gas heaters dominate in cooler climates.
- Usage Habits โ If you want to swim year-round or heat a spa quickly, gas heaters may be worth the fuel cost. For those looking to maintain a comfortable temperature consistently, a heat pump is usually more cost-effective.
- Budget โ Gas heaters typically cost less upfront but more to operate. Heat pumps cost more initially but offer significant long-term savings.
- Automation & Integration โ Most leading models are automation-ready, making it easier than ever to manage heating from your smartphone or pool system controller.

Pricing a Pool Heater or Heat Pump
When it comes to cost, the conversation starts with equipment price. Gas heaters generally enter the market at a lower price point. A compact 175,000โ200,000 BTU model often sells for around $1,800 to $2,500. Mid-range heaters in the 250,000โ300,000 BTU class usually run between $2,500 and $3,500, while the biggest 350,000โ400,000 BTU units for large pools can exceed $5,000. Heat pumps begin higher. Most standard residential models range from $2,800 to $4,000, and larger 120,000โ140,000 BTU or inverter-driven units with heat-and-chill features can climb to $6,000 or even $7,500.
The real difference shows up in monthly energy bills. A gas heater running on natural gas typically costs $200 to $400 a month to operate, depending on pool size and how frequently itโs used. Propane can push those costs even higher. Electricity costs for a heat pump are much lower, usually falling between $50 and $150 per month in most regions. That efficiency makes heat pumps especially attractive for homeowners in warmer climates where the units can draw plenty of heat from the surrounding air.
Over the lifetime of the equipment, gas heaters tend to last five to ten years, which means most owners will spend between $12,000 and $18,000 over a decade when fuel and equipment are combined. Heat pumps last longerโtypically ten to fifteen yearsโand although they cost more to install, the lower operating expense brings total ten-year ownership costs closer to $7,000 to $10,000.
Quick Comparison
| Category | Gas Heater | Heat Pump |
|---|---|---|
| Upfront Price | Lower ($1,800โ$5,000) | Higher ($3,000โ$7,500) |
| Operating Cost | Higher ($200โ$400+/mo) | Lower ($50โ$150/mo) |
| Speed | Fast heating | Slower heating |
| Lifespan | 5โ10 years | 10โ15 years |
| Best For | Cold climates, spas, on-demand heating | Warm/mild climates, steady seasonal use |

iGarden K Series Review: What We Learned After Months in a Customerโs Pool

Robotic pool cleaners can look impressive under controlled conditions. The more meaningful test isnโt how a cleaner performs in a demonstration environment, but how it handles real-world conditions in an actual swimming pool over time.
Leaves, dirt, pet hair, changing weather, irregular pool geometry and everyday use can expose things that simply donโt show up during a short product demonstration.
That was the idea behind Pool Magazineโs recent evaluation of the iGarden K Series robotic pool cleaner.
Rather than conduct a short-term test, we placed the K Series with pool professional Kelli Clancy, owner of Legacy Pool and Spa in Sacramento, who installed the unit in one of her customerโs pools. The homeowner used the cleaner over an extended period, while Clancy monitored its performance and gathered feedback about what worked well and where the cleaner had limitations.
The result was a practical assessment of a cordless robotic cleaner that Clancy believes could make a compelling option for homeowners buying their first robot.

A Real Backyard Instead of a Test Tank
Clancy deliberately selected a pool that would give the K Series plenty to contend with.
โI chose this particular pool for a variety of reasons,โ Clancy explained. โOne, I knew the customer would give me honest feedback. I knew she would try and get everything she wanted out of the cleaner and give an honest review.โ
The surrounding landscape also created a good mixture of debris.
โThey had small leaves, big leaves, pine trees,โ Clancy said. โSo it was a variety of debris I wanted to be able to know if it could pick up.โ
As luck would have it, an unrelated issue had also temporarily taken the poolโs circulation system offline, leaving the water somewhat dirtier than usual when the K Series arrived. That provided another opportunity to see how the cleaner handled real debris rather than a carefully prepared demonstration.
The pool itself presented an additional challenge. It was an older freeform gunite pool with curves, varying radiuses and features that would test the cleanerโs ability to navigate something considerably more complicated than a rectangular test pool.
For Clancy, that distinction matters when evaluating robotic cleaners.
โItโs not as authentic as putting it into somebodyโs pool in an everyday yard where you have, you know, squirrels, and dogs, and wind, and rain, and all these varieties of things going on,โ she said of controlled product demonstrations.

Strong First Impressions
Out of the box, the K Series made a favorable impression.
โI thought it had a very sleek look,โ Clancy said. โIt has a great look to it, you know, very modern. It wasnโt too bulky, which I did like about it.โ
More important than aesthetics was the filtration system. The cleaner includes a fine-mesh filter that fits onto the debris canister, allowing it to capture smaller material in addition to larger debris.
โI really liked that it came with that so it can catch that fine debris such as dog hair or dirt,โ Clancy said.
The cordless design was another immediate positive for the homeowner. She had previously owned another robotic cleaner that required placement on a charging base. The K Series offered a simpler arrangement.
โShe liked on this one you could just plug it anywhere,โ Clancy said. โYou didnโt have to put it on a base, and it charged within three hours. She really liked that aspect of it.โ
For a homeowner who wants a cleaner without adding another permanent charging station around the pool area, that simplicity can be an attractive feature.

Cleaning the Floor, Walls and Waterline
The K Series provides operating modes for floor cleaning as well as floor-and-wall cleaning. Once operating in the latter mode, Clancy found that the robot was capable of climbing the pool walls all the way to the waterline.
โIt did go up the walls and did a good job at cleaning them,โ she said. โSo I really liked that about it.โ
That capability stood out to the homeowner because previous cleaners she had owned did not provide the same wall-cleaning performance.
โThat was a feature she really enjoyed,โ Clancy said.
The robot also surprised Clancy by making its way onto the poolโs tanning ledge.
โIt went up onto the tanning ledge. And that was surprising to me,โ she said.
What impressed her most, however, was how quickly the K Series could make a noticeable difference.
โMe personally, watching it, I thought the cleaner did really well. I found that it cleaned the pool fairly quickly, which was really nice,โ Clancy said. โSo then if you have a party, you can just toss that in there and know within an hour that poolโs gonna be ready to go.โ
Its ability to reach the waterline added another layer of cleaning.
โIt climbs all the way up to clean the tile line, so that was really nice, too, if you havenโt brushed your tile in a while and have some leaves along there this will do a great job with that,โ she added.

Handling Real Backyard Debris
Ultimately, a pool cleaner needs to pick things up, and Clancy came away impressed with the K Seriesโ ability to collect larger debris.
She specifically pointed to the tracks and intake design at the front of the cleaner.
โI think they got right with the tracks on the front where itโs collecting the debris,โ Clancy said. โThose were very grippy, and when I watch it go over a pile of leaves, it was able to pull it in easily.โ
Combined with the fine-mesh filtration, that gave the cleaner the ability to contend with the mixture commonly found in residential pools, including dirt, dog hair, leaves and pine needles.
Clancy sees that versatility as increasingly important as backyard landscaping becomes more elaborate and homeowners expect robotic cleaners to handle more than one specific type of debris.
Where Pool Geometry Matters
No robotic cleaner is necessarily going to perform identically in every swimming pool, and the K Series was no exception.
The test pool presented a particularly challenging combination of freeform curves and relatively narrow steps. The K Series has a fairly wide wheelbase, and Clancy observed that it could climb some steps but had difficulty stabilizing on others.
Importantly, she believed some of that behavior was specific to the dimensions of this particular pool.
โThis particular issue may not be an issue in other pools, depending on the width of the steps,โ Clancy explained. The steps in the test pool were approximately 10 inches wide, and she felt even slightly wider steps could have made it considerably easier for the robot to stabilize.
The irregular curves of the older freeform pool also occasionally presented navigation challenges. Based on what she observed, Clancy believes the K Series is likely to perform at its best in more geometrically shaped pools.
That doesn’t negate its performance in the test pool. The cleaner still climbed walls, reached the tile line, accessed the tanning ledge and collected a wide range of debris. It does, however, underscore something consumers should consider with any robotic cleaner: pool shape and feature dimensions can influence performance.
An Area With Room for Improvement
The primary area Clancy would like to see improved is app connectivity when the cleaner is submerged.
โThe app needs a little improvement,โ she said, noting that communication with the unit became less reliable once it was underwater.
For routine operation, however, Clancy found the cleaner itself straightforward to set up and use. When asked what might distinguish the K Series for someone comparing similarly priced robotic cleaners, she immediately pointed to that simplicity.
โEasy to program,โ Clancy said. โIt was pretty easy to program. I think that thing took maybe five minutes tops to program completely.โ
The homeowner also appreciated a decidedly low-tech feature: the retrieval hook.
โThat was one thing the homeowner did love was the hook that came with the cleaner actually worked,โ Clancy said. Compared with another robot the homeowner had used, retrieving the K Series from the pool was considerably easier.
It may seem like a small consideration, but usability extends beyond how well a robot cleans. Charging it, programming it, removing it from the water and emptying the debris can determine whether a homeowner actually enjoys owning the product.

A Strong Entry Point Into Robotic Cleaning
With robotic cleaners now available across a wide range of prices and feature sets, one of the biggest questions is where a particular product fits.
For Clancy, the K Series occupies an appealing position for consumers who want to move into robotic cleaning without immediately jumping to the highest-priced equipment on the market.
โI would say itโs gonna be that middle ground customer, someone whoโs looking for something thatโs not the cheapest but not the most expensive,โ she said. โMaybe more of your entry level robotic owner.โ
Ease of use strengthens that argument.
โOverall, it seemed very easy to use for anybody, even somebody who doesnโt have ever used a robot,โ Clancy said.
That may ultimately be one of the K Seriesโ strongest selling points. Robotic cleaners have become increasingly sophisticated, but sophistication isn’t necessarily what every homeowner wants. For someone purchasing their first cordless robotic cleaner, being able to charge it, program it quickly, drop it into the pool and retrieve a canister full of debris without a steep learning curve has considerable value.
Clancy’s final assessment carries additional weight because she doesn’t automatically endorse every cleaner she encounters.
โI could see this being a cleaner that I would recommend to people,โ she said. โAnd I donโt recommend just any cleaner. I want something that actually works because, you know, itโs not a small price tag to get a robotic.โ
After months in an actual customer’s backyard, the iGarden K Series showed itself to be an approachable cordless robotic cleaner with good debris pickup, wall and waterline cleaning, straightforward programming, convenient charging and thoughtful everyday usability.
There are areas where future generations could improve, particularly app connectivity and navigation around certain freeform curves or narrow features. Those considerations are worth understanding when matching any cleaner to a particular pool.
For homeowners looking to make the jump from traditional pool cleaning equipment to their first robotic cleaner, however, the K Series offers many of the capabilities that make robots attractive in the first place without making the experience unnecessarily complicated.
Should You Buy the iGarden K Series?
Yes.
The iGarden K Series makes the most sense for someone who wants to get into robotic pool cleaning without paying a premium for features they may not need. Itโs a practical entry point into the category and, based on our real-world testing, capable enough to justify the investment.
That doesnโt mean itโs the perfect cleaner for every pool. More complex pool shapes and features deserve some consideration, and buyers expecting flawless app control may want to temper their expectations. But those shortcomings werenโt significant enough to change our overall opinion of the product.
What matters is whether the K Series delivers enough cleaning capability, convenience and usability to make owning one worthwhile. We think it does.
If youโve been considering making the jump to a cordless robotic cleaner and want a capable unit without immediately moving into the upper end of the category, the iGarden K Series earns our recommendation.
And for an entry-level robotic cleaner, getting those fundamentals right matters most.

WYBOT Pushes Robotic Pool Cleaning Toward Greater Autonomy

Robotic pool cleaners have become one of the fastest-moving equipment categories in the pool industry. Cordless operation, smarter navigation, app connectivity and increasingly autonomous cleaning have changed what pool owners expect from these machinesโand created an increasingly crowded field of manufacturers looking for their attention.
WYBOT may appear to be one of the newer names competing for a piece of that market. The company behind the brand, however, is anything but new to robotic pool cleaning.
โWe’ve actually been around for 20-plus years manufacturing robotic pool cleaners,โ said Nathaniel Michaelis, General Manager and Vice President of the Americas for WYBOT. โAbout three years ago, we were innovating on behalf of other brands and we said, โHey, why aren’t we doing this for ourselves?โโ
That decision marked an important change in strategy. Rather than continuing to put its newest engineering behind other brands, the company began concentrating those innovations under WYBOT. Michaelis said the company continues to manufacture for some well-known brands in the pool industry, but its latest technology is now being developed for its own product lineup.
That history provides some useful context in a category where new robotic cleaner brands seem to appear almost overnight. WYBOT is a relatively young consumer-facing brand backed by considerably older manufacturing and engineering experience.
The bigger question is how the company intends to distinguish itself in an increasingly competitive market.
Where WYBOT Achieves Differentiation
Michaelis points to what WYBOT calls โmeaningful innovationโโfeatures designed to eliminate an actual step in pool maintenance rather than simply adding another feature or gimmick.
โI think the perfect example there is our newest launch, the WYBOT S3, which is the first self-emptying robotic pool cleaner,โ Michaelis said. โSo it’ll actually go out, clean your pool, come back, dock itself in the water, and empty all the debris that it just picked up.โ
For Michaelis, that is representative of WYBOT’s larger philosophy.
โThat tells the story of who we are and how we’re differentiating ourselves,โ he said, describing an approach centered on meaningful innovation that improves the overall pool ownership experience.
That philosophy becomes easier to understand when looking at WYBOTโs two principal product families, the C Series and S Series.
While there is some crossover in technology, they occupy distinctly different positions in the lineup.

โThe C Series is our core,โ Michaelis explained. โC stands for core. And the C Series is where we try to bring the most meaningful innovation at the most accessible price points.โ
In practical terms, the C Series is designed around the everyday residential pool owner. These are self-contained, battery-powered robotic cleaners intended to provide many of the capabilities consumers increasingly expect from cordless cleaners without moving into the price and feature territory of WYBOTโs flagship models.
That includes technology such as AI Vision, which Michaelis said allows the cleaner to identify and prioritize dirtier areas of the pool rather than treating every section of the vessel exactly the same.
โWhen you take a step up into the S Series, that’s when you get into our more premium products,โ Michaelis said. โSo you’ll get longer run times and battery life, more square footage for larger pools, and then that’s where we start to introduce some of those really cool features like in-the-water charging and self-emptying.โ
Cutting the Cord Was Only the Beginning
Cordless operation itself represents an important shift in robotic pool cleaning. Traditional suction-side cleaners require hoses, while earlier generations of robotic cleaners remained tethered to power supplies. Removing those connections changes the ownership experience.
With WYBOTโs cordless technology, the process is intentionally straightforward: charge the cleaner, place it in the pool and select the appropriate cleaning mode. Depending on the model and setting, the robot can address the pool floor, walls, waterline and steps.
Once cleaning is complete, it returns to its retrieval point. WYBOT includes a hook that attaches to a standard pool pole, allowing the cleaner to be brought to the surface.
โWhat we’re trying to do with cordless technology is really simplify that experience of cleaning the pool,โ Michaelis said.
The S Series starts from that cordless foundation and asks a different question: how many of those remaining interactions can be eliminated too?
Cordless cleaners solved the cord problem, but they created another routine. The cleaner still has to be removed from the pool to recharge.
Michaelis said WYBOT heard that complaint directly from customers.
โYeah, it’s great that I don’t have a hose, which is truly something I’m looking for, but that one step further that I wish I didn’t have to take is removing the cleaner from the pool every time that it needs to be charged.โ
That feedback led to the S2 Solar and S2 Solar Vision.

Instead of requiring the owner to retrieve the cleaner and connect it to a charger after each cycle, the robots can dock themselves along the side of the pool. A solar-powered dock charges the cleaner while it remains in the water.
โThe sun charges the base. The base then charges the robot,โ Michaelis explained. โThe robot then can be set on a schedule to run Monday, Wednesday, Friday or however many days the pool owner would like it to run during the week.โ

The result is a robotic cleaner beginning to function more like permanent automated pool equipment than an accessory that must manually be deployed and retrieved.
But WYBOT kept listening, and customers identified yet another point of friction.
โOur customers said, that’s great that it’s charging in the water,โ Michaelis recalled hearing, โbut I have to take the robot out to clean the basket.โ
That became the problem targeted with the latest iteration, the S3, which incorporates the functionality of the S2 Solar Vision and now adds self-emptying capability. After completing its cleaning cycle, the robot returns to the dock and transfers collected debris into a separate poolside bin.
โAll the pool owner or the pool pro is doing is taking that tray out and emptying that tray of all the debris and putting that tray back in,โ Michaelis explained.
It’s a relatively simple action, but it represents something bigger happening within the category. First the hose disappeared. Then the power cord. Now charging, scheduling, docking and even emptying the onboard debris basket are becoming automated.

The Push Toward Less Human Interaction
That trajectory is familiar territory for Michaelis, whose background before joining WYBOT was in consumer robotics at iRobot.
โIn any robotics industry, your goal is to make the user experience as autonomous as possible,โ he said. โYou want as little human interaction with your robots.โ
The pool industry is beginning to follow the same path already seen in other consumer robotics categories. Navigation is becoming more sophisticated. AI-assisted systems can influence where a cleaner goes and how it approaches the pool. Battery technology has removed the tether. App connectivity provides another layer of control, while docking, solar charging and scheduled cleaning are reducing the need for owners to deploy equipment manually.
โWhere I see the robotic pool cleaning industry heading is trying to make it as autonomous as possible,โ Michaelis said, โtrying to reduce the amount of human interaction that you have with your robots, and ensuring that they’re doing the jobs that they’re set out to do.โ
For homeowners, that means convenience. For pool professionals, it can have an entirely different value proposition.
A Better Ownership Experience Builders Can Sell
For builders trying to connect with increasingly tech-savvy pool buyers, equipment has become another opportunity to differentiate the finished project.
A self-parking, self-charging and self-emptying robotic pool cleaner isn’t simply another piece of equipment sitting in the pool. It’s the kind of feature a builder can demonstrate during turnover and immediately show a customer how much of the routine maintenance process can happen automatically.
Michaelis sees that as a potential finishing touch on a premium pool package.
โOn the builder side, it’s really going back to that innovation piece,โ he said. โIt’s a surprise and delight moment at the time of purchase.โ
When builders are assembling an equipment package for a prospective pool owner, he said, โadding some self-emptying robotic pool cleaner is just the cherry on top for that customer and really provides that top-notch experience.โ
That’s an important part of WYBOT’s positioning. The company isn’t simply trying to connect with consumers shopping online for another cleaner. It’s developing features that builders, retailers, and service professionals can put in front of their own customers as part of a better pool ownership experience.
For service companies, meanwhile, the conversation moves from convenience to productivity.
Why Service Pros Are Paying Attention
Discerning service companies looking to recommend best-in-class robotic cleaning technology have good reason to gravitate toward products offering greater autonomy and less human interaction.
The robot isn’t replacing the service professional. Instead, it can work in the background during the six days between weekly service visits, continually handling a portion of the physical cleaning workload before the technician ever arrives.
Michaelis said some pool companies already view robotic cleaners as an efficiency tool rather than an optional accessory.
โWe constantly hear feedback from service companies on how many more doors they’re able to service, how many more pools they’re able to service, how quickly they can get pools done so that they can get to the next customer, and how many more they can fit within their route,โ he said.
In fact, some have made automated cleaning a prerequisite for taking on a customer.
โWe actually have some service companies that actually won’t service clients unless they have some sort of robotic cleaner in their pool so that they can be the most efficient when they’re stopping by on a weekly basis,โ Michaelis said.
That changes the role a robotic cleaner can play in the relationship between the pool professional and homeowner.
A service company recommending a premium robotic cleaner isn’t necessarily selling its customer a replacement for professional service. It’s giving that customer a machine capable of working between visits while simultaneously giving its technicians a cleaner pool to work with when they arrive.
And as those robots become increasingly autonomous, the value proposition gets stronger.
A cleaner that has to be manually deployed, retrieved, charged, and emptied still asks quite a bit from the homeowner. A cleaner capable of following a schedule, parking itself, recharging and transferring its own debris asks considerably less.
For WYBOT, that’s where the S Seriesโand particularly products such as the S3โbegins to stand out. It’s also where two decades of manufacturing robotic cleaners starts to matter more than how recently consumers began seeing the WYBOT name.
The brand may be relatively new to some pool owners and professionals, but the company behind it isn’t. Now, rather than innovating behind the scenes for other brands, WYBOT is putting that experience behind products designed to connect directly with homeowners and the professionals serving them.

Putting Nano-Set to the Test: What Plasterers Are Seeing in the Field

New products enter the pool industry every year with impressive technical claims. Getting contractors to actually change the way they work is another matter entirely.
That is particularly true in pool plastering, where experienced applicators tend to know exactly how their preferred mixes behave, how quickly they set and what to expect once a newly finished pool begins its startup. Any additive introduced into that process ultimately has to prove itself in the hands of the people doing the work.
That appears to be where Nano-Set by Sabal Green Group is beginning to gain some traction.
A liquid colloidal silicate admixture, Nano-Set was developed for cementitious pool finishes, designed to help address common plaster issues such as pigment loss, plaster dust and permeability while reducing the pH fluctuations that can make new pool startups more difficult.
Those are meaningful claims in the plaster business. They’re also the kind that contractors ultimately have to prove for themselves on actual jobs.
Jason Evans of Pool Boy Plastering is one of the plasterers who has put Sabal Green’s claims to the test.
โI’ve been talking about this product in our various pool groups and to everybody that I do business with because it’s been a really good admixture that we’ve been adding to our mixes,โ Evans said.
Evans didn’t go all-in immediately. Pool Boy Plastering initially tried Nano-Set on a few projects to see how it affected the material and, importantly, how his finishers responded to it.
โWe were kind of cautious, but once we used it, the crew liked it, and that’s very important,โ Evans said.
His finishers describe the plaster as a little โjuicier,โ with more cream available during finishing. For some newer mixes that tend to be drier, that added workability was a welcome change.
But what ultimately convinced Evans to begin using the product on every job wasn’t simply how the plaster behaved under the trowel.
It was what happened after his crews left.

Fewer Problems After the Pool Is Filled
Once a newly plastered pool fills, the curing surface and the water begin interacting. That’s when plaster dust, rising pH, staining, scaling and mottling can turn into callbacks for the contractor.
Evans had heard what Nano-Set was supposed to do. He wanted to see whether those claims held up once pools were completed and put through startup.
โWhen I first heard about it, you hear these claims, it helps with the pH on the startup, it strengthens the plaster. It prevents some issues that have always been there with cement products that are underwater,โ Evans said. โAnd you hear these claims and, finally I tested it, and sure enough, we find there’s a lot less warranty calls.โ
Mottling was one area where the difference stood out.
โWe haven’t gotten one complaint or call in regards to mottling since using the productโ Evans said. โTypically we would get a couple calls a year.โ
Operating in South Florida, Evans said his company would occasionally encounter darker areas around main drains, swim-outs and other portions of a finish where moisture could become a factor.
โKnock on wood, we haven’t had any mottling issues at all,โ he said. โThat’s a thing of the past.โ
Part of what Nano-Set is designed to address happens during the normal curing of cement. Calcium hydroxide is produced during that process, and some of it can migrate toward the plaster surface. That’s one contributor to the familiar dust that startup technicians brush from a newly finished pool and to the elevated pH they often contend with during startup.
The mixture reacts with calcium hydroxide to form calcium silicate within the cement matrix. For Evans, the chemistry becomes much easier to appreciate when the pool is filled and brushed for the first time.
โTypically when you fill a pool up, and you brush it, it gets dusty, right?โ Evans said. โAnd that’s the calcium that you’re brushing off the pool plaster. And so that has basically stopped.โ
That has changed the startup experience as well.
โIt’s just an easier startup. Much fewer chemicals. It’s just easier to balance out your water, and that tends to result in less staining,โ Evans said.
Traditionally, managing a new plaster startup can involve repeated acid additions as the pH climbs again between visits. Evans said he’s seeing considerably less of that.
โThe amount of acid that they have to add to the water to bring the pH within the acceptable range is a lot less,โ he said.
That matters during the first days and weeks when the new finish is especially sensitive to water chemistry.
โThe less chemicals you can add, the better during the startup process,โ Evans said.

What Changes for the Plaster Crew
Of course, none of those benefits would mean much to a plaster company if the additive made the material considerably more difficult to install.
There are some adjustments.
Evans said crews need to account for it in their water content. He prefers a relatively stiff mud mix and cuts the water accordingly to maintain the proper concentration.
The product also slows the set slightly. In South Florida’s summer heat, Evans said that can work in the crew’s favor, particularly on sunny walls that tend to tighten up quickly. During cooler months, his crews may change the application sequence and begin with shaded walls.
Once his finishers adjusted, Evans said they found the material quite workable.
โMy finishers describe it as a little more juicier,โ he said. โIt seems to bring more cement cream available for the finishing, so it tends to work out to be a smoother, flatter surface using Nano-Set.โ
Where Evans sees an even bigger advantage is during exposure.
Quartz and aggregate finishes have to be exposed carefully. If too much of the cement matrix is removed during water washing, rough or inconsistent areas can develop. Evans refers to those areas as washouts.
โThe real gold for us is the exposure,โ he said.
โThe material really binds it all together,โ Evans continued. โWashouts, that’s what we call overexposed areas, that’s a thing of the past, and that’s gold for us because whenever you have something like that, it always results in a minor variation in how the pool plaster looks.โ
For Evans, eliminating those variations ultimately means fewer opportunities for a customer to find something they don’t like.
โThe less variation you have, the higher your customer satisfaction is and life is a lot easier,โ he said.
Nano-Set also isn’t tied to a particular aggregate or finish system.
โIf it has Portland cement in it, you can use Nano-Set,โ Evans said. โIt doesn’t matter what aggregate, or if you have different type of pigments. It basically works with the cement and during the cement curing process.โ
Evans specifically pointed to PebbleTec, Florida Stucco and Diamond Brite as examples of finishes his company encounters in the field.
That compatibility made it easier for Pool Boy Plastering to move from testing Nano-Set to incorporating it into everyday production.
When Fewer Callbacks Pay for the Product
Adding another material to every plaster job comes with a cost, and Evans initially considered treating Nano-Set as an additional line item. His company’s annual pricing had already been established when they began testing it, however, so Pool Boy Plastering decided to absorb the expense while they evaluated the results.
As the number of completed jobs grew, Evans began looking at the cost differently.
โWe figured that we would just eat it, right? We said, let’s try out this product and it seemed to be working good,โ he said. โAnd now we kind of found that with the reduced callbacks and with the easier fire-ups, it basically pays for itself.โ
For a plaster company, a callback costs more than the drive back to the job. Someone has to inspect the finish, determine what’s happening, and often walk a builder or homeowner through how cement curing and water chemistry may be affecting its appearance.
โIf you’re not getting dark areas in your quartz finishes or your color isn’t getting calcified over, you’re getting less phone calls as a plaster installer,โ Evans said. โAnd that means that you’re able to run your business better.โ
โThe time I spend doing that is a fraction of what it used to be,โ he added, โand this is something that honestly is helping me run my business better.โ

Putting It to Work on a Showcase Pool
A recent project for Pool Crafters’ Rocky Miller gave Evans an opportunity to put that confidence to work on a much larger canvas.
The pool features a large lazy river surrounded by extensive natural and artificial rockwork. Pool Boy Plastering installed a PebbleTec Tropical Breeze finish with additional Shimmering Sea abalone shell.
Miller had spent considerable time choosing the finish and was concerned about maintaining the color he wanted without scaling eventually leaving it looking lighter. By then, Evans had already used Nano-Set on roughly 20 pools his company had completed for Miller.
โHe did notice that the startups were easier, and he hadn’t got any calls on pool scaling,โ Evans said.
That track record gave Miller more confidence in moving forward with his finish selection.
โHe didn’t have to put in a super dark surface into his pool to enjoy the blue because it would be whitewashed out from scaling over,โ Evans said. โSomething like that, it helps, especially on a big project like this.โ
The project also illustrates why Nano-Set is beginning to find a following among plasterers.

Technical data can convince a contractor to try a new product. What happens over a trial by fire determines whether it actually stays in the field.
For Evans, Nano-Set has successfully made the leap. What began as a cautious trial is now something he feels compelled to use on every job.
In a trade where experienced applicators can be reluctant to change a process they’ve spent years perfecting, that kind of adoption may say more about the product than anything else.
