Pool Tile Installation Starts With Using Proper Materials

Proper pool tile installation on vanishing edge walls will prevent clients from thinking that the pool wall is leaking.

It all starts with using the proper pool tile material. Once water begins to infiltrate behind the tiles of the swimming pool, a whole bunch of problems can arise.

Efflorescence in Pool Tile

Efflorescence is carried to the surface from the shotcrete, thin-set or grouts. Even epoxy setting materials can promote efflorescence.

When It Comes to Pool Tile Installation, Setting Materials Make a Difference

Epoxy setting materials are not 100% epoxy. Many still contain cement-based components. The technical sheets for most epoxy thin sets and grouts contain a disclaimer about efflorescence.

Water Getting Behind The Tile

After the vanishing edge is turned off, areas on the wall may continue to be wet for hours – simply from water trapped behind the tiles. This is where many pool tile failures occur.

Water streaming out of cracks in the grout when the vanishing edge system is on, is another indication of voids behind the tiles.

But when a customer sees any sign of water on the “dry side” of the wall, they immediately think the wall is leaking. While this may sometimes be the case sometimes, in most instances, it is merely an improper tile installation.

Prevent Tile Failures – Know The Codes

The TCNA specifies that 95% of the tile must be in contact with thin-set. This can be achieved by back buttering and knocking down the comb/gauge marks. Failing to provide movement joints causes the corners to split and crack as well.
