Stop a Major Factor in Wet Area Leaks – Select the Correct Tile Adhesive & Correctly Apply It!

Correct use of tile adhesives can help prevent wet area leaks.  Spot fixed tiles allow water to track behind tiles and are often the cause of wet area leaks.  Correct application of the tile adhesive is to back butter any tiles over 400mm x 400mm, using a 12mm notch trowel.  This will prevent water tracking and leaking from the wet area.

Selection of the correct tile adhesive for the job is critical.  Tile adhesives are classified based on their composition, curing method and tensile adhesive strength.  For instance, a C2 adhesive is cement based and improved to have greater tensile strength.  To determine the best tile adhesive for the job, check with tile adhesive manufacturers.

 

Installation Points
Back butter tiles greater than 400mm x 400mm using a 12mm notch trowel.

Installing tiles over a set height requires the addition of mechanical fixing.  Check with the tile adhesive manufacturer and BRANZ Good Tiling Practice Guide for requirements.

 

Limitations
Ensure full adhesive coverage is achieved (no adhesive voids, as the void will allow water to migrate behind the tiles and build up quickly, leading to water escaping the shower cubicle or room).

Always refer to the manufacturers specific installation manual instructions and the BRANZ Good Tiling Practice Guide.

Do not tile over the water stop in the shower recess.  A minimum of 5mm above the tile helps maintain a vessel type area within the shower cubicle.
