Tiling of uneven surfaces

Common issues and queries you can face

Achieving a flat finished

Using a notched trowel at a constant angle provides an even distribution of adhesive onto the substrate. If the tiles are all bedded with a similar force they should be at the same height with only minimal unevenness. 

However, if the substrate is not properly leveled, there is a higher chance that some edges will dent and stand out of the final surface.

Filling multiple holes

Localized deep holes, may result in a bed thickness that exceeds the specification for a thin bed adhesive application. Patching and leveling such holes and slumps can be time consuming if they are numerous.

Combination of problem

In some instances, when tiling over a layer of existing ceramic tiles, the mentioned problems may be combine all at once, which will require that some of the tiles to be removed.

Some natural stones vary in thickness

Non calibrated natural stones are stones that have been split along their natural fracture planes rather than machine cut. The result is a stone that varies in thickness and varies from other stone pieces. These types of stones require an adhesive that can be applied at a greater thickness than normal.
