It is important, both for appearance and for safety, that the finished tile surface is flat with no tiles standing higher than the others. Usually this is easy to achieve when tiling onto a flat and level surface, but if the substrate isn’t flat various problems can arise.
There are a number of possible solutions for tiling an uneven floor depending on the condition of the substrate. Deep holes must be filled first with a repair mortar. A levelling compound will give a smooth surface, but this does not help with uncalibrated stone where a thick bed adhesive must be used.
For holes in the substrate which are greater than 20mm in depth, a repair mortar may be the best option. Ensure that any loose or unsound material is removed and that the edges are cut square, not feathered.
Fill the holes with webercem pyrapatch and allow to fully cure.
A levelling compound can be used to smooth out irregularities holes and gaps between existing tiles and provide a flat and level surface for tiling. Ensure that the surface is clean, dry and sound. Any existing tiles must be firmly adhered.
Prime the substrate with weber PR360 and allow to dry. Pour weberfloor flex levelling compound to the required thickness. Make sure that any movement joints in the substrate are carried through the screed and tiling layer.
For uncalibrated natural stone tiles you will require a thick bed tile adhesive to even out the natural irregularities in the tile. This can be used to even out smaller irregularities in the substrate if a levelling compound wasn’t applied. Make sure all loose or unsound material is removed and fix tiles with weberset thick bed, which can achieve a bed thickness of up to 20mm.
If using ceramic or porcelain tiles which are uniform in shape (i.e. not uncalibrated or natural stone) fix tiles with weberset plus or weberset rapid plus.
Fill the tile joints with either:
Finish with weberjoint silicone sealant (colour-matched to our full range of grout colours, as well as a clear option) to seal perimeter.
