Tile dry screed properly

Mainly in bathrooms but also in other rooms there is the need to tile a dry screed construction. In principle, this is easily possible if it has previously been ensured that the load-bearing capacity of the screed construction is also sufficient - this is not the case with all dry screeds. Normally, no problem is to be expected up to a tile size of 30 x 30 centimeters - if the tiles are larger, however, it should be inquired at the trade whether the screed construction needs to be reinforced.

Important: Matching the seal and tile adhesive

If the screed elements are protected with a special sealant, it is important to ensure that the tile adhesive used is also compatible with this sealant and does not lose its adhesive power. Without sealant, only those tile adhesives may be used which are especially suitable for dry screed. In principle, only really matching products should apply here. Especially the seal of the joints must be carried out cleanly, it is best to use joint sealing tapes here.

If necessary: ​​compact the fill, increase the fill

If heavier or larger tiles are laid, such as porcelain stoneware, a suitable (cement-bound) bed should be laid in each case. The dumping height should be increased slightly and the packing should also be compacted if necessary. It is important to note that piles must always be compact when installed and not loose - this rule applies even more when tiled on dry screed. Decoupling is generally not used in practice. In most cases, other types of bulk material, higher compaction and a higher bulk level are avoided at the boundary. Regardless of the advice that you should find everywhere in terms of weight and tile size, in any case, the manufacturer's information is respected, since in case of damage can only be claimed. Cover heights of pipes in the screed - or in the fill - must always be adhered to in the same way.
