Tiled floors are most often used in the bathroom and toilet rooms. Before laying tile floors, waterproofing should be done on the floor slabs, as these rooms are the most dangerous for flooding. Waterproofing is performed from one or two layers of roofing material laid on hot bituminous mastic. Roofer sheets should overlap by 15–20 cm. A mortar screed 15–20 mm high or higher is made along the ruberoid carpet if communications are laid in the floors. Screed is similar to screed for parquet. In this case, due to the insignificant thickness of the screed, the board needs to be laid flat. Having poured a strip 1 m wide or narrower, tile is laid in the solution that has not set. Tile is cut in the same way as when facing walls. On the floors you can use broken tiles of different colors, laying it like a mosaic.
After laying the tiles, unfilled seams are filled with mortar. Then the floor is covered with sawdust, and when the solution sets, sweep them along with dirt and dried solution.
