The tiling method currently widely used in Europe is the so-called thin-layer bonding method, that is, a toothed spatula is used to scrape the polymer-modified tile adhesive batch on the surface of the base layer to be tiled in advance to form raised stripes and uniform thickness of mortar layer, then press the tile on top of it and twist slightly, the thickness of the mortar layer is about 2 to 4 mm . Due to the modification effect of cellulose ether and redispersible polymer powder, the use of this tile adhesive has good bonding properties to different types of base layers and surface layers including fully vitrified tiles with extremely low water absorption. Good flexibility to absorb stress due to temperature differences, etc., and excellent sag resistance, long enough open time to greatly speed up application in thin layers, easy handling and no need to pre-wet the tiles in water. This construction method is easy to operate and easy to carry out on-site construction quality control.
