Ceramic Tiles In Pure Cement Mortar

Mortar is made of cement and sand in proportions of 1:4 or 1:5, and water, giving it the consistency of damp earth. It is laid to a thickness of 2.5-3 cm and evened out. A thin cement and sand grout (1:1) isthen poured on and spread with atrowel. Maximum grain size for the sand should be 2 mm.The tiles are knocked in with a rubber hammer. After afewdays of setting, the joints are filled with a cement and sand grout (1:1-3), the maximum size of grain being 1 mm. After jointing a dry version of the jointing material is spread over the whole surface in a thin layer. This lies in place until the laying pattern of the tiles becomes visible.The surface isthen cleaned, and thefloor is ready after four days curing.

Wall tiles are mounted in almost the same way with the same mix of cement and sand. It is an advantage if the back of the tile is textured and has a semi-porous surface.
