D.   CEMENT MORTAR BEDDING :

Cement mortar screed in the proportion 1:4 shall be laid on the concrete base as per the thickness required to achieve the level of the tiles. The level of the finished floor shall be marked on the adjoining walls and shall be used as a reference to determine the thickness of the mortar screed.

The level of the tiles shall be checked from time to time with the help of a straight edge and string used for reference attached to a reference tile placed in the corner of the room. Plastic spacers shall be fixed at the corners of the tile and the adjoining tile shall be placed leaving a space equal to the spacer between the tiles.
