This Indian Standard ( First Revision) was adopted by the Indian Standards Institution on 26 June 1972, after the draft finalized by the Flooring and Plastering Sectional Committee had been approved by the Civil Engineering Division Council. The usefulness of tiles as flooring material consists mainly in their pleasant appearance as it eliminates the possibility of unsightly cracks and facility for quick installation. The appearance and the performance of the tiled floor will, however, depend not only on the quality of materials used but also on the care taken in bedding, laying and finishing of the tiles. This standard gives necessary guidance in the laying of cement concrete tile flooring to obtain good appearance, durability and finish. This code of practice lays down procedures for the preparation of bedding and for the fixing and polishing of plain terrazzo and special types of cement concrete flooring tiles. Precautions necessary in the finishing of skirting, dado, staircase treads, etc, are also dealt with. The code includes the materials used in fixing, grouting and polishing of tiles, and in the maintenance of the tiled flooring. This standard which was
first published in 1959 is now re%sed taking into account the experience gained in this work since then. The salient features,of this revision are given below:
a) Preparation and use of cement mortar and lime mortar for bedding concrete tiles have been separately described,
‘b) Details pertaining to grinding and polishing of tiles after laying are given, and
c) Permissible tolerance in laying of tiles has been specified.
In the formulation of this standard due weightage has been given to international co-ordination among the standards and practices prevailing in different countries in addition to relating it to the practices in the field in this country. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960*.
