What is the recommended mortar mix for the bedding?

A cement-sand mortar ratio of 1:4 by volume is recommended for the bedding (Clause 4.2.1).

What should be the thickness of the mortar bed?

The average thickness of the mortar bed should be between 15 mm and 20 mm (Clause 6.1.1).

How long does vitrified tile flooring need to be cured?

The flooring should be cured for a minimum of 7 days by ponding with water or covering with wet gunny bags (Clause 8.2).

Can I use neat cement slurry to fix the tiles?

Yes, a thin layer of neat cement slurry (2 mm thick) should be applied on the fresh mortar bed just before placing the tile (Clause 6.1.1).

This code of practice outlines the procedure for laying vitrified tiles on flooring. It covers material specifications, preparation of the sub-base, the laying process using cement mortar, as well as finishing operations like grouting, cleaning, and curing.

Provides recommendations for the proper method of laying vitrified tiles for flooring applications.

Practical Notes

Vitrified tiles have very low water absorption, so unlike ceramic tiles, they should not be soaked in water before laying as it can hinder bonding.

While this code focuses on the traditional mortar bed method, modern practice often uses tile adhesives (conforming to IS 15477) for better adhesion, faster work, and laying large format tiles.

Proper preparation and cleaning of the sub-floor is critical to prevent future issues like tile debonding or cracking.
