AS 3958.1-2007

Provides guidance on the preparation of the background and the fixing and grouting of floor and wall tiles and mosaic tiles. Information for application in swimming pools, gradients on floors, screeds and rendering, and cleaning and maintenance is also included.

This Standard provides guidance on the preparation of the background and the fixing and grouting of floor and wall tiles and mosaic tiles. It also provides information on the application of tile in swimming pools, gradients on floors, screeds and rendering, and cleaning and maintenance.Specialized applications such as the need for chemical resistance and the use of epoxies are not considered in detail.This Standard applies to all work involved in the internal and external laying of ceramic wall and floor tiles. It deals with the types and classes of backgrounds and substrates and their suitability to receive a bedded finish using the following fixing methods, which are also described in the relevant sections:(a) Bedding in sand/cement mortar on rendering or as a direct bedding method.(b) Bedding in cement-based adhesives on an intermediate substrate or as a direct bedding method.(c) Bedding in organic-based adhesives on an intermediate substrate or as a direct bedding method.(d) Bedding in other adhesives on an intermediate substrate or as a direct bedding method.Mosaic tiles constitute a specialized form of tiling and those aspects of fixing that require particular treatment are dealt with in this Standard.The recommendations relate to mosaics assembled in the form of sheets, the separate pieces being glued either face down to paper or bedding, side down to nylon adhesive strips, fabric net or other material.Where tiling is to be carried out in wet areas, the recommendations in AS 3740 should be considered, particularly with regard to the preparation of the background.The designer should make know to the tiling contractor any structural or environmental conditions such as excessive deflection or the likelihood of excessive or delayed shrinkage onset of the substrate.Recommendations for tiling in situations where with specific functional or environmental requirements are provided in BS 5385.4.
