BS 5385-2:2015

This part of BS 5385 gives recommendations for the design and installation of external ceramic, natural stone and mosaic wall tiles in normal climatic conditions in the UK. It deals with the types of backgrounds and their suitability to receive tiling using the following fixing methods:

1. bedding in cementitious or reaction resin adhesives on an intermediate substrate or as a direct bedding method;

2. bedding mosaics in cement and sand mortar on rendering or as a direct bedding method on appropriate backgrounds.

NOTE Cement and sand mortar is seldom used as the bed for external wall tiling but, if needed, see BS 5385‑1.
