Compressed Fibre-Cement Sheet is a common and durable flooring material used for decks, verandahs and internal floors. It is particularly effective when used in wet-area floors such as bathrooms and showers. In this bulletin we will look at the surface preparation required to obtain a good bond for ceramic tile adhesives and membranes.
How to Reconstruct, Waterproof & Tile a Shower Recess [TB132]
This “How To” brochure details the ideal procedure to reconstruct a domestic shower recess. Included are various surfaces likely to exist in a normal building structure and various types of recess available on the Australian market. If other substrates or shower recess types are encountered, simply contact the Ardex office in your state for expert advice about your particular requirements. In all situations discussed in this bulletin, the waterproofing membrane is applied over a mortar screed that has been laid to falls.
Maintenance Recommendations for Liquid Applied Membranes [TB208]
