PROCESS OF WATERPROOFING

ACRYLIC/POLYURETHANE/LATEX/MEMBRANES

Bathrooms need to be waterproofed correctly by a certified licensed contractor as part of the  requirements outlined by QUEENSLAND legislation. If not the risk of structural damage resulting from dampness, water leaks, or condensation can be a major problem leading to very expensive Damage sometimes Structural. 

Before beginning the process of Waterproofing it is very important that all the surfaces are correctly prepared and primed with correct primer for the surface. Drains in the floor should be recessed for greater fall  Ensure that the surfaces are clean, dry and free of any foreign objects e.g ,steel, silicone,can be a problem for waterproofing membranes. It is recommended you follow manufacturers guidelines and application methods to comply with the exact Australian standard and extent. Then the process is usually a Primer then a  Two coat system which requires one coat at a time with the recommended amount of drying time between coats. With the top coat that is a finished product or  trafficable it is recommended to apply in a different direction to the first for example, if the first coat was put on vertically, the second should be horizontal. Waterproofing is finished when dry to manufacturers specifications.
