Unfortunately, very few painting contractors test the substrate for damp before painting. If a coating is applied to a surface where the moisture content is higher than 10%, the application is very likely to fail.
At SUPERSEAL, we use the latest technology to test the moisture content in a wall or substrate. SUPERSEAL are graduates in understanding how water works and how to ensure that a surface is not just waterproof, but damp proof and not prone to vapourisation and condensation. We do a five-stage inspection test. If any water pools and fails to evaporate within 36 hours, then appropriate surface preparation needs to be undertaken. Often issues of water ingress are addressed by applying flashing solutions, membrane, bitumen or silicone applications. While these solutions can work in some instances, often if the real issue of the water flow is not adequately addressed, the water ingress will persist.
