Hydrated lime dehumidifying rendering cycle for stone walls affected by rising damp. The dehumidifying cycle involves application across the entire surface of a sulphate-resistant undercoat and a macroporous render, no less than 25 mm thick; the macropores inside the latter are able to capture more salts than traditional renders. The PURACALCE line products ensure high substrate breathability; the finish coat render, reinforced with alkali-resistant fibreglass mesh, reduces tensions in the substrate and thus minimises the risk of hairline cracks forming. To obtain a smooth finish and maintain breathability of the substrate, a hydrated lime mineral smooth coat can be used; this will then be protected by a silicone paint to ensure suitable water repellency.
