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 plasters or renders.
The PURACALCE line products ensure high substrate breathability; the finish coat render, reinforced with alkaliresistant fibreglass mesh, reduces tensions and thus minimises the risk of hairline cracks forming. For a final rustic effect, the application cycle can be completed with a ready-to-use silicone finish coat render, available in different gradings and combining the highest water repellency and breathability values. Alternatively, the cycle can be completed using a silicone paint.
