Natural hydraulic lime NHL 3.5 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 EX NOVO line products combine good mechanical strength and high breathability, and are especially suitable for application on historic buildings; the finish coat render, reinforced with alkali-resistant fibreglass mesh, reduces tensions in the substrate and thus minimises the risk of hairline cracks forming, and is available in finer or coarser gradings, depending on the desired aesthetic effect. For a rustic finish, the application cycle can be completed with a silicone finish coat render; the product, ready-to-use, is available in different gradings and combines the highest water repellency and breathability values. Alternatively, the cycle can be completed using a silicone paint.
