Tradilys Protect – Damp Treatment Plaster - Damp Treatment Plaster

Tradilys Protect differs from standard lime renders because it is not just a breathable finishing plaster coating — it is a dehumidifying and salt-management render system specifically formulated for problematic, damp and contaminated masonry.

Tradilys Protect is a high-performance, durable, cement-free mortar formulated with natural hydraulic lime (NHL 3.5) and designed specifically to renovate walls affected by rising damp and salt contamination.

This macroporous, dehumidifying render features a natural, highly breathable composition, making it suitable for both internal and external applications. A natural, cement-free option, Tradilys Protect maintains the natural breathability, allowing moisture to dissipate without damage to the structure of the building.

Developed to remediate masonry damaged by saltpetre and moisture, it effectively manages chlorides, nitrates, and sulphates through its salt-buffering capability. Its very low capillary absorption reduces further moisture ingress while encouraging rapid evaporation of retained water, helping walls dry efficiently and safely. Carefully selected admixtures enhance flexibility and provide a smooth, workable consistency suitable for both manual and mechanical application.

Features and benefits:

• Traditional mortar designed for restoring walls affected by saltpetre and dampness.
• Suitable for applying renders and plaster layers to address capillary rise and various salts (chlorides, nitrates, and sulphates).
• Special additives enhance flexibility, making application easier.
• Complies with DTU 26.1 standards.
• Soft and creamy mortar suitable for machine wash and manual application.
• Adhesion to substrates is optimised by the presence of lime.
• Natural hydraulic lime mortar, cement-free
• Formulation adapted to the treatment of salts
• Very low capillary absorption allows rapid evaporation of humidity
• Reduced consumption (coverage from 50 cm above humidity)
• Mechanical resistance adapted to heritage construction
