Fila PW10 Eco-Compatible Pre-Laying Treatment Against Efflorescence 5L

Fila PW10 is an advanced efflorescence-blocking sealant that's specifically formulated for application to the back of tiles, natural stone, and absorbent paving slabs before installation. It creates a protective barrier that prevents contaminants such as salts, tannins, oxides, and other substrate-borne impurities from migrating to the surface, effectively eliminating the risk of unsightly stains, streaks, and efflorescence.

Combining water-repellent and consolidating properties, the treatment penetrates deeply into the material without forming a surface film, allowing the substrate to remain fully breathable while delivering long-lasting protection.

The sealant is engineered to maintain the bonding performance of adhesives and complies with UNI EN 1348:2009 and ASTM C482-02 R-2009 standards, ensuring it does not significantly alter glue adhesion characteristics.

When applied to natural stone, concrete, and other absorbent materials after installation, it provides additional protection against blackening caused by smog, atmospheric pollution, carbonation, sulphation processes, and biodeterioration, helping surfaces retain their original appearance for longer.

Environmentally responsible and suitable for indoor and outdoor use, the product is A+ classified under French VOC regulations, certified to EMICODE EC1 Plus and LEED (ACP) standards, VOC-free, and awarded the INDOOR AIR COMFORT GOLD certification.
