- SilaSeal is a water-based silane-siloxane sealer used for sealing porous reconstituted and natural stone, clay and concrete materials.

- Suitable for garages, walls, roofs, entertaining areas, kitchens and wet areas, pool surrounds, patios, driveways.

- It is not, however, recommended for use on very dense substrates.

Si Sealers C - Siliconates, Silanes & Siloxanes

Si Chemistry: Si based water repellent sealers are usually applied in the form of siliconates, silanes and/or siloxanes. They are typically very small to medium sized molecules that when applied onto a substrate, penetrate deep below the surface. They chemically react with the substrate to form a cross-linked Si backbone polymer which repels water whilst still allowing vapor transmission.

Key advantages

    • Superior water repellence, providing excellent water-based stain resistance;
    • Reduces water ingress and minimises efflorescence in mineral substrates;
    • Transparent, natural finish - does not significantly change appearance;
    • High penetration into masonry surfaces;
    • High wear resistance, UV stable, long life;
    • Fungal and algal resistance;
    • Easy to clean surfaces;
    • Substrates remain breathable;
    • Can be applied to damp or wet substrates.
