Boost the durability and water resistance of your concrete, brick and natural stone surfaces with Crommelin Enhance WSi 15L. This advanced water‑based penetrating sealer soaks deep into porous substrates to create a highly water‑repellent barrier, which helps prevent moisture ingress and suppresses efflorescence without drastically altering the surface’s natural look. Because it lets surfaces breathe while improving cleanability, it’s a smart choice for both residential and commercial concrete areas.

Rather than forming a surface film, Enhance WSi uses a combination of polymer particles that fill varying pore sizes to block water pathways yet maintain vapor permeability. Therefore, it provides long‑lasting moisture protection and helps reduce issues like spalling over time.

Key Features:

• Penetrating water‑based sealer engineered for concrete, pavers, brick and stone substrates.

• Delivers high water repellency while still allowing the surface to breathe.

• Helps suppress efflorescence and impede moisture passage, reducing surface staining.

• Enhances cleanability and maintains a natural, matt finish.

• Low odour and water‑based for easier application and cleanup.

Ideal For:

• Concrete driveways, patios and walkways

• Clay brick, sand‑set pavers and exposed aggregate

• Natural stone, sandstone and reconstituted limestone

• Mortar, grout and other porous masonry surfaces

Application & Benefits:
First, ensure the surface is clean, dry and free from dust and contaminants. Then apply Enhance WSi evenly using a brush, roller or low‑pressure spray. As it penetrates, polymer particles block capillaries and voids, creating a durable water‑repellent layer that improves resistance to moisture and surface staining without making the surface slippery or glossy. Follow manufacturer instructions and test on a small area first to confirm results.
