⚡ At a Glance
- • Water Repellency: Penetrating cream forms an invisible, single-coat water repellent barrier
- • Best for: Owners and contractors protecting external brick, stone and mortar surfaces
- • Not ideal for: Surfaces not listed in the description, or where a coloured finish is required
Cream-based formulation soaks into porous masonry to create an invisible barrier in a single coat. Colourless finish preserves the natural appearance of brick and stone.
Long-lasting moisture protection - thanks to cream-based deep penetration
The cream formulation penetrates porous masonry, filling capillaries and creating a water repellent barrier after a single application. The manufacturer specifies a 25 year protection claim and independent approvals back performance.
Reduced water ingress helps prevent damp-related damage and reduces the risk of costly repairs. Walls stay drier, which helps internal and cavity wall insulation remain effective.
Keeps the original look - with a colourless, clear finish
A colourless formulation cures to an invisible finish, so treated surfaces retain their natural appearance. User feedback notes a clear, non-gloss finish after drying.
Ideal for conservation projects and traditional brickwork where appearance matters. The clear finish avoids the need for redecoration or matching paint.
Maintains breathability and insulation performance - thanks to a breathable formulation
Breathable chemistry allows moisture vapour to pass through the masonry so walls can dry naturally. The formulation is designed to preserve the thermal properties of cavity wall insulation.
Trapped moisture is less likely to accumulate, which helps avoid insulation degradation and cold spots. Breathable protection supports long-term wall health without sealing in damp.
