⚡ At a Glance
- • Waterproofing Performance: Silicone hydrophobic treatment lines pores and causes water to bead off surfaces
- • Best for: Homeowners and DIY renovators treating exterior brick, stone and mortar surfaces
- • Not ideal for: Situations that require a coloured or decorative coating
Silicone hydrophobic technology modifies the substrate surface and lines pores to create a water-resistant coating. A breathable, water-based formula cures quickly while preserving the natural look of masonry.
Keeps Masonry Dry – With silicone hydrophobic technology
Silicone hydrophobic molecules bond to the substrate and line capillaries, creating a water-repellent layer that prevents liquid penetration. Pore-lining changes surface behaviour so water beads rather than soaks into masonry.
Water runs off walls instead of being absorbed, reducing damp marks and salt damage. Rain resistance helps protect external brickwork and stone from weather-related wear.
Allows Walls to Breathe – Thanks to a breathable waterproof barrier
Formulation creates a vapour-permeable coating that stops liquid water while permitting water vapour to escape through the substrate. Breathability prevents trapped moisture behind the treated surface.
Moisture from inside masonry can still evaporate, lowering the risk of blisters and trapped damp. Suitable for historic or porous masonry where vapour movement matters.
Colourless, Low-odour Finish – With a solvent-free, water-based formula
A water-based, low-VOC composition avoids solvents and heavy smells, enabling quicker curing and less odour during application. The clear formulation does not obscure the substrate's natural surface.
Natural brick and stone appearance remains visible after treatment, ideal for conservation and aesthetic upkeep. Quick curing and low odour make the product practical for domestic DIY projects.
