Description
Hydrophobic Brick Sealing Siloxane – Waterproof Protection & Energy Efficiency for Brickwork
Protect and preserve your brickwork with this hydrophobic siloxane brick sealer — a high-performance waterproof coating designed to prevent moisture ingress, reduce damp, and improve energy efficiency.
This advanced formula creates a breathable, flexible barrier that keeps brickwork dry while allowing trapped moisture to escape, ensuring long-term structural protection.
Advanced Brick Protection That Performs
- Hydrophobic Water Repellence – Prevents water ingress and damp issues
- Breathable Coating – Allows vapour to escape, reducing trapped moisture
- Mould & Algae Resistant – Protects against moss, algae, and organic growth
- Flexible & Crack-Resistant – Adapts to expansion and contraction during weathering
- Energy Efficiency Boost – Helps reduce heat loss by keeping walls dry
- Low VOC Formula – Environmentally friendly and safe to apply
- Fast Drying – Ideal for efficient project completion
- Clear or Coloured Finishes – Available in clear or RAL/BS options
Built for Long-Term Brickwork Protection
