Professional-Grade Damp Proofing Cream for Treating Rising Damp in Masonry
Dryzone Damp Proofing Cream is a high-strength, silane/siloxane-based formulation developed to stop rising damp in brick, stone, and mortar walls. Designed for easy and mess-free application with a standard 310ml cartridge gun, it forms a permanent chemical damp-proof course (DPC) that penetrates deeply into the substrate. Ideal for both professional tradespeople and DIY users looking for a reliable, BBA-certified rising damp treatment.

- BBA Certified: Independently approved for damp-proofing effectiveness (Cert. 97/3363).
- Quick & Clean Application: Fits standard 310ml caulking guns – no specialist tools required.
- Effective Damp Control: Stops rising damp by forming a chemical barrier within the mortar course.
- Suitable for Various Walls: Works in brick, stone, and mixed masonry constructions.
- Low Waste: Ready-to-use, non-drip formulation ensures accurate dosing and minimal mess.
