Description

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.

Key Features & Benefits

  • 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.

Product Details

  • Size: 310ml cartridge
  • Form: Silane/siloxane damp-proofing cream
  • Colour: White (fades as it penetrates)
  • Coverage: Approx. 2.5 linear metres per 310ml cartridge in a 215mm thick solid wall
  • Application Tool: Standard skeleton or mastic gun

Application Instructions

  1. Drill Holes: Drill 12mm diameter holes into the mortar bed at 120mm centres, typically 150mm above ground level.
  2. Inject Cream: Fill each hole from the back to the front using a smooth, continuous action.
  3. Allow to Cure: The cream will diffuse and cure within the wall, forming a damp-proof barrier.
  4. Replastering: Use a salt-resistant plaster or renovating render after DPC installation if necessary.
