Biokil Crown Biodry DPC Cream - 1L

Professional Damp Proof Injection Cream for Rising Damp Control

Biokil Crown Biodry DPC Cream is a high-performance silane/siloxane-based damp proofing solution formulated to prevent rising damp in masonry walls. Delivered as a ready-to-use cream, it is injected into mortar beds using a standard caulking gun, where it penetrates deeply and reacts with the substrate to form a durable chemical damp-proof course (DPC). Ideal for brick, stone, and mortar constructions in both residential and commercial properties.

Key Features & Benefits

• Effective Rising Damp Control: Forms a long-lasting chemical barrier against moisture migration through masonry.
• Easy Application: Fits standard 1L skeleton guns – no special equipment required.
• Low Odour & Non-Hazardous: Safe and clean to use in internal environments.
• Deep Penetration: Silane-rich formula ensures thorough diffusion into porous materials for optimal protection.
• Suitable for Various Substrates: Compatible with brick, stone, blockwork, and mixed masonry walls.

Product Details

• Size: 1 Litre tube
• Form: Silane/siloxane-based cream
• Colour: White (becomes translucent as it diffuses)
• Coverage: Approx. 8–10 linear metres in 215mm thick solid walls (based on typical drilling patterns)
• Application Tools: Standard skeleton gun

Application Instructions

1. Preparation: Drill 12mm diameter holes horizontally into the mortar joint at 120mm centres.
2. Injection: Fill each hole from the back to the front in a smooth, continuous motion.
3. Penetration & Cure: The cream will migrate into the substrate and form a chemical DPC upon curing.
4. Finishing: Holes can be plugged and internal walls replastered using a salt-resistant render if necessary.
