Biokil Crown Biodry DPC Cream – 5L High-Performance Injection Cream for Long-Term Rising Damp Protection Biokil Crown Biodry DPC Cream (5L) is a silane/siloxane-based injection cream developed to stop rising damp in brick, stone, and mortar constructions. Formulated for deep penetration and permanent water repellency, it creates an effective chemical damp-proof course (DPC) once injected into mortar beds. Supplied in bulk for large-scale application, it is ideal for professional use in refurbishment and remedial damp-proofing works. The cream is odourless, solvent-free, and easy to apply using standard electric or manual injection pumps. It diffuses into the wall substrate and reacts with moisture to form a durable barrier, preventing moisture from rising through capillary action. Key Features & Benefits Long-Term Damp Protection: Effectively controls rising damp by forming a water-repellent barrier. Silane/Siloxane Formula: Deep penetrating chemistry ensures excellent diffusion and durability. Ideal for Large Projects: Supplied in 5L container for efficient application across multiple walls or properties. Low Hazard: Odourless, solvent-free, and suitable for use in occupied buildings. Compatible Substrates: Suitable for solid wall construction including brick, stone, blockwork, and mortar. Product Details Type: Silane/siloxane-based DPC injection cream Form: Cream Colour: White (becomes translucent during diffusion) Container Size: 5 Litres Coverage: Approx. 41–43 linear metres of 215mm thick solid wall (depending on application method and substrate) Application Tools: Electric or manual injection pump Application Instructions Drill Holes: Drill 12mm holes horizontally into the mortar course at 120mm intervals, typically 150mm above ground level. Inject Cream: Use a suitable pump to inject the cream from the back of the hole to the front in one continuous motion. Allow to Cure: The cream will migrate into the surrounding substrate and cure to form an effective DPC. Finishing: Plug holes and apply salt-resistant plaster or render if required. Limitations Do not apply to saturated or waterlogged walls. Not suitable for use on gypsum plaster or timber surfaces. Health & Safety Wear gloves and eye protection during application. Ensure adequate ventilation in enclosed areas. Refer to the Safety Data Sheet (SDS) before use.
