BioDry ProFlow Water-Based Damp-Proofing Fluid - Ready to Use - 25L
Professional-Grade DPC Injection Fluid for Rising Damp Treatment
BioDry ProFlow RTU (Ready-to-Use) is a pre-mixed, water-based potassium methyl siliconate solution designed to create an effective chemical damp-proof course (DPC) without the need for on-site dilution. Suitable for low-pressure injection into mortar beds, it provides convenient and reliable rising damp protection for domestic, heritage, and light commercial projects.
Key Features & Benefits
- Water-Based Formula: Non-flammable and easy to handle, ideal for sensitive indoor environments.
- Cost-Effective: High dilution rate (1:11.5) makes 2L concentrate yield up to 25L of ready-to-use solution.
- Effective Against Rising Damp: Forms a continuous barrier in the mortar bed to prevent moisture transfer.
- Low-Pressure Injection: Suitable for use in residential and heritage buildings with minimal disruption.
- Versatile Application: Effective in solid brickwork, stone, rubble-filled walls, and cavity walls.
- Freeze-Tolerant: Unaffected by freezing; suitable for storage and use in cold conditions.
Application Areas
- Rising damp in brick and stone walls
- Remedial damp proofing in existing buildings
- Heritage and conservation properties
- Solid, cavity, and rubble-core walls
Preparation & Application
- Surface Prep: Remove skirtings, plasters, and damaged renders. Rake out mortar beds to 10–15mm depth. Clean debris for adhesion.
- Drilling: Drill 10–14mm holes into or angled towards mortar beds. Spacing ≤170mm. Drill both sides for thicker or cavity walls.
- Injection: Dilute 1 part BioDry ProFlow with 11.5 parts clean water. Inject under 50 psi until mortar bed is fully saturated.
- Finishing: Plug holes and allow walls to dry before replastering. Use a bell-mouth render detail where external render was removed.
Technical Specifications
- Composition: Potassium methyl siliconate
- Mix Ratio: 1 part concentrate to 11.5 parts water
- Coverage: ~2.5L per metre for 230mm thick wall
- Application Method: Low-pressure injection (5–50 psi)
- Appearance: Clear, colourless fluid
- Packaging: 2L jerrycan or 25L container
- Storage: 2 years unopened; diluted solution lasts 6 months
Post-Treatment Recommendations
- Replaster using appropriate salt-resistant renders
- Do not decorate with vinyl paints or wallpapers for 9–12 months
- Maintain good ventilation to aid drying
