Wykamol Renovation Plaster – BBA Approved, Fibre-Reinforced Damp-Proof Plaster
Wykamol Renovation Plaster is a BBA-approved, fibre-reinforced, lightweight cement/lime plaster designed for replastering after the installation of a damp-proof course (DPC). It effectively controls dampness and salt migration while allowing walls to breathe and dry naturally.
The high-performance formula includes perlite aggregates to reduce heat loss and condensation, improving thermal efficiency. Incorporated fibres prevent cracking and crazing, while waterproofing additives enhance durability and protection.
Key Benefits:
✔ BBA Approved – Independently tested for long-lasting damp-proofing performance.
✔ Breathable & Salt-Resistant – Allows moisture to evaporate, preventing damage.
✔ Fibre-Reinforced – Eliminates cracking and crazing for a smooth, durable finish.
✔ Thermal Insulating Properties – Reduces condensation and enhances energy efficiency.
✔ Prevents Mould Growth & Rusting of Fixtures – Protects embedded metals like angle beads & conduits.
✔ High Coverage Rate – 3–4m² per 25kg bag at 10mm thickness, ensuring cost-effective application.
✔ Compatible with Wykamol Damp-Proofing Systems – Works with chemical DPC injections, tanking slurries, and waterproofing coatings.
Ideal Applications:
✔ Replastering after DPC Installation (Chemical Damp-Proof Course or Tanking Systems)
✔ Basements, Cellars, and Damp-Affected Walls
✔ Heritage & Conservation Properties (Suitable for traditional lime-based repairs)
✔ Insulating & Protecting Walls from Salt Contamination
Application Guidelines:
📌 Apply in coats of 10–15mm thickness (multiple coats for thicker applications).
📌 Leave to set for a minimum of 24–48 hours before skimming or painting.
📌 Only use breathable finishes like permeable paints initially (avoid vinyl paints, wallpaper, or tiles until fully dry).
Wykamol Renovation Plaster – Technical Specifications
Coverage per Bag
-
Yield: Approximately 3–4 m² per 25 kg bag when applied at 10 mm thickness.
-
Efficiency: Lightweight, with perlite aggregate, reducing heat loss and condensation while providing excellent coverage.
Recommended Application Thickness
-
Base Coat Thickness: Apply in coats of 10–15 mm thickness. Avoid exceeding 12 mm per coat for proper curing.
-
Layering for Thick Applications: For overall thickness greater than 20 mm, apply in multiple layers with drying time between coats.
-
Total Thickness: Typically, a two-coat application results in 15–20 mm total thickness, ideal for damp-proofing.
Drying and Curing Times
-
Initial Set: Approx. 7 hours under normal conditions.
-
Before Finishing Coat: Minimum 24 hours, preferably 48 hours, before applying skim coats or paint.
-
Full Cure / Drying: May take several months for walls with previous damp issues before applying impermeable finishes.
Substrate Preparation & Priming Requirements
-
Remove Old Material: Strip all old gypsum plaster, paint, and loose debris.
-
Keying the Surface: Rake out mortar joints and roughen smooth surfaces for better adhesion.
-
Priming: Dampen high-suction backgrounds or use Wykamol SBR primer for better bonding.
-
Avoid Bridging Damp-Proof Course: Leave a 50 mm gap above floor level to prevent moisture bypassing the DPC.
-
Angle Beads & Metal Fixtures: Use stainless steel corner beads and non-gypsum fixing methods to avoid corrosion.
Compatible Finishes & Decoration
-
Skim Coat Finish: After 24–48 hours, apply a 2–3 mm finishing coat (e.g., Thistle Multi-Finish or Wykamol High Impact Plaster).
-
Paint & Decoration: Use breathable emulsion paints; avoid wallpapers, vinyl paints, and tiles until the wall is fully dry.
-
Compatibility: Works with Wykamol damp-proofing systems (e.g., tanking slurries, injected DPC treatments).
By following these guidelines, Wykamol Renovation Plaster ensures long-term damp protection, resistance to salts, and a durable, high-quality finish.
