Description
RenderProof – BBA Approved Waterproofing & Plasticising Render Additive
RenderProof is a high-performance waterproofing and plasticising additive designed for cement renders used after the installation of a damp-proof course (DPC) or in other waterproofing applications. BBA-approved, it effectively blocks water penetration, while allowing walls to breathe and dry naturally.
By minimising liquid water movement through the pore structure of cement renders, RenderProof prevents salt transfer to the surface, protecting against efflorescence and damp-related deterioration.
Key Benefits:
✔ Prevents Water Passage – Reduces moisture penetration in render applications.
✔ Blocks Residual Ground Salts – Prevents salt migration, protecting surfaces from efflorescence.
✔ Vapour Permeable – Allows walls to breathe naturally, avoiding trapped moisture.
✔ Highly Concentrated Formula – Covers large areas efficiently with a single application.
✔ Easy to Use – Simply mix into cement render for seamless waterproofing.
✔ Ideal for External Renders – Designed for use after damp-proofing treatments such as Ultracure or Siliconate K.
✔ BBA Approved – Tested for long-lasting performance and reliability.
Ideal Applications:
✔ Replastering After Damp-Proof Course (DPC) Installation
✔ External Cement Renders
✔ Salt-Contaminated & Damp-Affected Walls
✔ Waterproofing Protection for New & Existing Structures
For best results, replastering should be carried out on surface-dry walls, with at least 14 days of drying time after DPC installation before applying RenderProof-enhanced render.
RenderProof ensures long-term waterproofing, breathability, and salt resistance, making it an essential additive for durable, moisture-protected cement renders.
