Plaster Mesh Tape – Butyl-Backed for Sealing Meshed Membranes. Biokil Crown Plaster Mesh Tape Black is a specialist single-sided sealing tape designed for use with meshed damp-proofing membrane systems. It features a robust butyl adhesive backing and a mesh-faced upper surface that acts as a secure key for plasters and renders.. This tape is primarily used to seal and reinforce joints between adjacent sections of meshed membranes in above-ground waterproofing and damp-proofing applications. It is also ideal for covering damaged areas or failed fixing points, maintaining the integrity of the membrane layer while still allowing for finishing coats.. Key Features & Benefits. Mesh-Faced Surface: Provides a reliable plaster/render key for finishing layers.. Waterproof Butyl Adhesive: Ensures strong adhesion and seals against moisture ingress.. Multi-Purpose Repair: Use for covering membrane joints, sealing around fixings, or patching minor damage.. Flexible & Easy to Apply: Conforms to membrane surfaces and cuts easily to size.. Typical Applications. Sealing butted joints in meshed cavity drainage or damp-proofing membranes. Creating a continuous plasterable surface across joins and overlaps. Covering fixing points where plugs may have failed to grip. Repairing minor surface damage in meshed membranes. Installation Guidance. Ensure the membrane surface is clean, dry, and free from dust or oil.. Cut the tape to the required length using scissors or a utility knife.. Peel back the protective liner to expose the butyl adhesive.. Press the tape firmly over the joint or damaged area, mesh side facing outwards.. Proceed with plastering directly onto the mesh face once fully adhered.
