TECCA Tile Backer Boards provide a high-performance, cost-effective solution for preparing walls and floors for tiling. Designed to replace traditional materials such as plasterboard and plywood, these boards create a stable, waterproof, and insulated surface suitable for all types of tiling projects.
Lightweight, durable, and easy to cut, they can be installed over a wide range of substrates including concrete, timber, masonry, brick, and metal. When all joints and corners are sealed with waterproof tape, the system forms a fully water-resistant surface ideal for showers, wet rooms, and other moisture-sensitive areas.
Enhanced thermal properties help improve underfloor heating efficiency by up to 50%, making these boards an excellent choice for both professional installers and DIY users.

Installation Instructions
Mark 8–15 fixing points on each board.
Apply flexible tile adhesive at each point and press the board into place.
Once set, drill through the fixing points into the solid substrate.
Fix using screws and washers — tighten until just flush (do not overtighten).
Tape all board joints using glass fibre tape; use waterproof tape for wet areas.
