Our XPS Tile Backer Boards provide a strong, waterproof and thermally efficient base for tiling in wet rooms, bathrooms, shower areas and underfloor heating systems. Designed for both DIY and professional installers, these boards offer excellent moisture protection, high compressive strength and quick, easy installation.
Key Features
Waterproof & Moisture Resistant
Made from closed-cell extruded polystyrene (XPS), these backer boards prevent water absorption, mould growth and rot — ideal for high-moisture environments.
Strong Yet Lightweight
The reinforced cementitious coating delivers high strength and durability while keeping the boards lightweight and easy to handle.
Multiple Thickness Options
Choose from 6mm, 10mm, 12.5mm or 20mm depending on your installation needs. Use thinner panels for walls and thicker options for flooring or insulation upgrades.
Improved Thermal Insulation
Perfect for underfloor heating projects, the XPS core maintains heat efficiency and reduces heat loss through subfloors.
Easy to Cut & Install
Score, snap or cut with a utility knife for fast fitting. Suitable for tiles of all sizes and heavy load applications.

FAQ's
Q1: Can I tile directly onto this board?
Yes. The cement-coated surface provides an excellent key for tile adhesives.
Q2: Are these boards suitable for showers and wet rooms?
Absolutely. They are fully waterproof, rot-proof, and mould-resistant.
Q3: What thickness should I choose?
6mm: Wall linings and levelling surfaces
10–12.5mm: General-purpose use on walls and floors
20mm: Extra insulation or where higher strength is required
Q4: Do I need special tools to cut it?
No. You can simply score and snap with a knife or cut using a saw.
Q5: Can this be used with underfloor heating?
Yes. The XPS core provides thermal insulation and improves heating efficiency.
Q6: Can I install it over uneven surfaces?
Yes, but severe unevenness should be levelled first for best results.
Q7: Do the joints need sealing?
Yes — especially in wet areas. Use waterproof tape or mesh tape over all joints.
Installation Guide
Installation Guide
1. Prepare the Surface
- Ensure the surface is clean, dust-free, dry, and level.
- For floors, use a levelling compound if required.
2. Measure & Cut
- Mark the board where needed.
- Score and snap with a utility knife or cut using a saw.
- Boards can be shaped easily around pipes and fixtures.
3. Apply Adhesive
- Floors: Use flexible tile adhesive with a notched trowel.
- Walls: Apply adhesive and secure with screws and washers for additional support.
4. Fix the Boards
- Press boards firmly into the adhesive bed.
- Lay them edge-to-edge with tight joints.
- Stagger the boards where possible for added rigidity.
5. Seal All Joints
- Apply waterproof mesh tape or sealing tape over every joint.
- This step is crucial in bathrooms, showers, and wet-room areas.
6. Finish the Surface
The cement-coated surface is immediately ready for:
Tiling, plastering, rendering, underfloor heating, and installation.
