Extended Product Information
FAQs
Are these boards suitable for a steam shower?
While these boards are waterproof and excellent for wet areas, for steam showers, it is crucial to implement a comprehensive waterproofing system over the boards, including sealed joints and membrane application, to ensure full steam resistance.
Can I tile directly onto these boards?
Yes, these boards are designed as a substrate for tiling. Ensure you use a suitable tile adhesive that is compatible with XPS boards.
What is the coverage of one pack?
One pack contains 5 boards, each measuring 600x1200mm, covering approximately 3.6 square metres.
How thick are the boards?
These specific boards are 12mm thick.
Can I use these boards on an external wall?
These boards are designed for internal wet areas like bathrooms and kitchens. For external applications, consult specific building codes and suitable weather-resistant materials.
Do I need special tools to cut them?
No, standard tools like a sharp utility knife or a handsaw are sufficient for cutting these boards. For very precise or repeated cuts, a track saw or jigsaw can also be used.
What is the compression strength?
The compression strength is 35 tonnes per square metre (35t per m²), providing a very stable base for tiling.
Troubleshooting
Board is difficult to cut.
Ensure you are using a sharp utility knife or a fine-toothed saw. Score deeply and repeatedly for cleaner cuts.
Tiles are not adhering well to the board.
Verify that the correct type of tile adhesive is being used, that the board surface is clean and free from dust, and that the adhesive has been applied evenly with full coverage.
Uneven surface after installation.
Ensure the subfloor is level before installation. Check that adhesive has been applied uniformly and that boards are pressed firmly into place. Use a levelling compound if necessary before tiling.
Waterproofing is compromised.
Ensure all joints are properly sealed with tape and adhesive, and that any penetrations (e.g., around pipes) are meticulously waterproofed using appropriate sealants and tapes.
Pros and Cons
Pros
Excellent waterproof properties for wet areas.
Provides a stable and rigid substrate for reliable tile adhesion.
Easy to cut and handle, simplifying installation.
Compatible with underfloor heating systems.
Good thermal insulation properties.
Cons
12mm thickness may require adjustments for flush finishes in some settings.
Requires specific adhesives and grouts for optimal performance.
Not suitable for extreme structural load-bearing applications without additional support.
Best suited for medium-sized projects; larger areas may require more boards or different solutions.
Setup, Compatibility & Care
Setup:
Ensure the subfloor or wall substrate is clean, dry, and structurally sound.
Cut the boards to size using a sharp utility knife or handsaw. The blue foam edges can help guide cuts for a cleaner finish.
Apply a suitable tile adhesive to the substrate or the back of the board according to the adhesive manufacturer's instructions.
Press the backer board firmly into the adhesive, ensuring full contact and a level surface. Use mechanical fixings if recommended by the adhesive manufacturer or for specific applications.
For adjacent boards, ensure they are butted tightly together or use joint tape and adhesive as per best practice for tile backer boards.
Compatibility:
Compatible with all standard tile adhesives and grouts.
Suitable for use with underfloor heating systems.
Can be installed on concrete, timber, or existing tiled surfaces (check specific adhesive guidelines).
Care:
Boards are inherently waterproof, but finished tiled surfaces should be cleaned with mild, non-abrasive cleaners.
Avoid harsh chemicals that could damage grout or sealant.
