What is solid bed fixing and when is it required?

Solid bed fixing means achieving 100% coverage of the adhesive on the back of the tile. It’s required by British Standards for:

• All floor tiling
• Wall tiling with tiles larger than 0.1m² (roughly 300mm x 300mm)
• All tiling in wet areas, outside or in swimming pools

To achieve solid bed fixing with Dunlop adhesives:

1. Use the correct size notched trowel
2. For floor tiling, use a solid-bed trowel or a suitably sized notched trowel
3. Back-butter large format tiles
4. Periodically check coverage by lifting a newly laid tile
