Installation recommendations for slate natural stone flooring
Ensure the sub-floor is sound and free from dust & grease etc.
Fix the slate tiles with an approved Rapid Set or Ordinary Set Adhesive.Use the thick bed method so that the tile is totally supported by the adhesive.If the slate is to be fixed to a wooden floor, or a floor with under-floor heating the appropriate adhesive must be used. Our recommendations would be Thick Bed, which is a one part flexible adhesive. For more unstable wooden floors we would recommend PCI Timberflex.
Keep the job clean at all times and immediately remove any excess adhesive from the tiles.
After the adhesive has set, clean the tiles with fresh water.
Once they are dry, apply the first coat of sealer. The sealer can be:
After sealing, grout using a wide joint grout either Grey, Sandstone or Limestone. If a flexible adhesive has been used the appropriate additive should be used in the grout, our recommendation is Dunlop Flexible Additive (one capful per bucket).
After grouting, ensure the slate is thoroughly clean and any excess grout has been completely removed with water (more stubborn grout can be removed with Deterdekor any proprietary cement remover), then apply the final coat of sealant, and if using Fila MP/90, apply two coats of Fila matt wax.
