Installation recommendations for unfilled travertine natural stone flooring

  1. Ensure the sub-floor is sound and free from dust & grease etc.
  2. Fix the travertine 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 travertine 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.
  3. Keep the job clean at all times and immediately remove any excess adhesive from the tiles.
  4. After the adhesive has set, clean the travertine tiles with fresh water.
  5. Once they are dry, apply the first coat of sealer. The sealer can be:
    • matt finish – Stainstop or MP90
  6. After sealing, slurry grout using a wet mix of wide joint grout: either 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 (2 – 3 capfuls per bucket).
  7. After grouting, ensure the travertine is thoroughly clean and any excess grout has been completely removed with water, then apply the final coat of sealant and two coats of liquid wax.

Slurry grouting

To slurry grout, mix the grout so that it is quite wet and, using the grout float, spread the grout over the entire surface of the travertine, ensuring that the grout is pressed into the holes in the surface as well as between the tiles. 

Wipe excess grout off the surface with a damp cloth before the grout is completely dry.
