Snowdrift Fixing Instructions


Fixing instructions for snowdrift onto suspended timber floor with electric wire underfloor heating

1 Ensure that Joists, floor boards, Waterproof ply, Tongue and grove etc are stable without excessive movement, screwed down, dust free and dry.

2 Cut Ditra matting to fit area then fix using Ditra Adhesive. Ensure sheets are overlapped and a kerdi matting skirting is used if the area is to be water proof.

3 Apply single part rapid flex white adhesive to the Ditra matting to create a level screed 2mm above the Ditra matting. Allow to dry

4 Fix the under floor heating as per manufacturers instructions & test. Ensure that none of the heating elements are in contact with matting.

5 Fix the Tiles with a minimum 2mm grout joint using a white rapid flexible adhesive, using a notched trowel to create a 4mm bed, using the solid bed method of fixing so that at least 90% of the tile is in contact with the adhesive and that the bed is free from voids. Snowdrift is a compressed quartz so the fitting instructions must be adhered to, to ensure the product will meet its performance targets. Also ensure that none of the heating elements are in contact with the tile. Allow to dry

6 Grout using a flexible floor grout

7 Clean and set up a regular maintenance programme.

8 Do not switch on the under floor heating on for at least 2 weeks and then only increase the temperature above room temperature by 2 degree increments per day until the desired temperature has been achieved.
