Quality factory produced bedding screed available from our nationwide plant network situated throughout mainland United Kingdom. Tarmac Trutile bedding screed contains a retarding admixture in order to remain workable for 8 – 12 hours.
Where can Trutile be used?
Trutile cement sand bedding screed can be used for the installation of floor tiles suitable for use on bases such as;
- Solid concrete ground floor slabs
- Precast concrete units or beams with reinforcement.
- In situ suspended floors.
- As a topping to lightweight screeds based on perlite or other lightweight aggregates.
- Certain other situations – refer to technical helpdesk
Ceramic floor tiles may be installed immediately using the Wet-bed or Wet-lay Method.
If floor tiles are to be installed using an adhesive, then it may be more appropriate to use an alternative Tarmac Screed product.

Additional info
Typical Drying Times
In typical Wet-bed or Wet-lay applications, then drying times will not be relevant.
However, for info and guidance, allow approximately one month per 25mm of thickness. Where the screed is above 50mm, any thickness above 50mm should be allowed to dry for two months per 25mm of thickness.
Where the concrete base has excessive moisture content these times should be increased. High humidity or low temperature will also delay the drying out process. As the drying times indicated apply from the completion of any curing operations, the flooring contractor must check the moisture content of the screed prior to laying the final floor finish
