Gypsol TS-20; a multi-purpose thin screeding solution

Because of its particular formulation, you can lay our TS-15 screed either bonded or unbonded over a polythene slip membrane. You can use the product in both commercial and domestic construction projects.

Our customers use this screed to produce a smooth, flat and level floor to form the sub-base for subsequent floor coverings for internal floors. Constructions where you typically find these screeds are:

  • Houses
  • apartment schemes
  • schools
  • hospitals
  • offices
  • shops

Our customers are specially trained screeders that use specialised equipment to place the screed. Using our Gypsol TS-20 offers you a very cost-effective method of levelling an existing floor slab. Notably, because the product has very high strength and high resistance to cracking. As all other Gypsol screeds TS-20 is a highly environmentally friendly alternative to cement-based screeds. You can, therefore, use this as a heat transfer medium for thin section underfloor heating systems, whether electric or warm water.

Extensive Gypsol range

Every project might require a different type of screed. We have, therefore developed a full range of screeds that will suit every situation.

You can read more in detail on the particular product pages about these products.

  1. Rapide; A self-compacting, self-smoothing, fast-drying floor screed
  2. Classic; Our general-purpose screeding system. The most commonly used material in our range.
  3. HTC; Gypsol HTC (High Thermal Conductivity) for use with underfloor heating and cooling systems.
  4. TS-15; An ultra-thin screed for bonded and un-bonded applications at a minimum depth of 15mm.
  5. XS; Extra strength material for use in heavy-duty applications, where loading is likely to be higher than normal.
  6. TimBRE; Specially formulated and tested for use in timber frame and over timber supported floors including acoustic conditions.
  7. Sureflo; Pre-blended product supplied in 25kg bags for mixing on site. Ideal where minimal quantities are required, or access for ready-mix lorries is not possible.
  8. Summit; Particularly fit for screeds pumped over very long distances or high buildings of 10 stories and above.
  9. Modular; Designed for use in modular construction to allow early movement of units, also for a lightweight steel frame and Lewis Decking.
  10. Rustique; a unique fast track floor, providing a rustic or architectural finish.
  11. Diamond; a unique and innovative “micro concrete” providing a polished floor.

Gypsol TS-20 - Frequently Asked Questions

  • What is the minimal Gypsol TS-20 screed thickness my floor needs?


    Gypsol TS-20 screed can be used to the following minimum depths

    • 20mm Unbonded
    • 20mm Bonded
  • How soon can I lay my floor coverings on the TS-20 screed?


    Our Gypsol TS-20 screed dries naturally in around 20 days in right drying conditions based on 20mm depth. This screed dries by evaporation of residual moisture into the air above it. It is therefore important to ensure you dry in well-ventilated conditions to remove the moisture as it evaporates. On top of this, you should provide an appropriate moisture test to confirm the screed is suitably dried before applying floor coverings.
