Sika® Ucrete® UL

(former Ucrete® UL)

Heavy-duty, cementitious, underlayment screed for Sika® Ucrete® flooring systems

Sika® Ucrete® UL is a one-part, fast-curing, shrinkage compensated underlayment screed for use beneath Sika® Ucrete® flooring systems. It is a ready-to-use material that contains special hydraulic binders, well-graded sands and specifically selected polymers. Depending on the mixing water addition, the consistency of the mortar can be adjusted to provide a thixotropic material for application to falls or a fluid material for levelling or pumping.

  • Fast curing and fast strength-development at low temperature allows for early preparation and application of Sika® Ucrete® flooring after 16 hours at +10 °C
  • Very good resistance to thermal shock when used as part of a Sika® Ucrete® flooring system
  • Very good workability and finishing in all consistencies
  • Easy to apply and lay as a monolithic flat floor finish or on a slope
  • Low shrinkage, reducing stress on the substrate and reducing the risk of cracking
  • Pre-batched, one-part mortar that only needs the addition of water
  • Suitable for internal or external application, on all horizontal surfaces, in dry and wet environments
  • Layer thickness of 10–100 mm
