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
