Sika® Ucrete® UL - Fast-Curing Underlayment Screed
Verified by manufacturer 2 days ago
A one-part, fast-curing, shrinkage compensated underlayment screed for use beneath Sika® Ucrete® flooring systems.
Application
For use as an underlayment screed for Sika® Ucrete® flooring systems.
Suitable for internal or external application, on all horizontal surfaces, in dry and wet environments.
Description
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.
Features and benefits:
- 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.
