Mapei UC Leveller - Fast Hardening Levelling Compound

UCLEVELLER

Mapei UC Leveller is a fast hardening levelling and smoothing compound suitable for thicknesses ranging from 3 mm to 70 mm. It is specially recommended for pumping applications. This grey powder contains special fast-setting and hydrating cements, graded silica sand, resins, and additives, creating a fluid and self-levelling mix. UC Leveller is designed to level and smooth new or existing substrates before installing carpet, carpet tiles, ceramic tiles, natural stone, or floating timber flooring. It is ideal for areas requiring resistance to heavy loads and traffic, while delivering an especially smooth surface.

Technical Characteristics:

  • 20Kg
  • Fast hardening and hydrating formula
  • Excellent self-levelling properties
  • Cures rapidly and can be applied with an automatic pressure pump
  • Can withstand wheeled chair traffic
  • Minimal shrinkage for thicknesses up to 70 mm
  • Recommended addition of 30% of 3-5 mm aggregate for thicknesses above 40 mm
  • Provides excellent compressive and flexural strength, impact, and abrasion resistance

Recommended Use:

- Interior applications for thicknesses from 3 to 70 mm as a bulk-filling underlayment compound. - Suitable for smoothing concrete slabs, cement-based screeds, anhydrite screeds, and under-floor heating installations. - Can be applied over existing ceramic tile, terrazzo, natural stone, and magnesite floors. - Ideal for improving substrate conditions before flooring installation.

Installation:

Flooring can be installed once UC Leveller has dried, which typically takes 12 hours for light foot traffic and 24 hours before installing flooring at 23°C and 50% RH, depending on the thickness, temperature, and moisture in the environment.

Recommendations:

  • Do not add more water to the mix once it has begun to set.
  • Do not add lime, cement, or gypsum to the mix.
  • Not suitable for exterior use or substrates subject to rising damp.
  • Apply Eco Prim T Plus diluted with 2 parts water before adding another coat of UC Leveller over the completely dried previous one.
  • Do not use UC Leveller at temperatures below +5°C and above +35°C.
  • Follow all movement joints present in the substrate and form control joints on large areas to alleviate stress.

Cleaning:

Hands and tools can be cleaned with water while UC Leveller is still wet.

Consumption:

Approximately 1.6 kg/m² per mm of thickness.

Packaging:

Available in 20 kg bags.

Storage:

Store in the original sealed packaging for up to 12 months. Over longer periods, the product may set less rapidly without changing its final performance results. Store in a dry, elevated area, and protect from moisture.
