Cemfloor Liquid Screed RTU

Application

Designed for use as a bonded thick levelling screed on concrete, as a floating screed over thermal or acoustic insulation with a minimum compressive strength of 100 kPa, or as an unbonded screed on top of a plastic membrane.

Description

A self-levelling cementitious floor screed that complies with EN 13813 and can be applied to a wide range of floors. Therm RTU is a mixture of Cemfloor binder, cement, water and a kiln-dried sand. Therm RTU is available in 25 kg and 1000 kg bags.


Features and benefits:

  • Thinner sections compared to traditional screeds.
  • Larger floor area without joints.
  • Excellent thermal conductivity.
  • Reduced drying times (depending on drying conditions).
  • Self-compacting – no voids around underfloor heating pipes.
  • Can be applied in wet areas.
  • No risk of contamination at concrete mixing plants.
  • No surface laitance (dust) after curing.
  • Easy installation (reduces time and costs).
  • Floor flatness: SR2 (minimum).
  • Foot traffic after 24–48 hours.
  • In-situ crushing resistance (ISCR) test: Category A.
