Self-levelling Compound
Application

Suitable for internal use in wet and dry areas when electric underfloor heating is laid beneath carpets, Karndean, vinyl or bonded engineered board floors. Will accept most other types of floor covering, including polyvinyl chloride (PVC), linoleum, ceramic tiles, parquet, and textile carpeting. It can be used in thicknesses of 5–50 mm in a single pour (12 mm thickness is required when used with underfloor heating).

The compound is compatible with:

  • Heating mats.
  • 3 mm heating cable.
  • FlexHeat cable.
  • 7 mm cable.
  • Thermal insulation boards.

Can be applied with hand tools or via a mixing pump. For chipboard and ply floors, any gaps must be sealed before application.

Surface finishing with floor paint can be used on areas with moderate traffic.

Not suitable for use outdoors or in water tanks and swimming pools.

Description

High quality, fibre-reinforced, flexible self-levelling compound, specifically designed for use with electric underfloor heating.

Features and benefits:

  • Provides a safe base to install the floor onto.
  • Can be used with almost any type of floor covering, once dried.
  • Works with underfloor heating to provide optimum heat spread, ensuring no hot or cold spots, and a fast warm up time.
  • Chemically dries and can be walked on in three hours, with further surface treatment possible from six hours after pouring.
  • The compound will naturally smooth the surface on to which it is applied.
  • The hardened mix has good moisture resistance characteristics.
  • A fall to a drain can be created if reduced water content is used.
  • Low dust formula.
  • CE marked.
  • Supplied in 20 kg bags.
