Floor Levelling Compound


Floor levelling compound used for preparing sound subfloors ready for the installation of new floor coverings.

Covers both absorbent and non-absorbent surfaces such as old adhesive residues, asphalt, terrazzo, epoxy, polyester resins, ceramic and some waterproof surface membranes.

Suitable for biologically sensitive areas and is easy to mix and apply. Where added adhesion, strength or flexibility is required, Sovereign Latex Polymer Additive is highly recommended. Surfaces must be primed with Sovereign Neoprene Primer.

Floor levelling compound should be sufficiently hard to walk on in about four hours under good conditions.

Use in conjunction with Sovereign Neoprene Primer.
