Self Levelling Compounds

Self levelling compound, also known as floor screed or floor levelling compound, is used to create a smooth, even surface before laying tiles or other flooring. Without it, any dips or raised areas in your existing subfloor can cause tiles to rock, crack, or lift over time, so applying a self levelling compound first is an important step in achieving a long-lasting, professional finish.

Yes, flexible self levelling compounds in our range are specifically designed to be used over underfloor heating systems. The flexibility allows the compound to accommodate the slight expansion and contraction that occurs as the heating system warms and cools, preventing cracking in the finished floor surface.

Flexible self levelling compounds in our range are compatible with timber floors including plywood subfloors. Standard rigid compounds are not recommended for timber because timber naturally moves with changes in temperature and humidity, so always check the product specification to ensure you are selecting a flexible option if your subfloor is timber-based.

Our self levelling compounds can be applied at a range of depths, from a feather edge finish for very minor imperfections right up to depths of 50mm for more significantly uneven substrates. This makes them suitable for anything from a light skim to fill small low spots to a full deep pour to correct a badly uneven floor.

Drying times vary between products, but most self levelling compounds are ready to tile over within a few hours under normal conditions, though some may require up to 24 hours before heavy foot traffic or tiling commences. Always check the specific drying time listed on your chosen product page, and ensure the area is well ventilated to help the compound cure properly.
