Many absorbent and non-absorbent substrates require a compatible primer to control suction and improve the bond. Use the primer and dilution stated for the exact leveller and substrate.
Cement Based Leveller Before Tiles and Floor Coverings
Self levelling compound creates a smooth, even surface before tiles, vinyl, laminate or other floor coverings are installed. MacBlair stocks cement-based levellers for approved interior substrates, with application depth, drying time and covering compatibility set by each product. It flows readily, but still needs controlled spreading and level checks.
Preparation drives the result. Remove dust, grease, loose material and laitance, repair movement or cracks as required, and apply the stated primer. Compare related building and floor preparation materials before mixing so every bag can be poured within its working time.
Measure the room and average depth to estimate coverage, allowing more material where the floor varies. Adjacent work involving timber and sheet-based construction or floor insulation materials must be stable and compatible with the chosen levelling system.
Self Levelling Compound FAQ's
Only use it on plywood, chipboard or other timber substrates when the product data sheet explicitly allows that construction. The floor must be rigid, securely fixed and prepared with the specified primer or reinforcing system.
Permitted thickness varies widely between products, and some have different limits for one pour or with added aggregate. Measure the deepest area and choose a leveller whose stated application range covers it.
Drying time depends on product, thickness, substrate, temperature and humidity. Use the manufacturer’s covering time as a guide and meet any moisture requirement for the final floor finish.
No. Levelling compound is generally used in thinner layers to smooth a prepared subfloor before a covering. Screed forms a thicker floor layer or falls and has different installation, curing and structural requirements.
