Our Subfloor Preparation Collection
A reliable subfloor starts with the right primer and damp protection. Our Marldon MXS150 Rapid MVS Primer, MXS120 Universal Subfloor Primer and MXS170 Textured Primer create a strong, durable base for every floor type, including floor primer for concrete and screed. Where moisture is a concern, the Marldon MXS140 Rapid DPM gives fast-acting damp-proof protection, and our M1-F Bitumen Paper adds an extra subfloor dpm membrane for rising damp.
For a smooth, even base, our subfloor smoothing compounds, led by the Marldon MXS110 Smoothing Compound, offer a quick drying self levelling compound developed specifically for wood flooring, giving fast turnaround without compromising on finish.
Before you start, test subfloor evenness, cleanliness and moisture with calibrated meters, and prime concrete or screed surfaces to seal and promote adhesion. Match products correctly to your substrate and final finish, mix levelling compounds to the specified consistency, and allow full cure times before proceeding with adhesives and finishes.
Our subfloor preparation products are trusted by flooring professionals across the UK, backed by technical support for DPM membranes and other specialist solutions, with fast, reliable delivery to keep your project on schedule.
