Is your subfloor/substrate suitable?

The suitability of a subfloor/substrate should always be fully assessed before carrying out any preparation or installing a floor covering. British Standard 8204 should be referred to for full guidance and clarification.

The main criteria to be assessed is:

  1. Sound/solid – is the subfloor/substrate strong and stable?
  2. Dry – has the subfloor/substrate dried/cured completely?
  3. Free from contamination – is the subfloor/substrate clean?
  4. Laitance free – is the subfloor/substrate surface free of fines?

If the answer to any of these is ‘no’, then the subfloor/substrate is not suitable to be laid onto and further preparation is required.
