Is My Floor Suitable For Tiling?

16th September 2019


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.
