What is the most critical step before laying PVC flooring?

Preparing a smooth, clean, dry, and structurally sound sub-floor is the most critical prerequisite (Clause 3).

What is the minimum recommended temperature for installation?

The area's temperature should be maintained at not less than 18°C before, during, and for 24 hours after the installation (Clause 5.1).

How soon can the newly laid PVC floor be used?

The floor should not be subjected to traffic for at least 24 hours after laying, and washing should be avoided for at least 72 hours (Clause 5.5).

Does the sub-floor need to be completely dry?

Yes, the sub-floor must be thoroughly dry. A moisture check using a reliable moisture meter is recommended before proceeding (Clause 3.2.3).

Practical Notes

Sub-floor preparation is the most critical factor; any dampness, dust, or unevenness in the base will severely affect the final finish and longevity of the flooring.

Always allow both the PVC flooring material and the adhesive to acclimatize to the room's temperature and humidity for at least 24 hours before starting work to prevent future dimensional changes like shrinkage or expansion.

Use the specific notched trowel size recommended by the adhesive manufacturer to achieve the correct adhesive coverage and ensure a strong, uniform bond.
