What is the most critical check before laying rubber flooring on a concrete slab?

Checking for dampness. The concrete sub-floor must be completely dry and fully cured (typically at least 28 days) to prevent adhesive failure.

How long should rubber tiles be conditioned before installation?

They should be unpacked and kept in the room of installation for at least 24 hours to acclimatize to the ambient temperature and humidity.

How should entrapped air be removed during laying?

By firmly rolling the surface with a suitable floor roller immediately after the flooring is placed onto the adhesive.

Practical Notes

Moisture in the sub-floor is the most common cause of rubber flooring failure (blistering or peeling); always ensure the concrete base is entirely dry before applying adhesive.

Rubber sheets or tiles must be unpacked and allowed to acclimatize to the room temperature for at least 24 hours prior to laying to prevent post-installation shrinkage or expansion.

Rolling the newly laid floor with a heavy floor roller is critical to expel entrapped air bubbles and ensure 100% contact with the adhesive bed.
