Moisture exposure limits
As a P5 MR grade board, this product is suitable for areas with moderate moisture exposure typical of living spaces, bedrooms, and hallways. It is not appropriate for kitchens with high steam exposure, bathrooms, or any area subject to standing water or prolonged dampness. For wet rooms, specify a marine-grade or cement-bonded board instead.

Subfloor and joist preparation
The subfloor must be dry, level, and structurally sound before laying. Timber joists should be spaced at maximum 400mm centres to support the 22mm thickness adequately. Check that joists are not deflecting under load and that any existing flooring is removed. Ensure adequate ventilation beneath the floor to prevent moisture accumulation.

Installation and finishing
Lay boards with the tongue and groove profile engaged, staggering joints across joists for maximum strength. Once fixed, the floor is ready for finishing materials. Sand lightly if required before applying adhesive for vinyl or carpet. The stable, high-density construction minimises movement and squeaking once properly installed.
