V4 Alpine Plank Flooring - Forest Oak - 150mm

Before delivery and acclimatisation

• Use an experienced wood-floor fitter and complete all wet trades before delivery.
• Maintain approximately 18–24°C and 45–65% relative humidity before, during and after fitting.
• Store engineered boards sealed and flat in the fitting room for at least three days; solid boards require at least seven days.

Subfloor preparation and moisture

• The subfloor must be sound, clean, dry and free of paint, plaster, oil, dust and movement.
• Check flatness with a 2 m straightedge. Variation must not exceed 3 mm; level high or low areas before fitting.
• Measure and record subfloor moisture with the correct calibrated meter. Apply a compatible surface damp-proof membrane where readings or construction require it.
• Secure loose timber subfloors, countersink fixings and overlay uneven boards with suitable flooring-grade plywood without aligning joints.
• For full bonding, mineral subfloors must be below 65% RH; timber subfloors should not exceed 11% and should be within 2% of the flooring.

For more detail, read our engineered-floor subfloor preparation guide.

For boarded or suspended bases, read our timber subfloor preparation guide.

Fitting this floor

• Required method for this product: Fully bond or float; 18–20 mm planks may also be secret-nailed to a suitable timber subfloor.
• For a floated tongue-and-groove floor, use the correct underlay and a continuous bead of D3 joint adhesive in both long and end grooves; do not spot-glue joints.
• For a bonded floor, use a compatible permanently flexible wood-floor adhesive and the specified notched trowel, checking adhesive transfer as work proceeds.
• Lay from at least three packs, inspect every board in good light and reject visible defects before fixing.
• Stagger end joints by at least 200 mm and avoid a repeating brick-bond pattern.

Use a system appropriate to the site and read our wood-floor adhesive guide.

Expansion, inspection and completion

• Provide at least a 15 mm perimeter gap (or the larger manufacturer-calculated allowance) at walls, door frames, pipes, hearths and fixed obstructions.
• Use movement breaks between rooms and wherever the manufacturer’s maximum uninterrupted span would be exceeded.
• Allow for cutting waste, grading and natural variation; mix boards across packs before fixing.
• Stop and contact Wiltshire Wood Flooring Supplies before fitting if the product, subfloor, site readings or proposed method do not match these requirements.
