Alnwick Oak Chevron Flooring - 120mm

Before delivery and acclimatisation

• Use a trained wood-floor fitter and complete all wet trades before delivery.
• Maintain approximately 18–20°C and 50–65% relative humidity; for planks wider than 175 mm do not exceed 60% RH.
• Keep sealed packs flat and supported in the fitting room; only open each pack immediately before use.

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.
• Brooks specifies approximately 12–14% moisture for timber subfloors and 3.5% moisture content, or 35–40% RH by slab test, for cementitious subfloors.

Fitting this floor

• Dry-lay and mark accurate centre and control lines before applying adhesive; check the pattern remains square throughout the room.
• Spread only as much flexible wood-floor adhesive as can be covered within its open time, using the manufacturer’s specified notched trowel.
• Press every block or board into a continuous adhesive bed and confirm full adhesive transfer. Patterned floors must not be floated.
• Keep the first rows aligned while the adhesive grabs, then re-check measurements frequently to prevent the pattern stepping.
• Clean adhesive from the face immediately with the approved cleaner and allow the full curing time before traffic or furniture.

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.
