Care and installation instruction 
for oiled wood floors

Important note: Do not open flooring packages until ready to begin installation. Leave them unopened in the room for at least 24 h hours to acclimatize. Check all planks for defects before installation. Please notify us or your specialist dealer of any defects before installation! Defective goods may not be installed! Room climate: All wood products need a room climate with a relative humidity of 40–60% at a room temperature of 20–22°C to maintain dimensional stability. Make sure that the room climate does not exceed or fall below these values for prolonged periods of time.

Subfloor/screed:  The floor should preferably be installed a cement screed surface of grade ZE 30 or higher. For cement screed, the dampness of the screed may not exceed 1.8 CM% at the time of installation (for calcium sulfate screed, 0.3 
CM%). To guarantee that the screed is ready for installation in terms of its residual moisture content, it should be heated appropriately and professionally, no earlier than 28 days after application of the cement screed (heating protocol). HAIN floors can be laid over all stable subfloors (screed, old wooden floors, chip boards, etc.). The subfloor must be dry and even. Unevenness of more than 2 mm can be levelled with a suitable filling compound. 
For floating installation: an intermediate layer of cork or non-woven fabric reduces the acoustic impact. To avoid condensation build-up from residual moisture, use a plastic film as a vapour barrier. Make sure that the edges of the film extend high enough on the walls.

Underfloor heating: Temperatures of max. 40°C inlet temperature and max. 29°C surface temperature may not be exceeded under any circumstances. A signed heating protocol must be provided. 

Generally, full-surface bonding is recommended for all HAIN wood floors. For installation on underfloor heating, and for installation of floors with an 11 mm thickness and/or a laying width or length of more than 10 m, gluing down is mandatory. For floating installation of 15 mm floors in rooms more than 10 m long/wide, an expansion joint must be planned into the installation.

HAIN flooring can also be glued with all solvent-free adhesives (EC1 standard, e.g. Hain Elastic with a B13 spreader or HAIN elastic shear-resistant glue with a B15 spreader). More glue will be needed for long boards using hard elastic glue. To level out unevenness of the subfloor, you should use a filling compound that is suitable for parquet installations. To avoid head-lateral joints, we recommend the additional gluing of the head joints (H-joint gluing) with wood glue.

Tip: Fixed installation: Apply the adhesive with a spreader for max. two rows. Remove excess adhesive from surface immediately with a damp cloth.

Apply the glue to the entire surface of the inner, upper side of the groove to ensure an extra tight joint, and lay the planks 
immediately. Any pushed-up glue must be removed from the surface immediately with a damp cloth. When laying the first row, the grooved side of the plank faces the wall, while keeping a minimum distance of approx. 15 mm from the wall. Wedges, offset every 50 cm, will help you to keep the correct distance. The second plank should be placed lengthwise to the first, and the two planks glued together. The last plank of the row is shortened so that the wall distance amounts to approx. 15 mm. Use the remaining piece of the first row as the first plank of the second row. Make sure that the face ends are offset from each other by at least 40 cm. Hammer the newly placed plank in place at the face end by gently tapping on the opposite end (if necessary). The long sides are only hammered together after the face ends fit perfectly. Please only tap on the tongue side of the planks with the help of a crow bar. Direct the hammering of the long sides towards the face end, to increase the pressure on the face joints. The next row begins with the end piece of the previous row, and so on. At the end of each row, saw the wood to maintain a distance of 15 cm. Use an extra plank to mark the width. The last plank should be cut to the shape of the wall, while the long side should maintain a distance of at least 15 mm. After gluing, press the planks together using a crowbar.

Make sure that cutouts for heaters, etc. are large enough so that pipes and floor are not strained. Drill a hole, then saw the contours of the cutout. The remaining space may be covered by using a pipe collar.
