When preparing to lay a new floor, it’s important that you make sure the surface underneath is level to ensure that defects don’t show through onto your new flooring and cause uneven wearing. Hardboard sheets are a great way to level a wood boarded floor, and as an added bonus this should reduce any draughts coming from below the house.
Choose 3mm thick hardboard sheets to level your floor, and make sure they are properly conditioned first by spraying water over the textured side and stacking them on the floor of the room for 48 hours - this means they’ll expand a little before drying and tightening which saves them from expanding and buckling after you’ve laid them.
If there are any wooden floorboards that stick out more than the others, plane these before laying your hardboard sheets.
Fix your hardboard sheets in place with short nails so that they don’t go through your floorboards and cause any accidental damage. Once you’re ready, follow our simple steps to laying your hardboard sheets.
Lay the hardboard sheets texture side up so you can see where the adhesive should lie. Start in one corner of the room and make sure that you set the nails around 13mm in from the edges of the sheet. Try positioning the nails in a pyramid pattern to prevent the sheets from buckling as you nail them down.
Make sure that the hardboard sheets are laid as close together as possible, nailing along each meeting edge before continuing in a pyramid fashion. Once you reach the end of the row, cut the last one to size.
Start the new row with the off-cut from the last row of sheets to prevent waste and ensure that the joints are staggered. Continue until the floor is covered.
