FERMACELL flooring boards are easy to install, side by side, one after the other. The only precautionary measure to be taken: be sure the existing sub-floor is clean, dry and structurally sound.

The flooring boards are assembled using glue, followed by a process that uses screws or staples to apply pressure as the boards are set into place. The two-step process guarantees perfect adhesion. This type of interlocking system is not only simple to install, but can also support a heavy weight load, even at the joints and seams between boards.

Steps for a secure Installation

Lay a strip (foam or mineral wool) all along the foot of the wall to help keep sound from permeating sideways.

On the first row of boards, an adjustment will be necessary to guarantee uniform resistance: cut the two upper joints (big and small) from the first board, then the big joint from the subsequent boards.

Lay the first board. Having already cut the two upper joints allows for direct application in the corners, between walls. Continue to lay the boards following the instructions in the installation guide.

Apply two lines of FERMACELL floor glue (yields 25 to 30m2 per bottle) to each of the lower lap joints. Follow the detailed instructions on the packaging.

Next, fasten the joints, one on top of the other, to ensure proper pressure is applied for the glue to bond. The screws can be replaced by special staples, which can be quicker to use.

After drying, remove any excess hardened glue from the joints and seams, and level the surface using FERMACELL joint filler.
