Step One:
Floor preparation

Styrofloor can be laid on existing or new floors. On existing floors, ensure that the skirting is removed and where necessary level use a proprietary levelling compound. New concrete floors should be left as long as possible before laying Styrofloor to allow adequate time to dry out. Providing that the new floor is level, the use of a floor screed in not essential.

Step Two:
Damp proofing

The incorporation of a damp proof membrane should be in accordance with established building practices (see BS8102). In the absence of a damp proof membrane, a 1000 gauge polythene sheet can be used prior to laying the Styrofloor. Where continuous flexible sheet (e.g. PVC) is used, it should be turned up at the wall abutments.

Step Three:
Setting out

Ensure that all subsequent boards are positioned so that cross-joints are staggered to produce a brick pattern. All joints should be bonded using water resistant PVA adhesive. When laying adjoining boards, ensure that the tongue and groove joints are engaged and then tap each board with a suitable block to ensure it is tight-up against the adjoining board.

Step Four:
Laying your floor

The Styrofloor boards should be laid with a 10-12mm expansion gap at all abutments, between walls and the chipboard.

All joints should be bonded using Water Resistant PVA Adhesive, to obtain the best results, allow the adhesive 24 hours in which to harden.

Wedges/spacers can be used between the wall and edge of the Styrofloor to help press tongue and groove detail together while the glue hardens.

Step Five:
Finishing up

To obtain the best results, allow the adhesive 24 hours in which to harden before removing wedges. Check that expansion gaps are clear prior to the fixing of skirting boards. Should there be any unevenness, Styrofloor can be sanded down to the required level.

The final floor finish can now be laid directly onto Styrofloor. Carpet, laminate or tiles can be used onto the chipboard which provides a sturdy and long lasting finish.
