Maxideck - Installation Guide

NOTE: SRS Ltd advise that for best results Maxideck is installed above a ceiling comprising two layers of plasterboard on resilient bars, with 100mm dense mineral fibre between the joists. The direct fix result is given as information only, for those people who already have a ceiling in place. If you must install Maxideck above an existing ceiling, it may need upgrading. SRS suggest 2 layers of plasterboard, with a minimum mass per square metre of 20kg/m2, and 100mm of dense mineral fibre in the cavity, as a minimum requirement.

Maxideck installed onto a timber floor

The existing floor surface should be dry and free from debris before installing the Maxideck. If the existing floorboards have gaps between them, they must be filled with a flexible sealant. The Maxideck is fitted in a brick bond pattern, with the felt facing down.

Where the Maxideck meets the skirting boards at the perimeter walls, the overlap on the top board of the Maxideck should be removed. In order to isolate the boards from the skirting, and allow for any expansion that might occur, the self adhesive 25mm 5/26 Maxideck Edging Strip should be applied directly to the trimmed edge of the board. This enables the installer to locate the boards easily, leaving a 10mm expansion gap, which the Soundseal will expand to fill. Please note that the rate of expansion varies depending on site conditions - a period of 24hrs should be allowed for full expansion.

If fitting skirting boards after the Maxideck has been installed, you must use the wider 32mm 5/26 Maxideck Edging Strip on the boards that meet the perimeter walls. The excess Edging Strip expands over the top of the Maxideck and provides the installer with a resilient base to sit the skirting on.

Once fully installed, the Maxideck can be treated as a standard timber floor finish, however, please refer to manufacturers instructions before installing any decorative floor finish.

All Maxideck joints are to be glued with SRS Gripfix. Joints are then screw fixed using 20 x 3.5mm, countersinking screws. Two screws are recommended along each long edge of the individual boards, 100mm either side of the joint in the previous row. The SRS Gripfix will achieve full bond strength after 24 hours cure. It is essential that screw fixings do not penetrate the felt layer – no screws longer than 20mm should be used.

Should you need to cut a hole in the Maxideck to accommodate any pipework, you should use the correct sized hole saw to remove the section of Maxideck. Another section of Maxideck, from the hole to the edge of the board, should be then be removed using a hand saw or jigsaw to allow the service/pipe to be located in the board – this piece should be retained. Once the pipe is in place, the retained section can be glued back into position using SRS Gripfix. SRS Acoustic sealant can be used to fill any gap between the pipe and the Maxideck.

General Installation Notes

There are a vast number of floor finishes available, and, as such, the installation guidance shown is given in good faith and to the best of our knowledge. The final decision regarding the compatibility of any floor finish installed onto Maxideck must remain the responsibility of the flooring contractor / installer. If in any doubt, please seek advice from the floor finish manufacturer.
