Best cut using circular saw with dust extraction fitted. Can also be cut using a jigsaw or hand saw fixed with a heavy duty blade.
Maxiboard must be laid flat and kept dry. Maxiboard should only be stored on site if the building has been sealed and is completely dry.
Finishing & Plastering:
We recommend that plasterboard board be fitted over the Maxiboard and finished according to manufacturer’s instructions.
However, should you need to plaster directly onto the Maxiboard, we advise skimming the 10mm lighter coloured, gypsum board side of the Maxiboard. Prior to skimming, all Maxiboard joints should be filled with proprietary joint filler and taped, using paper tape, applied with undiluted plastering PVA. The whole surface should then be bonded with PVA, diluted according to the manufacturer's recommendations. A skim coat of multi-finish may then be applied. Unfortunately, SRS cannot be held responsible for the quality of any plaster finish applied directly onto Maxiboard.
It is essential that the Maxiboard is free from moisture before plastering to avoid the risk of cracking at the joints. Factors such as product storage prior to installation and site conditions must be assessed before applying the skim. Should the plastering contractor suspect moisture in the Maxiboard, they should wait until the boards are fully conditioned on site.
