Face Screwing: The traditional method. Simply screw through the face of the board into your sub-frame. Always Pilot Drill before fitting screws and drill 2mm oversize holes. We recommend 400mm centre to centre joist spacing. Each hole can be plugged. Deckwise Hidden Fastenings:allow you to lay your decking boards without the need for unsightly face screws. Each Deckwise clip screws into your sub-frame and then slots into the side of adjoining boards. We can pre-groove your decking boards for use with Deckwise clips or you have the option of using a biscuit jointer on site.
Whilst Cumaru decking is a very stable hardwood, we recommend that you leave a 3-5mm spacing in between each board. Being a natural product there will be some expansion and shrinkage depending on climate. Please note that as hardwood specialists, we do not stock softwood for sub-frames. We recommend that your source this from a standard timber merchants. We recommend sealing the cut ends of your boards with an end grain sealer.
We recommend installing your decking boards with the hardwood decking wrench. This is a self-locking deck board straightening tool that can be used to hold bent boards straight whilst fasteners are installed. See associated products below. We also offer a hire service.
