Colour Variation
Cumaru is renowned for its outstanding colouration. Whilst boards tend to range from light brown through to dark honey, sparks of orange and dark golden brown can also feature. When the different shades are fitted together, an impressive, contemporary, rich, dark and unique deck is achieved. This colour variation is widely sought after. Cumaru like many other species can be prone to worm hole and Raised Grain which are natural defects and acceptable within grading. If, however, you are you are looking for a more uniform finish, we recommend one of our other decking timbers.
Fitting Methods
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.
Fitting Information
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.
Hardwood Decking Wrench
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.
