Usually 3mm is for decking as the gaps are tight and clean. 5mm is used for boardwalk applications where more ventilation is desired. Get in contact with us today to see what is right for your next project.
To replace a board that has been previously installed with Shadowdeck™ Hidden-Deck Fasteners, use a reciprocating saw to cut all the Shadowdeck™ fasteners along the side of the board that is farthest from your house or building. Now carefully pry out the board, working from the side on which you cut the fasteners. Use a standard biscuit cutter to cut slots (kerfs) at each joist on the side of your new deck board closest to your house or building. Now install the new board, sliding the slots over the existing exposed Shadowdeck™ Fasteners. Fasten the opposite side of the new board using screws and plugs at each joist. Use the correct size drill bit and countersink and drive in the provided screw.
Biscuit cut your butt-end. Joins must always meet on a joist but end-joint biscuit adds strength to you join. Glue join with exterior construction adhesive is a good option for strength.
One box of Shadowdeck™ Hidden Deck Fasteners will give you 250 fasteners and 25 butt-end jointers.

Allow air to flow freely through the skirting, as well as below the deck. Ventilation is essential for a deck’s long term stability. Lack of ventilation prevents water evaporating quickly or draining through your deck, creating a constant source of moisture on the back of the deck boards. Moisture can lead to cupping with some brands of decking.
Shadowdeck™ Hidden Deck Fasteners work with boards 19mm to 40mm in thickness.
Our fasteners are also ideal for heavy-duty applications such as docks and boardwalks.
