Some important points about gapping and spacing
As daily temperatures change, all deck boards will expand & contract. Therefore, it is essential to install the boards with gaps as recommended below by Trex. The size of the gaps required also depends on the temperature in which they’re being installed so please check the official Trex Installation guide PDF
All deck boards must always be installed with a 6mm side-to-side gap. The Trex Hideaway Hidden Fasteners will automatically measure the 6mm gap between grooved edge boards but you must still ensure the 6mm gap with the square edge boards.
All deck boards must always be installed with a 3-5mm end-to-end or end-to-width gap between boards.
There must also be a 6-13mm abutting gap between the boards and other objects such as garden walls or houses.
