Can I put screws through the Supreme boards?
We do not recommend puncturing the boards with screws as this will affect the structural integrity of the boards and void its warranty.
The exception to this is when fitting the final board in a run of decking where fitting requires a screw being fitted through the side of the board at an angle to fix it in place.
What clips do I need to fit the Supreme boards?
The Premium clips are used to fit the Supreme boards, we recommend 100 clips for every 10 boards you order.
You will also need starter clips to fit the first line of decking boards; the amount will vary depending on your design but usually 1 pack of 50 starter clips should be enough to cover areas up to 60m2.
What are the recommended joist spacing for the Supreme boards?
The recommended joist spacing for the Supreme boards is 400mm from centre to centre.
What expansion gap should I leave at the end of the Supreme boards?
There are a few factors to consider when leaving an expansion gap:
- The ambient temperature
It is safer to leave a 10mm expansion gap between boards when laying them in average temperatures.We do not recommend laying the deck in extremely high (>20°C) or low (<5°C) temperatures as this could result in the boards not having adequate expansions gaps during average temperatures.
- What you are butting the board up against
When butting the boards up against a surface that will not expand, it is fine to leave a 5mm expansion gap (dependent on the ambient temperature as mentioned above).
When butting boards up against each other (end to end) it is important to leave a larger 10mm expansion gap. This allows adequate space for both boards to be able to expand when the temperature rises.
Failure to leave enough of an expansion gap can result in warping or splitting of the decking boards.
Which side up should I lay my Supreme decking boards?
The supreme boards are a single sided decking board, it must be laid with woodgrain side facing upwards.
What should I use to cut the Supreme boards?
We recommend using a sliding electric mitre saw circular saw with a minimum of a 40 tooth alternate top bevel finish blade.
