To cover 1m² with 4 in (100mm Nom.) decking you need about 10 running metres of material.
To cover 1m² with 6 in (150 mm Nom.) decking you need about 7.1 running metres of material.
We recommend about 40 screws for every metre square.
Remember to order slightly more boards than you will need, this way, if you find yourself one short for some reason, then you won’t have to go to the hassle or expense of ordering more.
Handy hint: any left over deck boards or off-cuts can be used to make smart planters that will match your deck.
