We recommend screwing a deck down. Why?
Firstly screws have better holding power than nails. A good screw will pin your deck tightly to the joist, ensuring less chance of lifting and movement. The decking itself is less likely to distort and crack.
Secondly, screws can be removed easily, without damaging the decking itself. This is ideal if you need to access underneath your deck, or replace a decking board.
Always use a hot dipped galvanised or stainless steel screw. Anything else is unlikely to last the distance. Stainless steel is the preferred option, especially if your deck is near the coast.
Avoid over driving your screw, or getting a little carried away with countersinking. Over driving or excessive countersinking can cause moisture to pool around the screw head. This will be the first place your deck begins to decay.
Another critical success factor is the application of an end sealant. Wood absorbs significantly more moisture up the end grain. This moisture will sit in the end grain of the decking, eventually causing decay. Even in “Class 1″ durability hardwoods, it is almost always the end grain of decking that rots first.
Use an end sealant like Protector - End Seal to seal then end grain, and to provide additional protection to this vulnerable part of your deck.
