Hi all, what nails do I need to fix 18mm cedar cladding ? I've fixed a 38 X 70mm frame at 400mm centres. I wanted to secret nail it and longest length is 1800mm. I know I need stainless steel nail at 50mm? Is lost head nails ok or will they pull through? Thanks
Is a brad sturdy enough? It's on the exterior? I have a Senco Brad nailer up to 18ga ? I only have 6 m2 to dos a can take my time. I had a look on eBay at stainless steel nails and there is lost head and flat head? How many 50mm nails would be in 150g? They sell them by the weight
stainless annular shank nails are best, lost head type - you don't want the nails sticking out above the surface . You're supposed to leave some room for expansion, so there's 2mm or so gap between end of tongue and groove, if the profile allows, make up a spacer to fit in the groove and then tap each length down to get even spacing.

Many thanks what gauge nails should I buy? I saw some at 3.5mm ? Seems quite thick ? Also at the bottom I'm hanging vertical is there any point in cutting the bottoms at 45 degrees? So it has a drip built in ? Or just cut at 90 degrees and the water will run off or would it soak more into under edge ?
I've found these http://www.tradefixdirect.com/stain...s-steel-annular-ring-lost-head-nails-50-x-3mm Would they be ok? I could always drill with a 1mm drill first to stop it splitting, I'm going to secret nail them.
I think those nails are fine. Drilling first is a good idea, then punch the nails home, it's quite easy to split/damage cedar if you're not careful. Bevelling the bottoms is a good idea to minimise water sitting on the end grain and soaking in. Ideally the space behind the boards should be ventilated, by e.g. counter battens, and using mesh sccreen to keep insects out.
If you are talking about fitting cladding vertically then it is better to undercut the timber than beveling it
Instead of cutting the bottom edge (nearest the ground) square, cut it so that their is a slope backwards. This way rain water drips off
That explanation is not very clear. What sos means is to cut the bottom edge of the board at a 45 degree angle. This brings the wood to a point, reducing any surface area for the water to collect on, where it could be 'soaked up' by the cedar. Taking this simple step can add years of the life of the boards.
Thanks, One of the problems post head injury is that words don't always come out the way they should do
