There are 6 or 8 spiral nails on our deck that will not stay down. The
boards are flat on the deck and do not appear to be cupped or warped.
But, within about 3 months of driving the nails down, they are back
Should I pull the nails and replace them with the next size larger
Should I pull the nails and replace them with coated deck screws?
Email hint - Everything after the @ is spelled backwards.
Deck screws hold the best, but it's your call about whether the
different fastener heads would look objectionable or not. As an
alternative you could take out the offending nails, coat a couple of
toothpicks with exterior wood glue and insert them into the hole
before hammering the nail back into place.
Our deck was built with mainly hot galvanized nails, some 20 years
ago. A few planks were screwed down for easier access underneath (cos
the deck is an average of 15 inches above ground) It has P.Treated 2
by 8 joists on very substantial underpinnings and is also planked with
PT 2 by 8.
It hasn't had any such 'nail popping' problems. But if was building
today would use proper 'decking screws'. Try a few screws as
replacements of popped nails and see if the underpinnings are still
intact enough to take the fasteners ........... or if not maybe
something starting to rot or shift?
If you want to stay with nails then use 16d spirals in new holes. My guess
would be the deck joists are soft or chewed at that spot. Are the
particular ones even hitting a joist? Take a gander underneath (aka crawl
and get really dirty) if you really want to know. If it appears the nail is
not biting and it's not for a goofy reason like they're 8d's, you could
sister or scab a PT 2x4 on the existing joist and renail.
