seal holes in deck joists before replacing boards?
#6
  
I have a ground level deck surrounding an inground pool, made from PT SYP with the deck boards held down with hidden fasteners.. I had to pull up a course of 10 boards to do some repairs to some pool plumbing below it.  Is there a product I can use (like a "tar" or some such) to paint over the joists before placing the boards back down, to seal up the existing screw holes before screwing the boards back down again, to help prevent rot?

Roofing tar is available in caulk tubes

The Revos apparently are designed to clamp railroad ties and pull together horrifically prepared joints

They make a rubber tape for that application.

If you are exposing the joists this is a very clean and neat application.

It is 3" wide, by 75 feet from Home Depot for just under $30.00 per roll.  Not cheap but fast and easy.

sweet! Wish I knew of that stuff when I made the deck 12yrs ago. Surprisingly, the joists I have exposed are all in pretty good shape.

edit: is this essentially the same thing as window flashing? I have a couple extra rolls of that lying around.

I think it is, just slit to a narrower width.  I would use the window flashing.  If it is 6" or wider you can slit it with a knife and double the available length.  Obviously screws will have no problem going through this stuff.  And unlike roofing tar, you should keep relatively clean even without gloves.
