We just had a screened porch added to the back of our house. It's really
great, especially now that the weather is warming up a little here in N.C.
I need to seal the floor, which is 3" plus wide tongue and groove pine - it
is not pressure treated lumber. It is 12' x 13'. I have a few questions:
1. Should I paint it with a deck paint or use a polyurethane? Which would
be more durable?
2. Should I sand it first? Are there any issues regarding how long a coat
of paint will last if I don't sand it smooth? It has curled very slightly,
but not so much as to make it hard to slide a chair, etc. There are slight
gaps between the boards, but sanding won't help that. If I can paint
without sanding I would be a happy camper. we don't mind a rustic look.
3. I think we're leaning towards an oil based deck paint, instead of a
stained or clear finish. What brands of deck paint or clear finish are best
for this application?
4. What can I do to the primer and paint, if anything, to make sure it seals
the gaps as much as possible?
There will probably be other questions, but that will get me started.
