I am going to paint a pressure treated swim platform with a polyurethane
paint intended for truck bedlines.
The manufacturer says it adheres to wood just fine, but on PT they recommend
a primer first, but do not suggest a specific primer.
Any suggestions for an appropriate primer? (or a different coating
entirely? I was planing on using fiberglass, but that can't handle the wood

I've used both alcohol-based and acrylic Bullseye or Zinzer for PT. These
brands are especially good for sealing knots and bleeding pitch areas, and
really adhere well to the wood. I think the thinner or alcohol based
versions are the toughest, vs the acrylic. One variable might be the
"freshness" of the PT. Some is actually almost wet with chemicals, and may
interact with some paints. Make sure yours looks completely dry before you
Truck paint is made to cure rock hard, is not designed for expansion and
contraction that is necessary on exterior wood. Use a paint for wood
from a top company like
Sherwin Williams, Ben Moore, etc. They also carry commercial coatings
and will steer you right.
Use the Right product for the Right job, and follow their instructions.
New PT must cure- dry out.
Thanks, alchohol/Bullseye it is. I am using used wood because it was free,
and on the theory it has gotten warping out of its system. So it had better
be dry! Once I planed the weathered surface off, it looks great.
With most PT wood, planning the surface off takes away most of the
treatment, exposing the untreated or very lightly treated wood to decay or
insects. That is why they sell end cut treatment, because you cut through to
expose the untreated core.
Which product made by Zinsser is alcohol based? BIN is shellac based
and is cleaned-up with alcohol but is not recommened for exterior use
except for spot priming since it becomes too brittle for large
A primer is always a good idea for a better paint job. Use the same
brand primer as the paint. The trick with PT wood is to allow it to
thoroughly dry before you paint. Wet wood can take 1 year per 1"
thickness to dry.
