Sealing Plywood

[Searcher7]

I just finished making a plywood door for a game cabinet The original door had been made of particle board, but the 3/8" lip on both ends had begun to disintegrat over the years.

Since the disadvantage in using plywood is that it tends to warp, is there a good way to seal it to prevent this before I prime and paint?

I have something called Thompson's WaterSeal, but don't know if I should use that before I prime with an Enamel Undercoater Primer/ Sealer (by BEHR) I have.

Any recommendations?

Thanks.

Whatever you end up doing be sure to do the same thing to both sides of the ply. Art

Yes. Not to mention the edges.

I just don't like the idea of having to go out and buy something else when I already have a sealer and a primer/sealer.

------------------------------------------------------- Swing already put this to bed.

Dewaxed shellac.

I'm not going for a clear finish. The door has to be primed and painted black after I seal it.

You wanted a sealer which is what dewaxed shellac does and it also serves as a primer for the raw materials.

I'm assuming you are saying that the sealer/primer I already have is not go= od enough, correct? And that Zinsser Bullseye=AE SealCoat=99 can be painted= over?

---------------------------------------------------------- You asked for a sealer for the plywood recommendation.

That's what you got.

Never worked with the stuff you have so can't comment about it's quality.

Zinsser Bullseye® SealCoat?is designed as a sealer that you can paint over.

It is what I would use.

Have fun.

In fact, shellac is a component in KILZ primer.

Zinsser Bullseye SealCoat is 100% was-free shellac in denatured alcohol.

Dewaxed shellac is the best sealer made, can be painted over with anything.

To fill in some blanks in the discussion, I'll add that shellac makes an excellent barrier to water vapor. In other words, it can slow but not prevent warping due to humidity changes.

There are no guarantees on that no matter what you do. One thing that helps is using better plywood but these days it can be hard to tell just what you are getting. I am pretty sure the better plywood won't be found at Home Depot or Lowes.

Ok, so let me get this straight.

Thompson's WaterSeal is a waste of money. Zinsser Bullseye SealCoat works well. And no one here has tried BEHR Enamel Undercoater Primer/Sealer #75.

Thanks for all the ideas on removing the bar-code sticker. I actually wet a cloth and laid it on the sticker for a couple minutes and it scratched off easily after that. :-)
