The material that we use is United Bonding Primer, from United Coating.

We typically use it on areas prone to early paint failure: tops of deck posts, window sills, etc. One of the other painters in town use it on new red cedar shingles that were then painted white. I was surprised that there was no tannin bleedthrough.

You use that one because you have used the others and it outperforms them by far?

Or just because it is as good and you have easy access to it?

It has been available locally for longer than Peel Stop. I have used them both and get the impression that UBP works better. I have yet to do any test samples to compare the two directly.

They don't always have stain blocking either. So cedar bleed can be a problem. I have used peel bond and peel stop sometimes getting cedar bleed and sometimes not. Unless we use a stain blocking primer over it. Am leaning more towards just priming these days except on restoration type jobs in which case my preferred clear primer is Ppg permanizer plus. My preferred exterior stain blocking primer is currently Bm 046.

Do you ever see United Bonding Primer over on the wet side?
