Hello, I recently painted a wooden trellace. I primed all the wood first with an oil based primer (kelly moore 220 oil based primer) i gave it plenty of time to dry, i then went ahead and painted it with kellymoore 1250 exterior semigloss enamel upon the home owner's request.
I was called back due to the fact that some of the paint on the trellace was bubbling. I was surprised since i have never ran into problems of this sort. I went ahead and started to fix the damage. I began scraping away the bubbling paint and noticed that under the bubble there was sap. And as i looked at the rest of the wood there were spots where sap was just oozing out of the wood. so i went ahead and fixed the bubbling by cleaning off all of the sap, scraping, sanding and priming. i repainted the damaged spots.
it came out looking great, and it seemed like the problem was solved until early today, i took a look at it and there was the sap oozing out again and also some more bubbling.
well i have come to the conclusion that what is causing the problem is the sap, but how do i stop the sap from coming out? is there a special product or primer to stop this?
like i said i have never seen anything like this.
