Well,,,this makes two sour jobs in a row where Zinsser waterborne primer failed miserably..
The first one, about six months ago, I sort of chalked up to a bad substrate and/or some sort of contaminate.
This one though is different. I know what material was used, how it was applied and the enviroment it's in.
Both Zinsser Bullseye 1*2*3 and Zinsser Fast Prime 2 were tried, on seperate walls.
Both ended up bubbling on the surface and blistering. The blistering went down to the previous coat - which means that the lack of adhesion was between the Zinsser and what was on the wall.
Some parts of the wall even blistered down to the drywall compound I used to patch with.
@ this point, I'm done w/Zinsser except for B*I*N and their shellac products.
I'm going to switch over to Kilz and see if it's still a decent material.
It's a shame since I've been using Zinsser products for over 40 years & it just seem to be recently, since Zinsser was taken over by RPM, that their primers have gone downhill.
I have to believe @ this point that either RPM has altered the formula to either cut costs or to comply w/VOC regulations.
I know there's a fair number of DIY'ers here that use primers/sealers on a regular basis.
My advice would be to be somewhat wary of any of the Zinsser waterborne primers.
This one would have hurt had it set back the schedule the two days it's going to take to repair the walls.
Fortunately, the tile guy is tied up until Thursday & I have tie to sand, patch and repaint.
