I am having problems applying Behr Premium Plus Interior flat paint on
primed drywall. I am getting bubbles and sags in the paint after I roll
it on. I am used to rolling the paint on in a "W" shape, rolling again
to spread the paint, and then backrolling once more - a total of three
passes with the roller for each section I do. Now I have to roll each
area at least one more time to smooth out the paint. After that, I
have to re-roll some areas that have been down for a few minutes
because the paint is sagging. Thanks for any help.
If the paint is sagging, you are putting on too much. What kind of
roller cover? Should be short nap unless textured wall. Don't load it
so full. Tiny pinpoint bubbles may appear if you are rolling an area too
much, but most level out.
My experience with Behr paint is that it doesn't lay flat, the texture will
be different when I roll forward to when I roll back, showing up the roller
marks. While Behr is not regarded as a great paint, you should not be
experiencing sagging as you are unless either the paint is defective or the
surface is contaminated. I suspect it is probably contaminated with oil or
grease, possibly candle wax film or evaporated oil scents or a too fresh
coat of oil paint.
I would scrub a short section of unpainted wall with a TSP or
detergent/ammonia water wash, with a clean water rinse and see if that area
accepts paint properly once it is dry.
I would suspect the primer (was oil based and was it recommended for
latex paint?) and or contamination of the printer's surface and or an overly
heavy application of the new paint and or insufficient mixing of the new
if it's not the surface and it's not the painter it's the paint. return
it they will replace it for free. check other posted advice. we've
never had a bad can of behr, but there's always a first time.
note to beginners: read the whole can and follow temperature directions
and mix thoroughly.
The wall was primed with latex primer and I mixed the paint well. I
did fail to mention in my original post that I have this horrible
medical condition called laziness that has caused the paint to sit for
well over a year. Behr tech support told me to try thinning it a
little, and I might try a shorter nap roller.
Thanks to all of you for the help.
As long as the can was either new & unopened, or partially used and then
closed correctly (without damaging the seal), year old paint shouldn't be a
problem. You sound like you're fully functional from the neck up, so your
mixing method was probably fine. But, if you're dealing with primer, you can
also shake the bejeezus out of the can, being sure to invert it often.
