Which assumptions are you assuming to be wrong? After rereading your
post, I have surmised that the problem is not your brush or how you
clean it, but the wrong primer for particle board (possibly). PB has
water soluble glue and the water based paint dissolved some glue (along
with fine wood particles?). Oil-based primer would probably be better
choice.

Comments applied to previous attempts posting to obtain assisstance,
using brief descriptions.

I never thought of the glues in the particle board reacting with the
paint, not bad. Second coat should NOT have that problem, but was
actually worse. But, that might have been caused by waiting only 24
hours for the second coat, and the paint was not cured enough and IT
reacted with the new paint.


Don't know, never had such an issue, but....first coat dissolved some
glue which sucked water from the paint and kept it from curing. Second
coat dissolved the glue/paint again with partially cured globs.

When latex paint first came out, my mom used it over wallpaper in a
bedroom. The wallpaper shortly started coming off the wall...kind of
like a Laurel & Hardy job...mom kept sticking it back up. Mom won (as
usual) )
