Never seen this in 40+ years!

Technique even works in other areas. Over Dunn Edwards paint on
interior surface, skim coat using Home Depot premixed ?? in 1 gal
container. this time about 1/16 inch thick. Come back in 3-4 hours and
find the coat dried like a lake bed, curled sheets of around 4-6 inch
sizes, and fell in a pile on the floor! *In other areas of home,
technique works beautifully, and surprisingly feathers in AND touch up
paint using from same lot bucket makes invisible repairs.

Did very conscientiously and again coating doesn't want to adhere. If
keep pressing flat onto the surface stays put, but cracks still form,
fill those and keep pressing. It's almost like somebody took an air
compressor and blew the coating off the wall. Strange. Should the
surface coating applied to be absolutely dry? Sometimes dampened, not
wet, in an attempt to prevent the bottom surface from sucking moisture
from coating.

Any ideas on how to increase adhesion? Add water base glues?

sand area lightly, wash down wall with TSP, RINSE 3 TIMES *prime with
bin or kilz oil based primer sealer, then skim with drywall mud...

the underlying paint was likely gloss, or a wierd combo of paint that
didnt allow adhesion

Thanks for the response, indeed when confronted with gloss I always
scuff sand with 120 up to 220 grit just to 'break' the surface down.
but this paint is flat and used throughout the whole house.

what is 'confusing' to me is that the exact same materials, including
paint, is everywhere. And I just got done putting a thin, thin, thin
skim coat and same paint over it in another area NO PROBLEMS. Plus, in
another area over the same materials, a thick skim coat that wasn't
flat enough, so applied another feathered layer, and another, again no
problems.

just weird, that this one location eveyrthing seems to act
differently.well actually two locations. no moisture around either .
