blisters and peeling paint
This seems to happen to me every time I paint. I am putting primer on my walls after patching and skim coating. As I roll the primer on, some of it blisters and some of it rolls right off the walls with the roller. At first, after I did one area, I thought maybe I left some dust on the surface and that is why the primer wasn't sticking. But I did another section and made sure that I vacuumed and used a lightly damp sponge over every inch. I again ran into the same problem. I noticed that the area where the primer doesn't stick is where there is joint compound and it feels a little "muddy" (it was not this way before I applied the primer), so now I'm thinking that this is a moisture problem.
Here's what I did:
1) Applied joint compound (final coat)
2) Waited about 4 hours for it to dry
4) Vacuumed and wiped walls with slightly damp sponge to pick up dust
5) Waited an hour for the walls to dry
6) Applied primer
I checked the joint coupound bag - it says wait for it to dry before priming
I checked the primer can - it says make sure walls are dry
I checked the internet and I mostly see "wait till the walls are dry" or wait overnight.
I am suspecting that the joint compound actually needs more time before priming.
The primer is Zinsser PrimeCoat2 primer/sealer.
If you know what I'm doing wrong, please tell me.
