Primer bubbling


I am redoing my family room. I removed the wallpaper that was there. There wasnt any glue left behind, came off nicely. I washed the walls down. I needed to fill in a few holes and flaws in the drywall so I bought the mud that is pink when wet and turns white when dry. I sanded the areas when it was ready, wiped the walls down again in those areas. I rolled on a coat of new primer and when I went back to look at what I had done, I noticed a lot of bubbling only in the areas I had applied the Drydex. What the heck is going on. This is the second time I attempted to fix this. The first time it happened, I sanded the areas down, bought the new Drydex Spackling and tried again. Im at a loss here as to what to do next. Should I hire someone to help me or what should I do?? Im in tears here!!

Primer bubbling


Can you take a pic , host it somewhere and link it here?

Also- what exactly was the primers that you are using?

The pic will show- but explain bubbling a little better- Small pin sized bubbles, or blisters the size of quarters, or a cottage cheesy kind of look?

Primer bubbling


Ever bought a Butterball turkey with a pop up thermometer in it? Those things finally pop when the poor done bird has been killed a second time for sure. People fall for them though even though an instant meat thermometer and common sense would have told them that pulling the bird out an hour or more earlier, and letting it rest for 20 minutes might have kept it edible.

I have about the same amount of faith in indicator mud. From what you are describing, the surface may have gone from pink to white but the rest of what you patched is trying to dry underneath your primer---and if you could see it is/was still pink. I think this because it is only happening where you patched.

Whatever you do, do not cry. We will help you if we can.

I bet the primer calms down as all dries but if not, as suggested, host some pictures and point us to them (I am not sure you can attach until you reach a certain number of posts). Do describe what you mean by bubbling. Many of us have seen strange and mysterious things over the years with paint bubbling. I guess we all cried a time or two. Or used the language of the devil. Most causes are easy to source by the time we get out of the business.

In the future, you might think about learning to mix your own dry mud for these kinds of situations. Bags of the stuff cost very little and if you store one opened in a Rubbermaid container it will last a long time. Hot mud is sold by the theoretical number of minutes it takes to cure in 5-120 minutes. It is nice because you can control its consistency. 20-45 is probably a good starting point for a diyer. Mix small amounts in a nice mud pan. You will not need a color indicator to tell you when it is dry. A nice drywall pan will come in handy as will a wide knife.

Just to be sure not to miss something. As BJ asked, what primer are you using?

Primer bubbling


I agree the pink stuff is gimmicky and can be misleading.
The three types of "bubbling" each indicate different things.
Small bubs will be air trapped in the mud.
Quarter might be more of what Sds is saying- the mud wasn't really dry and moisture is trying to get out.
The cottage cheese would be that you thought there was no paper paste left- but there was. And the moisture from either the mud, the primer or both are reactivating it.
I always prime with Gardz (or oil, but i prefer Gardz) after stripping and removing paste, before mudding. This gives a fresh start to the whole thing by making a vapor barrier.
At this point I would probably prime it with the Gardz- like I said- like hitting reset.
Then fix , reprime and finish.

Do the Gardz like BJ suggests to seal away lingering problems. Then patch, prime the patches and paint as he suggests.

Never race your materials though. If you are not sure whether patches or primers are dry? Let them go a bit longer.
