Drywall Pin Holes (Air Bubbles)


I went to look at a new job on Friday. They’d had an addition put onto their home a couple of years earlier. The first thing the customer pointed out was pin hole in the drywall patches. I have seen this many times and said that their painter should have touched them up. (Home owner did the painting). They were very unhappy with the job. Personally the taping was spot on. There was pin holes….

What do you think causes this? It has been a common problem.
What is the solution? Besides passing it onto the painter.

Come on, fess up, you're just trying to provoke
another "soap-in-the-mud" thread!
The last one was only about a month ago.

If that is the ultimate question...then the number "42" does not exist.

Re: Drywall Pin Holes (Air Bubbles)


The drywaller finishes sanding and then the stupid homeowner takes a vacumm to it exposing pock marks. You should only wipe off any excess dust.

Re: Drywall Pin Holes (Air Bubbles)


If this is a serious question, then the cause is air migrating from the mud to the outside. Since it can't go back through the wall it comes out the front making the bubbles. soaping you mud may help, I have never tried it. Mixing your mud to a smooth consistency will help. So will wiping it tight on your second, third and fourth coats.

It is more prevalent with AP mud or any mud over a painted surface, like when you are remodeling.

Re: Drywall Pin Holes (Air Bubbles)


I find the holes happen when mud is put on too thick or it is put over paint. Put mud on in several thin layers and as for mud over paint, despite a thread on this site with dozens of ideas, I still can't get rid of them. Repeated layers of mud seems to eventually get rid of them if you have the patience.

Re: Drywall Pin Holes (Air Bubbles)


pin holes in mud is because they pulled the mud to fast across the surface of the board, when you do this air gets traped then comes to surface once it drys you get pin hole or pot holes, the Painters are suppose to spackle, this is something Home Owners don't understand about painting they think once the drywall or plaster is done it should be free of any inprefections, this is why there are Painters who know how to paint. I just did a bid where a Home Onwer had her friends do the drywall, well they used all mesh tape and all their joints cracked. she asked me to come in and fix it. Just like a Home Owner. DIYer's are a funny group when their job doesn't turn out right.

I am a painter and know how to paint but would expect the the dry waller would know how to apply mud and leave me with a finished product( his or hers job) so I can do my job.Yes, as a homeowner,I would expect when the dry waller is done that there would be few imperfections.

Re: Drywall Pin Holes (Air Bubbles)


Well as for painters who think drywallers are to have prefect walls please. Painters now a days do very little work.When I started out some 28 years ago we had to mix our own paint colors they didn't mix it up for you. we also had to do all patching of anything smaller then a quarter now painters are just Blow & Go they don't spackle or caulk or even putty they just want to paint. I bet very few painters even know how to mix colors or make up wood stains colors. Home Owners are bad enough when it comes to filling pot holes but when Painters complain well I guess they really aint Painters. Just Blow & Go cause they don't know how to paint

in smoth wall finishing, after sanding the 3rd coat, take a damed sponge and wipe down all joints and nails or screws, then using a light to veiw the walls use mud with a small amount of blue chaulk mixed up in it. then touch up all pin holes and other inperfections. then you go back to the blue spots and sand off the edges.

Just Blow & Go cause they don't know how to paint
To bad you couldn't find a paint store.
In 1980 they all had tint machines,
as did every Sears Roebuck, and 90%
of all the Mom and Pop hardwares.
Oddly when I pay a drywall finisher,
I expect him (or her, Raven)
to finish the drywall!
I expect the painter to paint it.

AH!! I like that, the blue chalk.

This is what I do, but with out the chalk. I don't have to many problems when I'm finishing or repairing, but it does happen on occasion.
