I got a leeeeettle over zealous while doing some sanding on the new drywall and mud....and now I have drywall fuzzies in some areas. Please tell me the SW PVA primer/sealer will lay these down when I prime.

note to self don't sand without a light :mad:

Jmayspaint.......not sure about the top notch drywall job in this house but its a whole lot better than nekked studs that's for sure lol.

Matthew - pva was the recommended sealer/primer for new drywall based on the research that I did. I am looking forward to seeing what it does with new drywall as I have never dealt with new drywall on such a large scale. We shall see.

I know, it gets recommended by a lot of people but for the life of me I can never figure out why. It is way too thin and too clear in most cases to even make it look like you even did anything to the walls.

My understanding is that PVA is used mainly because of its adhesive qualities on drywall.

Polyvinyl Acetate (PVA) itself is colorless, so any coverage it provides comes from the colorants and other additives.

The new house I used it in recently was my first experience with it.
The SW PVA seemed thick in the bucket, actually somewhat 'pasty'
It applied quite smoothly

How to huff glue legally :laughing:

Well last night I primed 2 rooms with the SW PVA primer...This stuff is either really forgiving or I am just that good with the drywall (I'm going with the latter lol).

Seriously, I cannot compare it to other drywall primers as I have only ever done one other little drywall job and we just used regular primer.

This stuff went on smooth and really laid down the fuzzies. Have a couple of spots that are flashing but I think that is more because it was at the end of the job at some ungodly hour this morning so I don't think I was consistent in a few spots.

Very happy with end result. Only drawback is don't paint this stuff in a small closet without a fan...stiiiiiiinky. Light sand tonight and then on with the Final ceiling coat.

Well, I hope the PVA works for me as good as it did for Robin. The new house I started yesterday has the fuzziest drywall I have ever seen. They sanded it all with a big 10" pole sander. The nail mud which is about 3-4 inches wide has 5-6 inches of fuzz all around it. So far it's laying down pretty good.
I will have to really sand well, the finish is eggshell.

The problem I have encountered with PVA is it covers bare drywall OK but on joints with mud it sometimes will let the mud flash.
Tool, I have just ran into the flashing problem myself. I sprayed an back rolled the PVA yesterday morning. Early this morning I noticed flashing of the mud. The top coat has been drying all day, and its flashed through it too. Not terrible, but definitely noticeable. The finish in SW Cashmere low luster.
Will another coat improve this? The second pic is the top coat. Hard to see it in the pic, but its definitely there.....

Jmays - I used the SW pva and it had no flashing but then I rolled it on with a 1/2 inch roller and did not spray it. I make enough mess with just a roller.

Lets just say its a good thing there is still only concrete flooring. :eek:

My only issue was one spot that I didn't sand real well that I had to go back and spot fill and then hit again.

Serious question, does spraying put on a thinner or thicker coat? I know its a more even one but curious if spraying is thicker or thinner. Never sprayed so really don't know.

"Does spraying put on a thinner or thicker coat"

It can really go either way. With a sprayer, you have more control over the coating thickness, so Whether the coat is thick or thin is determined by the technique of the person spraying. The same thing is true with rolling.

Spraying has the potential to put on a very thin coat, and it is often done that way. But it doesn't have to be.

Personally, I pay close attention to coating thickness, as I feel it's very a important factor in how paint performs. I have posted this before, but this is a simple tool used to measure the thickness of a wet coating. It's called a 'wet film gauge'. If you ask, they will usually give you one for free at SW. The little teeth on the card sink into the wet coating to varying degrees to give you a good idea of how thick your coat is. Most interior latex paints are specified to go on between 3.8-4 mills.
