Sealing new Drywall b4 Paint


what does sealing do for new drywall and is this necessary? I am going to prime my new drywall and there are a bunch of primers with sealers.

The tint in the primer hides the gray colour of the drywall and preps the wall for a more durable and washable finished surface.

What you want to do is use a high quality PVA primer the mud and tape and the paper of the drywall is porous and if you don't use a PVA primer you will use a ton of paint. because the sheetrock will soak it up. A good PVA primer will cost around 45 dollars per five gallons.

name one

I will take exception to the quote in greeen. Any quality primer will seal the drywall, mud, tape etc., without using a ton of it. I prime new drywall almost every day and NEVER use PVA primer. I have found that at least in the past that it was a very inferior product. Maybe it has changed. Me, I am not going to find out.

$45 for a five says it all

Yep, even that is overpriced for PVA.

Not really the way to look at it as a LOT of paints have PVA. If you take out almost all the ingredients in paint or primer you are left with PVA (Polyvinyl Acetate). For a primer to brag about having PVA in it is like it also bragging that it has water in it.
