Painting New Construction Interior Walls - PVA Primer

What happens here

The presenter discusses the importance of using a PVA primer specifically designed for drywall. PVA primer seals the porous drywall and drywall mud, preventing paint from absorbing unevenly into the surface, which can lead to 'flashing' (uneven sheen or color) in the final topcoat. It also ensures proper adhesion of subsequent paint layers and seals in drywall dust, which can cause adhesion problems if not properly primed. The video warns against using more expensive multi-surface primers like Zinsser 1-2-3 or Cover Stain as they are not specifically designed for drywall's unique needs and are an unnecessary expense.

Goal: This step explains the critical role of PVA (Polyvinyl Acetate) primer for bare drywall and drywall mud, emphasizing its sealing properties to prevent adhesion issues and ensure an even topcoat finish.

All right. So, we're out here getting ready to uh do our priming and we're doing the prepping, mopping the walls, vacuuming, cocking windows, and masking off. I'm going to talk a little bit about uh the primer we're going to be using. It's a PVA primer. If you've never heard of term polyinyl acetate, and that's a primer specifically for drywall, bare drywall, or drywall mud. It's not a primer for anything else but drywall. If you don't use a PVA primer, some of the challenges you're going to run into, you know, is your paint sticking to the walls. You've got, you know, the sanding and stuff even after mopping. You've got drywall dust on your walls that'll cause adhesion problems if you just try to put a paint over the top of that and you don't prime it with a proper primer. You don't want to use other primers, you know, say above like a PVA primer like Zenzer 123 cover stain multi-urface primer, you know, stuff like that because it's just expensive primers and it's not designed to do what this stuff actually does. A PVA primer goes on and it seals your sheetrock and and what that does is it makes it so your top coat that eventually goes over the top of that will be even across your entire wall and you don't get flashing. You can see we got exposed drywall paper right here where the mud is um not covered those areas. This texture right here is called a sun valley texture here in my area. Some people might call it a skip tri. Some people might call it something else. If you're not f familiar with the term here in Idaho treasure valley it's called sun valley texture with a hand texture on the ceilings. Once again it's extremely important to seal this with the proper uh PVA primer. PVA. Once again, poly vinyl acetate. It's going to seal this bare drywall paper. It's going to seal the mud. It's going to seal everything. So, your top coat when you spray it on, it's going to look professional. It's going to look nice and it's going to look even. So, you want to use a PVA primer irregardless of what other what other types of textures you do have on there. You could run into orange peel textures. You could run into your level five finishes. There's a lot of different textures out there, but use the proper primer so your finish looks like a quality finish and like a professional did it. All right, I've
