Can you use drywall primer on painted walls.

The solution to those minor imperfections is a high build drywall primer sealer. Unfortunately it doesn t stick well to gloss or semi gloss paint. Use primer if you have fresh drywall drywall and drywall mud absorb paint more than previously painted surfaces which often don t absorb any paint. This means that your first coat of paint can actually be absorbed into the drywall making it act more like a primer than paint.

If you have ever looked at a painted wall from a sharp angle and seen the finished joints show through this is an effect called joint banding or flashing. But if you re like most of us your finished drywall probably has some tiny pockmarks fine ridges and scuffed paper from sanding. If the drywall primer is something like kilz or zinser you can go ahead and use it. This means that after you apply the primer you can use a sanding pole like my favorite the radius 360 sanding disc to smooth out the walls to a perfect finish before you apply the topcoat.

Primer equalizes porosity drywall primer soaks into the paper scuffed paper and mud the areas of differing porosity and creates a uniform surface to which the finish paint can adhere. A coat of primer provides the necessary adhesion and another one. This will work best if you are keeping a similar paint sheen and color to what is already on the walls. If you re an ace drywall finisher and your walls are perfectly smooth you can use a standard drywall primer sealer.

You use drywall joint compound for almost all drywall repairs. If it is a pva primer then i d suggest you go ahead and purchase kilz for this project. Painted drywall drywall compound usually will adhere to a surface painted with a flat or dull paint.

A primer or sealer or a primer sealer is essential when preparing new drywall for paint or wallpaper. Improves the glide and spread of top coat. After you re done hanging drywall and all the seams are taped and finished you need two coats of paint to give the wall its final appearance. However a glossy paint enamel or paint intended to repel moisture such as bathroom paint may not hold the compound as securely.
