Default Pockmarked texture on painted interior wall

Hi all,

I am in the process of repainting the interior walls in one of the bedrooms in our home. The walls are drywall, and paint is a flat latex Behr, in the same color I painted the walls about 12 years ago. I've been rolling the paint with a Purdy 3/8" nap roller, and a good frame.

On the biggest wall in the room, I am having a very frustrating problem where a pockmark texture is appearing in certain areas. It looks somewhat like the surface of the moon. This isn't particularly visible from straight on, but when the wall is viewed from an angle, especially in the morning light, it's quite obvious.

In an attempt to fix the problem, I have repainted the wall numerous times using different techniques (the W/M pattern, rolling the entire height of the wall, etc.), and have even primed the wall and repainted it. Nothing has helped.

Can anyone explain to me what's causing this effect, and how I can fix it?

Thank you!
-Dan

Sounds like your drywall needs to be skimmed as it may have little pock marks in the finish that are showing up.

Or I could be misunderstanding and you have little tiny bubbles forming on your paint finish that is later popping.

What type of finish are you using as far as product and sheen?

How much of the surface is effected by this problem?

Got a pic so I maybe we could get a visual to the problem?

Yes a pic would help, also a fatter cover, like a 1/2 in. will help. 3/8 is to small(IMO) I will NOT comment on the paint brand selection

The same will occur if you are using water based paints over an oil finish.

I missed the brand and sheen in the OP.

I would agree with Chrisn as well for flat at least a 1/2 I will use a 3/4 sometimes but some novices may leave to much of a stipple so a 1/2 is a safe bet.

Try rolling out some of the paint onto a spare piece of drywall. If the problem occurs again, its an issue with the paint and I'd switch to a different brand. Could be a bad batch, it dose happen.
