Do I need to sand?
Hi. I'm going to be painting my kitchen and dining room (open concept, so one room). The paint on the walls now is latex eggshell. The new paint will also be latex eggshell. Right now it is dark red and I will be changing that to a light beige. I plan on applying Kilz 2 latex primer/sealer on the walls first. I've read that you should sand the walls down if the existing paint has a shiny sheen. Would eggshell be considered shiny or is shiny just semi or hi-gloss or satin? In some light, the eggshell appears to have a slight shine, but I don't know if that's enough to require sanding.
Thanks in advance for any advice!

Thanks, Pulpo. Just curious though. Are you saying that in general, if I'm priming and painting I don't need to sand? Or do I not need to sand just because it's an eggshell finish?

Generally you can get by without sanding eggshell/satin enamel when painting over it BUT sanding is always a good idea! You don't have to aggressively sand, a quick scuff sand is sufficient. I use a drywall sanding pole - only takes a few minutes per wall.

Hi marksr.......When I originally read that I may need to sand, the sanding pole was my first thought. You and Pulpo both say I don't really need to sand, but I'm guessing that maybe I'd end up with a slightly better finished product if I do?

Thanks for the quick reply. Maybe it's worth sanding then. I've read to use anywhere between 100 & 200 grit, depending on the website. Do you know which is best?

I would use a different primer - the one you've proposed has known adhesion issues. I use Zinsser primers but there are other good brands as well (including the original oil based Kilz, it's only their latex product which is problematic).

Stickshift....which Zinsser primer would you use? I see there's a few different ones on the H.D. website. I had only picked the Kilz 2 because it had better ratings on there than most of the Zinsser products.
Edit: I'm going to edit this because after further research, I see that the Zinsser 1-2-3 does have some pretty good reviews. I think I may switch to that.

Either 100 or 120 grit is good for sanding the wall.
Good catch SS, I totally missed the reference to Kilz2
1-2-3 is a good primer for your walls although unless coverage is expected to be an issue there isn't a need to prime your already painted walls. Primer is only needed when there is bare substrate, adhesion issues or stains that need to be sealed.

Well, I went to HD and did end up buying the Zinsser 1-2-3. Marksr, the reason why I figured I'd be better off priming is because the walls are currently a very dark red, and my new paint will be a light beige. Would you agree that priming is the right move? And thanks for the info on the sand paper grit, btw.

Ya, I should have added that primer can also help with coverage as in your case when changing to a light color over a dark color. While a primer isn't imperative it can reduce the number of coats needed to achieve full coverage of the new color.
