Probably going to sound stupid but what colour does this leave on an interior wall? Would it be black or dark gray?
Asked by: CinderEllie
Great question! Rust-Oleum Zinsser Block Filler 2X Primer offers a white finish once applied, but it can be tinted with up to 2 ounces (59 mL) of universal colorant per gallon to improve the hiding power of the topcoat if desired. - Rust-Oleum Product Support 3

I'm planning to use this on my interior cinder block basement wall that was recently waterproofed on the exterior. I have some cracks on the interior wall and plan to use block filler and then some kind of elastomeric paint as the top coat. How do I handle filling any cracks on the wall? Should I apply elastomeric caulk or hydrolic cement? Should this caulk or cement be applied before or after using the block filler? Thank you!
Asked by: SamAlex
I would use any waterproofing material first then apply this to even up surface. I used it on Osb flooring to even out before putting down new flooring

Will this fill the holes in my cinder block wall? I want a smoother surface before I paint it.

Asked by: Jule
This will seal the block and fill small holes but I wouldn't say smooth. However, sealing the block keeps the paint from being absorbed into the block and will give you a uniform finish.

I'm looking for a thick primer to reduce the look of orange peel on my walls from years of bad technique painting, will this help? If not, does Zinsser have a different primer that will help? Planning on following up with regular flat paint.
Asked by: jess
No this is not the product you need (maybe for painting brick). Buy a box of plus 3 joint compound and a large 8, 10, or 12" Taping knife. Sand wall and then skim coat entire wall (Press firmly). Wait for it to dry, then sand lightly. Repeat if desired for a smoother wall. Just a caveat: This will be dusty! Then apply two coats of decent paint with a 1/2 inch nap roller..
