Questions & Answers

Can you prime previously painter interior drywall and ceilings?

Asked by: Johnnywalker
Yes. I primed both previously painted and unpainted block walls in my basement. I did apply two coats of primer to unpainted wall versus one on the painted wall to ensure a uniform appearance.

Can this be used on cinder block basement walls which have some hairlne cracks? Directions say not for below grade use?

I see other reviews where this was used i interior basement block walls?
Asked by: Kriz10
Our basement walls have some small cracks and this covers them up. Maybe the below grade restriction is for exterior use.

Do I have to paint over this? I plan to put on a block wall fence outdoors and just want to paint with the primer as is.
Asked by: Joey
Primer coatings are not stain resistant. You should always paint over a primer - I recommend the highest gloss paint available because it is the most durable and easiest to clean.
