Hello,

Zinsser states that their mold killing primer is only for non porous surfaces. I am curious if I can use this on plywood/2x4 surface that has mold?

Or do I need to seal the wood first and then use the mold killing primer? I am a little confused because I see this being used on drywall which I thought is porous...

Thanks

Thanks. I will plan to use their Bulls Eye 123 primer that seems to be OK for porous surfaces like wood. I presume having primer that is resistant to mold is not a bad idea after cleaning the mold?

Hmmm. A primer than can't be used on porous surfaces like bare wood, drywall and joint compound. Sounds like a lawn mower that's not to be used outdoors.

Does Zinsser have a 1-800 Customer Service phone number anywhere on that can?

If I were you, I'd leave that Mold Killing Primer on the shelf in the store and clean your wood with bleach diluted with 5 parts water. Then rinse the wood down with clean water, allow time to dry and use a NORMAL primer on that wood. That is, a primer that's meant for surfaces that need to be primed.

Yep, used Concrobium to kill what's there. I had done this last year but it seems like they came back even with only 65% humidity and under 60F temp. I will clean up the area use primer/sealant.
