Hey guys/gals I know I should probably post this over on Painttalk.com, but, I believe there are enough experts here to help me with this question.
Customer currently has 2 coats of UGL Drylock on her basement walls. She wants to freshen it up with another coat of Drylock. My question is: Should I use Drylock or would I be ok using a flat white latex to match the flat look of the current Drylock on the concrete block?
I should mention that there has been a small amount of moisture migrating through the walls near the bottom which has left barely noticeable stains. There hasn't been enough moisture to even leave the floor wet, just enough to discolor the block.
The original DryLock was the expanding masory sealing (not ceiling) paint and only meant for the first coat. It's kinda pointless to put a second coat on if you first coat was sound, but now they make standard paint as well so the "Drylock" name of paint can be put over the old with no problems but all you need is the regular paint. Water stains will need to be primed with a stain blocking primer or they will bleed through the paint. The source of the moisture needs to be addressed as well.
Latex Primer: Good for Drywall, that's about it.
Behr Paint: The plastic buckets are good, that's about it.
