Pinholes after first coat of Drylok ?
I just started the basement and did the first coat of latex Drylok. This is going onto cast high pressure concrete walls. Coverage works out about 50 sq ft / gallon. Yes, I am putting it on like it's free with a 6 inch brush !
The issue I have, is that now the first coat has dried, I see LOTS of small holes in the wall that were originally air bubbles against the casting barrier. The Drylok goes over these, but does not form a solid membrane when it dries. The Drylok surface tension is too high it seems, as it breaks round the hole during drying leaving hundreds of small holes.
I am hoping the second coat will cover the holes, but I am afraid it will not. Any suggestions other than using a cement filler on the wall to fill all the holes first and then another few hundred dollars for more Drylok ?
OBTW, I bought a paint sprayer that said it would do Latex... it could not even suck the Drylock out of the container !
