Priming over Pretreatment

Postby bjwhite » Sun Aug 09, 2015 11:03 am

I'm restoring all my wooden shutters and will be using a penetrol/turpentine pre-treatment on the punky wood before priming. I'm trying to do this in an assembly line fashion. I've finished the scraping, sanding and repairs and am ready for the pre-treatment. I'd like to do all the pre-treatment first, then all the priming. You recommend priming over COR when it is 80% dry. What happens if it is completely dry? I know in the past you've said it may cause adhesion problems with the primer, but are there primers on the market that work better now?

The "80% dry" gives somewhat better primer adhesion, but you should get average adhesion if it goes past 80%.

Use an oil-based alkyd resin primer made by the same company that makes your selected top coat paint.
