Hi there,

The company I paint for does a lot of heritage restoration and currently
is exclusively using alkyd paint for our products. *However, we'd like to
start using more latex for drying time, environmental and health reasons
etc.. The problem is that with the oil-based DAP window putty we use; I've
read it's ok to paint latex over it after waiting for it to dry, but I
don't think our customers really want to wait that long (and many don't
want to do it themselves or have to pay a painter when it does set up). *I
wanted to try/suggest doing the entire sash/storm in latex with latex
primer and finish, bed the glass and ONLY paint the putty with an alkyd
colour match. *

My question is: how important is it that paint overlap where the putty
meets the wood? Will water penetrate that seal and damage the putty
faster? *

I just posted a reply but it didn't look like it went through. So if
I am double posting, I apologize in advance.

First off, check the Secretary's Standards to see if it's allowed.
That's pretty definitive and you'll do little to argue your way out of
that in any case.

Second, get some scrap and see if the sheen matches. You might match
the color but you'll also need to know if the finish is the same. Not
all "eggshell" is the same.

I hope this goes through better this time.

Pat.
