Putty and paint advice for sash windows

[markturner]

I know several threads exist on here and have looked at most. I have a specific query regarding the sashes I am currently making and installing. They were glazed using trad putty 2 weeks ago, stored in the house & workshop for painting. I am told by the glazer we can paint after 2 weeks, but the putty is still pretty soft and you have to be very careful not to deform it when brushing....its not dragging though.

I am under a fair bit of pressure from teh client to install the sashes ( frames already fitted and windows blocked off with OSB) but we wanted to hold off and paint the sashes on the bench before fitting as its easier to get a better job that way and we dont have to battle the weather.

If we do end up having to install the sashes with the putty ( we have painted the wood) unpainted, will this cause any issues to teh putty's drying process or give problems down the line? Thinking maybe fit the sashes and pop them out again when teh putty is drier....?

Using ( at clients insistence) Farrow and ball water based exterior paint.

Thanks

Linseed putty hardens with oxygen so increasing air flow around the putty might increase the hardening rate somewhat.

As said air flow will help, a fan blowing over them should speed things up.

Water based paint and linseed oil putty don't always play well together.........

I painted some trad putty almost immediately in the summer and it was too early so the paint cracked and flaked off, however a few months later a light sand and touchup on the putty and it all was good. Offer fair warning to the client that you can install sooner with the risk of some future touch-ups.

Only to add that I have used water based F&B exterior eggshell very successfully with trad putty, but yes, I did have the luxury of leaving the putty to cure. I resolved to not use trad putty on my future projects for this reason.

Pull out the putty and replace with a hybrid polymer, paintable next day.

Did you dust the putty properly with whiting or plaster ? Sounds like the putty may have been too oily to begin with.
I suspect you might need a really good adhesion primer under the farrow and balls waterbased, I recommend Tikurilla Otex or maybe Zinsser.

I never use putty anymore, its only advantage is price.
