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.........
