Rain halfway through painting exterior window frames - what should I do?

[Bobby82]

I've sanded and filled my exterior window frames. Managed to get one coat of Dulux Weathershield primer on them, and then two hours later it started raining. Looks like it'll rain on and off for the next week or so, what should I do?

1. Try and get a coat of weathershield undercoat on in breaks between showers, with the risk that it won't have time to dry, or the primer won't be fully dry when I do it
2. Wait until next weekend, when there are three sunny days forecast

Also, will I now need to repaint the primer?

Thanks!

It'll be alright. Just observe the drying times on the tin and go for it if you've got a weather window.

Don't forget to lightly rub down between coats.

As long as you don't paint over a wet or damp surface, it will be ok.
