Oil paint

[whatsreallygoingon]

I used some OB1 last weekend where I had some cracks between windowsill and wall (and did quite well with the application, given it was my first time as a homeowner. Pat on the back for me!)

I, potentially foolishly, painted over it with oil based paint. I did this because the sill's are painted in oil, but I'm still not sure it was a wise move.

72 hours on - the paint still hasn't dried/cured correctly. Certain bits are sticky to touch and do leave a little bit on my finger, if I touch.

Is this just going to need some patience - don't touch and check in a week, for example? or have I completely messed up here?

It was two coats (again, maybe overkill) and, as someone not experienced with painting, I may have applied a little thick - for context.

Thanks!

The paint will "never" dry. Just hit it with water based primer. Then recoat with oil based paint.

OB1 is a MS polymer. I have painted MS polymers a year after they were applied. The oil based paint would still not cure. I do not understand the chemical reaction.

I have come across a brand which required two coats of water based primer (from memory the product was called the Dogs *******s- or something like that).

Don't worry about the fact that the oil based paint is still slightly tacky. The above definitely works. I am a decorator.

Cheers. Two questions, if I may (one of which is likely stupid, so please accept my apology!)

1) any particular water based primer you'd recommend? I do actually have a 'Leyland acrylic primer undercoat', if that would do the job? (this one)

2) after applying the above - would there be any benefit to using a water based paint over that, or should I just stick with oil, given where I'm up to?
