Primer advice

[Bucks]

Cheers opps,
I will have another go with the Floetrol again when I have a bit more time to experiment, especially the Primer/Undercoat.

At the moment on these doors I will continue without the Floetrol, as it seems to be working better without especially the Satinwood.

After quite a bit of experimenting, I find that thinning the Satinwood with 50% water & the Primer/Undercoat with 40% water seems to work best.

Any tips of the trade for filling small hairline cracks in the paintwork, before I spray the Satinwood on?

There are a number of fine surface fillers out there, be careful though as some are a pig to sand back.

Epoxy resin filler would be the best option if the doors have not been painted yet. If you have already coated them it is likely that you will end up sanding through your new paint.

I use red devil one time but on very fine hairline cracks it is difficult to sand back with out pulling the filler back out, thus you need a fine paper, eg 400g silicone carbide.

One of the downsides of spraying is that it has no gap filling properties. You might get away with brushing the paint over small gaps, it might even suffice for some of the hairline cracks.

Up to now I have just applied the primer/undercoat, so will try the epoxy resin (that is what we have been using on any other filling we have done)

After sanding, If needed I will touch up with a bit of B-I-N as there are a couple of rails that the primer/undercoat is not taking to (a bit to resinous I think) so I will also touch those up with a bit of B-I-N.

Do's this sound OK?

EDIT: Sorry its not epoxy resin that we have been using its 2 part polyester filler

That is what I mean by epoxy resin filler.

What do you mean when you say that the acrylic primer is not taking?

It was only on one small rail on two of the doors.
The paint just wasn't covering, it was almost as if it was running of these pieces, it was a darker piece of wood & looked very resinous to me, the first door I sprayed a bit of B-I-N on & it was fine.
