What paint?

ILIKEFOOD

Hi Folk

All my internal doors need to be repainted. Here is what I am dealing with

Doors were varnished pine.. previous owner painted with what I think is a satin oli based (guessing) paint. No blocker was used as far as I can tell because the various knots and wood reisin seem to have come through (all though with the orginal varnish I'm not sure how that happened).

The current top coat is flaking like mad in places. I think it was a water based paint, although some of it comes off very easily..some not so.. I might be dealing with two kinds of paint here…

Once I get as much off as possible what type of paint should I be using? Should I use some kind of stain blocker undercoat first?

And the final coat? an oil based one?

I also need to paint the new skirting and architraves which are mdf primed with an water based primer.

Thanks for your advice in advance.

Head out and buy a good quality detail sander if your going to be a few weeks, otherwise rent one if you will get them all sanded over a weekend, will need to give all doors a really really good sanding to get them back to a sound surface, easier again if you can take doors off and lay them on top of two sawhorses, saves the back and knees when sanding.

Recoat the whole door in a shellac based primer, will act as a primer for any knots etc and will give excellent adhesion over whatever is currently used as paint on the door, then apply two coats of a good quality acrylic satin finish.

For the water based primer, 123 primer is an excellent option, ralston all prime or colourtrend prime are also very very good.
