Re-Painting wooden interior doors

andre_xs

Hi,
we wanted to paint our interior doors, doorframes (metal), stairs, handrail, etc. This is all already painted with some old paint.
We went to I think Wickes or Homebase or so, and they recommended a good paint (some well-known brand).
I sanded everything with fine sanding paper. Not so much that the old paint came down completely, but just so that the surface gets "rough".
However, the paint doesn't stick very well. It easily peels off if you bump into it with something slightly harder (e.g. a plastic box or so).
Now I was looking for some different paint and saw that most paints require a primer for these purposes (which the guys at the market didn't mention...).

My questions are:
- Do you have recommendations for a good primer?
- What about e.g. Dulux Quickdry Satinwood, they claim they have the primer/undercoat integrated and don't need an extra priming coat

And most important:
- For the new coat to stick, could I just again slightly sand the doors I already painted, prime, and paint again? Would the new coat provide a tough enough surface to prevent flaking? Or would I need to sand down my first paint (the one without primer) completely? (I hope not the latter,this would be a lot of work and dust, I applied three thick coats...)

Best wishes,
Andre

Folks on here often recommend Zinnser Bin. Not used it myself but I haven't read of any complaints from those who use it. For wood that is already painted, rub down (as you have done) and use an undercoat, allow to dry and follow it with a finishing coat. Do not mix oil-based and water-based undercoat/top coat.

I run a property maintenance company. People at B & Q and the like are employed to sell you things. And sell you things, they will at any cost! They are not trade professionals. Here is what you should be doing.


1) Clean everything down with Sugarsoap (available from supermarkets, Wilkinsons etc)
2) Key everything with a medium grade sand paper.
3) Clean everything down with methylated spirit (NOT white spirit) to get rid of all the dust
4) Apply a coat of a SOLVENT based undercoat. Avoid the 'low odour' and 'quick drying' undercoats - these are water based.
5) Do number 4 again after 24 hours.
6) Apply a coat of SOLVENT based satinwood or eggshell (Not white gloss as it will yellow in 6 months)

Thanks phill99,
as a professional, do you have recommendations for good quality undercoat (white) and colour (white) which are solvent based? If possible not too expensive, we're a bit short of money and need to paint quite a lot...

There are so many paints out there, hard to find its way through all of it...

It is false economy to buy cheap paints You require more coats so it requires more paint!!


Get a decent branded paint - Dulux, Crown, Johnstones, Leyland, Macphersons.
