Painting varnished doors

ally1974

Hello

I'm having trouble with some previously varnished doors which I'm painting white. I prepped properly, or so I thought, sanding, primer and undercoat but with two coats of satin I'm still getting streaks of yellow coming through!


I've checked up advice about using aluminium based undercoats or a chalk paint (not keen on the finish and too expensive in my view for what it is, maybe I'm just not trendy enough!) but not sure what is best. Any advice? I was thinking I might slap an oil based gloss on top just to see what happens!


Thanks for any help you can give!

Never had any issues to be honest and all 14 internal doors in my present house were stained/varnished pine.
Now white. Lightly rubbed down, undercoated once with oil based primer and gloss coated once and the result?, perfect, but, as with all modern dumbed down oil based white, within a couple of years those not in sunlight wwhere creamier than cream.
Tried several water based paints from the sheds, yuckky yuck, awful to apply and get a finish but stayed white.
Someone then put me onto Johnstones paint aqua I think it's called, a dream to use, great finish and it stays white. I undercoat, 1 top.

Maybe not the answer you wanted, but I have to say that at no time did I get any show through as you have experienced.
What would I do? i coat oil based undercoat, then the paint mentioned above.

Thanks Cyclonebri1- I did question whether to use an oil based undercoat round about the time I put the 1st top coat on!!

As CB1 says. Oil based undercoat will seal everything in then top coat with whatever finish you want. Depending on the finish of the undercoat, and how long you let it dry, you may need to scotch pad the surface to provide a good key or allow emulsion (yuk!) to stick and dry properly.

cyclonebri1- Did you use the gloss version of the Johnstones paint? How long has it been up and is it still white?

Phil, most was done 2 years ago, but I left a few areas ie walkin wardrobe, utility room etc. I finished the rest this winter.
When I painted up to the 2 year old stuff I thought Oh, it's faded a bit, but no, once dried it's exactly the same shade.

Yes I did uses the gloss version and it is a true gloss. You do have to work quickly but this stuff is way more forgiving than the shed brands and flattens well before drying. Provided you can work to a wet edge it's easy to use, probably all good as oil based but without the cleaning issues.

The 1 thing I was worried about was it's resistance to damage, we have 6 grandkids under 8 and it's standing up well to the inevitable knocks.

Good to know. I may give it a try in my spare room when I come to do it next winter and see how I like it.
