Paint

I have a few interior doors that could do with a fresh coat of paint. They were last painted ( about 10 years ago ) with oil based gloss paint..

Can satinwood gloss be used this time and do they have to be undercoated.

Thanks.

Oil based Satinwood will work ok with no undercoat .

Water based satinwood will need an undercoat .

Give them a rub down with sanding pads to take the shine off the gloss .

If you go down the oil based satinwood route dulux is probably the best brand to get .

In water based colour trend is the best imo.

Due to the fact that they have previous been painted with oil based gloss, they will need to be undercoated before applying the finish coat whether you use a Satin or gloss finish, using oil based finish isn't going to help it adhere any better than waterbased.

To add if you're repainting them white, I'd recommend using oil based as waterbased gloss or Satinwood looks shite imo.

is oil based paints yellowing over time still an issue?

Historically oil based gloss would always yellow over time, with satinwood it was less of an issue. For the most part over the last 10/15 years nobody is putting on a gloss finish internally, save for a very few people. That would be my experience anyway

Oil based satinwood is self undercoating , it doesn't need a separate undercoat if going on top of oil based gloss .

Rubbed down with a sponge sanding pad to take the shine off the gloss and then 2 coats of oil satinwood would be fine,

1 coat of satinwood would still work ok but it will yellow quicker .

I was taught old school many year's ago, and that the process I still use today, hard to teach an dog new tricks🤣

There are a few reasons I continue to do it that way, 1, u/coat is usually cheaper to buy, (you can pick up 5ltr of Armstead u/c for less than €50) 5ltr Dulux satinwood is approx €75, 2, covers better, 3 drys faster, 4, adhere better imo, 5, you don't have to sand the shine of the gloss before painting. 6, better finish imo.

Of course 4 and 6 are subjective but my opinion counts in my head.

But each to there own I guess

I know our houses (new builds) had oil based interior.paint on woodwork and it yellowed, we had ours repainted when we moved in so didn't affect us but everyone else had an issue with yellowing

jack of all

I would never repaint a previously painted door without using an undercoat- as already advised by previous poster. In addition to giving a perfect base for satinwood finish coat, it helps to fill in and even out any old blemishes, chips, dents and other imperfections. I would still prefer an oil-based satinwood but I've used Colortrend water based on furniture with great results too. I've seen plenty of paint jobs where people have skimped by not not rubbing down properly and undercoating, doesn't make sense to me.

Thanks for all the advice above folks.

I have eight doors (front and back) plus architrave.. How many LTRs of undercoat and finish should I need approx.

Tks again...

2.5 litres of each will see you out the gap. Adding a couple of cap fulls of white spirits to both when you're doing it will also help spread the paint a little bit easier and reduce the risk of runs or sagging.(if you're using oil based paint) Oh and get a good quality paint brush.
