How to paint these wardrobe doors?

[Newdress93]

In my new house there's wall length fitted wardrobes, which I am keeping, with some wooden doors (photo attached).
I want white doors- how best to go about this ?
I imagine buying new cupboard doors would be very costly. Am I best to sand then paint (gloss), or use a wood primer then paint (gloss)?

I would use zinnisser paint on them as a primer then your paint ontop. That should stop the pine showing through. They would look lovely painted the same colour as your bedroom

I'd lightly sand then undercoat then paint with satin paint.

I'd also think about a different colour to white too.

Yep agreed with pp. A light sand, prime the undercoat then top coat.
Zinsser is high VOC, so I've recently switched to Bedec Allprime. Crown Fastflow is also worth considering. Both much much lower voc so a lot healthier, especially in a bedroom.

quick dry satinwood is often recommended instead of gloss these days. It's water soluble and resistant to yellowing. I use Dulux trade.

Prep is important so make sure the surface is really clean. I ended up scrubbing down well with sugar soap, then light sand, then wiping with white spirit when I did ours - but that may be OTT with the primer recommended above or just a better surface. Then one coat of primer, 2 of satinwood.

It's not OTT. It just means you'll get a high standard finish. No one wants a sloppy job. Prep is always the key to a professional finish.

As others have said - a light sand, then a primer and then topcoat. If you are set on white, then make sure topcoat is water-based and not oil-based.

I usually use oil-based as top-coat in any colour, but I will never use it for white as it ages/yellows quite fast. So I only use water-based for white paint.

It will seem like a faff doing the work yourself, but you’ll definitely save a lot of money by doing it rather than replacing. Would be lovely to see the end result when you’re done.

I wanted to avoid Sanding as I feel like the grooves would make it take ages, but it seems it might be the way to go !
I assume the only way of Sanding is by hand and sand each row?

I think it will take absolutely forever to paint them and will be hard to get paint into the grooves (especially where the panels meet the frame) without it going blobby.

If you definitely want them painted could you have them sprayed maybe?

Agree, spraying makes a lot of sense here!

Just coming on to say I think these will look absolutely gorgeous painted - I don't think it would take as long as you think

Personally I wouldn't go gloss. Maybe satinwood but I don't really like gloss finish on woodwork.

OP it's tempting to go straight to painting but if you paint something that is not well adhered to the door then it will flake off. I would take a green sponge scourer to it with some washing up liquid or sugar soap - really good scrub - then a light sand. I like site gloves, about £1.50 in Screwfix and make sandpaper much less unpleasant to hold. It won't take you long to rub over, you could prob do a few grooves at a time and don't fuss too much. Get white wood filler for any dings.

If the grooves are not too deep I reckon you could most of it with a mini roller. Maybe a small brush along the deepest point of each channel, then the mini roller horizontally along a few lines at a time. Be sparing with the paint or it"ll drip.

I like the bare wood myself. But I've just spent a week stripping gloss paint off woodwork with a heat gun, which may be affecting my judgement!

Eggshell can be used instead of satinwood. Might be slightly less durable (?) but easy to work with and maybe slightly more matte.

If the doors are varnished, a light sand and then a primer such as Zinsser would be fine. Look into short pile mini rollers for covering large areas like doors quicker - and easier to get a consistent coverage. Suggest eggshell or satin rather than gloss
