Can I paint matt satin over gloss interior doors?

[kissmelittleass]

I hate the gloss doors they've gone off white yellow!!! I recently had a painter in before lockdown who basically didn't want to do it he said it would cost a lot to do all the doors downstairs ( 7 doors) so I'm going to attempt it!! Or at least going to try!!
So has anyone done this?how do I prepare doors? Was the finished outcome good?
Any tips welcome

We used Zinsser BIN on our old woodwork. We sanded out the larger lumps and bumps, cleaned with sugar soap, painted a coat of zinsser then two coats of dulux satinwood.

Completely agree with slewts you need Zinsser BIN 1-2-3 which is the water based primer and stain blocker. It sticks to anything including previously glossed surfaces. You can get it from B&Q, Screwfix or Toolstation but check stock as there seems to be a shortage where I am.

If you want to you can give a very light sand, shouldn't take any time at all. Clean with sugar soap, rinse and dry. Paint your primer on, then your matt satin. I am surprised your decorator said it was hard, it isn't hard, just time consuming but there is no real need for sanding with Zinsser.

This is the product, have a look at the reviews, also the reviews on Screwfix too. There is another Zinsser BIN but that is oil based, I use this one as it drys super fast.

Great tips thank you both so much!!

Just a quick way does it have to be sugar soap? Or would just water with washing liquid do?

Sugar soap is better than washing up liquid.

Buy the powder sugar soap. Wilko and DIY places should stock it. Follow the instructions, and start at the bottom.

You would probably get away without using a primer, if you sand the door well. You get much better results if you paint a flat surface.

Satin is less durable than gloss. I'd paint them in non-yellowing gloss.

Yes I wouldn’t see the need for zinser bin in this situation- it’s really expensive and is more of a stain blocking/sealing primer. It’s amazing stuff but to do 7 doors is overkill. Normal primer on a well rubbed down surface after sugar soap should be fine. Just finished an almost identical job, lots of doors with 40 yr old gloss and it looked great.

And use a roller - a smooth one!

I’ve just done mine and I did say door A front, door B front, back to door A for a second coat and back of B

I did ‘one’ or two doors a day over the week so it didn’t feel rushed

We did all our gloss woodwork about 5 years ago. We sugar soaped then primed with a white wood primer and then white satinwood over the top. It took well, although over the last 12 months any knocks to the wood and the satin has chipped off showing the old yellowed gloss.

I follow an excellent Instagram account that is run by a woman who owns a paint shop. Honestly.. she makes it so interesting! carlowpainthub

We painted over our white gloss doors (which had gone yellow-ish) with b and q own matt white. They needed two coats but the finish is perfect. Didn't prime or sand them

Thanks for all the tips! I did one door today sanded door down, sugar soaped and dried door then started painting few hours later.
I gave door two coats but I can see brush strokes! Should I redo again with a mini roller?
Door looks good otherwise the glossy shiny look has gone off it.

If you have brush marks there are a number of reasons:

Cheap brush,

Technique, search laying off, basically straight after painting a section, whilst it's still wet, with the paint brush clear of most of the paint, run down the length of the grain to flatten the paint. Also, don't go over sections once they're drying tacky, cos it will ruin the finish. Paint flattens as it drys. Alternatively, use a foam roller.

@Zandana123 great I've got a foam mini roller for the doors, will take your tips on board
