Is it ok to gloss/ satinwood paint over existing gloss/ satinwood paint

[raymonReddingtonsOtherdaughter]

I’m serious. I loathe having to undercoat, can I just paint over existing paint? or is that a terrible idea.

I have no choice but to paint/ decorate myself, but I’d almost rather not do it, than do two coats, so I will choose one coat emulsions etc, but what about gloss/ satinwood.

Really getting myself in a dilemma over it...( I know it’s not a major issue to anyone, but it’s my immediate issue of the day)
Advice appreciated

I feel your pain op, painting woodwork is so boring.
I'd give it a good sand first and then use a one coat paint.
I hate gloss personally, satinwood is easier and looks nicer.

Gloss on gloss often ends bady. You may get away with it if you give it a really good sand back so it has a good key, but If it were me I'd key it up, give it a coat of undercoat, and then gloss it. Much more likely to get a good result that way.

Anything over gloss often ends badly. I had to repaint the walls in the bedroom and living room and it turned out the previous owners had patched up the matt magnolia paint with gloss magnolia paint.

I'm still cursing them three years later.

Buy paint that doesn't need an undercoat.

Solvent-based satin finish formulation that is tough, hardwearing and dirt resistant. Does not require an undercoat except where a strong colour change is required. Suitable for use on interior wood and metal surfaces.

If you sand and use sugar soap and then a decent one coat paint it should be fine, just be careful of drips. We did this and it looks fine.

Oh.....sanding it all is almost as bad as undercoating !!

I think I will use satinwood, as opposed to gloss.

Wondering if I give the woodwork a good rub ( a bit of a rub really) with some sugar spray stuff, that would do, and then satinwood ontop ...

Ah my paint sample book thingy says no undercoat for satinwood once ...😀 but it says it will take 24 hours to dry.🙁
There is a quick dry satin, dry within 2 hours and you can wash the brushes with water...but the lack of mention of undercoat, suggests this needs it....

What everyone else said.

I tried shortcutting this once, gave the gloss a violent scrub with sugar soap and then glossed over it without sanding or undercoat.

Huge mistake ... the new gloss didn't adhere properly and big flakes came off if touched or bumped. Put up with it for a year then scraped the top coat off, a horrid job, then sanded and under coated properly, recoated properly, blah blah.

Never again will I scrimp on prep, it was a boring lesson to learn :(

And thank you for the advice...sugar soap ( avoiding sanding unless extremely necessary ) and a one coat satinwood.
But I’ll have to be really careful when the kids get home, so they don’t touch it at all.

My brother once tried to emulsion over a kitchen wall that my grandmother had totally glossed. It was horrific, he had to use an electric sander to clean the whole thing off, as it melted, or seemed to melt.
I’m just feeling too old and lazy to undercoat, I didn’t mind in my teens, but I don’t fancy it at all now...

If you don't give it a good rub down it will just peel away. It can't stick to a smooth surface so it's either undercoat or sanding.

Oh read the last post, and worried ...but maybe the once satin which says no undercoat will work.

Drat sand too ..looks like the way forward. A friend suggested Wilkinson’s as being the cheapest, so I will look there before B&Q and Homebase

Also sugar soap will do sweet FA. It's for cleaning the grease away, nothing more. You dont have to take it back to bare just rough it up.

It won't. The reason you undercoat generally is to block out the previous colour. It isn't supposed to replace sanding that's just a handy plus. Once coat is thicker that's all. It also has the downside of being oil based and will yellow like fuck

Don’t do it without preparation!!

A cowboy decorator ruined my hallway by not prepping. It’s cost me a fortune correcting his shit!

Try painting with BIN (google it) which means you can then paint over it. I love BIN and wish I'd known about it years ago.

You only need to sand it lightly. It would take 15 minutes tops for an average size living room.
Sugar soap it before sanding and use satin.
Maybe postpone doing it until you're in the mood to do it properly.

Mrsharrison, I may never be in that mood.....and oh will it yellow ?

I will google BIN, and bear in mind the sugar soap isn’t the same as sanding
Thanks 😀

Heart dropped at BIN.... primer...but shellac, is that a clear liquid stuff? I think the undercoat thing is I don’t want to have super attention for detail twice over on the gloss ( lazy ) once will be more than enough.
If this was a clear paint, it might be better. Off to google shellac now !

Ginghamstarfish, is the BIN stuff clear ( I’m hoping) , then I might consider an undercoat, and then can use quick dry gloss ! Ooo so much better, if it is .

I would avoid one coat like the plague, sorry! We used it on some doors and skirting (over undercoat/primer) and you only have to look at it for it to come off.

We had new carpet put down in one room where we'd used it and had to repaint the skirting because half the paint had been scraped off in the process of putting the carpet down. Carpet fitter said it happens a lot.

Good clean, undercoat/primer/BIN, two coats of quick-drying satinwood.

Sorry.

As to yellowing, it will go yellow if you use oil based paint. It will rub off if you do not use oil based paint. In my experience neither issue has anything to do with whether you use one coat paint. Woodwork needs repainting fairly regularly (every 5 years in our house) due to it going yellow or rubbing off, depending on which type of paint you use. Either way you must sand!

Sand the gloss, and wash all woodwork with sugar soap solution before you paint.
Use quick drying paint. I would use undercoat.

Wilko is very good on prices.

You might get away with using steel wool or a wire brush instead of the sanding.
it is probably not the best time of year for painting.

Use a self priming paint like zinnser permawhite. Comes in gloss and silk. good paint that sticks to anything.

We sanded all our woodwork thoroughly, and it still took 3 coats of paint to cover up the colour. TBF we were going from sandy brown to cream.

Ive bought some sandpaper...and a block..! ( I might have bought one coat satinwood) ...just couldn’t face undercoat.

But I’m starting on the downstairs WC, well toilet to me, so although there’s a good bit of woodwork to do, if I’m not happy with the result it’s onIy a small room.

I will try the BIN ( now I’ve heard of it) and quick dry satinwood when I embark on the stairs and landing.

I will be able to banish everyone from the downstairs loo until all the paint dries, so that is lucky.

I realise it’s the wrong time of year, so can’t paint the front door, which will last until the spring/ summer ( the paintwork is ok, it just needs a repaint and new brass letterbox)
Thank you for all the good suggestions.
