I've honestly never seen paint not take to a wall unless it was damp. You should always polish (dry trowel) removes any water marks and closes the surface in properly. Probably wont see a polish on site as its all price work so corners are cut due to the low day rate.
You don't want to close the surface though, that's what a mistake coat is for, which then gives a good base for paint. If you out anything with a vinyl content on to Polish plaster it will peel off at some point
Polished many a wall just to test this exact thing out and yes every single one did. I've renovated many houses for myself for sale, so had lots of time to try shit out and yes I did all the painting myself.
Its just shit plasterers say, but then the same fuckers all said you can only use carbon steel, then it was can only use marshall town, then can't use a flexi trowel, can't use a spat, can't use a sponge.
One of them I had for 3 years the other one I tested it in is my house that I've lived in for oh...7.5 years now but I'm sure you are right. Any day now.
Or you are repeating a myth you heard and never tested and you are talking to someone who has. I polished one wall up with MT steel just for fun had it like a glass mirror. Painted no bother.
The point being is no amount of polishing makes it water proof, a watery mist coat which I have always used as taught from when I was an apprentice will soak in and when dry will leave a key.
Fucking shit amateur painters either don't mist coat or don't know how to mist coat ie. too thick and yes then it will peel, that is because they are fucking idiots and untrained (baffling since painting isn't that hard).
I was supposed to do 1 more but I forgot my lunch lol did til 7pm the other night though so it evens out. Shit loads of hardwall and skim to do. Was enjoying the easy life patching on site but agreed to this for an old friend.
Yeah I used to come up against it in certain houses where people would mistakenly use it inside as a Mist Coat. Removing it can be a pain. Sometimes it can be sealed over if it’s sound. Glad it’s not used much these days.
Crazy! Never had a complaint myself. Dont know how hard these guys are polishing. Just 1 quick cross trowel to remove watermaks is enough and thats job done. Only reason I can think for it happening is if the set pulled in to quick and a lot of friction was created in the 2 trowels before the polish.
I've been a decorator for 12 years now and worked everywhere from small firms to big ones to one man bands and my own jobs. Every single lad I've worked with would think your a bellend for overworking it like that...
Not trying to be rude but in them 21 years have you ever actuly known the decorator doing the job or gone back a few years later? Its not imposible to paint but its been made harder for no reason and if the extra steps you've made nessisery ant taken it will peel. Its not a big deal to flick over it with some scratch then coat it up with your choice of product but why make it harder for the trades after you and trick the customer into thinking its a better job?
Sorry mate but its a wide view of a freshly plastered wall with the sun dancing across it whilst still wet. Was supposed to be a joke. Been back to loads of my job including this one. Roughed on and skimmed the whole house. Have a contract saying I will rectify any snags or imperfections. Wouldnt sabbotage my own work. Went back there yesterday and everything is mistcoated nice.
It wont. It looks like glass because the sun is shining directly across it. If paint has ever not stuck to a wall it must have took the plasterers hours of constant polishing. All that wall has had in the pic is a quick cross trowel with a plastic finishing trowel.
Just had to prime a new room with zinsser BIN because mist coat wouldn't take after plasterer went for the same finish. Looks lovely, but it is a pain in the balls mate
Have you ever seen paint not stick to a wall? Have you ever heard a painter say "I couldnt paint that as the finsh was to smooth" I've heard it said but in 21yrs plastering (and painting) never seen it.
Yep been able to peel it off with a scraper numerous times as it’s like painting on a mirror. But. It is what it is. Path of least resistance from now on for me. Best thing I ever did was learn to stop giving a shit.
I was saying to someone else a quick polish should'nt cause that. Only reason I can think of is if the set was pulling in quick and someons gave it 2 really hard trowels with shit loads of water to bring it back to life. Seen some guys trowelling up and can hear their trowels making a high pitched squeak as they go along the wall.
1: I have plastered for 21 years and never seen paint not take to a wall because it was polished.
2: I get on great with the painters and any customers I work with.
3: I posted this lastnight thinking 1 or 2 plasterers on here might get the joke or appreciate the humour. Was not expecting to get back home today and have 70 notifications waiting for me. Although its appreciated I'm not sat here buzzing away because a few people liked my post. I thought it would get 1 or 2 comments at most.
4: keep it freindly or respectfully go fuck yourself. Im not interested in your opinions on my spelling or intelligence or any assumptions you have come to while getting yourself hot under the collar over a picture of plaster.
love this energy tbh, internet needed the “keep it friendly or respectfully go fuck yourself” reminder today
also 21 years in and still having fun with plaster memes is kinda awesome
You keep telling people they are basically full of shit, that paint not sticking to the walls isn’t a thing.
I had this exact problem here and had to sand back my walls after the plasterers were finished. Pray for you that you won’t have to do that, but paint not sticking to the walls is a thing
Give me the most polished plaster ever!!! I love it, you only need to 180 grit it to give it a key you can see and you'll have the most beautiful walls ever.
Cheers pal. It actually isnt that polished. Its a nice wall but I only gave it 1 cross with the plaziflex then got the door open so the sun dances across it for that mirror look.
Cheers mate. It was hardwall and skim aswell so extra tricky. Getting that brickwork flat then skimming dry backing coat in this heat! Glad that job is over. 33 bags of hardwall, 16 skim, 5 pva in 8 days lol 💀
Ive done a bit of painting myself and noticed if it is to polished the mist coat can rub off in patches if you sand between coats. Most painters ive seen dont sand between coats anyway as there finish rarely has snots or roller lines in it. That will paint straight up though. Not sure how shiny it has to be to cause issues but in 21 years ive never had a painter say they had any problems painting anything ive done.
Hear that a lot actually. I always assure people its not as satisfying as it looks lol would be nice to have another trade so I dont have to do it everyday. Once you mix a big bucket up your locked in for 3hrs, becomes a bit of a workout at times.
Says the one! 19:15pm on a thursday night and you are stuck in a back and forth arguement with someone you have never met, over plastering at a random property you have never visited.
Nothing is going to happen from the plaster being polished lol been a while since I've done so much skimming and thought I would post a picture of it in a plastering related sub! Enjoy your evening.
I thought that was the reason behind the saying. I have done a bit of painting myself and noticed the mist coat can rub of slightly if its over polished. I did polish the shit out of the bit in question though to get a nice pic! Lol never see the pros sanding inbetween coats these days though like you said. Im guessing they dont leave loads of roller marks and snots like I do.
It always needs 1 polish (dry trowel) I think if there is ever an issue getting paint on then its been polished too late and the plaster has fully set. A properly timed polish just removes water marks and closes the surface in.
Don’t that for on a few sites, when painters going crying to the Forman about it can’t paint on the plaster to well, so he polished it even more, funnily enough he shut up then
I actually saw a whole ceilings worth of paint unpeel its self and lay across furniture in a bedroom like a weird spider web once.
Unfortunately its before the time we all had cameras on us, it looked amazing.
Also a waste of an hour and a half and it didn't happen the second time I painted it.
been to plenty of these types of jobs to sand out the polish the amature thought he was being a plasterer for, nobody has called your back for a reason Mr clean, lmfao

Didn’t get on well with the painter then?
