Painting walls - weird texture

[mandybeesborough]

Painted newly plastered walls in 1970’s house.

Left plaster to dry for over a week.
Painted with no nonsense trade plaster bare x2 coats as per instructions.
Then painted with Dulux trade Jasmine White
X 2.
I now have a weird texture on the wall.
Used decent mid pile roller for all.

Any way to remedy?

Also just to add I’ve done a very fine sand of the walls before putting on the jasmine white.

I’m no DIY expert, but I’m having a few walls plastered in the coming weeks and was told that it had to be left to cure for 3 weeks before painting. I could be wrong though! Hopefully someone else will have better advice

Yes I was told a week but could be a case of painting too soon and I should have waited 3 weeks. I guess it still leaves me with the same question though - can I remedy it and if so, how?

Leave it for the 3 weeks, sand it down and paint it again.

Thanks - So it’s been 3 weeks at least since the skim was done now. Do you mean 3 weeks since the last coat of Jasmine White?

Just looking at my ceiling, which wasn’t plastered but was painted with Dulux trade white and can notice a similar effect. Now wondering if it’s the way I’m applying it. Done other walls and ceilings fine though 🤔

Did you use a fluffy roller? I used one in my bathroom and the texture looks similar to yours. I was using a thick gloopy paint especially for bathrooms (Dulux) and I was quite disappointed with the finish.

Did you prime the raw plaster with a mix of paint and water first? I suspect the plaster is still drying out and the final coat has sealed it and the moistures is seeping through in places. Nothing much you can do except leave it to dry out for a few weeks. Stand it down and paint another coat of Jasmine over it.

My last plasterer primed everything with watered down PVA (about 30% PVA, rest water). Paint went on three days later, no problems.

I used the no nonsense plaster bare (I think that’s what it’s called). It’s like a ready mixed mist coat. I was worried about getting the right mix if I did it myself. It had decent reviews.

Sorry OP I see that you did prime it and also used a roller. . Could be that you spread the paint too thinly or that the skim had not dried out sufficiently. How about contacting Dulux customer service and see what they say.

Looks like the wrong type of roller (too thick a pile) and the paint was applied too thickly. Also, you say you sanded the wall - did you wash it down and allow to dry before applying the paint? Dust can leave a weird texture on the wall when painted.

Best option is to get a decorator round and get them to use a dustless system (Mirka / Festool) to sand that right back and start again.

Rub it down, give it a coat of Bullseye 123, then repaint.

I strongly disagree with putting glue on a surface you hope to paint.

Mist coat of emulsion with water is the correct treatment for bare plaster.

-pigletjohn- totally agree with you there. PVA used to be the way people sealed plaster but it is totally wrong and you’re in danger of the paint all peeling off the wall (as happened to an old neighbour of mine). Always mist coat and then paint proper.

That looks like the roller to me. Wrong type of roller and paint applied too thickly

I'd say roller too. Although I don't dislike the texture! Completely flat walls tend to show up any imperfection.

We had a whole painted in Dulux Matt white in January and had exactly the same problem and once dry if clothing brushed up against it, it left a small powdery residue. We sanded and repainted with Wickes professional white silk. It solved the problem and is now smooth.

Was it that texture instantly? If so I'd say it's probably down to the way it was applied rather than applying too soon.

I've often got more texture than I'd like, despite trying all different rollers and assumed I was applying the paint too thickly or not rolling with the optimum pressure. I think a great finish comes with experience!

Looks like the roller and too thickly applied paint. Probably have to sand it down and start again.

I had exactly the same thing happen to me on a ceiling. Couldn't get a good finish despite doing it twice. I decided to ignore it as I couldn't stand to paint it a 3rd time.
