Matt white emulsion all patchy

lettywetty · 28 Jun 2020

Hi,

I am in the process of painting a few rooms all re-plastered.
Bought some Trade Leyland matt white emulsion.
Did undercoat with a mix 50% emulsion 50% water and all went very well. Next day 1st proper coat, no problem and then my 2nd coat ended up in a disaster. The walls against the light look all patchy, it is like each strike of roller has marked the walls.
Tried to have a 4th coat with a different roller, same.
Looks awful, like a kid has decorated the house. It is not transluscent, we cannot see the plaster any more butwe can see marks from the roller. Look almost like a textured paint at that stage.

What is due to?

How can I fix it?

Have done another wall re-plastered with a silk paint different colour and I had a nice finish. Is it just the way Matt paint is?

Thanks to tell me.
Letty

Happened to me a few times.
I came to the conclusion that it's a combination of paint and me not being a professional decorator.
My decorator fixed it in one coat and an hour.
Since then if I have to decorate I use dulux and never had a problem.
Professionals can use virtually any paint and get a nice finish.
Anyone can throw paint on walls, but few can decorate.
Like anything else it's an art.
Hats off to the decorators.

I usually buy cheap paint and have no issues. Decided to buy Dulux Diamond for the hallway as likely to get marked so can wipe, it's really patchy when daylight hits certain walls, gutted. The paint is really thick, but don't understand why this is patchy and cheaper paint isn't it. I'm not doing anything different.

Hello,
Thank you both for your answers.
You are right to say that it is very thick and I am going to dilute it a bit for a 3rd corrective coat. If it does not work, I think that I will use a mid-sheen over it. It's a disaster, I am bothered. I wanted to be trendy using matt, silly me.

Matt hides a lot of imperfections which will become very evident when painting in soft sheen or worse, silk

Johnny,
Yes, I read that somewhere but matt created the imperfections which were not there before. I ruined my walls which were perfectly smooth and flat. Now it looks like I applied paint with a trowel.
Would it be another way to correct it?
My main problem is in my corridor on the wall visible when we pass the entrance door when the light of the outside reflects on it, the other walls are not under the same light and there is no reflection on them so I can leave them the way they are.
On the bedroom, it is a different story, it is a 25m2 room, very bright with huge french door, only under coat for now. Not sure how to go forward. Was expecting more tips from this forum. No money for a decorator and I have 2 10L tins of matt in garage.
Thanks.
Letty

As said, unfortunately it's not just a matter of rolling the paint on the wall.
Now you need to sand down the streaks and repaint.
I've decorated many houses, but always admitted that it's not my trade.
My finish is good, but a decorator finish is miles better.
That's why I have my house painted by decorators, despite having been in the building trade decades.
Diyers trying to paint in their spare time must accept that the job will not be perfect.
If they can't live with imperfections they should call the professionals in.
Decorating is not as easy as people think.
Many factors affect the final result, walls, plaster, paint, weather conditions, brushes and rollers, and most importantly the "hand" of the decorator.
Again, hats off to the decorators.

Ive used tikkurelia paint on my kitchen project and by far the best paint Ive used. Ive bought Johnson's trade etc etc never got the same finish. I think they call it framing with white paint. Its stretching, rolling dry paint etc etc. Rolling skills very important and obv the roller. Again Ive bought some rubbish from B&Q over the years now I just stick to Hamilton/Pro-dec etc as affordable rollers.
