Roller marks everywhere

daggermark · 21 Apr 2020

A pro job wouldn't normally have lap marks - I am quite anal about laying off and ensuring I don't get any.

I would say the majority of houses have them tho - probably nobody other than yourself or a decorator would even notice them!

I’m one of them that if I know it’s there.... it has to go
I’m certain I won’t get lap marks if it doesn’t dry as quick, so will add some water.
Thanks

I know the feeling - finished my lounge, turned the wall lights on... cast a shadow on some filler I'd missed when sanding the wall. Nobody else has even noticed it but I can't stop staring at it!

Let us know how you get on.

So I watered it down a fair bit and never made much difference. After speaking to a painter friend, he mentioned it’s probably the heat and sunlight as it’s an extension with a large bifold opening with no doors yet. So..... I painted again tonight after it had cooled. It was a lot easier to lay off....
However, I’ve juts been out and put an LED light over it and can literally see every roller mark? It went on nice and even. I don’t get it. I shone the light on other parts of the house that look completely fine, but they under the LED exactly the same.
Maybe I just need a more expensive paint

I like Wooster but I would try a different sleeve. I roll ceiling and walls with Purdy Colossus sleeves.

I think your roller might be soaking up too much paint and that given that ceilings are more awkward to paint, you are applying too much pressure. if that is the case using a shorter nap roller will result in even more paint splurging out of the edges.

Personally I am not a fan of the low latex emulsions (Leyland Trade Super Latex, Dulux SuperMatt, etc). They are designed to allow moisture in new plaster to evaporate out of the wall through the paint. That is to say, they are designed for walls that aren't quite ready to be painted with regular emulsion. The low levels of latex/acrylic makes it virtually impossible to keep them clean. You can't wipe away fingerprints or smudges. Another issue with them is that they do little for the level of suction in the plaster. I have had the misfortune of assuming that the existing emulsion on a wall was standard matt, only to discover that it was a low latex paint and I should have diluted the first coat of my matt emulsion.

One advantage of the low latex paints is that when painting ceilings the low sheen level makes it easier to maintain a constant sheen. There are however better paints, eg Dulux Ultramatt it is so matt that you can touch in the paint without affecting the sheen levels.

Well it’s very frustrating, I could just leave it but it’s the room I will spend most time in. It does seem that I ain’t getting much out of that roller sleeve. I’m going to get some ultra Matt then and give it a final coat with it. Then give up

This is how my wall turnt out, and it’s the same on ceiling. Wasnt applying too much pressure and felt I was applying even.

Thanks for posting the image.

Are the walls skimmed plasterboard or tape and join? I am confused by how perfectly parallel the vertical lines seem to be.

Are they after applying Dulux Trade Ultra Matt?

I've always thought that the lines were due to overdipping the roller so it carried paint on the ends, and not rolling them away when they occur.

Isn"t that right?

The walls are boarded but plastered.
I havnt been able to get any Dulux Matt ultra yet. Out of stock. The pic is from the last coat of Leyland trade.
The lines are perfectly straight because I’m rolling perfectly straight. Starting 5 inches away from last roll and then rolling back in overlapping last one. Then working out until it’s gets thin on the sleeve.
Maybe I’m just terrible
It has to be the roller not holding enough paint and a crap paint.

Thanks for the clarification. It looks like a suction issue- possibly related to the first mist coat. Did you dilute the first coat by 10%.

I couldn’t tell you the exact percentage but it would have been more than 10%. Usually would try do nearer half and half

So you don't work the roller crossways and to and fro, to spread it out and even it?

I don’t go side to side all the way up and down.... I use the paint from the initial spread and go either side of it then go back over it all.

I do the same but I thin the paint as per the instructions on the tin. I think you may have over thinned the mist coat.
