Patchy wall paint advice

[JamieB3009]

Hello,

I am after some advice regarding a patchy wall issue as im at my wits end with it now!!

I have been painting all walls in my kitchen using dulux trade diamond matt and a hamilton perfection roller. All walls look great but I have one long wall which is approx 7m long and when the light through a set of patio doors hits across it at a shallow angle it looks so patchy. I have put 3 coats on, tried doing the wall in small sections to keep a wet edge and made sure not to over work the paint but it still looks patchy. Can anyone recommend what would be best to sort this? Would sanding it down and repainting with the same paint be best or would it be better to go for something like ultramatt (which i have used on the ceilings) to have less sheen? Are priducts such as dulux basecoat any good for trying to even things out before.a recoat?

Any advice is greatly received.

Thanks

Jamie

15 inch or bigger roller.
Paint horizontal.
Load roller and roll right to left in one go along ceiling line. I hold roller in my hand,
keeping an even speed.
Load roller. Drop down 12 to 13 inchs for overlap and roll right to left in one go.
Don't be tempted to do any above where you painted. What is stays.
Finish along skirting.


Even when I paint wall horizontal I do a band top to bottom and remove roller from wall then top to bottom so it is keeping roller nap the same.

I often finish a big wall horizontal though

Thank you for the response. I didnt think to go horizontal as most things recommended vertical but I will most definitely try that. I am by no means a professional but aim to get a good finish. Below is a photo of the wall in question.

Being a durable it don't like dry walls. Seal with Gardz and diamond matt flows on a treat

Thank you!! Ill try the gardz! One question does that need to be sanded before applying gardz?

The diamond matt has sealed the surface now so unless its rough I would not sand or seal.
Don't think you will get the benefit of gardz now but maybe on the next one

Hi Wayne's,

Tried a horizontal coat and no real improvement. Wnat would your recommendation be? Would i be better giving the entire wall a light sand and then go to something like ultramatt, on the basis it should be the same white as the other walls, but has less sheen to show patching?

Thanks

You could try something more matt.
It won't be so durable though.
The white might be different to the rest as white is a colour. Different bases look a different colour even when they have the same name. Even white...
Ive had this problem with critical light on some walls and it's not easy or even possibly to fix.
Your best option is to sand then spray the wall and hope that improves finish.
if its a critical light shadow from an uneven wall then not much you can do.

The worst wall I had was a hall passage.
Light came through front door and it locked terrible. I could see every concrete block.
I skimned it and painted twice and second time with a solid 600mm blade.
When you put a metal ruler on the wall there was virtually no gap. What gap of light was getting under ruller was so narrow I couldn't slide paper under it, but it still looked terrible.
It originally had paper on the 1960 house and I said that putting embossed paper was the only way they would fix it.
They weren't happy and I lost over £1000 on that one but I couldn't do any more.
Very unique problem that one.
The tolerances for this problem are so small that you just can't get rid of it by hand.
