Issues with painting

[user1489844432]

Hello

I had my first go at painting yesterday. Unfortunately results are far from what I expected.

Any ideas whats causing this issue please?

What are you painting over, what are you painting with? Is that just one coat?

[user1489844432]

I am painting with Dulux Pure Brilliant White emulsion paint. I painted over dark green pain that was on the wall previously. This is first coat.

If you're painting over dark green paint with a light colour you will need at least 2 coats, possibly three.

[icedbun5]

That's totally normal for a first coat, especially when you are painting over a darker colour. You are doing just fine.

[user1489844432]

I get that but my issue is not with dark color showing through but with wired texture / look of paint in some places

[HasaDigaEebowai]

Thats probably just because in some areas you've gone over it more than once with the roller. Its difficult to see it as texture from the photos but it could also be that you've not rolled it out enough and so there's too much paint sitting in some areas. Or that you've used the wrong roller (one designed to create texture).

Did you wipe the walls down at all with sugar soap or similar? It could be grease coming through.

[Kezziethecat]

It just looks like you need a couple more coats. Did you put a primer or base coat down first? I always paint a base coat of cheap white emulsion before putting the colour I want on. Then you will need 2 or 3 coats.

What room is this. It does look like damp or grease marks.

[user1489844432]

It is dining room, photos are of internal wall, top part so very unlikely it would be damp. Difficult to describe thr texture, it feels rough/coarse but other part of the wall are fine. So I am at a loss here what are the next steps and how to avoid in the future.

It could be that parts if the wall have had something screwed to them or someone’s punched a hole in them and the previous owner has tried to fill the holes it cover over them with polyfilla or something so it’s not quite the same texture.

If it’s rough in places you can use sandpaper (wrapped round a block of wood or a block you can buy) to achieve a smooth finish.

Then paint over. If you are using a roller the fluffy head should leave a consistent slight ripple all over the walls and hide it a bit.

I agree with HasaDigaEebowai that you may have over-rollered it. The Dulux water based emulsion starts to dry very quickly and you end up pulling more paint off if you try to go back over it with the roller. Colouring dark paint with light usually means at least 2 coats.
I also found that in the warmer weather a little water mixed with the Dulux helped, and not using a roller with a too deep a pile.

[user1489844432]

Whats best way of fixing it? Do I need to sand it down or just put another coat over?

[Mutunus]

Did you rub down the wall to start with?

Depends how "deep" the imperfections are. Unless you want to rub down the whole wall again, I would just try smoothing the worst areas so there's not a big step between the good and bad area and put some paint on.

[RollercoasterRaver]

Preparation is the key...it's a pain in the arse but so worth it. Rub it all down again and then another coat.

[Zandana123]

I've got a 1/3 sheet finishing sander and whizzed it lightly over walls between coats.

Found out I got poor texture if I loaded too much paint on the roller and didn't spread it enough.

Equally if I was too slow and rolled back over a section it would ruin the texture.

Paint settles and smooths/levels as if drys, so if you overroll it whilst it's going tacky it can't do that.

[BluePaintSample]

First thing you do before painting a wall is sand it smooth, feel the surface of the wall with your hands to ensure you have everything smooth, then wash the walls with sugar soap. Only then do you start painting.

The dark green may have hid a multitude of sins that the white paint is now revealing. So did you do any prep work?

[BluePaintSample]

You will have to lightly sand to remove the texture otherwise it will just show through again.

It could be you have overloaded the roller with paint, don't ever be tempted to go back to an area, always leave it to dry and assess then.

[InthekeyofG]

Are you painting with matt paint over silk paint? That can cause problems I believe. But is possible with preparation

[Bluntness100]

That looks like the old paint bubbling through.
