    Painting over this knobbly wallpaper and the cutting in at top has dried a different colour to the rest of the wall. What to do? 20190405_140001.jpg 20190405_174142.jpg 20190405_174221.jpg 20190405_174131.jpg

    There appear to be wet patches in your photos (the darker patches seem to be the wetter areas). You got to give everything longer to dry before you can tell if you have a problem. If it is dry, then it needs another coat. Anyway, as far as the cutting in area coming up different to the rest, you must cut in a stretch and paint up and down before the cutting in paint dries (maintain a wet edge) and/or use a mini roller over the cutting in area (I don't think this will make much difference in what you got).

    It's been two days and has dried a different colour. The paint is too similar to the wallpaper colour but that's a separate issue. I cant see what you're painting. I'm wondering if the knobbyly bits
    In wallpaper have caused this, when I drag brush to the side when cutting in. Maybe I need to cut in by pulling brush downwards. Not sure.

    After cutting in you may have to use the brush vertically to fill in between the knobbly bits. Use a longer pile roller sleeve than whatever you are using to paint ... you are not getting enough paint on the wall or in between the knobbly bits.

    What paint are you using - I've had this from Dulux Diamond Matt before - I think it's to do with the paint drying at different rates between brushing on and rollering. It could also be because your cut in edges are fully drying before you roller?

    I got round it (in a downstairs cloakroom) by raising humidity to slow down the drying of the paint (it was in the really hot weather last year.)

    More recently a decorator I talked to about it suggested cutting in then immediately going over the bit you've cut in with a mini roller e.g. cut in, mini roller, move on to next bit to cut in etc. obviously you cant get right to the edge with the mini roller but it helps prevent that 2" band you're getting.

    That's the advice I got from fecorators. Mask around coving then mini roller it. Not seeing what you've painted is also a problem. The paint colour and wallpaper colour are too similar

    Not quite what I was told to do - cut in with a brush then go over it immediately with a mini roller, you won't get right into the edge but it helps blend the paint in for when you come back with the large roller.

    Other thing I'd suggest is close the window/doors.

    I try to avoid using any masking tape on top of emulsion.

    Definitely caused by cutting in the whole wall which is slower due to the knobbly pattern, I would have a 4" inch mini microfiber roller and soon as I cut in a area I would roll over it.
