Painting Plaster Patch - differant shade rest of room

DIYnovise

Dear All, hope you can help

Just moved into a new house. Knocked out a large brick fireplace and mantel. I plaster boarded the hole and got a professional plasterer to skim. I painted with half and half x 3 coats once plaster was dry and have painted with 2 coats of Dulux endurance.


Here's the problem - the grey paint is a different shade (lighter) on the new plaster than the rest of the wall


Any ideas would be welcomed

There are a whole ramge of reasons why its a different colour. Thats why patch painting is never encouraged. You need to paint the whole chimney breast so that the whole wall is the same colour.

If you are not a plasterer, I would suggest you don't re-skim the whole wall yourself.

When walls are plastered, even if done at the same time, they do end up with different shades on different parts of the wall.

We had a previous house skimmed top to bottom. We did the multiple mist coats. And then after that it took 2 more full matt coats on top. Plus, I gave the worst areas another going over as well.

As long as the wall is nice and smooth, it is just a case of using the mist coats first (which you have done) and then just painting it and re-painting it until you have it all consistent and can no longer see the plaster. But it will never match the rest of the room if you don't do it at the same time.

Rather than get the whole wall replastered could you get some lining wallpaper and do it with that, then paint.
