I've been having a pint of paint tinted to match the color on walls in our house that we are going to sell. I want the paint to cover where there will be holes from hanging stuff on the walls.
I have been back repeatedly to get a bit more tint added until now I have a perfect color match. But the level of sheen in my paint differs from what's on the walls. So if I look at the new paint dried on the wall from one angle, it disappears completely into the wall, but change angle and it looks very obvious.
Paint store says there's no way to match the sheen. There's nothing they can add to my perfectly colored paint to make it shine a tad more.
Anybody got a solution for the sheen difference? What we started with in my sample is an egshell finish paint. Looks like what was painted on the walls may have been a satin finish.
My builder wanted a large up charger for gloss and semi gloss paint for the very reason you discovered. It is next to impossible to make an undetectable touch ups without repainting the whole wall.
Can you arrange furniture or some other "obstacles" to encourage people to view from the angle where the mismatch is less obvious? (This is not meant as a joke, but a suggestion.)
Keep a couple of things in mind. You are selling the house and right now trying to make it "perfect" to avoid buyers objections and to not turn off a potential buyer. You are staring at this problem with intensity. Buyers will be looking at the whole thing and may not even notice this.
And, if they notice they may not care because they are going to repaint anyway.
Let a friend unaware of the paint issue look around and see if they pick it up.
Whenever I have to repaint an area more than a couple square inches, I just go over the whole wall, until I reach an intersection with another wall or ceiling, or both. Usually the adjacent wall or ceiling will have a completely different angle of light hitting it and so will look completely different from the wall you are repairing. The mismatch in sheen won't be noticeable then.
