Using Flat Paint on Flat Paint that had been touched up with Gloss!
I've just repainted a room in our newly-purchased house. The walls had white flat paint; I repainted with a flat color.
Unknown to me, some sections of the wall had been "touched up" by the previous owner with some sort of gloss. (I'm guessing semi-gloss.)
The walls, on the whole, look good. But there are a number of noticeable blotches.
Anyone have advice on how to remedy this is the most effective and easiest way?
I ran a second coat over a few blotches on one 'test wall', and it looks a bit better on the whole. I just worry about flaking, if the flat doesn't fully adhere.
Do I need to sand down to the gloss to scuff that up and then repaint? I'd really rather not, if there's a way to work around this.
Thanks for any help!
