Please tell me, I painted the inside corner of the room, and now it shines from the paint, and the adjacent walls look normal.
Painted as follows: the brush went through the corner, distributing paint brush from the corner to the right and left on the walls, then on each wall paint rollers 250 mm, trying not to touch the roller adjacent wall.
How to paint the corner is not shiny, and its appearance would not differ from that of the walls? I have other rooms in the queue, I do not want to repeat the mistakes.
I think the application technique has nothing to do with whether there will be glare or not.
I painted the corners with a brush up and down without spreading anything... then with a roller as usual... nothing glitters. The easiest and cheapest paint is white matte.
You probably don't have matte paint, that's why the glare is there. Or it's more likely that the glare is due to the wallpaper glue you didn't clean up.
