I was spraypainting a few things black and accidently got it on the side of my house. It isn't that bad but noticable. Does anyone know a trick to removing it?How can you remove spray paint from walls?
I don't think you can remove it. The paint probably adhered to the other paint. You may just have to repaint that part of your house.How can you remove spray paint from walls?
paint thinner or gasoline
If it is just over spray gasoline should work but make sure you rinse it off VERY well..... My father had over spray when painting the fence and got some on the car, the gas removed the paint without damaging the car.... Also what type of siding is on the house (vinyl, wood, stucco???) If it is vinyl just put a bit on a cloth and rub... wood or stucco you may need to paint.
I don't think it comes of. Try painting over it with wall paint a few times.
Alcohol or Paint thinner might do it, also theres this stuff they use in autobody that might work.. its called rubbing compound.
