What is going on with your garage walls, are they wood, vinyl, brick, have holes, dents...need more info. Could you post a picture? We'd love to help but need details.
Drywall which I have painted. I feel like doing something different.
A friend of ours always keep her’s painting to give it more appeal. Hope this helps!
I did paint it six years ago. I’min a mood to change it.
It would depend on what material you garage is built with. Pressure wash and paint are always the first steps in my plans.
