When going to paint old or blistered paint on a 3 bay garage, what is the best process? I wonder if i scrub it first,even it is blistered
with years of not repainted. and what is the process for chalk ...painting?

Do you know what chalk does? that is.
I know it's not perfect writing, but I think you know what I would like for the
answers. Thank you so much...............

    Are you referring to a floor?

    Hi! I'm not exactly sure what surface you're referring to but chalkpaint in my opinion is always the easiest way to go, it requires the fewest steps and adheres to most surfaces. But, it does sound like you're going to need to clean the area well first, and depending on how dirty or uneven the area is, sand it down somewhat to give you an even starting point.


    Good luck!!

    I can not tell if its the floor or the garage doors that need work.

    What ever it is, sand it to get rid of the blisters and loose paint, clean it, prime, ...if its the floor there is special paint for garage floors that have epoxy in it...it creates a hard surface that your car can drive on and can be cleaned easier.


    If its the doors, sand, wash, prime and use a good exterior paint and exterior sealer.
