I am having a home built. I would like to paint the garage floor with Behr Granite Grip. Since it is a new home can I just sand and paint it? Thank you.

    You should do some checking with the manufacturers and also read the directions on Granite Grip. – JACK Jul 31 at 14:23

From the provided product manual:

(Proper surface preparation is required.) All surfaces must be clean, sound, dry and free of any dirt, oil, and grease. Uncoated Concrete or Masonry Surfaces: Allow new surfaces to cure 30 days. Clean and etch surface using a product such as a muriatic acid etcher (read and follow all manufacturer’s label directions) to achieve a textured profile similar to 150 grit sandpaper. Previously Coated Surfaces: For a painted surface in sound condition, use a product to clean and prepare the surface. If the coating is failing or peeling, use a paint stripper to remove old coating or scrape/sand down to a sound concrete surface. Scuff sand glossy surfaces. Clean and spot etch any exposed concrete. Remove all dust with a damp cloth, allow to dry.

  • I always acid etch when painting concrete. I usually use epoxy paint specifically made for garage floors , some cheap brands peel up because the heat from tires. – Ed Beal Jul 31 at 18:01
