Need advise on a floor repaint

[jimmys5600]

Hi All, About five years ago I painted my garage floor with
Rust Bullet. It did hold up well but the color never pleased me.
It is a real dark silver,seemed tyo get darker with age. Even a
good scrubbing it looked dirty to me
Im not sanding the floor to get ready for a repaint. What would
work to cover the Rust Bullet coating?

I'm no expert on garage floor paint; but I DID sell paint for 6 years during high school and college and the one constant that has never changed is a paint job is only as good as the prep.

ANY paint will cover the Rust Bullet......but will it STAY there? Not without proper prep!

You can rent a low RPM swing buffer with a few 80 or 100 grit sanding screens from your local hardware store more than likely. Use an orbital for the perimeter around baseboard and around drains, piping, etc - and a medium grit sanding sponge for the 90 degree inside corners. It is a cheap investment especially since your floor is already in good shape.

If you do not thoroughly degloss the surface before recoating it, with any coating, you might as well not even touch the floor.

Agree with Benwah above, but would like to add that not only can a sanding screed be used, but also a 3M type scratch pad works very well to micro-scratch floors for adhesion.

Always wipe down the floor with rags and denatured alcohol before coating.

And yes, the secret is in the prep, and just a caution that any coating can only stick to the surface below it, so if a prior coating starts pulling up your new floor will come up with it, so for that reason we always recommend whenever possible to remove all prior coatings first.
