What is the procedure for applying additional coat(s) of Rust Bullet for Concrete after my project has been completed and is dry/cured?

If additional coat(s) of Rust Bullet is needed and more than 24 hours have passed, the coated surface should be scuffed up with at least a 150 grit to reopen Rust Bullet’s pores. Only a light scuff is required to break the glaze of a cured Rust Bullet Coating to allow for adhesion of another coat. This 24 hour period is decreased in areas with higher humidity levels.
