Has anyone used this on a cement patio? How well does it fill cracks in the cement? Will it cover rust stains?

Lola, our Restore 10x Advanced is an excellent coating option for a concrete patio. This coating can fill and completely conceal cracks up to 1/4" wide. The coating will cover a rust stain on the concrete, as long as there is no rusty metal in the concrete which might continue to create rust, as this could potentially bleed through the coating over time.
