Concrete countertops are difficult to seal for a number of reasons: most are very high density and therefore not very porous. As a consequence our penetrating sealers will not work well unless the countertop is etched.Our topical sealers like AFM Mexeseal MAY work, but not over the top of other sealers. We offer 4oz samples, you can try over an inconspicuous area and see if it gives the desired effect. Disclaimer : this is an outside the box use for Mexeseal, not guaranteed by us or the manufacturer, uncharted territory, proceed at your own risk.
