I uncover concrete sealers are Tremendous quick to use. Just clean the concrete, let it dry, then use the sealer that has a mop. It gained’t alter the shade in the concrete, but will darken it a tiny bit and add some gloss. You’ll really need to reapply it yearly https://mcgepoxycoatings.com/epoxy-vs-untreated-concrete-garage-flooring-which-one-is-best/
