I uncover concrete sealers are super quick to use. Just clear the concrete, Allow it dry, then implement the sealer that has a mop. It gained’t alter the coloration on the concrete, but will darken it a bit and add some gloss. You’ll really need to reapply it every year https://mcgepoxycoatings.com/epoxy-vs-untreated-concrete-garage-flooring-which-one-is-best/
