I come across concrete sealers are super uncomplicated to use. Just cleanse the concrete, let it dry, then apply the sealer having a mop. It gained’t alter the coloration of the concrete, but will darken it a little and incorporate some gloss. You’ll have to reapply it yearly or so https://mcgepoxycoatings.com/epoxy-vs-untreated-concrete-garage-flooring-which-one-is-best/
