I come across concrete sealers are super quick to apply. Just clear the concrete, let it dry, then implement the sealer by using a mop. It gained’t change the colour of the concrete, but will darken it a bit and incorporate some gloss. You’ll really need to reapply it each https://mcgepoxycoatings.com/epoxy-vs-untreated-concrete-garage-flooring-which-one-is-best/
