I come across concrete sealers are super simple to use. Just clear the concrete, Permit it dry, then implement the sealer that has a mop. It won’t alter the shade on the concrete, but will darken it somewhat and add some gloss. You’ll should reapply it on a yearly basis https://mcgepoxycoatings.com/epoxy-vs-untreated-concrete-garage-flooring-which-one-is-best/
