I uncover concrete sealers are super straightforward to use. Just cleanse the concrete, Permit it dry, then use the sealer by using a mop. It won’t alter the colour from the concrete, but will darken it a bit and include some gloss. You’ll should reapply it every year or so https://mcgepoxycoatings.com/epoxy-vs-untreated-concrete-garage-flooring-which-one-is-best/
