What is the best way to seal a concrete floor? Concrete floors are found in garages, basements, warehouses, shop floors and interior floors. In order to determine the best way to seal a concrete floor you need to determine what type of protection and finish you are looking for. If you are looking to polish the concrete it would be best to use a concrete densifier and then polish the concrete floor. If you are looking for chemical and abrasion resistance it would be best to use an epoxy floor coating system. If you are looking for a decorative gloss finish it would be best to use an acrylic wet look concrete sealer. If you are looking to keep the concrete clear with out any sheen you can use a penetrating concrete sealer.
Once you have determined what type of protection you are looking for and what you are trying to seal you can then go about prepping the concrete floor. If the concrete has been previously sealed you will need to remove the previous concrete sealer or wait for the sealer to wear away. If the concrete is new you will need to wait for it to cure 28 days before applying a concrete sealer. If you are going to be applying a concrete coating to the concrete floor you will first need to grind it or acid etch it to achieve a good surface profile. Most sealers are applied with nap paint rollers, garden variety pump up sprayers, or brushes.
Ultimately the best way to seal a concrete floor depends on the type of protection you are looking for and the type of finish you are looking for. Read our other reviews for product recommendations and product selection tips.
