One of the most common applications of a concrete sealer is a garage. Mostly all residential homes and shop floor garages are constructed out of concrete. Reasons you may want to seriously consider sealing your garage floor is to protect it from oil, fluids or just to give it a decorative finish. Depending on what you are looking to achieve, there are a few options when it comes to sealing a garage.
It is recommended to use either a penetrating sealer or an epoxy system on a garage floor. A penetrating sealer like the Siloxa-Tek 8505 or the Siloxa-Tek 8510 is best if you are looking for natural finish. The major difference between the two products is that the Siloxa-tek 8505 is water based and the Siloxa-Tek 8510 is solvent based. The Siloxa-Tek products will resist degradating deicing salt damages to reduce cracking and spalling and they will resist exposure to grease and oils.
If you are looking for more of a coating or decorative finish a better choice would be an epoxy system. A thin build epoxy system consists of an epoxy primer like Epoxy 325 and a urethane top coat like Urethane 645. However, if you want to get really into it and make concrete sealing fun, you can add decorative paint chips or metallic sand for a high build decorative garage floor. Penetrating sealers and epoxy systems are popular concrete sealers for a garage.
