Epoxies: Provides excellent resistance to chemicals and can be used in conjunction with paint chips or metallic sand to provide a decorative and durable finish. For added protection use a urethane topcoat for a higher build floor. Make sure to have a rough surface porosity before applying an epoxy to help with hot tire pickup resistance.
Urethanes: Provides excellent chemical resistance for protection from oils and fluids. Look for an aliphatic urethane that will withstand more chemicals and last for a longer period of time. Make sure to have a rough surface porosity before applying a urethane to help with hot tire pickup resistance.
Polyaspartics: Fast drying urethanes that are all the rage because they will be dry within a few hours compared to the dry time of a traditional urethane which can take up to a week to cure. The only down side is the extremely short pot life that needs to be applied in less than a half hour. This can be problematic on large square footage garages. Make sure to have a rough surface porosity before applying a polyaspartic to help with hot tire pickup resistance.
Penetrating Sealers: The best options for garage floors if you are looking for a natural finish that will not cost a lot of money but will give an extreme amount of protection. Penetrating, water repellent sealers can create an olephobic barrier resistant to oils, fluids and water. We like the Siloxa-Tek 8505 available at HomeDepot.com. You will never have to worry about this industrial grade sealer peeling, flaking, bubbling or delaminating.
