Garage floors are one of the most important and understated parts of our homes. While we tend to think of the concrete of our foundations and our basements as being important, the garage floor can slip away from our notice. However, garage floors are equally valuable for the visual aesthetic appeal of your home, as well as for the structural integrity of your house. Garages are a sort of gateway into your home, and you do not want anything going wrong with the garage floor, as fixes can be costly and time consuming.
The best way to prevent any problems, of course, is to apply a concrete sealer to your garage floors. As garage floors are a boundary between the outdoors and the indoors, a strong concrete sealer is needed. One route would be the use of a penetrating concrete sealer that is also a salt and stain repellent. Siloxa-Tek 8505 will penetrate past the surface of the concrete to impregnate the concrete. The Siloxa-Tek 8505 is a water based, silane/siloxane blended sealer that is able to resist spalling, cracking and degradation when exposed to deicing salts. Also because of the fluoro polymer in the formula, it also repels staining from oils and greases which is especially helpful in garage applications. If you have an industrial or commercial garage the Siloxa-Tek 8510 is the solvent based version of the Siloxa-Tek 8505 and an excellent choice.
The other main concrete sealer option for a garage floor is an epoxy floor system with a urethane topcoat. Epoxy sealers like Epoxy 325 are surface level sealers that bond to the concrete substrate, exhibiting excellent protection from heat, salt, water, abrasion, scratches, and the various spills from your car or workbench. To enhance the concrete sealers performance even further, it is best to use an epoxy floor system, that features an epoxy basecoat followed by a urethane topcoat. Urethanes like Urethane 645 are clear sealers that are even stronger than epoxies, featuring all of the same benefits with added chemical resistance properties and UV protection. Either an epoxy system or a penetrating densifying waterproofing sealer would be excellent to protect your concrete garage floor from man-made errors and the elements.
