What is an epoxy concrete sealer and what is the best epoxy concrete sealer? Epoxy concrete sealers are topical film forming concrete coatings that produce a hard long lasting abrasion resistance surface. They are an ideal product for resurfacing a concrete floor to product the floor surface. Epoxies exhibit similar qualities to acrylics in regards to characteristics but they are different in performance, lifespan and of course price. Epoxies are an invisible protective barrier that adheres well to concrete factory floors, garage floors and restaurants. A harder material than acrylics they also come in solvent and water based versions. Some water based epoxies are non-porous allowing moisture to escape. But most epoxies do not tolerate moisture well and they are not very breathable. This means that bubbles may occur if water vapor transmission is trapped under the surface after applying an epoxy. Please note that Epoxies should not be applied over a slab with a moisture problem. Epoxies are sometimes used as primers and provide outstanding resistance to chemicals. Since epoxies tend to yellow when exposed to UV rays, they are typically used only indoors. Epoxies are excellent for repelling water and they tend to be used on concrete countertops. Be aware that most epoxies are two component products that are mixed together and then rolled onto concrete. Some negatives include the fact that they require more floor preparation, take a long time to cure and the installation process can be confusing and time consuming. But they last a longer time before needing to be reapplied than say an acrylic.
