Although installing a new garage floor coating by yourself is possible and can save you a bit of money, there are many benefits to hiring a garage professional. Installing a new garage floor coating requires you to pour either epoxy or polyaspartic solution over the garage floor and allow it to spread over all the imperfections. If you fail to cover the solution evenly or miss significant flaws in the floor, you could end up spending twice as much to hire a garage expert to remove the layer and install a new garage floor coating. A garage contractor has the experience and professional knowledge of evenly spread the solution to cover every small crack or crevice without creating any bumps or imperfections in the new coating.
