The details are very important when applying stain or adding epoxy to a concrete floor, which means the outcome could be messy if not done properly. A 1,000+ -pound grinder will need to be used for the project. Plugging this into an outlet in your home could cause serious electrical issues. Each different stain is applied to the concrete in a different manner. Most standard epoxy DIY kits come with an acid etching material and the coating comes up in 1-3 years because the concrete is not prepared properly.
