Micro-topping is a cement–based resurfacing coating that can be applied quickly and easily to indoor and outdoor concrete tiles and flooring, as well as walls. It fixes directly to the underlying concrete, giving you a highly durable result that enhances old and new surfaces. When Do You Need Micro-Topping Products? Essentially, micro-topping is used to enhance concrete floors or walls by giving you a blank canvas for adding decorative textures, patterns and colors to your surfaces. It can be used on plain concrete floors, concrete tiles and even decorative concrete surfaces. This makes it ideal for quick and easy renovations from poolside and patio areas to indoor spaces.
