Micro-surfacing is similar to slurry seal but is generally considered to be stronger and more durable. It is a combination of polymer-modified emulsion, high quality aggregate, mineral filler, water and other additives. By using a quick-setting emulsion, micro-surfacing can be opened to traffic in about an hour in most cases.
