Dura Shield L is a high performance, water based concrete surface hardener based on nano-sized lithium silicates. These silicates penetrate deep into the concrete matrix to harden the concrete surface making the surface more abrasive resistant and reduces its absorption of liquids, making the concrete surface dust free and easier to clean.
Dura Shield L is specifically designed to penetrate very tight surfaces such as trowel finished concrete and is ideal for use on polished concrete floors.
