PRO LIQUID FINISH™ RS (sand-free) is a sand-free, abrasion/scratch resistant, super-high fluidity, fast-curing, polymer-modified, calcium aluminate cement-based hybrid product that can be used as a self-leveling underlayment or patching compound (depending upon the amount of water added). This super-high fluidity self-leveling underlayment can either be pumped or trowel applied from 1.5 mm (1/16″) up to 12 mm (1/2″) in thickness. When the product is used as a self-healing patching compound, it has a longer typical pot life and can be applied from 1.5 mm (1/16″) up to 12 mm (1/2″) in thickness. PRO LIQUID FINISH RS (sand-free) is made with HYDRO GEL in its formulation to create an ultra-smooth and ultra-fine finish that requires no sanding. The amazing Hydro Gel technology allows the product to be used very thin as a self-leveling underlayment OR used as a self-healing, high-performance patch, depending upon the application. The first and only product of its kind!
