TOP-STOP HORIZONTAL (Canada) - Spray-Applied, Water-Soluble Surface Retarder
TOP-STOP HORIZONTAL is a spray-applied, water-soluble surface retarder designed to slow the set of surface mortar of concrete to produce an exposed aggregate finish. It temporarily delays the set of Portland cement at the top surface, while the underlying concrete sets normally. TOP-STOP HORIZONTAL is easy to use, producing beautiful exposed aggregate concrete flatwork with consistent results. It is non-flammable and VOC compliant.
TOP-STOP HORIZONTAL may be used to produce an architectural finish on concrete slabs by exposing the natural colour and texture of the aggregate. TOP-STOP HORIZONTAL exposes the aggregate on floor slabs, sidewalks and tilt-up and pre-cast panels or any normal horizontal concrete application. It produces roughened bonding surfaces for subsequent concrete toppings and roughens horizontal surfaces for construction joints in power plants, dams and other civil engineering projects The rough finish obtained from using TOP-STOP HORIZONTAL may be used as a mechanical key for later concrete lifting or rendering.
