Chemcrete LSR is a liquid surface retarder for use on horizontal concrete surfaces. It is used to delay the setting of the surface layer of freshly placed concrete.
When the main concrete mass has set, the surface layer can be brushed or washed off leaving an exposed aggregate surface. This exposed aggregate finish can be used to provide a mechanical key or as a decorative finish.
• Low viscosity liquid
• Apply by spray
• Medium penetration
• Can be used for exposed aggregate finishes
