Innovative/Insulmastic 3405 R-20 Horizontal Retarder - 4 L Bottle

A waterbase solution which is applied directly to a fresh concrete flatwork surface to retard the set of the surface cement to obtain an exposed aggregate surface.

Features

• When sprayed on fresh soft concrete will retard the cement and expose the aggregate to produce a three dimensional surface
• Will retard the set of the surface cement between 12 to 24 hours after application and when applied as directed. The amount of retardation will be influenced by the concrete setting time which, in turn, is influenced by air temperature, mix design, slump, wind, concrete temperature and humidity
• Will only retard the surface cement and will not retard or "kill" the set of the mix
• The product is a blue liquid
