OPTIMIX RM770 Repair Mortar (Sprayable) is specially formulated for reinstatement of large areas of spalled concrete caused by reinforcement corrosion, fire damage or other areas where spray application provides a cost effective reinstatement method. OPTIMIX RM770 is particularly suitable for use as overlayment for titanium anode mesh of the cathodic protection system. It can be used for both vertical and overhead applications without the use of formwork. In general, OPTIMIX RM770 can be applied up to 100mm for overhead application per layer. Depending on the density of the exposed reinforcement, reinstatement using multiple layer application is also appropriate.
