Selection guidance

RM770 is primarily for large-area spray-applied concrete repair, not a general lightweight mortar for small patches. Confirm spray equipment, repair build, reinforcement treatment and layering from the latest TDS and repair design.

Browse the Optimix product range or other concrete repair mortars. Refer to the latest official TDS attached to this page for technical values, application method and limitations.
