RONABOND HB40 ULTRA RAPID
Rapid setting high build concrete repair mortar
RonaBond HB40 Ultra Rapid mortar is used for repairing concrete on vertical and overhead surfaces where ease of application is as important as strength.
RonaBond HB40 Ultra Rapid can be applied in relatively thick section to walls and soffits and, depending on the nature of the repair, in layers up to 75mm depending on size and orientation. RonaBond HB40 Ultra Rapid is suitable for use at lower temperatures, minimum 20C. Multiple layers may be applied in a single day depending on temperature.

ADDITIONAL LAYERS
When multiple layer application is required, each intermediate layer must be combed and allowed to harden before application of Ronacrete Rapid Primer and a further layer of mortar. The repair must be finished with a steel or wood float, and may be dry sponge finished if required. If applying a protective or decorative coating such a RonaBond Crack Bridging Anti Carbonation Coating WB or RonaBond Anti-Carbonation Coating WB, leaving the final layer with a sponge finish will aid adhesion.
SHELF LIFE AND STORAGE
RonaBond HB40 Ultra Rapid should be stored unopened between 10°C and 25°C in dry warehouse conditions and out of direct sunlight. In these conditions shelf life is approximately 6 months.
