FINISH
Smooth surface finish prior to application of protective/decorative coating
PERFORMANCE
Pre-packed formulations offer assurance of consistent high performance

ADDITIONAL LAYERS
When multiple layer application is required, each intermediate layer must be combed and allowed to harden before application of Ronacrete Standard 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.

INSTRUCTIONS FOR USE
CURING
Cure with Ronacrete Curing Membrane or tight fitting polythene as soon as possible and as quickly as is practical to prevent rapid early moisture loss from the mortar surface and minimise the risk of resultant plastic cracking. Curing is more important when working in direct sunlight and/ or in a drying breeze or wind. Note that maximum application depth per layer is reduced and typical maximum layer thickness in larger repairs is 50mm vertically and 30mm overhead.
SHELF LIFE AND STORAGE
RonaBond HB40 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.
SITE ATTENDANCE
When on site Ronacrete representatives are able, if asked, to give a general indication of the correct method of installing a Ronacrete product. It is important to bear in mind that Ronacrete Ltd is a manufacturer and not an application contractor and it is therefore the responsibility of the contractor and his employer to ensure he is aware of and implements the correct practices and procedures to ensure the correct installation of the product and that liability for its correct installation lies with the contractor and not with Ronacrete Ltd.
APPLICATION
The mortar must be applied to the wet or tacky primer before the primer dries. If the primer dries it must be thoroughly scarified and reapplied. Apply the mortar to reform the original profile of the concrete and cover reinforcing steel. Ensure that the mortar is fully compacted, paying particular attention to avoidance of voids around reinforcement. Layer thickness will vary according to the shape and size of the repair, the texture of the substrate and application technique. Application techniques include hand packing the mortar on to the surface.
When multiple layer application is required, each intermediate layer must be combed and allowed to harden before application of Ronacrete Standard 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, RonaBond Anti-Carbonation Coating WB or RonaBond Masonry Paint WB, leaving the final layer with a sponge finish will aid adhesion.
