INSTRUCTIONS FOR USE
MIXING
Mix RonaBond Concrete Repair Mortar in a forced action mixer (eg. Creteangle or Baron pan mixer) or mix single pack mixes with a slow speed 1kw drill fitted with an MR4 type paddle. Do not use a free fall mixer. Add all of the supplied gauging liquid to the mixer or mixing vessel, commence mixing and gradually add the powder component for approximately 3 minutes, until components are fully dispersed.
PRIMING
Mix and brush apply Ronacrete Standard Primer to the steel and allow to become tacky, not dry. When priming coat on steel is tacky, brush a single coat of Ronacete Standard Primer on to the damp concrete and apply a second coat on to the steel. Ensure that the first priming coat applied to the steel is not removed during the application of the second coat. The concrete repair mortar must be applied on to the wet or tacky primer before the primer dries. If the primer dries it must be thoroughly scarified and reapplied.
PLACING
Apply in layers to achieve the required thickness, reform the original profile of the concrete and cover reinforcing steel. Layer thickness will vary according to the shape and size of the repair, the nature of the substrate and mixing and application technique. Minimum depth of application is 6mm. Maximum depth per layer 35mm. Apply not less than 15mm around reinforcing steel. Compact to prevent honeycombing and voids. Scratch the face of intermediate layers, allow to firm up and apply Ronacrete Standard Primer immediately prior to applying the next layer.
PREPARATION
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.
All surfaces must be cleaned to remove all loose dust, debris and surface contamination which may prevent adhesion of repair mortar to concrete and steel. Water used must be clean and of potable quality. When repairing chloride contaminated concrete any exposed reinforcing steel must be grit blasted or similarly prepared back to bright, uncorroded steel. Following preparation of concrete and steel, thoroughly damp all concrete surfaces to be repaired. Remove any standing water
