Preparation of Surface
Do not apply at temperatures below 5oC. Remove all defective concrete back to the reinforcements, treat reinforcements with Epiprime ZR (see separate data sheet). Avoid feather edging. The repair area should be a minimum depth of 10mm. Thoroughly wet the surface with water and apply a coat of Terrabond A by scrubbing it well into the surface.
Allow it to become tacky before applying the Terraroc MBR..
Mixing
Ensure that the mixing water is constant for each bag of compound (4.5 ltr water/25kg Terraroc MBR). A mechanical mixer is necessary to ensure consistency of the final mix. Add the powder to the water and mix continuously for 3 to 5 minutes.
Application and Cleaning of Tools
Apply to the prepared substrate by trowel ensuring that it is well compacted onto the primed surface/reinforcements. Build up in layers until the desired thickness is achieved. Where very thick sections are required allow the initial layer of Terraroc MBR to set, scratch the surface to provide a mechanical key and prime with Terrabond A before applying the final layer of Terraroc MBR. Finish using a steel float. Terraroc MBR should not be applied in layers less than 10mm thickness.
Clean tools and equipment with water after use.
Curing
Terraroc MBR should be cured immediately after troweling is finished by applying Terrabond A to the surface. In harsh conditions the supplementary use of hessian or polythene must be used to ensure proper curing.
