Terraco Terraroc FMR

Terraco Terraroc FMR

Product Overview - Terraroc FMR is a high strength structural repair mortar for vertical and overhead repairs. - It is suitable for hand or spray application. - Terraroc FMR is shrinkage compensated and is suitable for repairs up to 75mm on vertical surfaces and 50mm on overhead situations. Properties - Ready to use - Shrinkage compensated - Factory controlled mix design - High strength fibre reinforcement - Low permeability with excellent durability Areas Of Use - Terraroc FMR is designed for use as part of the Terraco concrete repair system and is recommended for high-build repair work up to 75mm vertically and 50mm overhead, in a single application. Application Method 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 FMR. Mixing - Ensure that the mixing water is constant for each bag of compound (5ltr water / 25kg Terraroc FMR). - 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 FMR to set, scratch the surface to provide a mechanical key and prime with Terrabond A before applying the final layer of Terraroc FMR. - Finish using a steel float. Terraroc FMR should not be applied in layers less than 10mm. Curing - Terraroc FMR 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. - Clean tools and equipment with water after use.
