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.
