بودرة الأسمنت فوسروك ريندروك (LA)

Fosroc Renderoc products are used for repairing voids, blowholes, and damaged concrete on vertical and overhead surfaces. They can be applied from a feather edge up to 3mm thickness. Renderoc mortars are also used for reinstating horizontal concrete surfaces.

Fosroc Renderoc products are easy to use, provide high bond strength, and are cost-effective. They conform to the requirements of BS EN 1504-3 for concrete repair materials.

The surface should be clean, and free from dust, unsound material, plaster, oil, paint, grease, corrosion deposits, or algae. Roughen the surface to remove laitance and expose the fine aggregate by light scabbling or grit-blasting. No independent priming system is required.

For low temperature working below 5°C, use warm mixing water up to 30°C and adopt normal precautions for winter working. For high temperatures working above 35°C, store the material in the shade and use iced water for mixing.

Correct curing is essential for optimum performance. Leave the formwork in place until the compressive strength reaches 10MPa. After striking the formwork, thoroughly soak the repair with clean water and spray with a liquid curing membrane like Concure A99.

Fosroc recommends using the Dekguard range of protective, anti-carbonation coatings over the repair area to provide a decorative and uniform appearance and protect the structure from the environment.
