طينة الأسمنت فوسروك ريندروك (HS) وزن (25Kg)

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.

Fosroc Renderoc HS is a shrinkage-compensated, polymer-modified, fibre-reinforced repair mortar system designed for structural concrete and masonry repairs. It is supplied as a ready-to-use blend of dry powders that only requires the addition of clean water for application.

Renderoc HS is suitable for various applications, including repairs to structural members subjected to repetitive loading, and repairs in industrial areas, and marine environments. It can be applied by trowel or wet spray, making it versatile for different repair needs.

The product offers rapid application through wet or dry spray techniques, low rebound during application, and extremely low permeability, which enhances resistance to aggressive environmental elements. These features contribute to both efficiency and durability in repairs.

Renderoc HS exhibits impressive compressive strength, achieving over 30 N/mm² at 1 day, exceeding 50 N/mm² at 3 days, and reaching up to 70 N/mm² at 28 days when mixed with a water-to-powder ratio of 0.15.

To mix Renderoc HS, add 3.75 litres of clean water per 25 kg bag and mix for 3-5 minutes until homogeneous. The application can be done by hand or spray methods, ensuring a minimum thickness of 10 mm is maintained over the entire area.

Renderoc HS should not be applied when ambient temperatures are below 5ºC or if the surface is exposed to running water before the final set. Proper substrate preparation is crucial to ensure adhesion and performance.

The shelf life of Renderoc HS is 12 months when stored in a dry environment in its original packaging. Proper storage conditions help maintain the product's effectiveness over time.

Yes, Renderoc HS is non-flammable and presents no fire hazard. However, it’s essential to follow the safety guidelines outlined in the Product Material Safety Data Sheet to ensure safe handling during application.
