Fosroc TG 25kg Renderoc

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 TG is a ready-to-use blend of dry powders that, when mixed with clean water, forms a medium-weight repair mortar. It is designed for general-purpose concrete and masonry repairs, providing excellent thermal compatibility and durability in various conditions.

Renderoc TG is suitable for a variety of applications, including vertical and overhead repairs, filling voids greater than 10 mm, and restoring surfaces in hot climates. Its formulation allows for high build without the need for formwork, making it efficient for large-scale repairs.

The product offers several advantages, including high build capability without formwork, low permeability to protect against carbon dioxide and chlorides, and excellent bond strength to concrete substrates. Additionally, it is shrinkage compensated and contains no chloride admixtures, enhancing its durability.

Renderoc TG is specifically formulated to perform well in hot climates. It incorporates anti-dessication additives that help maintain workability and minimize water demand, ensuring that the mortar remains consistent even under challenging environmental conditions.

Renderoc TG can be applied in thicknesses up to 70 mm in vertical applications and 60 mm in overhead applications. For optimal results, it should be applied in layers if thicker sections are required.

To prepare Renderoc TG, simply mix the dry powder with clean water according to the manufacturer's guidelines. It can be applied using either a wet or dry spray technique for fast and effective repairs.

Yes, Renderoc TG is designed with environmental considerations in mind. Its low permeability helps protect against harmful substances like carbon dioxide and chlorides, contributing to the longevity of structures while minimizing environmental impact.

When using Renderoc TG, it is essential to wear appropriate personal protective equipment (PPE), such as gloves and masks, to avoid skin irritation and inhalation of dust. Always refer to the product's safety data sheet (SDS) for specific handling and safety instructions.
