Description & Uses

Fosroc Renderoc FC is a ready-to-use blend requiring only the addition of clean water. It is designed for vertical and overhead use to infill honeycombing and voids.

• Primary Use: To produce a fair-faced appearance on concrete or masonry surfaces in preparation for protective or decorative coatings.

• Application Depth: Fills surface imperfections up to 3 mm. Deeper voids should be filled in a prior operation or using Renderoc RP252.

• Compatibility: Fully compatible with structural/non-structural concrete (20-45 MPa) and other Renderoc mortars.

Key Advantages

• Low Permeability: Polymer modification ensures resistance to water, carbon dioxide, and chlorides.

• Strong Bond: Excellent adhesion to concrete substrates.

• Ease of Use: Single component (pre-bagged) to eliminate site-batching errors; requires only water.

• Chloride Free: Contains no chloride admixtures.

• Fast Application: Can be applied quickly and efficiently.

Application Instructions

1. Preparation

• Clean the surface of dust, oil, paint, grease, algae, and unsound material.

• Roughen the surface (scrabbling or grit-blasting) to remove laitance and expose fine aggregate.

• Saturate: Thoroughly soak the area with clean water to achieve a Saturated Surface Dry (SSD) condition immediately before application.

2. Mixing

• Ratio: 6.5 to 7.0 liters of water per 25 kg bag.

• Method: Use a forced-action mixer or a slow-speed drill (400/500 rpm) with a spiral paddle (MR4).

• Procedure: Pour water into the mixer, add powder, and mix for 3 to 5 minutes.

• Important: Do not re-temper with extra water after mixing.

3. Curing

• Moderate Conditions: No specific curing required.

• Harsh Conditions (Wind/Heat): Cure immediately after finishing.

• Recommended Method: Spray Nitobond AR as a continuous film or use polythene sheeting taped at the edges.

Storage

• Store in dry conditions in original unopened bags.

• High humidity or temperature may reduce shelf life to less than 6 months.
