Description

Renderoc FC – Cementitious Fairing Coat

Renderoc FC is a ready-to-use, polymer-modified cementitious fairing coat supplied as a dry powder blend. On-site addition of clean water produces a highly consistent mortar, suitable for filling surface imperfections, blowholes, and thin render applications. Adding Nito bond SBR improves performance and durability.

Uses:
Renderoc FC cementitious fairing coat is designed for application in thin layers to produce a fair-faced appearance to concrete surfaces or masonry surfaces in readiness to receive a protective/decorative coating. Surface imperfections up to 3 mm in depth can be filled with the scrape coat application. Voids of greater depth should be separately filled as a prior operation, again limiting the material thickness to 3 mm. However, Renderoc FC can be used as blowhole filler up to 10 mm deep. Renderoc FC can also be used independently to infill surface imperfections and voids or to render large sections of concrete, brickwork or masonry at up to 3 mm thickness.

Advantages:

• Easy to use – no independent primer or curing membrane necessary.
• Excellent bond to the concrete substrate.
• Pre-blend to overcome site-batched variations – only the site addition of clean water is required.
• Contains no chloride admixtures.

Technical support:
Fosroc offers a comprehensive range of high-performance, high-quality construction products. In addition, Fosroc
offers a technical support service to specifiers, end-users and contractors, as well as on-site technical assistance in
locations all over the world.

Design Criteria:
Renderoc FC cementitious fairing coat is designed for vertical and overhead use to infill honeycombing and voids
up to 3 mm deep in the surface of concrete. It can also be applied as a render from a featheredge up to 3 mm thick
and as blowhole filler up to 10 mm deep. Consult the local Fosroc office for further information.

Specification clauses
Fairing coat
The fairing coat shall be Renderoc FC, a single component polymer modified cement-based blend of powders to which
only the site-addition of clean water shall be permitted. The material shall be capable of use without independent priming
and curing systems.

Application instructions

Preparation
Clean the surface and remove any dust, unsound material, plaster, oil, paint, grease, corrosion deposits or algae.
Roughen the surface to remove any laitance and expose the fine aggregate by light scabbling or grit-blasting. Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser. The effectiveness of decontamination should then be assessed by a pull-off test. Renderoc repair mortars require no additional preparation prior to the application of Renderoc FC. The cleaned areas should be blown clean with oil-free compressed air before continuing. All prepared areas should be thoroughly soaked with clean water immediately prior to the application of Renderoc FC. Any residual surface water should be removed prior to commencement.

Mixing

Care should be taken to ensure that Renderoc FC is thoroughly mixed. Small quantities (up to 5 kg) can be mixed
by hand using a suitable mixing drum or bucket. Greater quantities should be mixed using a forced-action mixer.
Mixing in a suitably sized drum using an approved spiral paddle in a slow speed (400/500 rpm) heavy-duty drill is an
acceptable alternative. For larger volumes, place 5.2 to 6.0 litres of cool drinking quality water into the mixer, and with the machine in operation, add one full 20 kg bag of Renderoc FC and mix for 3 to 5 minutes until fully homogeneous. For improved performance add 1.2 liters of Nito bond SBR or Nito bond AR into the mixer with the appropriate quantity of gauging water to achieve the desired mix consistency. Add one full 20 bag while the machine is in operation.

Note: That in all cases Renderoc FC powder must be added to water.

Application
Apply the mixed Renderoc FC to the prepared substrate by steel trowel from a featheredge up to a 3 mm thickness or
for filling blowholes up to 10 mm deep. It should be applied with the minimum of working and be allowed to partly set before finally trowelling to a smooth finish. If a very smooth
finish is required, a small amount of water may be flicked on to the surface of the Renderoc FC with a paintbrush prior to
final trowelling. Any friable material may be removed by light sanding after the Renderoc FC has cured. Do not proceed with the application when rainfall is imminent unless in a sheltered or protected situation.

Note: The maximum applied thickness of Renderoc FC is 3 mm from the depth of the imperfection to the finished surface. However, Renderoc FC can be used to fill blowholes up to 10 mm deep.
