RonaBond EasySkim FC is a pre-packed fairing coat mortar which is applied as a skim coat in thicknesses up to 3mm to provide a smooth, hard finish to damaged, blemished and repaired concrete surfaces.

RonaBond EasySkim FC is used as a levelling mortar prior to the application of protective coatings or paints. The material is supplied in pre-blended form.

Features & Benefits

• Conforms to BS EN 1504-2
• 1mm - 3mm application thickness
• Fair-faced finish on walls and soffits
• Covers minor blemishes
• Apply by trowel
• Apply prior to application of surface coating

Preparation

Careful preparation of the substrate is required before application. The substrate must be clean, sound and free of dust, algae, laitance and deleterious material.

Surfaces must be sufficiently stable, sound and strong to receive the RonaBond EasySkim FC.

Surfaces should be repaired or made good as required. Fill large blemishes greater than 3mm deep using RonaBond Concrete Repair Mortar or RonaBond HB40 to prevent them showing through the finished RonaBond EasySkim FC.

Damp the prepared surface with clean water and remove any excess.

Mixing

Mix using a slow speed drill fitted with a suitable paddle attachment or a forced action mixer; do not use a free fall mixer. Pour approximately two thirds of the gauging liquid into the mixing vessel and gradually add the powder component.

Mix for 2 minutes and add sufficient of the remaining gauging liquid to achieve the desired consistency. Mix for a further 1 minute.

Application

Apply RonaBond EasySkim FC with a steel float ensuring total contact. . Trowel marks may be removed and light texture produced using a dry sponge. This must be carried out before the material hardens.

Application in strong sunlight or windy conditions should be avoided but the use of a mist spray will prevent over-rapid drying if this is unavoidable.

Anti-Carbonation Coating

To improve carbonation resistance of the concrete RonaBond EasySkim FC should be covered with a protective coating such as RonaBond Crack Bridging Anti-carbonation Coating or RonaBond Anti-carbonation Coating WB.

Over coating can be carried out within 24 hours at 20°C of applying RonaBond EasySkim FC provided the surface is sufficiently hard and dry.

Careful selection of the surface coating will provide additional protection and prolong the life of the underlying concrete. Refer to Rawlins technical on 0113 2455450 (option 2) or send a message to [email protected]

Working Temperatures

RonaBond EasySkim FC can be used in most weather conditions and in a wide temperature range, typically from +3°C to 25°C and above.

Note that at high ambient temperatures the working time of the mix will be reduced; it will be increased at lower temperatures. Do not attempt to apply at material, air or substrate temperatures above 25°C to avoid rapid drying of the surface.
