Staroxy FC SL 1000 and 2000

Surface preparation: -
The surface of concrete floors must be dry or slightly damp, clean and sound and have no crumbling or detached portions. The concrete slab must have a minimum compressive strength of 25 N/mm² and a minimum tensile strength of 1.5 N/mm². The strength of the substrate must also be suitable for its final use and the types of load to which it will be subjected.
The level of moisture in the substrate must be a maximum of 4% and there must be no capillary rising damp (check by testing it with a sheet of polythene).
The surface of the floor must be prepared with a suitable mechanical process (e.g. shot blasting or grinding with a diamond disk) to remove all traces of dirt and cement laitance and crumbling or detached portions, and to make the surface slightly rough and absorbent.
Before applying the coating, remove all dust from the surface with a vacuum cleaner. Any cracks must be repaired by filling them with Starocrackfill, while any deteriorated areas of the concrete must be repaired with Staroxy Epocrete from the Stanrose Repair Mortar line. Before applying Staroxy FC SL 1000, remove all traces of dust from the surface with a vacuum cleaner.

Other Surfaces
The coating may be used on other substrates. Please contact Stanrose Envirotech India Pvt. Ltd. for more information.

Priming
The concrete surface after proper and thorough surface preparation has to be primed with Staroxy 103 MOT Primer. The primer is a solvent free epoxy resin system. It is designed for better adhesion with the substrate and the flooring system. The primer should be mixed in the given proportions supplied. The entire contents of the hardener should be poured into the base and should be mixed using a low speed drill machine with an attachment for about 3 minutes at (150-200 RPM) to get a homogeneous mix. Once mixed, the primer should be applied immediately on to the prepared concrete surface. After priming, the surface has to be kept for drying - approximately 12-16 hrs. depending on the ambient temperature before proceeding to lay Staroxy FC SL 1000. Depending upon the surface and flooring thickness, immediately after applying Primer, fully broadcast the surface with Quartz 0.5 while it is still wet to ensure the next coat of resin adheres perfectly. When the primer has hardened remove any excess sand, sand the surface and remove the last grains of sand with an industrial grade vacuum cleaner.

Mixing and Application:
The two components which make up Staroxy FC SL 1000 must be blended together. Pour component D (pigment) into component A (resin) and mix for at least a minute with an electric mixer. Then pour Component D (pigment) in the mixture at low speed to prevent entraining air into the mix (300-400 revs/min) until it is completely blended and then do the same process to mix component B (hardener). Do not mix the product for too long to prevent entraining too much air into the mix.
Pour the mix into a clean container and briefly mix again. Apply a coat of 1 mm thick on the floor treated previously with Primer with a straight or notched trowel. Using a straight trowel helps reduce the marks made by the troweling action. Apply the mix within the pot life indicated in the table (refers to a temperature of +20°C). Higher surrounding temperatures will reduce the pot life of the mix, while lower temperatures will increase its pot life. Go over the surface with a spiked roller several times while the product is still wet to even out the thickness of the coat and to remove any air entrapped in the product.

Method of Application
Topcoat is normally spread with a trowel and back-rolled with a 3/8" medium nap roller. Care should be taken to minimize the entrapment of air caused by over rolling.
