Hychem SupaFloor — Multi-Purpose Pigmented Epoxy Flooring System

Prior to the application of HYCHEM Supafloor, the substrate must be thoroughly prepared.

• The substrate must be clean and firm with a minimum compressive strength of 25MPa and a minimum surface tensile strength of 1.5MPa.
• The moisture content of the concrete must be below 5%.
• New concrete must be allowed to cure for minimum 28 days.
• In most instances, mechanical preparation is required.
• All dust, loose and friable material must be completely removed from all surfaces before application, preferably by vacuum.

It is important to note that even when the application environment is warm, products which have been stored in cold or cooler conditions should be pre-conditioned, ideally to 20-25°C, to ease mixing and application and help avoid other potential issues such as amine bloom or blushing. Applying a cold product in a warm environment is not recommended.

Add pigment pack to part A resin and mix thoroughly with a low-speed mechanical stirrer until complete uniformity is achieved. Add part B hardener and mix for 3 minutes ensuring the sides of the vessel are scraped to ensure no unmixed material.

Apply the mixed product at approximately 5-7 m²/L per coat over low porosity surfaces or 2-3 m²/L per coat over high porosity surfaces e.g. over a porous screed or where the base has been broadcast with aggregate. To assist workability HYCHEM Supafloor can be diluted using Industrial Alcohol or Xylene at a maximum rate of 10-15% by volume where necessary. NB. this may affect pot life and cure times slightly.

Mix Part A resin, Part B hardener and the pigment together for 1 minute before adding all or part of the ESL fillers supplied depending on the application temperature and the thickness required. Continue mixing slowly to minimise air for a further 2 minutes until a uniform consistency is achieved. Where multiple mixes are required, each mix should be timed so no variations exist.

Pour the mix onto the double primed substrate and spread with a flat or notched trowel or pin rake. Ensure the material is spread evenly and to the required thickness. Roll with a spiked roller to eliminate air bubbles.

Pour the mix onto the primed and fully sealed substrate and spread with a flat or notched trowel or pin rake. Roll with a spiked roller to eliminate air bubbles. For sloping floors, additional aggregate may be required to reduce flow. Broadcast selected aggregate to refusal into the un-cured material. Allow to cure, vacuum off loose aggregate, then apply HYCHEM Supafloor as for roller application.

Temperature and the surrounding atmospheric conditions will play a part in the curing process of all resin products. Under conditions of low temperatures and high humidity the final cured surface finish can be adversely affected, potentially resulting in poor gloss retention, discoloration over time, poor overcoat ability and inter-coat adhesion. Quite often these conditions will result in the formation of a white film over the surface, often evident after contact with water. If this occurs, the existing coating will need to be abraded to completely remove the affected surface to ensure the adhesion of subsequent applications. In some cases, partial or complete re-priming may be necessary. Attention also needs to be paid to the substrate temperature, which should be at least 3-5 °C above the dew point during the curing phase. Industry standards recommend the accurate recording of environmental conditions such as substrate and air temperatures, humidity levels and dew point readings during both the application and curing processes. Full material warranties cannot be provided unless all the relevant data has been recorded accurately. If in doubt consult the HYCHEM technical department for advice.

Wear appropriate personal protection equipment. Gloves, eye protection, mask and overalls should be used during mixing and application.

Minimum 12 months from date of manufacture when stored under shelter at 25°C in the original un-opened container.

The packaging must be stored properly in original, unopened and undamaged sealed packaging, in dry conditions at temperatures between 5°C and 30°C.

HYCHEM Supafloor is supplied with pigment. As with most epoxy finishes, surface yellowing may occur on exposure to UV light from the sun or an artificial source. Any such discolouration has no effect on the performance of the product.

• Coatings and overlays containing water must not be applied directly to HYCHEM Supafloor resin unless a sufficiently porous mortar has been installed or it has been fully broadcast with dry aggregate e.g. quartz or silica sand.
• Ensure consumption of material is uniform to achieve proper appearance, texture and consistent performance.
• Ensure the material is mixed and stirred properly. Incorrect mixing can lead to performance issues.
• If heating is required do not use gas, oil, paraffin or other fossil-fuel heaters. Use only electric-powered warm-air blower systems.
• At low temperatures and low humidities (< 40% relative humidity), curing and recoat times will be affected.
