2. Apply Hiperhard liberally with a very soft broom or sprayer. If spraying,ensure you follow with a broom to work the product into the pores of the concrete. Apply Hiperhard liberally so that the concrete is saturated but without forming puddles. Approximate usage should be 5 litres per 25 m2 (1500 sq/ft per 5 gallon). I. Once the Hiperhard has dried,a second coat may be required if the concrete is very soft and still absorbent. Again,spread out any puddling with a soft broom. When applying one coat to hard concrete or two coats to porous concrete,the floor should always appear damp/wet for 15-20 minutes after the application of HiperHard. If this is not the case,another coat is required. II. Allow Hiperhard to dry completely before moving on to the next step. 6 – 12 hours is recommended as a minimum time to obtain a maximum cure of the Hiperhard product. The curing time will vary significantly with extreme temperatures – for cold environments longer and for warmer environments shorter. Note: We do not recommend removal of wet excess hardener with a squeegee or scrubber once it begins to gel off. For maxi- mum saturation and hardening of the concrete surface,it is recommended that the hardener be left in contact with the concrete until totally dry.

3. Remove excess cured/dry Hiperhard with CP1243 100 grit ceramic tools. I. Apply a thin layer of Hiperhard with a micro fibre applicator about 2-5 metres (5-20 ft) in front of the machine. Ensuring that the dried Hiperhard has turned to a gel-like state,proceed with honing the concrete. This will close any remaining micropores in the concrete surface and will make the ceramic tools more aggressive. II. If this thin layer is too wet when grinding,an inconsistent ’swirling’ in the flooring profile may be seen after the 100 grit ceramic diamond has passed an area. Ensure that any excess Hiperhard is removed completely. In its unreacted state,dry excess Hiperhard can cause the following problems if left on the floor: I. It will create brown/dark and unsightly patches in the floor when polished using dry resin polishing pads. II. If it comes into contact with water,it will reactivate and become very slippery. III. It will cause dull patches or ‘clouds’ in the finished product as Hiperhard will not polish up to the same level as the harder concrete.

4. Continue the polishing process with CP1244 200 grit ceramic tools. 5. Continue the polishing process with P1245 400 grit resin bond floor-polishing pads. I. You should notice a sharp refection developing at this stage. II. Some slightly higher wear of the P1245 400 grit resin bond floor-polishing pads may be experienced at this stage compared to the Premium finish or Commercial finish systems. 6. Apply 2 – 3 coats of Hiperguard penetrating sealer using a micro fibre floor sweeper,allowing drying time between coats. The floor should be fully saturated without excess to ensure all the pores are filled. The use of Hiperguard prevents contaminants from staining the floor and is highly recommended. However,in some circumstances,more so with the repair of previously highly contaminated surfaces,Hiperguard will show up previous staining beneath the surface due to the concrete pores already having a contaminant in them. 7. Leave to cure fully for at least one hour or until touch dry and then buff off any residual Hiperguard sealer using nylon buffing pads. Note: The surface can be ground and polished to tailor to different levels of exposed aggregates and non exposed aggregates and to high or low gloss levels by adding or omitting steps.
