SURFACE PREPARATION
The surface of the concrete was prepared by a combination of shot blasting and diamond grinding. All loose material, surface laitance, contaminants and or curing compounds were completely removed.
SKIM COAT
Due to the CSP left from the shot blasting the surface was then skimmed with Hychem E300SL blended with select silica sand. Due to the depth of the voids, the skim coat was applied three times in order for the product to level. Once dry the surface was then lightly abraded with a terrazzo grinder to remove any surface imperfections.
FIRST PIGMENTED COAT
The Hychem Supafloor resin and hardener were mixed together in the correct ratios using a mechanical variable speed helical mixer for 3 minutes. No solvent was added. The mixed product was then poured onto the floor spread by roller and back rolled to a uniform finish. The coverage rates were 0.5 – 1ltr / m2. Once dry the surface was then lightly abraded with a terrazzo grinder to remove any surface imperfections.
FINAL PIGMENTED COAT
Prior to blending resin and hardener and to improve the anti-slip the resin was filled with 12% by weight CA60# white aluminium oxide and then stirred. Then Hychem SF12FG resin and hardener were mixed together in the correct ratios using a mechanical variable speed helical mixer for 1 minute. Then add 10% solvent to assist with application and mix for a further 2 minutes. The mixed product was then poured onto the floor, spread by roller and back rolled to a uniform finish. The coverage was approximately 5m2 / litre.
HYCHEM NS – JOINTS RECUT & REPAIRED
The existing floor joints were resaw cut to approximately 10mm x 10mm and then filled with Hychem Hyflex NS pigmented a similar colour as the floor. Some floor joints were cut to 50mm in width due to the amount of expansion occurring.
RESULT & TESTIMONIAL
“The quick turnaround time meant the business could continue as soon as possible”
Bayset were able to provide an extremely hard-wearing, tough and durable surface with high mechanical strength. The completed flooring offers excellent resistance to chemicals and its smooth, high-gloss finish makes it easy to clean.
