A blue-chip client on a water treatment in Coleshill required an anti-slip floor lining for an acid fill point. The Area would need to contain and be resistant to 98% sulphuric acid whilst also being able to cope with the load of articulated traffic.
The only coating available that would offer this would be a chemical resistant epoxy coating system.
The floor area consisted of a new concrete slab with kerb stones. For the epoxy coating to adhere properly the area would need to be grit blasted, thus gaining adhesion and removing laitance from the concrete. Due to the sensitive area, wet blasting was chosen. Once blasting was complete all the sludge was cleaned, and the newly blasted slab was jet washed and left to dry.
Once the slab had dried the site team applied a moisture tolerant solvent free epoxy primer at 100 microns to the entire concrete slab. This was left to dry.
Fabric bandage was applied to all expansion joints and edges and bedded in with novolac epoxy. Once dry the site team applied a full coat of red epoxy novolac to the entire primed area and over the banding. Whilst they were applying the red coat an operative wearing spike shoes placed aggregate over the top of the coated areas. The whole 1st coat was then left to dry.
The area was finely swept to remove any loose aggregate before applying the final coat of novolac epoxy to the entire area. The entire project took 5 days to complete.
