THE PROBLEM
The existing resin flooring in the factory were aged, flaking and required refurbishment.

THE SOLUTION
We proposed the complete removal of the existing resin flooring by method of dust free diamond grinding prior to the application of a new high build resin flooring system. To ensure minimal disruption to our clients business operations all works had to take place out of hours over weekends.
Initially of the existing resin floors were removed using our remote controlled planetary diamond grinder. Inaccessible areas and edges were prepared using hand held diamond grinding equipment.
All surfaces were vacuumed clean and the moisture content of the slabs along with the climatic conditions tested for suitability and recorded. This was followed by the application of a pigmented moisture and oil tolerant epoxy primer to ensure excellent adhesion to the concrete.
Minor defects in the slab which became fully visible by the application of a pigmented primer were then filled using a twin component filler. Once cured these were sanded flush prior to the application of a heavy coat of high build epoxy resin at 0.5Kg/m2.
The following weekend our team returned to site to install demarcations. Because the epoxy applied the previous weekend had exceeded the overcoating window these areas had to be abraded using a rotary floor sander to provide a mechanical profile to ensure adhesion of the subsequent layer of resin flooring

High visibility yellow borders were then marked and installed using a fast curing Polyaspartic resin to enable two coats to be applied in one day. Bright colours such as yellow often have poor opacity, meaning that applying such demarcations in a single coat can be difficult.
Finally as per best resin flooring practice the expansion joints in the slab were reflected in the new resin finishes and sealed using a polyurethane jointing compound to prevent reflective cracking in the new floors. Something many other contractors omit either to reduce the cost or through lack of knowledge.
