The chemical bond of a resin coating to a substrate is crucial to the success or failure of a floor coating system.
You can achieve a good bond by completing appropriate surface preparation through diamond grinding, scarification or enclosed shot-blasting. On concrete substrates, these methods of preparation clean the substrate and create a open textured profile which the resin coating can adhere to.
If appropriate preparation is not completed then the floor can de-bond from the substrate causing the coating to break away from the substrate. If there is a chip or crack in the coating down to the bond layer, this process can speed up as contaminants get underneath the coating and cause mass delamination and failure.
To avoid failure it is important that correct preparation is completed and that you specify the right floor coating thickness for your environment.
