This Guide discusses techniques and procedures to select and apply resinous coating systems over concrete floors. These thick-film systems (greater than 500 micrometers [µm] [20 mils]) include self-leveling systems, slurry systems, broadcast systems, mortar systems, fabric-reinforced systems, spray applied systems, and non-waterproffing and underlayment membranes. Application of thin-film coatings (less than 500 &microm; [20 mils]) and sealers, terrazzo flooring, membrane systems designed for waterproofing, and primary and secondary containment systems is beyond the scope fo this Guide.
