Theoretical: 1.3 kg/m² per 1 mm thickness. 
Practical: Practical coverage depends on many factors such as porosity and roughness of the substrate and material losses during application. 

Surface Preparation

Remove oil, grease and all other surface contaminations by alkaline or high pressure (steam) cleaning. Remove loose and unsound concrete until a sound surface is obtained. New concrete or masonry should dry and cure for at least 30 days before applying Rust-Oleum Light-Weight Repair Mortar 5140 or a coating system. Rusted reinforcement bars should be prepared by blasting or other suitable methods; apply the appropriate Rust-Oleum Epoxy primer mixed with dry quartz sand; after drying, apply Rust-Oleum Light-Weight Repair Mortar 5140. The surface should be clean and dry during application.
