Practical Consumption

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 5412 or a coating system. The surface should be clean and dry during application.

Mix base and activator carefully with a filling knife, preferably not in the can but on a flat substrate alike a piece of hardboard. Apply a slight over-amount of the Epoxy Putty with a filling knife or trowel; after drying reshape the surface by abrading the excessive amount.
