TSP (Tri-Sodium Phoshate) is a powdered solution that serves as a pre-paint cleaner. It is most often used on previously painted surfaces as a heavy-duty degreaser. Sand your previously coated surface to degloss and roughen. Clean with TSP and allow to dry.

Bean E doo is a soy-based mastic remover. It is safe to use in any application and is used to remove the adhesive and mastic left behind on concrete after tile removal. Epoxies cannot bond to mastic. Black Mastic is extremely difficult to remove mechanically (with use of a grinder). Therefore it is recommended to use bean e doo. Once the bean e doo has been applied and the mastic has been scraped away. The substrate still needs to be cleaned to remove the residue of the bean e doo (use the etch n' clean solution or TSP). If the concrete is smooth, then it will need to be etched as well.  

Soy Gel is a soy-based paint, epoxy and urethane remover. It is safe to use in any application and is used to remove failing coatings. Once the coating has been removed, you will still need to make sure the concrete is clean and etched. Grind the concrete or use an acid wash to remove the residue of the Soy Gel to ensure a trouble-free bond.

Oil & Grease Emulsifier is a emulsifying process that permeates into voids, cracks or concrete surfaces converting the oily matter into a soapy solution permitting easy removal. Since oil contamination will prevent adequate adhesion of the epoxy, this is essential for unusually oily surfaces.
