[QUOTE="alabama, post: 259829, member: 2218"] I assume what you have is a concrete slab. Portland “Cement” is an ingredient in concrete. The best way I know to roughen the surface is to chip away the laitance that formed on top while it was finished. It is made up of mostly cement and water that is floated to the top while the large and small aggregate are patted down to get the smooth finish. Most any type of chipping hammer will work. Just chip away the top surface. If you can build, a “HOT” fire on the slab the expanding air bubbled in the top surface will fracture way the top surface the easy way. You could use a torch and heat a small spot at a time and chip away the surface that way. You could also bolt down a grid of welded together number 6 rebar. I would say weld a flat mat of rebar on 8 inch centers and bolt it down every 16 inches or so. [/QUOTE]
