If I am hijacking this thread please let me know. However I have a somewhat related situation.The shop I use was inherited, and my Dad and brother poured a concrete floor but left a rough finish. In fact, there are places where some of the aggregate (sp?) shows. This makes vacuuming and sweeping difficult. Is there a product (topcoat?) that could be poured to alleviate this somewhat and still be durable? As usual, any suggestions are welcomed and appreciated! By the way, the concrete is gray and I still have trouble seeing a nail or screw!
