Silicone Sealer Stone & Grout Meister 01 Sep 2009 02:17 EDT

I'm getting ready to clean and seal about 400 sq ft of ceramic floor tile. The grout appears to have a sealer on it, in some areas the sealer has broken down. I think the sealer is a silicone base. Is their a quick and easy way to determine if it is a silicone sealer? How long does a silicone sealer last under normal foot traffic in a residential setting using the proper cleaning products compared to a penetrating sealer? Could a fluoropolymer penetrating sealer be applied to the grout without stripping the silicone sealer? Does anyone know of a silicone sealer that I could buy off the shelf at a big box store? Thanks......
