I looked at a slate shower tonight that a cleaning lady used a product in a blue bottle to try and clean it. Anyway the cleaner left a white film and run marks on the slate tile. Not a big deal cleans up with honing powder and a carbide brush on an angle grinder. The installation is about 15 years old, the installer applied a water base topical finish to the slate which has worn off below the water line. What’s the best finish to put on slate in a shower ? I don’t like the idea of putting a topical finish on the slate, especially in a shower. It would be easy to maintain, but if had to be the removed it could be a real task. The home owners want something that will bring out the colors and give it a wet look ……. In the past I’ve used SBS Sealer by Aldon http://www.aldonchem.com/pr-sbs-sealer.htm on exterior slate installations but not in shower. A color enhancer is another option but the slate has a lot of texture and an enhancer would not seal those areas. Any recommendations would b greatly appreciated ……………. Thanks
