Stone Sealer #2 and Stone Sealer #3 are water based, odorless, low VOC sealers for all types of natural stone surfaces including marble, granite, slate, limestone, travertine and sandstone. The sealers provide a natural or invisible finish when cured and makes the stone surface stain and water repellent.
The difference between the two sealers is the chemistry where Stone Sealer #2 is a silicone polymer and Stone Sealer #3 is fluoropolymer. Under normal use conditions the two sealers have similar performance characteristics for stain repellency. A difference can only be seen under severe or abuse conditions the Stone Sealer #2 would exhibit better repellency against water based stains and Stone Sealer #3 would perform better against oil based stains.
