I have carried out a pre-application trial on my stone with STAIN-PROOF Original™ and waited 24 hours for it to cure but olive oil still leaves a mark, why?
This sometimes happens on very porous stone and can be over come by varying the application method. The surface needs a pre-seal to hold the STAIN-PROOF Original™ closer to the surface. Apply the first coat, and after 10 minutes wipe off the excess. Allow the product to cure for a minimum of one hour (24 hours is even better!). Then apply a second coat of STAIN-PROOF Original™ and polish off the excess after it becomes touch dry or a minimum of 10 minutes. Please note that most Dry-Treat sealers are reactive and therefore take over two weeks to fully cure.
