MSDS Data Sheets

  1. Why do you have a sealer specific for Indian Sandstone? This is a very porous material so we created a more cost effective semi topical treatment that will seal and enhance the look of this stone.
  2. Why is there white residue on the surface next day after treatment? You have not followed the instructions and removed this white residue 20mins after application.  This is excess sealer that has not penetrated into the stone.
  3. What should  I use, if anything for ongoing cleaning after I seal the stone? The best ongoing maintenance cleaner to use is our Stontex Green to Clean.  Simply spray onto the algae stained dry surface on a dry day and then walk away.  No scrubbing or power washing required. Within a few days all organic stains will be gone. Stontex All in One Outdoor Cleaner / Stontex Green to Clean
