I’ve got an exterior patio that is showing signs of slight deterioration and efflorescence. I think the substrate is made of flagstone. Do you have a product to help remove the stain and stop the deterioration? 

“Flagstone” refers to the style of stone more than its composition. Your floor could be made of limestone, sandstone, granite or slate. Our recommended product may vary depending on the specific type of stone comprising your floor, but most likely we would recommend testing Light Duty Concrete Cleaner for the efflorescence, and SLX100 Water and Oil Repellent or Natural Stone Treatment, depending on the stone type, to protect the surface from further damage. 

Please call us to make sure you’re getting exactly the right product for your specific floor conditions and circumstances.
