How to Remove Patio Stain and Revitalize Your Stone Patio
Exterior stone patios are constantly exposed to moisture, shade, soil contact, and airborne debris, conditions that lead to organic buildup, surface darkening, and recurring stains over time.
TERSO MR® provides professional condition correction and periodic treatments tailored to your stone type, installation method, and site environment. Our approach addresses mold, moisture, and drainage to help maintain a cleaner, more consistent patio season after season.

Scope may include:
-
Gentle removal of organic buildup from stone and joints

Because exterior environments continually introduce moisture and debris, periodic service is expected for ongoing performance.
High-pressure washing is not recommended as a routine maintenance method.
