Stone Restore CB2 should be used at a dilution rate of at least 3 to 1. For brick surfaces, dilute 1 to 9 with water. For concrete with stubborn stains, start by using a 10 to 1 mix, then dilute as needed.


Protect unintended surfaces from contact, including traffic and pedestrian areas below the project, electric tools, fabrics, furniture, fixtures and plants. Always test in a small, inconspicuous area prior to use. If product comes in contact with plant life, wash off leaves and soak root system well.


Wet intended surface prior to application. Have running water available to keep the surface damp. Apply an even coat of cleaner using a low pressure (40 psi max.), chemical-resistant sprayer. Keep area moistened with Stone Restore CB2 to loosen soil. Immediately rinse unintended surfaces, such as glass or frames.

For deep stains, allow the cleaner to penetrate the substrate for 10-20 minutes, but never allow surface to dry.
After product has saturated the stone, rinse using a pressure washer and a white, 40-degree tip or a green, 25- degree tip. Keep the tip as far away from the surface as possible. If a pressure washer is not available, use a brush to help loosen stubborn soils. For best results, use heated, deionized water.

Always rinse the area thoroughly to ensure no product is left behind. Multiple applications may be required for heavily soiled, porous or absorbent surfaces, and should be applied immediately after the initial application. Follow the same instructions for each application.
