We recommend the use of one of Presto's stone protective treatments to protect the newly restored surface for years:
Stone Restore A+ should be used at a dilution rate of at least 3 to 1. For light stains, dilute 1 to 9 with water. For horizontal concrete with stubborn oil stains, start by using a 3 to 1 mix, then dilute as needed.
Wet the 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 A+ to loosen soil. Immediately rinse any unintended surfaces, such as glass or frames.
For deep stains, allow the cleaner to penetrate into the substrate for 10-20 minutes, but never allow surface to dry.
After product has saturated the surface, 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. Always rinse area thoroughly to ensure no product is left behind.
Multiple applications may be required for heavily soiled, porous or absorbent surfaces. Apply immediately after initial application. Follow the same instructions for each application. For best results, rinse with heated, deionized water.
Situations including various stone types or different natured stains may require multiple products. Presto’s stone cleaning line includes:
