RECOMMENDATIONS

We recommend the use of one of Presto's stone protective treatments to protect the newly restored surface for years:

• Leach Stop® – Mineral Leaching Mitigation Treatment™

• ElaSticone® – Silicone sealer for concrete, masonry and stone surfaces

• ElaSticone® GSX – Silicone with graffiti protection for concrete, masonry and stone surfaces

• Protect-A-Stone® – High-performance oil protection for stone surfaces

• ReJuviSeal® – Rejuvenating oil protection for stone surfaces

SURFACE PREPARATION 

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. 

APPLICATION 

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. 

Situations including various stone types or different natured stains may require multiple products. Presto’s stone cleaning line includes:

• Stone Restore® HD For difficult to remove mineral stains caused by efflorescence, rusting, red clay, iron and more 
•  Stone Restore® NC For general cleaning of sensitive stone surfaces that require a neutral cleaner 
• Stone Restore® A+ For heavy stains caused by oil, grease, grime and environmental pollution 
• Stone Restore® CT A multi-purpose stone cleaner that removes a variety of stains from all types of stone materials 
• Stone Restore® PS For stubborn surface contamination on all types of polished stone

PRECAUTIONS 

Stone Restore CB2 may cause discoloration on some stone surfaces or affect adhesion of water repellants if used incorrectly. Never let this product dry on surface. Do not mix this product with any other chemicals.
