SURFACE PREPARATION

Protect unintended surfaces from contact, including traffic and pedestrian areas below the project, electric tools, wood, furniture, fixtures and plants. Always test in a small, inconspicuous area prior to use.

DILUTION

Stone Restore HD can be used full strength or diluted. For brick surfaces or final restorative cleaning of rough limestone surfaces, dilute cleaner 1 to 9 with water. For horizontal concrete with stubborn red clay stains, start by using a 1 to 1 mix, then dilute as needed. Use undiluted to remove efflorescence.

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. Start at the bottom and work the product upward, spreading an even coat on the surface. Keep area moistened with Stone Restore HD to loosen the soil. Immediately rinse any 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, rinse with 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® 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 material
  • Stone Restore® CB2 For difficult to remove biological stains 
  • Stone Restore® PS For stubborn surface contamination on all types of polished stone
PRECAUTIONS

Use as directed. Stone Restore HD may cause discoloration on stone surfaces or affect adhesion of water repellants if used incorrectly. Never let this product dry on the surface. May damage limestone or travertine surfaces when used undiluted.
