RAINSTOPPER^¨ 1750W - CLEAR

I. PRODUCT DESCRIPTION

RAINSTOPPER^¨ 1750W - Clear is a microemulsifiable concentrate based on silanes and alkoxysilanes. When mixed with water, a microemulsion is produced. This diluted form will impart water repellency to absorbent mineral surfaces.

Important features of RAINSTOPPER^¨ 1750W - CLEAR:

• A clear concentrate that is solvent and water free
• A viscosity comparable to water
• Immediate miscibility with tap water without extensive mixing.
• V.O.C. compliant (less than 400 gms per liter minus water: ASTM D5090)
• Complies with Series 11 NCHRP 244 Report
• Meets SSWIIOC Federal Specification

II. INSTALLATION

The RAINSTOPPER^¨ 1750W - Clear may be roller or spray applied. A low pressure spray unit (20-25 pounds per square inch) or Hudson sprayer. Achieve a flooding condition with rundown. Multi-applications should be wet on wet. Before application, be sure the surface is clean and free of environmental dirt, efflorescence, form oils, curing compounds or any other foreign matter that can affect the penetration of RAINSTOPPER^¨ 1750W - Clear. Surface to be treated should be uniformly wet or dry.

III. CLEANING METHOD

Clean up wet overspray on glass, metal or painted surfaces immediately with water, otherwise, RAINSTOPPER^¨ 1750W - Clear adheres tightly to surfaces when cured. Spray or roll equipment while wet must be cleaned up with water immediately.

*RAINSTOPPER^¨ 1750W-Clear test results based on a dilution of 4.5 parts water to 1 part RAINSTOPPER^¨ 1750W by volume. Application based on coverage of 125 sf/gallon. NOTE: Various degrees of water repellency can be achieved at higher dilution values.

V. LIMITATIONS

• Masonry should be cured a minimum of 28 days before application.
• Rain or snow is not imminent.
• Surface should be free of foreign matter and not frozen.
• When mixed with water, the blend should be used within 24 hours. Longer storage time with the water blend can affect penetration properties.
• Keep containers sealed to eliminate moisture intrusion.
• RAINSTOPPER^¨ 1750W Clear is for above grade only.
• Allow to cure under ideal conditions for a minimum of 72 hours if an oil based system is to be applied (maximum 100¡F).
• Environmental temperatures should be between 45¡F and 100¡F.
• Do not store near excessive heat or flame.
  (Flash Point = 77¡F).
• During application use splash goggles, rubber gloves, protective apron and vapor respirator to conform with the following HMIS values:
  Health = 3
  Flammability Hazard = 3
  Reactivity Hazard = 1
  Personal Protection = H
• Storage: Up to six months in sealed containers stored at 45¡F to 100¡F.
