APPLICATION INFORMATION

APPLICATION CONDITIONS

Temperature:
Air & Surface: 32°F minimum / 100°F maximum
Material: 50°F minimum / 95°F maximum

Relative Humidity: Can be applied at relative humidities up to 97%

APPLICATION PROCEDURES

BRUSH

• Use nylon or polyester brushes, do not over brush or apply too heavily.
• Heavy applications will slump on vertical surfaces.

SQUEEGEE

• Pour material out into a puddle and pull with the appropriate notched squeegee. 1/8" notch will yield approx. 1.5 gallons/100 square feet and the 3/16" notch will yield approx 2 gallons/100 square feet.
• After pulling with the squeegee, the material will have to be back rolled with a enamel short nap roller for uniform appearance. Cross hatch subsequent applications perpendicular to the previous layer.

ROLLERS

• Use 12, 18, or 24" rollers for back rolling large areas. Use 1/4 - 1/2" nap high grade synthetic heads with phenolic cores.
• Rapid rolling will splatter and may become airborne on higher buildings.

SPRAY — AIRLESS (for high volume)

• UR2650 two component material is best applied by airless spray with a siphon feed hopper or a Bink’s Hawk air assisted spray system.
• System will have to be purged with solvent after every 4 - 5 kits are sprayed to prevent equipment problems.
• Keep material above 50ºF prior to catalyzing in cold temperatures.
  
  Pressure: 3,000-4,000 psi 2-3 gallons/minute.
  Tip: 5.37 to 6.56 reversible
  Gun: Mastic or high volume heavy duty guns
  Line: 1/2" solvent resistant or 1/2" double braid hydraulic

PERFORMANCE TIPS

• DO NOT THIN
• POWER MIX BEFORE USING

RECOAT WINDOW

• Maximum intercoat bond for the UR2650 is within 48 hours. Work should be scheduled to be started and finished within this time frame. This is especially important in areas of submersion.

Damp conditions or water will foam the material. Do not apply if rain is immanent before proper film set can be established.

Please consult Coatings International for specific questions regarding the application of this system.

CLEANUP INSTRUCTIONS

• Clean spills and spatters and tools immediately with mineral spirits or xylene.
  
  
• Clean hands immediately after use with hand cleaner that works on asphalt or oils.
  
  
• After cleaning, flush spray equipment with xylene or mineral spirits. UR2650 must be flushed in standard spray equipment within 35 minutes.
  
  

SAFETY PRECAUTIONS

• INSTALLERS must read and understand all technical and informational literature for Tough Stuff UR2650, including the Material Safety Data Sheets (Part A/Part B), prior to using this product.
  
  
• For chemical emergencies, spills, leaks, exposure, or accidents in the U.S.: CALL CHEMTREC 24 HOURS A DAY / 365 DAYS A YEAR 1-800-424-9300.
