Preparation and Application Information

Material and surface preparation

  • Stir well.
  • Do not thin.
  • Apply only to clean, dry surfaces.
  • Ensure that all surfaces are free of all wax, grease, oil, dirt, rust, mold and other surface contaminants.
  • Following complete cleaning procedures, sanitize the entire surface with foster® 40-80 first defense™disinfectant, following manufacturer’s directions.
  • Patch any large voids or defects.
  • On painted surfaces, remove all flaking, loose or chalking material.
  • Sand all glossy painted surfaces using 220-grit sandpaper to roughen the entire area.
  • All rusted, metal surfaces must be primed before application.
  • Although foster® interior defense™(40-50) may be applied directly onto cleaned, unrusted, galvanized surfaces, it is recommended that these surfaces be primed.

Application

  • Apply interior defense™to all surfaces at a rate of 250 – 400 sq. Ft./gal. (6.1 – 9.8 m2 /l) to create a uniform film on the surface.
  • Spraying or brushing will give the smoothest finish.
  • For optimum performance, maintain uniform recommended coverage.
  • Porous or uneven surfaces will require more material.
  • Spray equipment: interior defense™can be applied with virtually any type of airless spray equipment on the market today.
  • Reversible cleaning 0.015” – 0.017” spray tips are recommended for optimum application.
  • The average viscosity range is 2,500 – 8,000 cps.

Important

  • When applying interior defensetm, proper personal protective equipment must be used.
  • Necessary equipment and clothing are the same as would be used when applying other water-based paints or coatings.
  • Ensure that the application area is well-ventilated during application to avoid buildup of vapors.
  • Appropriate respiratory protection must be used when applying by airless spray.
  • Use of a respirator with organic vapor cartridges is suggested if adequate ventilation cannot be achieved.
  • After application of interior defensetm, continue to ventilate the area with fresh, dry air to ensure proper drying of the coating and to exhaust odors.
  • Ventilation should be continued until the odor is reduced to an acceptable level for building occupants.
Cleaning Information
  • Use fresh water to clean equipment before product dries.
  • Dry product may be removed with undiluted pine oil or citrus-based cleaners or with nonflammable chlorinated solvents.
