SENTINEL 538 Smoke & Odor White Encapsulant

Sentinel 538 Sealer Encapsulant is a professional strength, low-odor, fast-drying sealer encapsulant used to seal and trap odors commonly found on restoration projects like smoke and other odors. Sentinel 538 works great as part of a two-part system and should be used after affected areas have been cleaned and treated with Sentinel 531 Smoke & Odor Counteractant or Sentinel 522 Smoke & Odor Cleaner & Destroyer.

Before using Sentinel 538 Sealer/ Primer Odor Encapsulant to rid the space of unwanted odors, first clean dirt, grease, grime, smoke, and soot  from floors, walls, ceilings, and other surfaces.

 Preparation: Surfaces must be clean, dry, and free of loose debris. For best results, the application area should be at least 60ºF with humidity levels below 70%. Shake or stir 538 thoroughly before using to ensure proper coverage.  Coverage rates range from 200 - 400 square feet per gallon, depending on the porosity of the surface being sealed.    

 DIRECTIONS FOR USE: (FOR PROFESSIONAL USE ONLY.)

1. Apply Sentinel 538 using a brush, medium nap roller, or sprayer. Apply a thin uniform coat.  Allow 538 to dry thoroughly (a minimum of 120 minutes).  
   1. When spraying 538, mix contents thoroughly and use a 0.020 tip.  
2. If necessary, a second coat can be applied after the first coat is completely dry.  
3. If spraying 538 in HVAC ducts or systems, allow to dry for 2 hours before recirculating fresh air.  
4. Fresh air should be carefully inspected for odors before ventilating into occupied spaces.  
5. The use of a NIOSH-approved respirator is recommended when exposed to spray mists or in areas of poor ventilation.
