Material Preparation
- Stir well, Do Not Thin.
- Apply only to clean, dry, oil-free surfaces.
- Keep container closed when not in use.
Application
- Apply the SPARK-FAS® WB Adhesive to the surface uniformly at 250 – 400 sq. ft. per gal. (6.1 – 9.8 m2/l).
- While still wet, press the insulation into place, making sure that complete contact is made with applied adhesive.
Brush/Roller
- Use clean equipment suitable for water-based paints. Apply SPARK-FAS® WB Adhesive to metal surface uniformly. Press insulation into place, making sure that complete contact is made with applied adhesive.
Spray
- SPARK-FAS® WB Adhesive can be easily applied, with a paint-like spray pattern, using a variety of conventional air atomizing and airless spray equipment. The following equipment combinations are suggested:
Spray Gun Model Fluid Nozzle Air Cap Fluid Pressure Atomization Pressure
Binks 62 63 66SD 25-25 psi 60-70 psi DeVilbiss JGA FX 770 20-25 psi 60-70 psi - For spray equipment information, please contact your spray equipment supplier. Average viscosity range: 5000 - 8000 cps. Corrosion resistant pumps and fittings are suggested.
Clean Up
- To clean up, use warm soapy water if still wet. When dry, use mineral spirits (flammable) or chlorinated solvent (non-flammable).
