Product Application

Surface Preparation: Carefully clean up with a wet mop or HEPA vacuum.

Surface Repairs and Cleaning: Lagging that is torn, ruptured or delaminated should be repaired with:

  1. Patching Cement: Mix cement with water and cap all exposed ends and voids.
  2. Lag Kloth Water-Activated Repair Cloth: Lag Kloth should be dipped in water and applied to the asbestos containing material. Upon completion of repairs, prepare the surface for the application of Lag Kote II. Thoroughly remove all dust and dirt that has accumulated on lagging or covering, use a vacuum with a HEPA filter specifically designed to capture hazardous dust and waste or wipe surfaces with a damp cloth. Do not air clean surfaces; this could increase asbestos exposure.

Application Tools: Apply Lag Kote II with brush, roller or airless spray equipment.

  • Brush: Synthetic, nylon or polyester bristle
  • Roller: Synthetic Fiber 3/8” nap or longer
  • Spray Settings:  Pressure: 2200-2700 P.S.I. Tips: .017 to .021 tips

Mixing: Lag Kote II may be diluted by adding up to 10% water. Prior to application, stir Lag Kote II thoroughly to achieve a uniform consistency. Lag Kote II can be tinted to pastel colors.

Select a brush, roller or painter’s mitt for convenient application to the ACM. Apply 1-2 coats of Lag Kote II to the desired film thickness. Minimum film thickness may vary with desired results and type of application.

Cleanup: Tools and drippings should be cleaned with warm soapy water before coating dries. Follow equipment manufacturer’s directions to clean spray equipment. Dispose of all waste according to current local, state and federal regulations.

Precautions: Store in a dry place at temperatures between 40°F (4.5°C) and 90°F (32°C). When applying with a sprayer, wear a NIOSH approved respirator with any R, P, N or HE filter. Approved respirators must be used to prevent inhalation of asbestos fibers that may be present in the air. Protective clothing should be worn. Careful consideration must be given to all EPA, OSHA, federal, state and local regulations in effect prior to the application of this product.
