- Product Highlights
- Fire Resistive Lagging Adhesive and Coating when applied to the longitudinal and butt laps of lagging fabrics provides strong adhesion to hold the lagging in place.
- An application of a coat of Fire Resistive Lagging Adhesive provides resistance to fire, water, vermin, oil and grease.
- Fire Resistive Lagging Adhesive and Coating 81- 42 contains no asbestos, lead, mercury, or mercury compounds.
- It is formulated without halogenated (chlorinated) raw materials.
- Fire Resistive Lagging Adhesive and Coating 81- 42 is approved by the U.S. Coast Guard under 164.012.

- Preparation and Application Information
Material Preparation
- Do Not Thin.
- Apply only to clean, dry surfaces.
- Keep container closed when not in use.
Application
- Apply a tack coat of Fire Resistive Lagging Adhesive and Coating at 75 to 80 sq. ft./gal. (1.8 - 2.0 m2 /l).
- Immediately imbed the selected lagging fabric into the wet adhesive.
- Smooth to avoid wrinkles and overlap seams by at least 2 inches (5 cm).
- Immediately apply a sizing coat of Fire Resistive Lagging Adhesive and Coating at 75 to 80 sq. ft./gal. (1.8 - 2.0 m2 /l).
Top Coating
- If 81-42 is to be top coated with anything other than an alkyd enamel conforming to DOD-E-24607 as specified in Mil-A-3316C, the user must confirm by his own tests that the products are compatible and that the final results are satisfactory.
Brush
- Use clean paintbrushes. Apply full coat in uniform thickness.
Dip
- On long runs or large surface areas, lagging fabric may be dipped to achieve greater speed and labor economy.
- Dipped lagging cloths and tapes must be applied to the insulation while lagging adhesive is still wet.
Spray
- Fire Resistive Lagging Adhesive and Coating may be spray applied using conventional air atomized or airless spray equipment.
- For spray equipment information, please consult Airless Spray Recommendations or contact your spray equipment supplier.
- Average viscosity range: 30,000 - 40,000 cps.
Clean-Up
- Use fresh water to clean brushes and equipment before product dries.
- Dry product may be removed with hot soapy water or strong solvent such as chlorinated solvent (non-flammable) or mineral spirits (flammable).
