Preparation and Application Information

Material Preparation

DO NOT THIN. Apply only to clean, dry, oil-free surfaces. Keep container closed when not in use.

Application

1. Apply a tack coat of LAGFAS® Adhesive/Coating at 80 – 90 sq. ft./gal. (2.0 – 2.2 m2 /l).
2. Immediately embed the selected lagging fabric into the wet adhesive. Smooth to avoid wrinkles and overlap seams by at least 2 inches (5 cm).
3. Immediately apply a sizing coat of LAGFAS® Adhesive/Coating at 80 – 90 sq. ft./gal. (2.0 – 2.2 m2 /l). The dry film thickness of this application will vary with the fabric selected. BRUSH Use clean paint brushes. Apply a 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. Lagging cloths and tapes if dipped must be applied to the insulation while lagging adhesive is still wet.

Spray

LAGFAS® Adhesive/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. Corrosion resistant pumps and fittings are suggested.

Clean Up

Use clean fresh water for cleaning equipment before product dries. After product dries, use solvent to clean up, such as chlorinated solvent (non-flammable) or xylol (flammable).
