How to Use


Carefully clean up with a wet mop or HEPA vacuum.


Apply Fiberset PM with airless spray equipment. Use the settings below when applying Fiberset PM:  Spray Settings: Pressure: 1700-3000 P.S.I. Tips: .015-.021


Stir Fiberset PM thoroughly to achieve a uniform consistency. Fiberset PM is premixed; water-addition is not necessary.  Minimum application temperature: 45°F. LOCKDOWN: Sealing microscopic residual fibers after asbestos removal is mandatory on every project. Prior to post-removal air monitoring, apply one coat to all exposed surfaces. Fiberset PM has been accepted as part of a UL Classified Fireproofing System for use with Retro-Guard® manufactured by W.R. Grace & Co., Conn. Coverage should not be less than 500 sq. ft. per gallon on smooth surfaces.


Misting the contaminated air is an effective technique prior to post-removal air monitoring. To pull down free-floating asbestos fibers effectively, stand in the center of the room and hold the spray gun as close to the ceiling as possible. A mist should be sprayed parallel to the ceiling in every direction or in a circle. Apply one coat to the polyethylene sheeting on the walls and floor prior to dismantling containment.


Lockdown: Not less than 500 sq. ft. per gallon.
