b. lnsulation/Removal
NOTE
Prior to removal of old insulation, cut the new replacement material to size using the old
item as a sample.
(1) Remove as much old insulation material as possible, by pulling or scraping it away from the metal
surface.
Acetone and methyl-ethyl ketone (MEK) are flammable, and their vapors can be explosive.
Repeated or prolonged skin contact or inhalation of vapors can be toxic. Use a well-
ventilated area, wear gloves, and keep away from sparks or flame.
(2) Soften and remove old adhesive and insulation residue, using acetone or methyl-ethyl ketone (MEK)
and a stiff brush.
c. Installation
(1) (Cut to size.
(2) Be sure that the surface to which the insulation is to be applied is clean and free of paint and old
adhesive material.
(3) Coat the mating surfaces of the metal and the insulation with adhesive (item 2, Appendix E). Let both
surfaces air dry until the adhesive is tacky, but will not stick to the fingers.
(4) Starting with an end, carefully attach the insulation to the metal. Press into firm contact all over.
