GENERAL PROCEDURE In brief, the repair consists of (a) cleaning the area. to be repaired, (b) applying adhesive to patch and to the work, (c) allowing adhesive onboth to dry about an hour, an
29、d (d) pressing patch in place. 3. DETAILED PROCEDURE a. PREPARE PATCHES (1) Cut a piece of the patching fabric from the kit. (2) Make it large enough to provide all the patches that will be needed that day. (3) Clean the lighter coated side (duller and less smooth) by wiping with paper towels wet (b
30、ut not dripping) with toluene solvent. Allow to dry. .- (4) Stir the adhesive and apply to the cleaned side of the piece, Spread rapidly with a minimum of strokes. Overlap strokes as little as possible, (When a large piece of fabric is being coated a paint brush may be used or two or three kit brush
31、es may be taped together). 5 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-M-43946A (5) Dry until the piece can be cut into patches without the adhesive fouling the shears. This may take an hour, but might be as little as 20 minutes on warm dry
32、 days. .d (6) Cut patches in the required sizes and shapes as needed (generally rectangular). Round off corners. The patch should cover the damage and extend into the surrounding area of the garment about 3/4 inch in all directions. (7) These adhesive-coated patches may then be applied in the subseq
