(a) Dry the surface with a clean cloth. Do not let air dry.
E. Prepare the Decal for Installation
S 804-010
(1)
On decals with an area less than one square foot, remove the backing and put the decal face down on a smooth surface.
S 424-011
(2)
On decals with an area more than one square foot, use masking tape to put the decal on the receiving surface.
(a)
Cut a sheet of carrier tape approximately four inches longer than the decal and approximately the same width. When you use premasked decals, you can use the premask as a carrier.
(b)
Put the carrier over the decal, with the edge you will hang two to three inches beyond the decal edge.
(c)
Hang the carrier on the receiving surface with masking tape.
(d)
Rub the carrier on with a plastic scraper. Use short strokes and work from the middle of the joint to the edges. Be sure to remove all wrinkles and air bubbles.
(e)
Fold the carrier and decal back at the joint, along the surface with the backing up. Use masking tape to hold in this position.
(f)
Remove the decal backing.

(3) On strip decals, remove about one foot of backing and put the decal face down on a smooth surface.
S 804-013
WARNING: USE A-2 AND A-3 ACTIVATORS AND CYCLOHEXANONE IN WELL-VENTILATED
_______ AREAS AND DO NOT BREATHE THE FUMES FOR A LONG TIME. A-2 AND A-3 ACTIVATORS AND CYCLOHEXANONE ARE TOXIC AND FLAMMABLE.
(4) Apply activator or cyclohexanone to the adhesive surface of solvent-activated decals. If ambient temperature is less than 60°F, use A-3 activator.
(a)
Put a felt squeegee into the activator solvent momentarily. Remove unwanted solvent with an absorbent cloth.
(b)
Move the felt squeegee evenly across the adhesive side of the decal. Do not let the activator touch the film face. 1) Apply activator to strip decals for approximately six
inches. 2) Apply activator to the full surface of all other decals with strokes that overlap.
F. Procedure
S 424-014
(1) To apply decal to a regular surface, do these steps:
(a)
Put the decals with areas less than one square foot in position and bond one edge to the surface. Hold the remainder of decal taut and a small distance from the receiving surface with a piece of backing on the adhesive side.
(b)
For decals with an area greater than one square foot, move the carrier into position. Hold the free end taut and a small distance from the receiving surface with a piece of backing on the adhesive.
(c)
Align and bond approximately three inches of strip decals to the receiving surface. 1) Use the applied section as a joint and strip up to three
feet of the backing. If necessary, apply activator to the adhesive. 2) Align the stripping and hold it taut and a small distance away from the receiving surface.
(d)
Start at the joint and rub the decal on the surface with the plastic scraper with short fan-like strokes. Do not let the adhesive touch the receiving surface until the plastic scraper pushes it down.
(e)
Continue to strip, apply activator, and apply strip decals until you apply all of the decal.
(f)
When you apply strip decals around a corner and a splice occurs, overlap decal a minimum of two inches.
