7. Painting the Repair:
A. An important factor in obtaining a quality paint finish is the proper preparation of the repair and
surrounding area before applying any paint.
B. It is recommended that parts be cleaned prior to painting with a commercial cleaner or a solution
made from one-fourth cup of detergent mixed with one gallon of water.
C. The paint used for coating thermoplastic can be either lacquers or enamels depending on which is
preferred by the repair facility or customer. (See NOTE.)
It is extremely important that solvent formulations be considered
when selecting a paint, because not all lacquers or enamels can
be used satisfactorily on thermoplastics. Some solvents used in
the paints can significantly affect and degrade the plastic
properties.
D. Another important matter to consider is that hard, brittle coatings that are usually best for abrasion
resistance should not be used in areas which incur high stress, flexing or impact. Such coating may
crack, thus creating a weak area.

SURFACE PREPARATION.
1. Clean all surfaces with a suitable cleaning solvent to remove dirt, grease and oils. Solvents may be
applied by dipping, spraying or mopping.
2. Insure that no moisture remains on the surface by wiping with a clean dry cloth.
3. Outline the area to which the liquid safety walk compound is to be applied, and mask adjacent
surfaces.
Newly painted surfaces, shall be allowed to dry for 2.5 hours
minimum prior to the application of the safety walk.
