3M™ Polyurethane Protective Tape

Painting Instructions

Introduction

3M™ Polyurethane Protective Tapes and Boots may be painted after application to achieve special color effects or

to color match application surfaces. Prior to painting, the 3M Tapes and Boots must be properly applied to a clean,
smooth surface.

A. Painting Methods - Standard spray-painting methods are recommended.

B. Preparation of the 3M Tape or Boot Surface for Painting - Light scuffing and/or solvent wiping the film surface
prior to painting is recommended. The following procedure should be followed. 1. Scuff the 3M Tape or Boot surface
with 3M™ Scotch-Brite™ General Purpose Pad 7447. 2. Saturate a clean, lint-free cloth with acetone or isopropyl
alcohol* and lightly wipe the 3M Tape surface. 3. Wipe surface dry with a lint-free cloth before the solvent
evaporates from the surface.

C. Painting the Applied 3M Tape or Boot - Most high-quality outdoor grade enamels, lacquers and polyurethane
paints can be used. 1. When using single-part paint systems, you may paint directly over the applied 3M Tape or
Boot without using the recommended primer system. Thin coatings are best for maximum resiliency-. 2. When using
two-part paint systems, such as Military Spec two-part urethane paints, it is critical that the surface of the 3M Tape
or Boot be primed with a polyamide cured, two-part epoxy primer such as those meeting MIL-P-23377.

D. Drying - The painted tape or boot may be air dried at room temperature or higher temperatures to shorten drying
time. Oven drying at temperatures above 150°F (66°C) is not recommended.

*Note: When using solvents and other chemical products, extinguish all ignition sources, including pilot lights, and
follow the manufacturer’s precautions and directions for use. Consult local air quality regulations that may regulate
or prohibit the use of surface preparation and cleaning materials based on solvent (VOC) content.

This image is sort of out of context – are there any images of a painted PPT boot/film that could be used here? Or a
photo of a painting operation that is more general?
