Preparing the Surface
The high-quality special adhesives used on ORACAL self-adhesive materials create an excellent bond with just about any clean, smooth, weather-resistant surface that is free of grease, wax, and silicone.

For a long-lasting bond, the target surfaces must be properly prepared. Before mounting the material, clean the surface with isopropyl alcohol and wipe it dry with a clean cloth.

Gas bubbles may form between the film and the surface if any solvent residue remains as a result of improper cleaning or if the paint on the surface is too fresh. Allow at least three weeks to pass before adhering the film to paint that has been oven-dried and/or baked.

ORACAL pressure-sensitive products should never be applied to surfaces painted with latex paint.

NOTE: Isopropyl alcohol is recommended as the cleaning agent as other agents may, under certain conditions, attack the paint or reduce the adhesive strength of the film.

Application Temperatures
ORACAL self-adhesive materials should never be adhered at temperatures below 46°F if it has a solvent polyacrylate adhesive or below 50°F if it has a polyacrylate dispersion adhesive.

Avoid any significant drop in temperature during the first 24 hours after application. Should this occur anyway, we recommend treating the film with hot air from a heat gun or other heat source.

Adhesion
There are two major methods of adhesion: dry and wet application. Wet adhesion is only recommended for PVC films.

For dry applications, first place the cut film on the surface to which it is to be adhered and press it down firmly to the surface at one corner. Apply the remainder by bringing a plastic squeegee across the film in overlapping sweeps. For top coated PVC films, only use felt squeegees!

Wet application should only be done when temperatures are at least 64°F. Spray the exposed adhesive side with low-surface-tension water (water mixed with a flushing agent, don’t use concentrated agents) and place it upon the application surface.

Position the cut film where you want it. The wet application method allows for more precise positioning of film. Press the film to the surface using sweeping, overlapping motions with a squeegee. Be certain that there is no water between the surface and adhesive to avoid bubbles and ensure a positive bond.

The bond is improved if the film is pressed again after a few hours. If the wet method is used on materials with dispersion water-based adhesive, the adhesive turns white—a process that is reversed after some time. The time it takes the adhesive to become clear again depends on the surrounding conditions, such as temperature and humidity.
