General Application


What does ORAFOL recommend when performing a wet application with its products?

Wet applications are typically recommended for large surface applications on glass. Wet applications should only be done in ambient temperature environments of at least +60° F. For wet applications, ORAFOL recommends using a medium-tack application tape. After the application fluid has had ample time to dry, remove the application tape carefully at a 180° angle. Newly applied graphics should remain in the application environment for at least 24 hours to promote uniform adhesion characteristics and allow any residual moisture to evaporate. (Recommended ingredients for wet application fluid: one tsp. of traditional Joy® or Dawn® dish detergent to one quart of water. Detergent should not contain moisturizers, lotions, or bleaching agents.) Wet applications are not recommended or warranted when applying material with dispersion water-based adhesive systems, ORACAL® Metallic films, ORALITE®/Reflexite® series films, CommandForm™ or RapidAir® technology. Windex® or other glass and surface cleaners should never be used as an application fluid. Contact ORAFOL Product Technical Support for further information.


How long should I wait before applying ORAFOL materials over One Shot® enamel paints on MDO board?

ORAFOL materials may be applied directly to One Shot® enamel paints when proper outgassing guidelines are followed. One Shot® recommends a (minimum) of four days at 60° F with proper air circulation to allow for proper paint outgassing. Please allow several more days if the ORAFOL film is printed and laminated. Both ORAFOL and One Shotۤ® recommend performing a test application prior to completing the intended job. Please contact ORAFOL Technical Support at techsupport-americas@orafol.com for further testing and outgassing procedures. (Please note that the paint curing process may take up to 30 days)


I hear it may take anywhere from 3-4 weeks for paint to cure on painted MDO board. Do you have any suggestions on bypassing this?

Unfortunately the paint curing process is very important for a successful vinyl application. If this is a substrate that is used on a regular basis, it may be beneficial to keep a few extra painted boards in stock that have had plenty of cure time. The idea is to have these in stock and ready to go for a successful and worry free vinyl application.


Is it ok to apply my ORAFOL vinyl directly to pre-primed MDO boards?

This would not be a good idea. The surfaces to which your ORAFOL vinyl films will be applied must be smooth, non-porous and thoroughly clean from dust, grease, or any contamination. Primer and flat paints are too porous of a coating and would collect dirt and moisture resulting in poor adhesion between the adhesive vinyl and the substrate. A smooth, properly cured, glossy exterior rated enamel coating would be ideal for vinyl application.


Can I apply pressure-sensitive films over latex painted surfaces?

Be very cautious when applying vinyl films to flat finish latex painted surfaces. Heavily tinted latex paints contain surfactants (soap-like chemicals) that leach onto the surface throughout its life, causing adhesive failure. Latex paints also contain plasticizers which can migrate to the adhesives in many pressure sensitive films, also causing failure. For exterior vinyl applications over a painted surface, we recommend the use of oil-based gloss enamel, or acrylic gloss enamel coatings. For interior vinyl applications over latex painted surfaces, we would recommend an eggshell or satin finish. Surfaces which have been recently painted, always allow at least 3 weeks curing time.


Can ORAJET® 1663 adhere to clean concrete?

Series 1663 can only adhere to smooth, sealed concrete surfaces. We do not recommend applying this product to porous concrete, asphalt, tile with wide grout lines, or masonry surfaces.


Can ORACAL® 751 High Performance Cast be applied to flexible substrates such as awnings?

Yes. Depending on the material that the awning is made of, ORACAL® Series 751 is often a good choice due to its conformability and durability. Be sure to watch out for awnings that contain waterproofing compounds or porous or textured surfaces, as these can retard adhesion. Always perform a 24-hour adhesive test on the actual substrate prior to completing the final installation.


What is the best cleaning solution to use for prepping substrates prior to application with ORAFOL films?

IPA (isopropyl alcohol) is generally recommended unless the substrate manufacturer states that there is an incompatability. Caution: many cleaning agents can leave a residue that either prevents vinyl adhesion or attacks the vinyl adhesive, such as Windex® and other glass or surface cleaners, Rapid Prep®, and degreasers.


What should I use if IPA (isopropyl alcohol) has been used to clean glass and there still seems to be a surface residue preventing vinyl adhesion?

We have found that Bon Ami® glass cleaner should remove any chemical residues left behind by other glass cleaners.


Which kind of ORAFOL films are suitable for making decals for automobiles?

ORAFOL offers a wide range of graphic marking films and digital media that are suitable for automotive decals. While you can obtain more specific application recommendations in the product section of our website, as a general rule we recommend the use of films with a solvent-based adhesive for automotive use. The solvent adhesive will last much longer when exposed to changing surface temperatures, chemicals and mild solvents. Also, our cast films tend to be more conformable and durable for demanding longer-term applications.
