Another great Vinyl Lettering and Vinyl Striping job by one of our customers. He did this himself. Spring will be here soon enough. This is a great time to add Vinyl Lettering and Vinyl Striping to your boat once the surface has been properly cleaned and prepped.

Regardless of the surface, or whether you perform a wet or dry application, if you do not properly clean the surface before installing the Vinyl Lettering the performance of the adhesive will be compromised. Also, wetting solutions can bring on additional problems on dirty surfaces because the liquid will relax the dirt and debris and make the Vinyl Lettering harder to install.

You might think that prepping the surface is the easiest part of the process and impossible to forget, but most of the time it is the easiest steps that are overlooked. If you are relying on someone else to install your Vinyl Lettering, make sure that the installer is not in a rush and understands the process. A properly cleaned and prepped surface will ensure that your Vinyl Lettering stays in tiptop shape.

Surface preparation for vinyl lettering and full color printed decals.

It is critical to prepare a surface no matter what it is- metal, wood, plastic, glass, aluminum, painted substrates, etc-if you are using self-adhesive vinyl lettering, you will need to prep the surface. Don’t ever assume a surface is clean; even freshly painted surfaces need prep. When there is a new car or truck right out of the showroom you would assume it was clean… but NO there is probably wax and/or rain-x, a product to help shed water from glass (widely used on glass on all vehicles) and metal that will need to be removed.

Vinyl letters and graphics will adhere to most painted wood, painted metal, glass, fiberglass and plastic surfaces. The surface must be smooth. Painted surfaces must be completely cured before applying vinyl. Surfaces painted with oil based enamels work best. Latex can work, however we don’t recommend it. Some latex paints simply do not work; letters will fall off just days after installation. If you do use latex paint, use a semi gloss or egg shell for interior installations for best results. For the best application on a painted surface use enamel based paint. Vinyl letters will not adhere to rough surfaces such as raw wood, chipped/peeling paint, cloth, rubber, or canvas.

Preparing Surfaces for vinyl letter installation.

1. Always assume surface is dirty.
2. Clean surface with mild detergent using paper or cloth towels , 409, Windex or something similar.
3. For the final cleaning, use denatured alcohol or equivalent, it will completely clean the surface and evaporate rapidly, leaving a perfect surface for vinyl letter installation and decals.

Freshly painted surfaces need time to cure completely before applying self-adhesive vinyl. Enamel based paint should cure for 7 days so that it is completely dry; applying too soon can cause the letters to become unstuck and fall off. ( the curing process)

Note: Denatured alcohol will remove wax.

WHAT YOU NEED: Paper towels, razor knife, scissors, squeegee (supplied with all orders), denatured alcohol, squirt bottle, detergent soap, and of course vinyl striping supplied by www.vinylstriping.com.


To begin we need to clean the application surface with denatured alcohol. This is the best way to remove any oil residue and wax, leaving a completely clean surface for vinyl application.

1. Saturate the surface with a soapy water solution (99.8% water and a couple of drops of detergent soap), and shake it up (to add a bit of slipperiness to the water).


2. Pull a foot or two of the vinyl striping away from the liner. Apply vinyl gently (get as straight and level as possible here).


3.  Now saturate the front of the vinyl (if applying to drywall or similar surfaces apply dry) to help with squeegeeing down onto surface (it will prevent scratching and help with application).


4. Start to squeegee the vinyl striping down; the water will squish out and the vinyl will adhere.


5. At this point work your way down the vehicle a few feet or longer at a time and repeat steps 1, 2, 3, and 4.


Perforated window signs have opened up a new world of promotional opportunities by turning glass doors and windows into prime advertising space. Perforated window signs are applied to the outside of your window. They work well for vehicles and store fronts. We sell this material for $5 a square foot on our website Perforatedwindowsigns.com. Perforated vinyl material looks great from the outside but is also almost invisible from the inside. Perforations in the material provide a clear view outward while maintaining the illusion of a full color graphic from the outside. This is a great alternative to hanging signs, vinyl decals, and static window signs when you do not want to obstruct anyone’s view from the inside of your business facing out, truly a unique and inexpensive way to promote your products and business.
