Vinyl letters will not adhere to rough surfaces such as raw wood, chipped/peeling paint, cloth, rubber or unpainted metal.

The surface temperature must be at least 55 °F. for vinyl to adhere properly.

All surfaces must be considered dirty and cleaned prior to applying vinyl letters. Use soap and water to clean most surfaces. Any waxes should be removed with a combination of isopropyl alcohol and water. The surface temperature must be at least 60 °F. to insure proper installation.

VEHICLES AND BOATS:
Vinyl letters will not adhere to vehicles or boats that have been waxed. Vinyl letters will not stick to some tinted windows. Do not apply vinyl letters to the back of vehicles that have wiper blades. The wiper blades will scratch the letters.

CARE OF VINYL LETTERS:
Wash gently with soap and water. Never Power Wash. It will chip and/or remove the letters. Do not get gasoline, solvents or oil on the letters. It will destroy them.

1. Begin by purchasing MDO (Medium Density Overlaid) Plywood. Regular plywood will not hold up outdoors. You may have to special order this from a lumber yard.
   
   
2. Using a hand router, remove the sharp edges. The primer will adhere better to a smooth rounded edge.
   
   
3. Prime the panel - we recommend purchasing a good primer. Follow their instructions on priming. Also follow manufacturer's recommendations on which type of paint to use as a finish coat.
   
   We recommend two coats of primer. Sand your sign panel between coats and remove any dust before painting.
   
   
4. We recommend two coats of finish paint, sanding and removing dust between coats. Do not use a flat paint for your finish paint. Vinyl does not adhere well to flat paints.
   
   
5. Paint must be COMPLETELY cured before installing your vinyl letters.
