How to Install Your Vinyl Decal

Installing a vinyl decal is easier than it looks. The key is to work slowly, prepare your surface properly and avoid rushing the process.

For the best results:

  • Install in a clean, shaded and wind-free area.
  • Make sure surface temperature is between 55-80 degrees Fahrenheit.
  • Avoid installing on extremely hot, cold or wet surfaces.
  • Do not install on fresh paint, damaged clear coat, cracked paint or peeling paint.
  • Check that the decal is the correct size and orientation before removing the backing.

Things you will need:

  • Microfiber towel
  • Rubbing alcohol or mild soap and water
  • Plastic squeegee or a firm card
  • Painter's tape or masking tape
  • Scissors
  • Measuring tape
  • Spray bottle for wet installation, if needed
  • One or two drops of plain dish soap, if using the wet method

    Do not use glass cleaner, Rain-X, wax, detailing spray or a cleaner that leaves a coating behind. These products can prevent the vinyl from sticking properly.

Dry installation method

The dry method is recommended for most lettering, detailed graphics and smaller decals.

  1. Clean the surface. Clean the installation area with mild soap and water, and let it dry completely. Wipe the area again with rubbing alcohol and a clean microfiber towel to remove any remaining oil, wax or residue. Allow the the surface to air dry.
  2. Prepare your decal. Place the decal on a flat surface and firmly rub over the entire design with a squeegee or card. This helps the vinyl bond to the transfer tape. Pay attention to small details, thin lines and pointed edges.
  3. Position the decal. Place the decal against the surface without removing the backing paper. Measure it's position and adjust it until everything is centered and straight. Secure the decal in place with a strip of painter's tape through the center. This creates a hinge and prevents the decal from shifting out of position. Step back and confirming positioning before proceeding.
  4. Apply first half. Lift one side of the decal and peel away the backing paper away from the transfer tape. If any parts of the decal remains on the backing paper, lower the transfer tape and rub that area firmly then try lifting again.
  5. Apply the other half. Remove the center hinge tape. Lift the unapplied side, peel away the remaining backing paper and slowly lower the decal while smoothing it from the center outward. Go over the entire design several times with firm pressure, especially around the edges and smaller details.
  6. Remove the transfer tape. Wait a few minutes before removing the transfer tape, especially in cooler weather. Slowly peel the transfer tape back against the surface at a sharp angle. Do not pull it straight outward. If any part of the vinyl lifts with the transfer tape, stop. Lower the tape, press the vinyl firmly into place and peel again more slowly. Once the transfer tape is removed, press down all edges and details with your finger or squeegee.

Wet installation method

The wet method can make it easier to position larger decals and smooth out air bubbles. However, it should not be used for every design. Do not use the wet method on small lettering, highly detailed graphics or decals with thin disconnected pieces unless the product instructions specifically recommend it. Paper transfer tape can also become difficult to remove if it gets oversaturated.

  1. Prepare the application solution. Fill a clean spray bottle with water and add only 1-2 drops of plain dish soap.
  2. Clean the surface. Clean the area with the application solution, dry it then wipe it with rubbing alcohol.
  3. Prepare the decal. Firmly rub over the decal with your squeegee to help the vinyl bond to the transfer tape. Slowly remove the backing paper. If the vinyl remains on the backing, lower the transfer tape, rub the area again and peel more slowly.
  4. Lightly spray the surface. Lightly mist the installation surface with the application solution. The surface should be damp, not dripping wet. Avoid soaking the adhesive or transfer tape.
  5. Position the decal. Place the decal onto the damp surface and gently slide it into position. Once it is aligned, hold the decal steady and begin pressing from the center outward with your squeegee. Use firm, overlapping strokes to push the water and air toward the outside edges. Continue until as much moisture as possible has been removed.
  6. Let the decal set. Allow the decal to sit before removing the transfer tape. If the vinyl lifts when you begin removing the transfer tape, stop and allow it to dry longer.
  7. Remove the transfer tape.

How to remove your vinyl decal

Vinyl decals can be removed, but they cannot be reused. For the safest removal, work slowly and avoid using excessive force.

  1. Warm the decal. Choose a warm day or use a hair dryer on a low setting. Hold the hair dryer several inches away and move it continuously across a small section of the decal. The goal is to gently soften the adhesive, not make the vinyl or surface hot. Use extra caution around tinted glass, plastic panels, painted surfaces and window seals.
  2. Lift an edge. Use your fingernail or a plastic scraper to gently lift one corner. Do not use a metal blade on painted surfaces. Metal blades can also damage window tint, coatings, seals and some types of glass.
  3. Peel slowly. Pull the vinyl back against itself at a low angle rather than pulling it straight away from the surface. Continue warming small sections as needed. Slow removal reduces the chance of leaving adhesive behind or tearing the vinyl into small pieces. If the decal begins tearing, warm a smaller area and continue peeling gradually.
  4. Remove adhesive residue. If adhesive remains, apply a small amount of vehicle-safe adhesive remover or rubbing alcohol to a microfiber towel. Test the product in an inconspicuous area first. Gently wipe the residue until it loosens, then clean and dry the surface. Do not use harsh chemicals, abrasive pads or sharp tools.
