Decal Application Tips
There are four ways to install vinyl…wet, dry, using a hinge, or you can use The Force and Jedi it. There are advantages and disadvantages to each, and we’ll cover these as well as we can, starting with the benefits and drawbacks of each, followed by detailed instructions.
BEFORE YOU BEGIN!
- Surface must be cleaned with a non-ammonia-based cleaner. Windshield washer fluid works wonderfully, just remember to check the ingredients for ammonia. Use a lint-free cloth to clean the surface and make sure it’s dry before you being applying your decal.
- Temperature must be above 55° Fahrenheit.
- If you choose to use the wet method, mix about 25% windshield washer fluid (or Ammonia Free Windex) to 75% water in a spray bottle.
- Read the instructions fully and gather the tools you may need (ruler or tape measure, painter’s tape, windshield washer fluid and spray bottle, squeegee – a driver’s license will work)
- If there are pencil lines on your decal, they include a vertical center-line and a horizontal base-line for you to use to ensure that your decal is straight.
The Dry Method
Benefits:
- No waiting for fluid to evaporate for transfer tape removal.
- No risk of the decal accidentally moving while removing transfer tape.
Drawbacks:
- It’s a one-shot deal…mess up the decal, you’ll need to purchase another one.
- Bubbles are more likely, but they can be popped with a needle and the air forced out the tiny hole using pressure with your fingertip…using a hair dryer to gently warm the vinyl may help.
This is exactly what it sounds like – you aren’t using any fluid and are applying the decal “dry”. The key to this method is to make sure when you “touch” the decal to the surface, you’ve got it stretched out as much as possible to avoid wrinkles and bubbles…once it touches the surface with enough pressure, there’s no going back. If you’re in the process of touching the vinyl to the surface for the first time, and just a tiny spot hits the surface very lightly, you should still be able to lift the decal and reposition it.
- Follow the steps above to prep your surface.
- Lay the decal on a flat surface face-down and gently peel off the paper backer (the decal should stick to the translucent application tape).
- Line the decal up where you want it to go and gently apply it to the surface.
- Working from the center in an outwards direction, smooth the decal down gently with your hands.
- Use your squeegee and work from the center out to smooth out your decal using slight pressure – but not enough to tear the decal.
- Once you’ve sufficiently squeegeed your decal, slowly peel the application tape off. If your decal starts to lift off during this process, lay it back down and squeegee some more.
- Use a needle to pop any bubbles, and use your fingers to work any air out through the holes (keep the holes as tiny as possible).
The Wet Method
Benefits:
- Decal can be moved around until you are pleased with positioning.
- Less likely to need to use a pin and/or heat to help remove bubbles.
- Fluid may be used to loosen transfer tape before removal.
Drawbacks:
- Must wait for enough fluid to evaporate to remove transfer tape or the decal won’t stick.
- Decal may accidentally move during transfer tape removal.
- Not for use on surfaces with non-latex, water-based paint (wall paint is almost always latex).
- We don’t recommend using the wet method for decals applied on glass.
This is where you’ll use a 25% windshield washer fluid to 75% water mix in a spray bottle. DON’T FORGET – MAKE SURE THERE’S NO AMMONIA! The key to wet application is not to use too much fluid. A good approach is to hold the spray bottle far away from the decal, and using a fine mist, give it a couple of sprays, then use your hands to gently swish the fluid all over the decal and the entirety of the transfer tape.
Once you’ve lightly wet the decal, it’s ready to apply to the surface. Since it’s wet, you’ll have a few minutes to make sure the positioning is correct. You can add a smidge more fluid if it’s evaporating too quickly. Smooth the decal onto the surface using your palms, then working from the center of the decal in an outward direction with your squeegee. You need to squeegee using firm pressure (but not enough to tear the decal!) to ensure that it adheres to the surface properly. You are free to try to remove the transfer tape right away, but you’re better off waiting a little while for the fluid to evaporate. You can check progress by trying to gently pull up a corner of the transfer tape – if the decal sticks, you are safe to proceed. If the decal still pulls up, either wait longer, or you can use a hair dryer to speed up the evaporation process. Spraying the transfer tape and swooshing around the fluid on it will help the transfer tape release more easily (it will wrinkle when it’s wet enough).
- Follow the steps above to prep your surface.
- Lay the decal on a flat surface face-down and gently peel off the paper backer (the decal should stick to the translucent application tape).
- Lightly spray the sticky side of your decal with your windshield washer fluid/water mix and swoosh the fluid around with your hands so it covers all of your decal and the transfer tape.
- Line the decal up where you want it to go and gently apply it to the surface. Reposition if necessary.
- Working from the center in an outwards direction, smooth the decal down gently with your hands – be careful you don’t accidentally reposition your decal.
- Use your squeegee and work from the center out to smooth out your decal using slight pressure – but not enough to tear the decal. The wet method will require more squeegeeing to ensure there’s no fluid left under your decal. Best practice is to give your decal some time for the fluid to evaporate before proceeding to the next step.
- Once you’ve sufficiently squeegeed your decal, slowly peel the application tape off. If your decal starts to lift off during this process, lay it back down and squeegee some more. Using a hairdryer will help any fluid evaporate more quickly.
- Use a needle to pop any bubbles, and use your fingers to work any air out through the holes (keep the holes as tiny as possible).
Using a Hinge
Benefits:
- By far the best way to ensure accurate positioning.
- Less likely to make a mistake with the decal – especially for long, narrow decals or large decals.
Drawbacks:
- Generally requires the most set-up time.
- Measure for your decal’s placement using the base and center lines provided (or the outer edges of the decal). Tape your decal in place in place using a couple of pieces of blue painter’s tape on each side. Now place a strip of tape along the top edge of the decal, with half the width of the tape on the decal and the other half only on the surface – this is your “hinge”.
- Fold your decal up along the hinge and peel the backer-paper off. The tape hinge should be the only thing with a fold in it.
- Wet your decal using the method described above, or lay it down dry – VERY CAREFULLY lay down your decal and smooth it from top to bottom. Begin to squeegee from the hinge down until the entire decal is flat.
- Once your decal is squeegeed flat, squeegee it again from the center outwards to get rid of any bubbles. The adhesive is pressure sensitive, so the harder you can squeegee without ripping the application tape, the better.
- Carefully peel off the painter’s tape hinge and transfer tape.
- Pop any bubbles remaining with a needle. Using your fingers, work any air out through the pinholes – keep the holes as small as possible.
The Jedi Method
Benefits:
- FAST, FAST, FAST.
- Sometimes, due to the nature of design, something that is perfectly centered and straight may not look quite right – especially if the wall or other surface isn’t perfectly square. In this case, “Jedi-ing it” or “using the force” and just eyeing up the positioning may be your best bet.
- You can do this wet or dry.
Drawbacks:
- Best to reserve this technique for when you’re also using the wet method of installation, so you can reposition if necessary.
- It can take practice to master this technique.
- Once your surface is clean and dry, lay your decal face-down on a flat surface and peel the backer-paper off.
- Wet your fingertips with a smidge of windshield washer fluid and spread it around the sticky area of the decal and application tape (be careful not to use too much).
- Turn over your decal and “eyeball” where you’d like it to be. Place the decal on the surface. You should be able to maneuver it a little bit since the back has fluid on it, but you have to be quick.
- Once your decal is in place, use a credit card or similar object to squeegee the surface from the center out to the edges to eliminate any excess fluid and bubbles.
- Use windshield washer fluid to wet the front of the application tape – it will gradually loosen the tape’s hold and make removing it much easier. If your decal starts to peel instead of sticking, squeegee again and apply more fluid to the application tape. The longer you wait, the less the tape will stick and the better adhesion your decal will have as any remaining fluid evaporates.
- After removing the tape, check for any bubbles. These can be popped with a needle and you can work the air out through the tiny hole.
