How to Install Aircraft Vinyl Decals:

The lettering/graphic may not adhear very well if it is cold and damp. The surface temperature should be at least 15 degrees C (60 degrees F) to install vinyl lettering or graphics. If you have a hot air gun then you can blow some air over the surface to warm it.

The example below is for installing aircraft registration letters, but similar method can be used for any graphic using appplication cover tape.
Please read the instructions all the way through, to ensure you understand the complete process before proceeding with installing decals.

Step 1:VERY IMPORTANT to Clean the surface well before applying the graphic. Remove dirt, oil, grease, wax and anything that will prevent the glue from adhering to the surface.

We use diiferent cleaners depending on surface, Isophophyl Alcohol is very good as can be acetone (nail varnish remover). On painted surfaces use a mild detergentent or panel wipe works well. Let it dry and wipe with a clean cloth.

When dry without removing the backing or the top masking from the decal, affix it to temporarily to the surface with masking tape roughly where you want it to be.

Step 2: Make sure the decal is lined up exactly where you want it.

There should be a streight cut line on the bottom/Top of the Graphic if not better to do that first so you have a datum to work from.
Line the graphic up with a line on the aircraft or set it level to the eye. Use a tape measure to check centres etc. Step back and check that it looks Okay.

Step 3: Put a strip of masking tape down the center of the graphic roughly dividing it in two. On small graphics, 6 inches and under, you can put this line of masking tape down just one edge.

This tape will hold the graphic in place for the next step when you lift one side to remove the backing.

Step 4: Lift half of the graphic and peel of the backing right up to the masking tape you put down the middle.
You can add a bit of tape on it to hold it back out of the way for the next step.
Step 5: Tear off this half of the backing with your fingers (no scissors required) and discard it.
Step 6: Start to lay the graphic back down on the surface. Starting from the centre and working your way out to the end so you push any air with you. Use a Squeegie (credit card) to work the graphic down onto the surface and work out any bubbles. Persistent bubbles can be poked with a pin to let out the air.
Step 7: Remove your strip of masking tape and fold back the other side to peel off the backing and work down like first half. Make sure it is well wiped down.
Step 8: Then peel of the top masking material, pulling it at 45deg and keep your hand close to the surface. Wipe the letters down with a soft Squeegie or glove.
If any bubbles they can be pricked with a pin and wiped down.
On shiney fabrics like ultralam, mylar etc as found on microlights, like Xair Hawk, C42, Skyranger etc, you may find that blowing hot air over the letter and rubbing in with your fingers (in a glove or cloth) will make the graphic adhear better to the surface especially on underside of wings.

To remove vinyl decals, first heat them up with a hair dryer to soften the glue. This will help release the glue and prevent damage to the painted surface below. This is especially important when removing vinyl graphic's from painted fabric covered aircraft!
