Prepare the Surface:
Wipe down the surface with a microfiber cloth with either rubbing alcohol or water and let it dry completely.

Position the Sticker/Decal:
Carefully peel away the backing paper from the vinyl decal/sticker, exposing the adhesive side. Position the decal on the surface where you want it, using a ruler or tape to ensure it's straight.

Apply the Sticker/Decal:
Use a squeegee or a credit card to gently press the decal/sticker onto the surface, starting from the center and working outwards to remove any air bubbles.

Remove the Transfer Tape
(For Transfer Decals)
Slowly peel away the transfer tape, making sure the decal remains adhered to the surface. If any parts start to lift, press them back down and continue removing the tape.

Final Touches:
Smooth out any remaining bubbles by rubbing them with the squeegee or your fingers.
