Wall decals should be applied to smooth, hard wall surfaces. Egg shell, glossy or textured paint surfaces may not allow the decal to adhere as well. Wall decals are removable, but are not generally re-positionable.
Determine where you would like to place wall decals by measuring and marking the installation area. If drywall needs cleaning, use a mild soap with water and allow it to dry.
There are three layers to the decals: The transfer tape, the paper backing, and the actual decal itself (in the middle). Transfer tape resembles see-through masking tape (clear or white). The paper backing is thicker and may have the manufacturer's name on the back of it.
Peel the paper backing from the transfer tape being careful not to rip the vinyl decal. Make sure the decal is still sticking to the transfer tape – if not, lay it back down on the paper backing and rub the decal in that spot until it does. When the paper backing is removed it will leave the sticky side of the transfer tape exposed with the decal attached.
Hold the transfer tape taut and place the decal with the sticky side of the transfer tape against the wall and situate the decal. Using a credit card, remove air bubbles by working the surface from the middle out.
After removing air bubbles and smoothing out the decal you can peel off transfer tape. Work slowly starting at a corner and be careful not to pull up the decal. If a decal edge starts to come up, lay it back on the wall and rub it with a credit card or your fingers until it adheres. Once the transfer tape is removed you can still smooth out any leftover air bubbles using your fingers.
