Installation:  

1.  Make sure surface is clean and if placing on glass wipe area that decal will be placed with rubbing alcohol first.  

2.  Remove the backing (usually white but some may have a clear backing) so you will be left with the transfer tape and the decal.  DO NOT stick decal to surface until you are satisfied with the placement.   

3.  Stick top of transfer tape and decal to surface and use the edge of a credit card, small squeegee etc. to rub the decal against the surface as you lay it down (this helps to eliminate air bubbles).  You can rub across the decal several times and in different directions to ensure it all has adhered. 

4. Once decal is completely pressed to the surface lift up a corner of the transfer tape and slowly peel away from surface and decal.  If any of the decal starts to release from the surface (more common on wooden surface ) just lay transfer tape back down and press with card, squeegee again and try to slowly remove transfer tape again.  

For anything that will be allowed to get wet. :DO NOT ALLOW DECALS TO GET WET FOR ATLEAST 24 HOURS AFTER PLACEMENT.
