Silicone adhesive is used to create height on your crafting projects and so makes this adhesive perfect for 3D Decoupage and is even called by some the 3D Decoupage glue.
Silicone allows you to chose the depth or height required so you are in control of the overall finish of your project as opposed to using foam pads in which you are restricted to the variety you have. Silicon is also perfect for your floral arrangements on your crafting projects as you can build up the required height meaning you do not have an overall flat effect.
Silicone does take a little time to dry so requires a bit more patience, however,I personally believe it is well worth it!
Silicone can be used on metal, glass, ceramic, wood, plastics and card.
