Firstly you need to understand thatsilicone does not stickto anything other than the adhesive system or the PSA (pressure sensitive adhesive). This means silicone does not interface directly with wood or metal or any other material,instead it interfaces with the PSA itself. The diagram below explains this. PSA

Does silicone stick to anything?
Once cured, silicone can be extremely difficult to stick to surfaces. Silicone rubber will almost always need some form of adhesive to enable them to fix to a surface and in many ways can be related to Teflon by the way it repels things sticking to it, hence the reason Teflon is use for frying pan coatings.
Where should silicone not be installed on wood?
There are two main places it never should be installed, wood or any painted surface. If paint will ever be applied to an area, then silicone does not belong there, ever, in any way.
How to use silicone glue on wood?
Silicone glue comes in different sized tubes and can be applied directly to the wood. Bigger sized tubes fit perfectly in caulk guns to better facilitate the process, especially if you are working on a large area. To apply the adhesive, get hold of the tube, or gun and tube, and start adding it around the edges.
Why can鈥檛 you glue silicone?
Due to the low surface energy of cured silicones, it is almost impossible to get anything to easily stick to silicone. Because of this special glues and surface preparations are needed to bond cured silicones to another material. What glues work with silicone?
