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. how long should silicone dry before adding water? I would wait at least 3 days before adding water. IF you add water sooner, then chemicals in the silicone may leach out and stay in the water even if you don’t plan to put fish in for a few weeks. Also, the silicone may become weak with water contact. Subsequently, one may also ask, will silicone stick to wet surface? Before applying silicone sealant, you should make sure that the surface you plan to apply it to is free of dirt, dust, and other particles that can lead to a weaker seal. Leaving the surface wet can cause problems, because silicone sealant is waterproof. Be sure you remove all water completely.What will Silicone not stick to?Generally, silicone RTV mold making rubber does not stick to anything, and nothing will stick to it.
