Primers, adhesives and related articles
For bonding materials, it is best to work wet in wet. If that is not possible, a primer (wet on dry) or an adhesive (dry on dry) is often necessary.

3 Methods to bond
Wet in wet: If two similar products such as silicones or epoxies, polyurethane, etc. have to bond well with each other, it is of course best to work wet in wet. That means the second coat is applied while the first is still runny or at the very least very tacky.
This is used in addition silicone to build up thick layers when silicone is spattered or sprayed instead of poured. With epoxy and PU, it is often done correctly to avoid having to pour a very thick layer or large volume in one go. The resin could then become too hot and shrink considerably, tear, discolour or even burn.
The disadvantage of this technique is that you have to wait until you can continue and that you can often (in the case of clear resins) see a dividing line between the two layers.
Wet on dry: If you want to have a resin or silicone material that has yet to be cured adhere to a cured material, we call this wet on dry bonding. This is no problem for condensation silicone. Condensation silicones always adhere to cured condensation and to addition silicones. Epoxy also works well. It is more difficult with PU and with acrylic resin.
In all cases, it is wise to roughen the surface and degrease it well with isopropanol!
It is often wise to use a primer. For example, when gluing silicone to iron using the G790 primer or PU on a stone substrate with the primer Nevirprim.
Dry on dry: If you want to bond two cured products, you can use a flexible bonding material or a stiff glue.
Silicone caulk is a good way to make silicone bond to silicone. For example the E4, E41 and E43. Silicone sealant is flexible and therefore provides a flexible bending and stretching bond.
You can often also use an ordinary condensation silicone for good adhesion.
The sealant can also be used to bond silicone to a wooden or iron surface (with or without some extra help from a primer).
Silicone sealant can also be used to flexibly bond iron to iron or wood to wood etc.
The flexpox (a flexible epoxy) can also be used to connect materials flexibly.
In addition to flexible sutures, you can also use good cyanoacrylates. These often have to be combined with a primer on silicone and other rubbers to allow the adhesive to bond. This application is very fast and strong. The disadvantage is that it does not give much and the silicone / rubber often hardens at the place of application.
