Why is my silicone sealant coming loose?
When silicone sealant comes loose from the substrate, this is often the result of poor preparation or an incorrect product choice.
Possible causes why silicone sealant comes loose
Poor substrate preparation
- Poor adhesion can be caused by a dirty, damp or greasy substrate. Therefore, thoroughly clean the substrate before applying the silicone.
No primer used
- On some substrates, a primer is required to guarantee optimal adhesion of the silicone sealant.
Incorrect sealant for the substrate
- Not every silicone sealant adheres equally well to every substrate. It is therefore important to choose a sealant that is suitable for the material and the application.
