FAQ - Frequently Asked Questions

1. What is the purpose of a primer for silicone sealant?
   A primer helps to increase the adhesion of silicone sealant on surfaces where natural adhesion is insufficient, particularly smooth and non-porous surfaces.
2. Is it mandatory to use a primary primer?
   No, but it is strongly recommended on non-porous substrates or in areas subject to humidity, vibration or mechanical stress, in order to ensure optimal durability of the joint.
3. Can I use it on natural stone or concrete?
   No, this product is only intended for non-porous surfaces. For natural stone or concrete, a specific primer for porous surfaces is required.
4. Which silicones is it compatible with?
   It is compatible with the majority of DL Chemicals silicone sealants and, in general, with most neutral or acetic silicones on the market (preliminary testing is recommended).
5. How long should you wait before applying silicone?
   Drying time is usually short (a few minutes), but it is imperative to follow the manufacturer's recommendations indicated on the packaging or technical data sheet.
