Frequently Asked Questions:
Discover fun facts about construction sealants - waiting for you to uncover in our pages! :-D
(1) Why Moisture Matters for Silicone Sealants?
Silicone sealants cure through a reaction with moisture in the air. That's why proper ventilation and humidity levels are important during application-too dry, and the curing process slows down; too humid, and it might not adhere proprly!
(2) Materials That Silicone Sealant Won't Stick To
Silicone sealant generally provides excellent adhesion to most construction and industrial materials. However, it does not adhere well to certain surfaces, such as those containing oil, plasticizers, or specific metals like copper, lead, and galvanized steel. To ensure optimal adhesion, it's essential to clean surfaces thoroughly and remove any contaminants that may interfere with the bond before applying silicone sealant.
