Frequently Asked Questions

Does this neutral silicone sealant require a primer before application?

No primer is required. This is a one-component, neutral curing sealant that bonds well to most common building materials — including glass, aluminum, PVC, and stone — without any primer, making the application process faster and more convenient.

Is this sealant safe to use on stone surfaces?

This sealant is suitable for joint bonding and waterproof sealing on stone surfaces. However, please note that pollution-free results on stone cannot be guaranteed, as some porous stones may absorb pigments or oils. It is recommended to test on a small area first.

What is the weather and UV resistance performance of this sealant?

After curing, the sealant exhibits excellent weather resistance, including strong UV resistance, ozone resistance, aging resistance, and the ability to withstand both high and low temperature extremes — making it ideal for outdoor building applications and long-term exposure environments.

What are the main application areas for this neutral silicone sealant?

This sealant is widely used for joint bonding and waterproof sealing between glass, stone, sun rooms, and plastic steel materials. It is also suitable for the installation and sealing of building doors, windows, and door/window glass assemblies.

Is this sealant compatible with other silicone products?

Yes. This neutral silicone weatherproof sealant has good compatibility with other neutral silicone products, ensuring reliable performance when used alongside standard materials in multi-material construction projects.

Is this sealant corrosive to metals or sensitive materials?

No. As a neutral curing silicone sealant, it does not release acetic acid or other corrosive by-products during curing. This makes it safe for use on metals, mirrors, and other corrosion-sensitive surfaces commonly found in construction and glazing applications.
