Frequently Asked Questions
Does this neutral silicone sealant require a primer before application?
No primer is required. This sealant is a one-component, neutral curing formula that bonds effectively to most common building materials — including glass, metal, stone, and plastic steel — directly without any additional priming step.
Is this sealant safe to use on natural stone surfaces?
This sealant can be used for joint bonding and waterproof sealing on stone surfaces. However, please note that pollution-free performance on natural stone is not guaranteed, as some porous stones may absorb the sealant and cause staining. A compatibility test is recommended before full application.
How does this sealant perform under extreme weather conditions?
After curing, this neutral silicone sealant demonstrates excellent weather resistance. It is highly resistant to UV radiation, ozone exposure, aging, and both high and low temperature extremes, making it well-suited for long-term outdoor building applications.
Can this sealant be used alongside other silicone products?
Yes. This sealant has been formulated for good compatibility with other neutral silicone products, allowing it to be used in combination with complementary silicone sealants on the same project without adhesion or compatibility issues.
What are the main application areas for this weatherproof sealant?
This sealant is designed for a wide range of building applications, including joint bonding and waterproof sealing between glass, stone, sun rooms, and plastic steel materials, as well as the installation and sealing of building doors, windows, and door and window glass assemblies.
What does "neutral curing" mean and why does it matter?
Neutral curing means the sealant releases neutral by-products (such as alcohol or oxime) during the curing process, rather than acidic compounds like acetic acid. This makes it non-corrosive to sensitive substrates such as metals, marble, and mirrors, and helps ensure long-lasting adhesion without damaging surrounding materials.
