Q
Is this sealant safe to use on porous natural stones like marble and granite?
Yes. This sealant is specifically formulated to be non-staining and non-polluting, making it fully safe for porous natural stones including marble, granite, limestone, and travertine. Its chemistry prevents any oils or discoloring substances from migrating into the stone surface.
Q
Why is a neutral-cure formulation important for stone curtain wall applications?
Neutral-cure silicone sealants do not release acetic acid or other corrosive by-products during curing. This is critical for stone curtain walls because it eliminates the risk of corrosion to embedded metal fixings and prevents chemical staining or damage to adjacent sensitive materials.
Q
What substrates can this sealant adhere to besides natural stone?
In addition to marble, granite, limestone, and travertine, this sealant offers excellent adhesion to concrete, anodized aluminum, powder-coated aluminum, glass, and treated wood — making it highly versatile for complex façade and curtain wall assemblies.
Q
Can this sealant handle thermal movement and structural settling?
Yes. The sealant forms a flexible yet tenacious bond that is specifically designed to accommodate natural thermal expansion and contraction as well as structural settling in buildings, ensuring long-term weatherproof performance without cracking or debonding.
Q
Is this a one-component product, or does it require mixing before use?
This is a one-component silicone sealant, meaning it requires no mixing and is ready to use directly from the cartridge. It cures upon exposure to atmospheric moisture, simplifying the application process on-site.
Q
Is this sealant suitable for exterior weatherproofing applications?
Absolutely. This sealant is specially designed for weatherproof sealing of stone assemblies and curtain walls exposed to outdoor environments. It provides durable resistance to UV exposure, rain, temperature fluctuations, and wind-driven water infiltration.
