The 3C Sealants Matt Silicone is a premium, neutral-curing sealant tailored for homeowners and trade professionals who prioritize aesthetics alongside durability. It is specifically designed to provide a high-end, completely non-sheen matt finish for natural stone and external facades, while its integrated anti-mould additives make it an excellent choice for moisture-prone areas like kitchens and bathrooms. While it offers superior structural performance, users should note that the specialized matt texture may require careful application technique compared to traditional high-gloss silicones to ensure a uniform appearance.

Ensure the surface is completely degreased and dry. Check if the substrate material is compatible with neutral-cure silicone.
Ensure the product is smoothed with a professional sealant profiling tool immediately after application rather than using fingers.
To ensure optimal performance, surfaces must be clean, dry, and free from dust, grease, or previous sealant residues. Use a high-quality caulking gun for even application. For a clean finish, apply masking tape to both sides of the joint before extruding the sealant, then smooth it with an appropriate profiling tool within 5-10 minutes.
Compatibility: It is ideal for natural stone, concrete, brick, and standard bathroom/kitchen substrates. Avoid applying in temperatures below 5°C or above 40°C. Once cured, the sealant requires no special maintenance other than standard non-abrasive cleaning to maintain its matt finish.
