The Everflex 500 Premium Bath and Sanitary Silicone Sealant C3 is a high-grade, moisture-curing acetoxy silicone sealant engineered specifically for high-humidity areas subject to condensation and water contact. Designed for professional plumbers, bathroom installers, and tilers, it provides an exceptional watertight seal around baths, showers, basins, wet rooms, and sanitary fixtures.
 
Formulated with powerful anti-fungal and anti-bacterial additives, this premium sealant actively inhibits the growth of black mold, mildew, and bacteria in damp environments, maintaining a clean and hygienic finish over years of use. It cures rapidly upon exposure to atmospheric moisture to form a permanently flexible, elastic rubber seal that readily accommodates the thermal expansion and structural movement of acrylic baths and shower trays without pulling away or cracking.
 
Supplied in a standard C3 cartridge format compatible with conventional caulking guns, it extrudes smoothly and bonds aggressively to non-porous surfaces including ceramic tiles, porcelain, glass, stainless steel, and painted or sealed wood. It serves as a dependable, industry-standard trade consumable for achieving a professional, durable, and mold-resistant seal in residential and commercial washrooms.
 
Tested to ISO 8339 and ISO 10590/10563.
