Ultimate Waterproof Sealant for Home and Outdoor Surfaces

WELLUCK White Sealant Silicone

Waterproof Sealing: WELLUCK white sealant silicone provides unparalleled waterproof protection, safeguarding against water leaks, odors, UV rays, extreme heat, and pressure. It is 100% waterproof for indoor, outdoor, and underwater surfaces, making it ideal for a wide range of applications, including metal, tile, ceramic, stone, wood, glass, and concrete.

Long-Duration Protection: Our reinforced white caulk is rated to offer protection against high heat, corrosion, leaks, and acids for up to 15 years. It effectively resists black spots and stains, ensuring clean and long-lasting results.

Clog-Free Application: The clog-free thermoplastic nozzle ensures smooth application. Just cut the main opening of the bottle, install the nozzle, and bevel the opening. With the right viscosity, the sealant flows smoothly—neither too runny nor too clumpy. It’s 100% pure silicone without fillers.

Zero-Shrinking and Durable Flexibility: WELLUCK windows silicone caulk features excellent adhesion and long-lasting flexibility. It won’t shrink or crack, even under extreme weather conditions, from -40°F to +104°F, including cold, heat, UV, and constant raindrops.

Rapid Setting and Curing: The sealant sets in 30 minutes, firm in 24 hours, and fully cures in 48 hours. For optimal results, apply in a dry construction environment at 75°F. Our bathtub caulk delivers smooth, uniform sealing with no chemical odor.

Quick Drying and Safe Usage: After 30 minutes, the surface dries sufficiently for further application or decoration. Full curing occurs in 48 hours. For best results, use the caulk within 3 days after opening.

Use Guidelines: When filling the caulk tube, some overflow and dry traces may occur. This is normal and can be ignored.
