Gorilla 100% Silicone Caulk, Waterproof Sealant, 2.8oz Squeeze Tube, White

Gorilla 100% Silicone Caulk is a waterproof white sealant designed to tackle small household gaps, fixtures, and joints. Packaged in a compact 2.8oz squeeze tube, it offers an accessible format for homeowners and renters handling quick repairs without loading a full-sized caulking gun. It creates a tight seal against air, moisture, and water across a wide range of kitchen, bathroom, and building materials.

A key advantage of this formula is its quick turnaround time. It can handle water exposure in as little as 30 minutes, allowing you to seal sinks, showers, or tubs without keeping them out of service for extended periods. Once fully cured, the 100 percent silicone formulation works both indoors and out, holding up rain or shine across temperature variations without shrinking, cracking, or turning yellow over time.

Longevity is reinforced by a 10-year mold and mildew resistance profile, making it a strong match for high-humidity areas like porcelain tiles, granite countertops, and plumbing fixtures. Surface versatility is extensive, bonding to glass, wood, metal, drywall, stone, laminate, and painted surfaces. However, the compact 2.8-ounce squeeze tube holds a limited amount of material, making it better suited for targeted touch-ups rather than whole-room renovations or extensive siding installations.

Verdict: Gorilla 100% Silicone Caulk is an excellent pick for anyone who needs a dependable, fast-setting waterproof seal for minor repairs. Its reliable adhesion and 10-year mold resistance make it ideal for quick bathroom, kitchen, or window fixes.

• Need a fast-acting sealant that can take water exposure in 30 minutes
