Kraken Bond RTV Silicone Caulk Clear - Durable Waterproof Sealant

In this review of Kraken Bond RTV Silicone Caulk Clear the bottom line is straightforward: this 100% silicone sealant is aimed at DIYers and professionals who need a clear, weatherproof bead that stays elastic over time. The biggest reason to buy is its lasting flexibility and waterproof performance across a range of surfaces, making it a reliable choice for kitchen sinks, bathroom fixtures, windows and doors. The reviewer found it produces an invisible finish when applied cleanly, while noting there are tradeoffs in odor and ease of tooling for some users.

Key Features

• Crystal Clear Finish: The transparent formula provides an almost invisible seal that is ideal for visible joints around sinks, showers and glass without altering the look of the surface.
• Permanently Elastic: The 100% silicone base stays flexible after curing so joints move with temperature changes and seasonal expansion without cracking.
• Superior Adhesion: Bonds well to nonporous surfaces such as glass, porcelain and steel, making it useful for plumbing, fixtures and window glazing.
• Waterproof and All-Weather: Designed to maintain a waterproof barrier in wet areas and outdoors, resisting temperature extremes to remain effective year-round.
• Low VOC Consciousness: The formulation meets VOC specifications for safer indoor use around sockets and enclosed spaces when used as directed.

Who It's For

Kraken Bond clear silicone is a solid pick for homeowners, handymen and contractors who need a long-lasting, transparent seal for bathrooms, kitchens, aquaria or exterior trim. It works best when used on clean, nonporous surfaces like glass, steel and glazed tile where a neat, invisible joint is desired.

Those who should look elsewhere include users who are extremely sensitive to strong chemical odors or novices expecting a forgiving, easy-to-tool product; some customers report a strong smell and a learning curve with application. If paintability is required, choose a paintable hybrid product instead of a pure silicone.
