Sealit

Sealit is a brand name used for a line of sealant products intended to seal joints, gaps, and interfaces to prevent air, water, and moisture intrusion. The brand appears in construction, automotive, and consumer hardware retail contexts, and is used by several manufacturers in different regions. While the specific formulations and standards vary by producer, the core concept is to provide durable, flexible sealing between dissimilar materials.

Product range typically includes silicone-based sealants for high flexibility and weather resistance; polyurethane sealants that offer strong adhesion and long-term durability; and acrylic sealants for interior use and paintability. Some products are solvent-based, others water-based, and many are sold in cartridges or tubes designed for standard dispensing guns. Several variants advertise low VOC content, mold and mildew resistance, or high temperature tolerance.

Common applications include sealing around windows and doors, bathtubs and showers, sinks, roofs, expansion joints, and automotive glazing. For exterior applications, weather resistance and UV stability are important; for interior use, ease of toolability and paint compatibility may be emphasized.

Usage typically involves surface preparation, priming when required, applying the sealant in a continuous bead, and allowing it to cure according to the product data sheet. Cure times range from a few hours to several days depending on formulation and ambient conditions.

Market presence. Sealit products are commonly distributed through hardware retailers, building supply stores, and professional contractors. Regulatory considerations often address volatile organic compound (VOC) content, environmental impact, and suitability for specific substrates.

Notes: Brand identity and product features vary by producer and region; consumers should consult the local data sheets for exact specifications.
