Acrylic Urethane Elastomeric Sealant and Precision Hand Dispenser Refill

The Finish Line Caulk Precision Hand Dispenser Refill Kit is a compatible product that can be purchased separately. Finish Line Caulk is a one-component, high-performance, gun-grade, urethane-modified acrylic sealant that is internally plasticized. This premium technology reduces dirt pickup, eliminates yellowing, and prevents shiners. Requiring no mixing or priming, Finish Line Caulk can bond to a wide range of substrates, including crown molding, windows, trim, doors, sinks, counters, siding, penetrations, stucco, EIFS, hardboard, and flashing.

Finish Line Caulk boasts superior adhesion, durability, and an impressive 800% elongation. It forms a flexible, durable, airtight, and water-resistant seal, offering exceptional protection from environmental conditions. Once cured, the bead exceeds the requirements of Federal Specification TTS-00230C, Type II, Class A; ASTM C-920, Grade NS, Class 25; and ASTM C-834 Type OP, Grade -18°C.

The Finish Line Caulk system features soap and water clean-up, and its patented design creates a small, even, and controlled bead of caulk, making it perfect for fine lines, small gaps, cracks, and hard-to-reach places. The ergonomically designed handle minimizes hand fatigue, and the compact size makes it portable and convenient.

Finish Line Caulk is ideal for a variety of applications, including hard-to-reach areas, hobbies, crafting, crown molding, baseboards, windows, gutters, counters, cement, metal siding, roofs, small gaps and cracks, RVs, nail holes, and quick repairs. It is a weather-tight, indoor/outdoor sealant that is water-resistant and paintable in 4 hours, with no mixing required.

The Finish Line Caulk Refill Kit comes in a micro-sized tube with tips, providing the ultimate in portability, convenience, and precision. It is perfect for small jobs and hard-to-reach areas, making it easy to use. The product bonds to most substrates, exceeds ASTM C-920 Class 25 requirements, and offers up to 800% elongation. However, it is not recommended for marine or underwater use.
