Joint & Seam Filler

Facts and Information

Joint & Seam Filler is a Fiber reinforced fill coat & seam treatment that creates flexible reinforcements.

Joint & Seam Filler is designed to fill openings and create transitions where flexible reinforcement is required to bridge larger gaps and provide continuous support of fluid-applied flashing membranes, waterproofing or air barrier components.

Joint & Seam Filler is a gun-grade crack and joint filler, adhesive and detailing compound that combines the best of silicone and polyurethane properties. This single-component, fiber-reinforced, silyl-terminated polymer (STP) is easy to gun, spread and tool. Use Joint & Seam Filler to fill openings and create transitions where flexible reinforcement is required to bridge larger gaps and provide continuous support of fluid-applied flashing membranes, waterproofing or air barrier components.

The Benefits of Joint & Seam Filler

Why use Joint & Seam Filler? Here are just a few benefits.

Suitable For All Climates

Joint & Seam Filler bonds directly to damp or dry surfaces and cures under a variety of weather conditions. May be fully exposed to UV and weather for up to 12 months.

Faster To Install

Dramatically reduces surface preparation time by eliminating the need for reinforcing tapes at sheathing joints, inside and outside corners.

A Healthier Solution

Solvent-free. Isocyanate-free. Phthalate-free. Passes the ASTM E84 Standard Test Method for Surface Burning Characteristics of Building Materials. LEED, Living Building Challenge and Cal Green Ready.

Advantages of Joint & Seam Filler

Joint & Seam Filler is a gungrade, crack and joint filler, adhesive and detailing compound that combines the best of silicone and polyurethane properties. This single-component, fiber-reinforced, Silyl-Terminated-Polymer (STP) is easy to gun, spread and tool.

Features:
