Injection Foam 11 oz. Single Cartridge

This two part urethane foam is a special low-viscosity formulation that flows readily to all parts of crack before reacting with moisture to expand. Once expanded the permanently flexible closed cell foam does not shrink, thus effectively filling even larger voids such as those around skimmers. Foam is inert when cured and thus safe to the environment. Unique Single Cartridge System can be applied with a standard caulk gun.

Mixer tips (#CAMB10) are purchased separately and do not come with foam.
