The tool comprises a foam block bonded to a rigid backing block. The tool is pressed against the wall, whereupon the foam conforms to, and forms a seal to, the wall surface. A conical recess is provided in the backing block for receiving the nozzle of a caulking gun, and a through-hole conveys sealant, injected under pressure, through the tool and into the crack. A rigid spigot may be provided for positioning the apparatus correctly relative to prepared recesses along the length of the crack.
