<p>Flexible filler for filling cracks, gaps or holes in masonry or a rendered finish on masonry, comprising a mixture of an acrylic caulk bulked up with a finely divided particulate material of a size to match the roughness of the surface around the crack gap or hole to be filled. The caulk and particulate material are mixed thoroughly to form a homogeneous mixture which is packed into a cylindrical cartridge having a nozzle through which the mixture can be forced when needed. Apparatus by which the contents of a conventional acrylic caulk filled cartridge can be replaced with the improved filler, comprising a holder for supporting the cartridge, means for forcing out the caulk contents of the cartridge into a container, means for adding particulate material to the caulk in the container, means for mixing the caulk and particulate material to form a homogeneous mixture, means for refilling the cartridge with at least some of the homogeneous mixture and means for reinserting a plunger into the cartridge, for subsequently forcing the filler from the cartridge to fill a crack, gap or hole.</p> |
