Abstract
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.

- 47. A flexible filler by which cracks, gaps or holes in masonry or a rendered finish can be filled prior to painting so as to hide the existence of the crack, gap or hole, comprising a mixture of an acrylic caulk and finely divided particulate material of a size to match the roughness of the surface around the crack gap or hole to be filled, wherein the caulk and particulate material are mixed thoroughly to form a homogeneous mixture and the mixture is packed into a tube having a nozzle through which the mixture can be forced by pressurising the contents of the tube.

54. A method of creating a flexible filler by which cracks, gaps or holes in masonry or a rendered finish on masonry can be filled prior to painting so as to hide the existence of the crack, gap or hole, comprising the steps of mixing flexible acrylic caulk and particulate material of a size to match the roughness of the surface around the crack, gap or hole, and in correct proportions, stirring thoroughly to form a homogeneous mixture, and packing the mixture in a tubular cartridge, from which it can be forced through a nozzle as required, just prior to application.
- 61. Apparatus to enable the contents of a conventional acrylic caulk filled cartridge to be replaced by a filler mixture by which cracks, gaps or holes in masonry or a rendered finish on masonry can be filled prior to painting and comprising a mixture of an acrylic caulk and finely divided particulate material of a size to match the roughness of the surface around the crack, gap or hole, comprising a holder for supporting the cartridge, ejector means for forcing out the caulk contents of the cartridge into a container, means for adding particulate material to the caulk in the container, mixing means for mixing the caulk and particulate material to form a homogeneous mixture, withdraw means for removing the plunger from the cartridge, filling means for refilling the cartridge with at least some of the homogeneous mixture and insertion means for reinserting the plunger into the cartridge.
- 63. A method of mixing ingredients to form a flexible filler by which cracks, gaps or holes in masonry or a rendered finish can be filled prior to painting, and storing same ready for use, comprising the steps of removing acrylic caulk from a pre-filled cartridge thereof, mixing water with particulate material, mixing the caulk, water and particulate material to form a homogeneous mixture and refilling the cartridge therewith, for subsequent dispensing through a nozzle attached to the end of the cartridge.
-
65. A method of mixing ingredients to form a flexible filler by which cracks, gaps or holes in masonry or a rendered finish on masonry can be filled prior to painting, and which comprises a mixture of an acrylic caulk and finely divided particulate material of a size to match the roughness of the surface around the crack, gap or hole, wherein water is supplied to a mixing region before, during or after the supply of particulate material thereto, a mixing aid therein is operated to mix the water and particulate material, whereafter acrylic caulk is introduced into the mixing region for mixing therewith, to form a homogeneous mixture prior to being loaded into an empty cartridge.
-
66. A container filled with flexible filler by which cracks, gaps or holes in masonry or a rendered finish on masonry an be filled prior to painting, and comprising a mixture of an acrylic caulk and finely divided particulate material of a size to match the roughness of the surface around the crack, gap or hole, from which air is evacuated when it is sealed after filling (and resealed after use) to prevent the acrylic material from curing, as it will do if exposed to air.
-
67. A container filled with flexible filler by which cracks, gaps or holes in masonry or a rendered finish on masonry can be filled prior to painting, and comprising a mixture of an acrylic caulk and finely divided particulate material of a size to match the roughness of the surface around the crack, gap or hole, comprising a squeezable tube which can be systematically squeezed to move the mixture from one end to the other, to mix the caulk and particulate material to a smooth paste prior to discharging the mixture for filling an opening.
-
68. A flexible filler by which cracks, gaps or holes in masonry or a rendered finish on masonry can be filled prior to painting, which comprises a mixture of an acrylic caulk and finely divided particulate material of a size to match the roughness of the surface around the crack, gap or hole, wherein mixing the particulate material with the acrylic caulk bulks up the latter and results in a mixture having more body to it than does the basic acrylic caulk, so that the resulting mixture is thicker in consistency and will tend to remain where it is located in a crack, gap or hole.
