Definitions

  • the present disclosure is directed to the field of patching compositions, jointing compositions surfacing composition, and plastering compositions for surfaces.
  • the present disclosure is also directed to methods of making surfacing compositions of the above description, and to methods of their use.
  • surfaces including, but not limited to, finished surfaces and surfaces to be finished, commonly contain imperfections.
  • the surface is a painted surface (such as but not limited to a wall) or the surface is an unfinished surface that is to be painted.
  • a wall in a residential structure may contain nicks, holes or other imperfections as a result of daily activities and decorating. The foregoing nicks, holes or other imperfections are desirably repaired to maintain aesthetic qualities.
  • drywall and other materials are joined together by jointing compositions and imperfections in the drywall surface are smoothed using such compositions. Such imperfections are sometimes merely superficial, but may pose a hazard to the integrity of the material if a protective layer of paint or other finish is breached.
  • a patching composition generally referred to herein as a surfacing composition
  • the surfacing composition is applied to the imperfection, allowed to dry, and then finished as needed.
  • the finish is applied so as to match the original surface as closely as possible.
  • the surfacing compositions is generally further prepared, such as by sanding and priming, before the finish is applied.
  • surfacing compositions have certain drawbacks. Most surfacing compositions dry to a state that does not exactly match the original surface. As a result, when finished, the repaired surface does not match the original finished surface, revealing that the area has been repaired. For example, when surfacing compositions are applied to a painted surface, the repaired surface often has a shiny or glossy appearance. This sheen can only be eliminated through additional labor, but elimination of the sheen is not always possible with some surfacing compositions. The repaired area would be more aesthetically pleasing if the surface of the patch were "flat" in appearance so as to match the original surface. In addition, when surfacing compositions are used in construction to prepare unfinished surfaces, the area to which the surfacing composition is applied may be visible after the finish is applied. Furthermore, surfacing compositions are generally primed prior to painting, or the result will be inferior adhesion between the paint and the repair, leading to blistering, flashing, and other problems. Time and labor would be saved if no priming were necessary.
  • Alkyd paints are oil-based paints in which the diluent or thinner is typically (but not always) a mineral spirit and in which the binder is an alkyd resin.
  • Mineral spirits are volatile organic compounds (VOC). Once alkyd paint is applied to a surface, the mineral spirit evaporates, contributing significantly to VOC pollution. Proposed regulations would limit the use of alkyd paints formulated with VOC 3 and this will create a need for economical and safe methods of recycling these paints.
  • superior surfacing compositions are needed that allow the repair of a finished surface and the finishing of an unfinished surface such that the visibility of the surfacing composition is reduced as compared to prior art surfacing compositions or eliminated.
  • superior methods of recycling and reuse are needed for both alkyd paints and other types of paints.
  • the disclosure provides a novel surfacing composition and methods for using such a surfacing composition in repairing a finished surface, repairing an unfinished surface, and preparing an unfinished surface.
  • the surfacing compound may be used to plaster a surface, join/joint intersecting surfaces, and repair imperfections in a surface.
  • the surface is a painted wall.
  • other finished surfaces are within the scope of the present disclosure.
  • the unfinished surface is one or more sections of drywall; however, other unfinished surfaces are within the scope of the present disclosure.
  • compositions and methods it is an object of some embodiments of the compositions and methods to solve the problem of the difficulty of disposing of unneeded or used paint by incorporating the paint into a useful surfacing composition that does not require immediate disposal.
  • compositions and methods It is an object of some embodiments of the compositions and methods to provide surfacing compositions for repairing a finished surface and preparing an unfinished surface.
  • compositions and methods to eliminate or reduce (as compared to prior art surfacing compositions) the presence of distinguishing characteristics (such as but not limited to a sheen) that are apparent when a surfacing composition has been applied to a surface, including both finished and unfinished surfaces.
  • compositions and methods it is an object of some embodiments of the compositions and methods to provide a surfacing composition wherein a repaired surface displays no or reduced distinguishing characteristics (as compared to other surfacing compositions) indicating where composition has been applied or an unfinished surface displays no or reduced distinguishing characteristics (as compared to other surfacing compositions) indicating where the composition has been applied after the unfinished surface has been finished.
  • compositions and methods to solve the problem of the labor required to repair a finished surface and prepare an unfinished surface by providing a surfacing composition that requires no priming before being repaired or finished.
  • Alkyd as used herein means the class of binders formed by the condensation of polyhydric alcohols with polybasic acids.
  • Alkyd paint as used herein means an oil-based paint in which the binder is an alkyd.
  • “Fanning” as used herein means to direct a current of air upon a target.
  • “Finished Surface” as used herein means any surface that has been finished. Finishing can include painting, lacquering, shellacking, sealing, and the like.
  • Gramular as used herein means in the form of relatively small grains or particles. “Including” as used herein is non-exclusive, and can be read to mean “including but not limited to.”
  • plaster as used herein means to apply a composition as a coating or incrustation, and does not exclusively refer to the application of plaster,
  • Repair as used herein means to restore the surface to an even contour matching the areas around the repair.
  • “Sealer” as used herein means a finishing material, either clear or pigmented, that is usually applied directly over a surface for the purpose of sealing the surface.
  • "Unfinished surface” as used herein means a surface that would normally be finished after construction, preparation or repair, or a surface that one intends to finish after construction, preparation or repair, regardless of whether the surface is actually finished. Finishing can include painting, lacquering, shellacking, sealing, and the like.
  • the disclosure provides surfacing compositions for repairing a finished surface and preparing an unfinished surface.
  • Some embodiments of the compositions may be used as a volumizer in primer, increasing viscosity and aiding spreading. Such surfacing compositions are useful for jointing and patching imperfections in surfaces.
  • Various embodiments of the surfacing compositions disclosed herein have various advantages over previously known surfacing compositions.
  • Various embodiments of the surfacing compositions have at least one of the following advantages: they dry rapidly after application to a surface; they do not require priming prior to painting; they can be applied to a wide variety of surfaces; they display good adhesion properties; they present a surface without observable characteristics (such as but not limited to a sheen) that identify the location of the composition; and they provide a means for recycling waste paint.
  • the surfacing composition of the present disclosure comprises dried paint.
  • the dried paint may be granular in nature.
  • the granular dried paint can be obtained from any source.
  • the granular dried paint can be obtained from a previously painted surface.
  • the granular dried paint is obtained by removing paint from a previously painted surface and grinding the paint to generate a granular product.
  • impurities are removed from the dried paint prior to combining the dried paint with the sealer.
  • the granular dried paint is further dried after removal from the previously painted surface by any of the drying methods described herein.
  • the granular dried paint can be obtained by drying and grinding a liquid paint.
  • the liquid paint can be from any source, including overspray, paint purchased in excess of that needed for a job, paint manufactured in excess of orders, and paint that has been stored for a period of time exceeding its acceptable shelf-life.
  • the paint can be an acrylic (water-based) paint or an oil-based paint, including an alkyd paint. Alkyd paints have the advantages of drying quickly and grinding well.
  • the paint can be dried by any appropriate method known by those skilled in the art, including heating, low pressure, or farming (alone or in combination),
  • the liquid paint is dried by exposure to air at ambient temperature.
  • the liquid paint is dried by fanning the paint.
  • Fanning can be achieved using any appropriate fan or blower, including even a typical handheld hair drier for small batches. Larger fans and blowers can be used as well.
  • the paint may be heated during fanning. Heat may be transferred to the paint by conduction (for example, heating the vessel containing the paint), convection (for example, heating the air around the paint, as in an oven), or radiation. Heat may be transferred to the paint by heating the air with which the paint is fanned, for example by using a heated blower. If fanning is used, air must be fanned over the paint at a sufficient rate to facilitate drying.
  • Drying may be achieved by heating alone, or by heating in combination with fanning as explained above.
  • the paint When heat is used to achieve drying, the paint may be subjected to any temperature above the paint's freezing point at the pressure under which heating occurs. If heating occurs in the presence of diatomic oxygen (or another strong oxidant), then the paint may be dried at a temperature below its flash point.
  • Alkyd paint typically has a flash point of about 100° F (200° F surface temperature with air movement). As a result, in embodiments of the surfacing composition in which a liquid alkyd paint is dried, drying should occur at temperatures below about 100° F.
  • alkyd paint may be dried at a temperature at or above about 100° F.
  • the safe flashpoint of the particular alkyd paint under a particular concentration of diatomic oxygen can be determined by one skilled in the art without undue experimentation.
  • acrylic paint has a higher flash point than does alkyd paint. Accordingly, in some embodiments of the surfacing composition comprising acrylic paint, drying can be conducted at higher temperatures. Various embodiments of the surfacing composition employ drying temperatures of about 100-750° F, about 200-600° F, about 250-500° F and about 500° The temperature may be varied during a given batch. Employing reduced pressure or fanning at a given temperature will achieve faster drying. Oxygen may be reduced or excluded from the air around the paint during drying. The pressure may be varied to achieve drying, alone or in combination with heating or fanning.
  • the dried paint may be ground by any appropriate method known by those skilled in the art.
  • the dried paint may be ground by any of the following: a rotary mill, a ball mill, a rod mill, a mortar and pestle, a SAG mill, a pebble mill, an autogenous mill, a Buhrstone mill, grinding rolls, a colloid mill, a disk mill, an edge mill, a hammer mill, and a Wiley mill.
  • dried paint may be ground in a household food processor, or a kitchen blender.
  • the granular dried paint is a mixed alkyd/acrylic granular dried paint. Because alkyd paint is generally volatile and has a low flash point, it is advantageous to mix liquid alkyd paint with a dried acrylic paint, as this allows formation of a dried paint without heating the alkyd paint. The dilution of the alkyd paint can also facilitate safer disposal.
  • Such a mixed alkyd/acrylic granular dried paint may be formed by combining a granular dried acrylic paint with a liquid alkyd paint to form a wet paste, drying the wet paste to form a dried paste, and grinding the dried paste.
  • the term "dried paste” in this sense is not limited to a substance that retains the properties of a paste (although in some cases the dried paste will retain the properties of a paste), but refers to the product of drying the wet paste.
  • the granular dried acrylic paint can be produced by any method described herein. In some embodiments of the composition, the volumetric ratio of the granular dried acrylic paint to liquid alkyd paint is about 3:1 or exactly 3:1.
  • the composition can be successfully formulated up to 95% dried acrylic patent and as low as 5% alkyd paint.
  • the dried paste can then be ground using any of the approaches described herein, to form the mixed alkyd/acrylic granular dried paint.

  • the wet paste may be blended during drying. Blending can occur for as long as necessary to achieve adequate mixing and drying. In some circumstances this can be achieved in about two minutes. Such blending can be achieved by a person of ordinary skill in the art without undue experimentation.
  • the granular dried paint is combined with the sealer after drying without further processing.
  • the granular dried paint is segregated based on particle diameter prior to combining with the sealer.
  • the granulated dried paint may be segregated by any means known in the art to ensure consistency of the grain size.
  • segregation is performed to produce a granular dried paint with a consistency approximating that of flour.
  • the paint is first sifted with a #80 sieve; the retained fraction ("retentate") of the #80 sieve is further sifted through either of a #20 sieve or a #25 sieve.

Abstract

Composition de surfaçage faite de peinture recyclée n'exigeant aucun apprêt, donnant une apparence « lisse » et non réfléchissante, et partiellement constituée de peinture séchée. Cette composition est une application utile pour les peintures ménagères usagées ou en excédent qui exigeraient sinon des procédés spéciaux pour les éliminer et créent potentiellement des problèmes de nettoyage de substances toxiques. Cette composition consiste en peinture séchée granulaire et en un enduit à base d'eau, et elle s'étale sur une surface pour en réparer les imperfections. On peut ainsi obtenir une finition de surface sans qu'aucun apprêt ne soit nécessaire. Grâce à l'apparence lisse de cette composition, on ne voit aucune brillance particulière à l'emplacement où a été opérée la réparation. Cette composition est un moyen simple de recycler de la peinture et constitue également un moyen simple et économique de réparer les imperfections d'un mur ou d’une autre surface tout en évitant l'étape d'application d'un apprêt à l'emplacement de la réparation avant de peindre ou de repeindre.
