Definitions
- the present invention relates generally to multi-component powdered compositions, and more specifically to packaged additives for settable powder compositions such as, but not limited to wallboard joint compound.
- Walls and ceilings made from gypsum wallboard are conventionally constructed by attaching the wallboard panels to framing members or studs, and filling and coating the joints between the panels with a specially formulated paste composition called a joint compound.
- Joint compounds may be supplied as powdered compositions (to be mixed with water at the jobsite) or may be premixed with water at the factory to yield a ready mixed (or paste) joint compound.
- a paste joint compound (Taping grade) is placed within and over the joint formed by the abutting edges of the wallboard panels, and a paper reinforcing tape is embedded in the joint with the joint compound which is then permitted to dry.
- the reinforcing tape may be of non-cellulose composition, but of a size and shape similar to strips of paper joint tape.
- the reinforcing tape may be of a fiberglass weave requiring the use of chemically setting type joint compounds.
- a second joint compound (Topping or
- Finishing grade is applied over the joint, and it too is permitted to dry. It is usually necessary for a third application of a joint compound and, after the third coat is dry, it may be lightly sanded and may be conventionally finished with a decorative material (paint, texture or wallpaper) then applied to the wall. All three coats of joint compound may alternately be applied with an All Purpose grade of joint compound.
- joint compounds There are several categories of joint compounds. Drying type compounds harden through the evaporation of water, whereas setting type joint compounds chemically react with water during the curing process.
- Setting type joint compounds typically use calcium sulfate hemihydrate, also known as stucco or plaster of Paris, as a base. When water is added to the setting type powder, it reacts with the calcium sulfate hemihydrate via a hydration reaction to form an interlocking matrix of calcium sulfate dihydrate crystals. The interlocking crystal matrix gives the compound increased strength.
- the benefit of a setting type joint compound over a drying type is the overall strength of the finished joint, resulting in less shrinking and cracking, as well as an independence from having to wait for the joint compound to be completely dry prior to further finishing. Drying type joint compounds have the advantage of ease of use, as they typically come in a ready mixed form, with water being added and mixed by the manufacturer.
- a third type of joint compound combines the setting action of a calcium sulfate hemihydrate based compound with the ease of use of a ready mixed compound.
- Ready mixed joint compound is typically supplied to the customer in either cardboard cartons or plastic pails in units having volumes of 3.5 to 4.5 gallons (13.25-17.03L). Joint compound is supplied at a viscosity typically higher than what is applied at the jobsite. This allows the contractor to mix in additional water using a power drill and mixing paddle to achieve the desired application viscosity.
- Ready Mix joint compound production is typically accomplished by blending the wet and dry ingredients in a mixer until smooth, adjusting the viscosity to a desired level through water addition, then filling and sealing containers to be shipped to customers. This process can be disrupted by use of ingredients which thicken very rapidly and take longer periods of time to fully wet out and drop in viscosity, leaving the combined wet and dry ingredients in the mixer competing for water through the typical mixing cycle and at a higher than desired viscosity.
- the above process results in mechanical limitations and problems such as binding of the wet mixer and overloading of the mixer motor.
- the higher than desired viscosity at the completion of the mixing cycle affects the ease of pumping and moving the material out of the mixing system and through the packaging line and also interferes with the lidding and closing of the container. It is known to provide selective performance enhancing additives to the joint compound mixture during formulation at the jobsite to enhance performance characteristics. In some cases, the set or dry time is
- viscosity and/ or dust generation during sanding are characteristics that are influenced by additives to the mixture.
- US Patent No. 6,476,099 discloses the addition of surfactant additives to joint compound to generate performance with improved cracking, improved shrinkage and reduction of surface finish defects after application to wallboard surfaces.
- US Patent Nos. 6,228, 163 and 5,746,822 incorporated by reference disclose joint compounds formulated with a base joint compound that is relatively inert until an extra additive is provided, functionally serving as an activator.
- the present additive packaging system including providing separately packaged additives for use with a base joint compound or other powder or settable composition in a main container, so that the user can adjust the properties of the joint compound or desired composition during mixing.
- a base joint compound or other powder or settable composition in a main container, so that the user can adjust the properties of the joint compound or desired composition during mixing.
- small flexible packages in the form of a tear pouch or stick pack contain designated amounts of additives for drywall finishing products that allows the user to add an additive to achieve a desirable trait or characteristic in the resulting joint compound.
- This packaging allows for pre- portioned, small amounts of additives that can be easily distributed to a consumer that allows them to add the additive to a drywall finishing product such as a joint compound, drywall patching compound, plaster, etc.

- a main container 12 is typically a plastic bucket or tub of the type used to package ready mix wallboard joint compound, and includes a bottom 14, an annular sidewall 16 and an upper lip 18, all integrally formed, as by being made of molded plastic, and combining to define an internal chamber 20.
- Other materials are contemplated for the container 12, including but not limited to metal and cardboard.
- a supply of ready mix joint compound 22 substantially fills the internal chamber 20.
- the base joint compound 22 is the ready mix type, it is also contemplated that powder or setting type joint compound is suitable.
- the internal chamber 20 is covered by a removable container lid 24 that engages the upper lip 18 and latches closed upon the main container 12 using plastic clips or connectors (not shown) on the exterior of the container as are well known in the art.
- a feature of the present system 10 is that an underside 26 of the container lid 24 is provided with a compartment or additive container 28 constructed and arranged to retain at least one and preferably a plurality of
- the additive container 28 is preferably made of the same material as the lid 24 and is configured so that prior to use, the additive packages 30 are isolated from the base joint compound 22, as well as from the internal chamber 20, and are protected from exposure to moisture prior to the ultimate mixing of the additive packages with the joint compound 22.
- Contemplated additives 32 suitable for separate packaging in the present water soluble additive packages 30 include, but are not limited to retarders, accelerators, activators, dust reducers, pigments, adhesion promoters such as powdered adhesive, including polyvinyl alcohol or polyvinyl acetate and the like.
- the state of the packaged additive 32 is contemplated to be liquid, solid or powder.
- a lower wall 34 of the additive container 28 is frangible, as by scoring, perforations, having a thinner wall thickness, or the like.

- FIGs. 4 and 5 another embodiment of the present joint compound additive system 10 is generally designated 40.
- a main distinctive feature of the system 40 is that the additive packages 30 are secured within a designated additive container 42 which is separate and isolated from the main container 12.
- the additive packages 30 in the system 40 have the same characteristics as in the system 10.
- the packages 30, when provided in a water soluble format, are prevented from being exposed to moisture, which would cause them to prematurely dissolve and release the additive 32.
- the additive container 42 includes a bottom 44, an annular wall 46 and an upper lip 48, all preferably integrally joined, as by being made of molded plastic.
- a lid 50 covers the upper lip 48 and encloses an additive cavity 52 that encloses the additive packages 30 and retains the additive 32 in inactive status until it is needed for use.
- the additive container 42 is opened and the at least one and preferably a plurality of additive packages 30 are deposited into the main container 12, where the packages 30 are dissolved and the additive 32 is mixed into the main joint compound 22.
- the powered mixer 36 is used as needed.
- the user tears or cuts open the package 30 and manually empties the additive 30 into the base joint compound 22, where the additive is mixed in as is known in the art.
- the user places a water soluble additive package 30 into the main container 12, and adds sufficient water to dissolve the package in water to mix with the packaged powder or ready mixed joint compound 22 to achieve the desired joint compound.
- a water soluble additive package 30 into the main container 12, and adds sufficient water to dissolve the package in water to mix with the packaged powder or ready mixed joint compound 22 to achieve the desired joint compound.
- packages 30 or pods are contemplated as being provided in the sealed container 28 or 42, thus reducing the mess and dust generated while mixing conventional powder-based, setting type joint compounds.
