A material provides a coloured difference to that of the base compound is added to the base compound to thereby aid in identifying the joining composition.
Description
1 A PLASTER JOINTING COMPOUND Technical Field The present invention relates to jointing compound and more particularly but not exclusively to plaster jointing compound. 5 Background of the Invention Interior lined walls typically consist of plasterboard sheets attached to framing with fasteners and adhesive. The resulting joints are then concealed with several layers of jointing compound before being painted. The first layer of jointing compound is usually plaster based and reinforcing tape is bedded into this layer, adding extra strength to the io joint. Subsequent layers of jointing compound build up the joint, making it wider and thicker. Finally the surface is sanded. This blends the layers of compound with the board surface ready for painting. Depending on the final finish required, extra care must be taken in order to make the final joint truly invisible. Construction of these joints is a defined process, with established, industrially accepted methods. Problems result when 15 deviations from those methods occur. Warrantee claims in respect of failed plaster joints cost many tens of thousands of dollars per year. In the case of jointing compounds these claims are almost always to do with the first bedding layer. In combination with the jointing tape, this layer should provide most of the strength in the final joint. Typical problems include lack of paper 20 tape adhesion, with resulting tape fall-out. Cracking of the joint, discoloration of the joint and a weak and powdery joint are also potential problems. When handling these claims several factors are considered. * Establishing the product manufacturer. * Establishing what type of product was used. 25 e Establishing if the products were used correctly (regardless of manufacturer). This will involve laboratory tests to determine if adulterants were added. An examination of the finished work is also done, to make sure it has set, dried and adhered as it should. The vast majority of problems encountered involve the last cause, when poor 30 practice has lead to problems. However the majority of cases can be dealt with by dealing with the first cause. One of the complicating factors when determining which compound was used is that after application, many of the jointing compounds appear very similar. This is because many brands and types of jointing compound have similar ingredients. 35 Accordingly not being able to identify the manufacturer of the product is a disadvantage of currently available jointing compounds.
2 Object of the Invention It is the object of the present invention to overcome or substantially ameliorate the above disadvantage. Summary of the Invention 5 There is disclosed herein a plaster composition to join edge portions of adjacent sheets, the composition including: a plaster base compound that is flowable when pressed to provide for application thereof to the edge portions to provide a joint, the base compound being settable and having a predetermined colour; and to a fluorescent material mixed with the base compound and being visually distinguishable from said predetermined colour to thereby aid in identifying the jointing compound. Preferably, the compound is a topping composition that is sandable when set. Preferably, said fluorescent material is a dye, ink or pigment. is Preferably, the fluorescent material is a powder having particle sizes in the range of 2um to 500um. Preferably, said fluorescent material is provided by short fibres of 0.01mm to 4mm in length. Preferably, said fluorescent material is excited with any UV light. 20 Preferably, said fluorescent material is a dyed/pigmented melamine, sulphonamide, formaldehyde copolymer. Preferably, the fluorescent material has a particle size of 3 micron to 500 micron. Preferably, said fluorescent material comprises 0.00001% to 1% by weight of the jointing topping compound. 25 Preferably, said fluorescent material is 0.001% to 0.05% by weight of the jointing or topping compound. Preferably, said fluorescent material is either red, blue or yellow. Preferably, the fluorescent material offers a red, blue, green, yellow, or orange, fluorophore fluorescence. 30 Preferably, said composition is self supporting so as to remain in position between the edge portions until set.
3 Detailed Description of the Preferred Embodiments Preferred of the present invention will now be discussed by way of example with reference to the following examples. A plasterboard jointing composition incorporating a preferred form of the 5 present invention includes a base plaster jointing compound including approximately 65% plaster (CaSO4.1/2 H20), and minor amounts of Mica, Talc, PVOH, cellulosic thickeners, and calcite (CaCO3). The jointing composition is flowable when pressed to provide for application to adjacent edge portions of adjacent plasterboard sheets, whether the edge portions are io vertically or horizontally extending as in the case of walls and ceilings. The composition is settable so as to be sandable. However the composition also needs to be "self supporting" so as to remain in place until it is set. Added to the base compound is an identifying material that can provide a colour indicative of the manufacturer of the jointing composition. For example to provide the is colour, the colour may be a coloured material such as a dye or pigment. As an alternative the material may be a fluorescent additive and may comprise 0.0001 to 0.05% by weight of the jointing compound. The colour providing material may be in powdered form or may consist of short fibres. If a powdered material is provided preferably the particle size would be from 20 about 2um to about 500um, while if short fibres, preferably the fibres would be 0.0 1mm to 4mm in length. If the colour providing material is fluorescent, preferably it would be excited with any UV (365nm) light. In a further example, the fluorescent material may be a fluorescent tracer such as a dyed/pigmented melamine sulphonamide, formaldehyde copolymer (a coloured-highly 25 fluorescent pigment coated in plastic to render it inert). Typically the fluorescent material would have a particle size of about 3um to about 500um. Again as an example, the fluorescent would be 0.00 1% to 0.01% by weight of the jointing compound. If a fluorescent material is employed it is preferably excited by a short wave long wave combination lamp having an 8 watt tube operating at typically a long 30 wavelength of 365nm. As a further alternative, the colour providing material may be a colourless fluorescent fibre of 0.3 to 4mm in length that when excited appears red, blue or yellow. In use of the above described jointing composition, after it has set, it is possible to identify the manufacturer of the jointing composition by inspecting the jointing 35 composition and exposing it to, for example, UV light. If the composition is of a certain colour, then the manufacturer can be identified. The added pigment used in the present 4 invention is intended to be invisible to the naked eye, under natural lighting. However, it fluoresces and becomes visible when exposed to UV lighting. In a first example of the present invention, there is provided a plaster based jointing composition comprising: s Plaster 1%-80% Calcite 0%<30% Mica 0%<5% Talc 0%<10% Polyvinyl alcohol 0%<5% 1o Sorbitol 0%<5% Cellulosic thickener 0%<5% Clay 0%<5% Perlite 0%<10% Starch 0%<10% 15 Accelerator 0%<0.5% Retarder as required Fluorescent pigment 0.00001-1%. In a specific example of the plasterboard jointing composition, the composition composes: 20 Plaster 50-80% Calcite 10-30% Mica 1-10% Talc 1-10% Polyvinyl alcohol 0.1-5% 25 Sorbitol 0.01-5% Cellulosic thickener 0.01-5% Attapulgite clay 0.01-5% Accelerator 0.001-0.5% Retarder as required 30 Fluorescent pigment 0.00001-1% The abovementioned jointing composition is generally applied in a first and a second layer to adjacent edge portions of plasterboard. These layers provide strength to the joint and are usually reinforced with paper tape or fibreglass tape. These layers are not usually sanded, but are scraped back in preparation for the next layer (topping layer) 35 which is sandable. This topping layer is provided by a "topping" composition.
5 In another preferred form, the present invention provides a topping composition comprising: Water 1%-50% Calcite 1%-60% 5 Mica 0%<20% Talc 0%<30% Polyvinyl acetate 0%<20% Cellulosic thickener 0%<5% Clay 0%<5% 10 Polyvinyl alcohol 0%<5% Acticide 0%<5% Perlite 0%<10% Fluorescent pigment 0.00001-1% More preferably the topping composition comprises: is Water 20-50% Calcite 20-60% Mica 0.1-20% Talc 0.1-30% Polyvinyl acetate 0.1-20% 20 Cellulosic thickener 0.01-5% Attapulgite clay 0.01-5% Polyvinyl alcohol 0.001-5% Biocide 0.001-5% Perlite 0.001-10% 25 Fluorescent pigment 0.00001-1%
