Description
COLOURING OF PLASTER
This invention relates to the colouring of plaster and the like and, in particular, the preparation of building materials such as coloured plaster for use in building and 5 decorating applications.
It is well known to use plaster, concrete, mortar and grout, hereafter collectively termed "plaster", as a building material. Such building materials may be used in, for example, the coating of walls, the binding together of bricks or stones, the filling of 10 gaps between tiles or paving slabs, or the forming of pre-cast and moulded concrete products such as paving slabs, statues, ornaments, architectural faux stone and like products. Each plaster is commonly prepared for use just before it is to be used and, most commonly, the preparation involves the mixing of at least a dry powder such as plaster or cement with water. Other materials may be included in the mixture to 15 influence the physical properties of the mixed material once it has dried or set. Those other materials may be sand and / or other admixes. One of the possible admixes is a pigment or colourant which will result in a plaster that dries to a particular colour.
The use of pigments to colour plaster is well known. It is also well known that the 20 colour to which the plaster to which a pigment has been added will dry will depend on the type of pigment added and the quantity of the pigment added relative to the amount of plaster used. In this context the quantity of pigment can be measured by volume or by weight. The ratio of the plaster (and any other admixes) to pigment will be a major determinant of the final colour of the plaster. It is normally the case that 25 the quantity of pigment used is in the range of about 0 to 10% by weight or volume of the plaster to be coloured.
With coloured plaster, it is frequently required that either a specific colour of plaster is required or more than one mixture or batch of the plaster needs to be made with 30 each batch being the same colour. In either instance this is relatively easy if the batch or batches are prepared and mixed by a skilled person in conditions where the preparation of the materials to be mixed can include accurate weighing of the materials. Unfortunately, these conditions are frequently not available. This is especially true where the batch(es) are being prepared in the home as part of a do-it-
1
yourself (DIY) project or on a building site that is not sufficiently large to have a batching plant and associated technically trained personnel. This problem is addressed in W003/020661 (Bowman) which describes pre-mixing the plaster or cement powder with a pigment and then batching that dry mixture into bags. The 5 bags are then transported to where the plaster is needed and the contents of the bags mixed with water. This solution is useful only if the user of the plaster either wants the colour of plaster that has been pre-mixed, or he can persuade the party who does the pre-mixing to make a mixture of the colour that the user wants. In WO01/03899 (J^drzejewski) a method of making pigmented or dyed plasters is 10 disclosed where the pigment(s) is/are mixed with water and that pigmented water mixed with plaster or cement and possibly other materials. Such an approach requires, for colour consistency, an accurate measuring of the amount of water mixed with the plaster or cement. This can be particularly problematic if the plaster is to include an admix such as sand which is likely to include an un-measured and 15 variable quantity of moisture.
According to the present invention there are provided containers for pigments for use in the colouring of plaster, concrete and or grout in which the containers each contain a known quantity of pigment characterised in that the containers for 20 containing the pigment are formed of a flexible sheet material. These containers may be easily stored until opened and the contents placed in a device or apparatus for mixing plaster, concrete, mortar or grout. The plastics film is, in one preferred embodiment, polythene. Other plastics films may be employed,
25 In an alternative particularly preferred embodiment of the present invention, the containers for the pigment are formed from a substance that is water soluble. A preferred water soluble material is polyvinyl alcohol (PVOH). A particular advantage of use of a water soluble material is that the or each container of pigment may be placed in the mixture unopened and the water added to the mixture will dissolve the 30 container. This eliminates the possibility of spillage of the pigment. When a water soluble material is employed in the construction of a container according to the present invention, the flexible sheet material may be a blow moulded or extruded material which may flex or bend to some extent without undergoing permanent
2
deformation. Alternatively, and more preferably, the flexible sheet may be a thin pliant sheet.
In a preferred embodiment of the present invention a purchaser of pigment for use in 5 the colouring of plaster will purchase a quantity of pigment in which that quantity is contained in two or more containers, each container containing a known quantity of pigment. Each container may be marked with the quantity of pigment contained.
In a preferred embodiment, the containers may be of different sizes, for example 10 containing 10g, 20g, 50g, 100g, 500g, 1000g, 5000g, and 10000g of mixture, to allow a wide range of quantities of pigment to be accurately placed in the mixture. Different sized containers could be adopted and are within the scope of the present invention. If different sized containers of pigment are purchased, the purchaser will be able to combine the contents of the different sized containers to reach a range of 15 different total quantities of pigment.
The present invention further includes a kit for the production of a coloured plaster in which the kit is comprised of at least a colour chart and at least one container of pigment. The colour chart displays a range of colours and I or a range of shades of 20 a colour and, associated with each colour shown, an indication as to how to mix a plaster, concrete, mortar or grout to that colour. The indication may be the provision of a ratio of weights or volumes of pigment to plaster. The colour chart may contain a number of different indications to allow for the basic colours of plaster from different manufacturers and / or different admixes to the mixture, for example 25 different types of sand or sand from different origins.
A kit of this preferred embodiment of the present invention my further include a measuring means suitable for the measuring the quantity of plaster to be mixed with the pigment.
30
The measuring means is preferably a volumetric measuring means and includes a number of gradations that will allow varying quantities of plaster to be measured.
This will allow a wide range of ratios of plaster to pigment to be repeatedly produced. It is particularly beneficial to alter the ratio of plaster to pigment by adjusting the
3
quantity of plaster because as any given mixture will contain more plaster (by weight and volume) than pigment, any variation of the quantity of plaster included in a mixture due to inaccuracy of measurement is likely to have less effect on the plaster I pigment ratio than any variation in the quantity of pigment.
5
In an alternative embodiment of the present invention the distribution of pigment for use in the colouring of plaster comprises the provision of one or more colour guides that show possible colours and shades of colour of plaster by the distributor, the person to whom the pigment is to be distributed deciding which colour and shade of 10 plaster they want, and the provision by the distributor of one or more containers of pigment together with a direction as to how much plaster is to be mixed with one or more of the containers of pigment.
In a variation of this embodiment, the person to whom the pigment is to be 15 distributed may provide information as to the quantity of plaster with which the pigment is destined to be mixed, and the number of containers of pigment and / or the quantity of pigment in each or the containers, is adapted to suit that quantity of plaster.
20 According to the present invention there is further provided a method of preparation of coloured plaster comprising
(i) placing a known quantity of plaster in a mixing device;
(ii) placing a known quantity of pigment in the mixing device;
(iii) adding sufficient water to the mixing device to form a mixture of the desired 25 consistency;
(iv) mixing the plaster, pigment and water characterised in that the pigment is stored in one or more containers each of which contains a predetermined amount of pigment, and that the known quantity of pigment is an exact number of containers of pigment.
30
Step (iii) of the process of the present invention can occur either gradually or effectively all at the same time. It is preferred that if the mixing device is mixing while the ingredients of the plaster are being added to it, then at least some of the water of step (iii) is added to the mixing device before the pigment of step (ii) because the
pigment is most commonly a fine powder which may become airborne if mixed dry. This is particularly undesirable because it will reduce the quantity of pigment in the mix, thus affecting the colour, and may represent a health hazard to the person(s) operating the mixing device.
5
The mixing device can be any appropriate vessel or device given the absolute size of the intended mixture, for example a bowl or bucket for small quantities of mixture, or a concrete or cement mixer for larger quantities.
10 The method of the present invention my further include a user to identifying the colour of plaster that they desire on a colour card, and determining from data on that colour card the ratio of plaster to pigment to be used.
