Abstract

A composition suitable for application to stonework or brickwork, comprises an aqueous carrier, an adhesive agent to facilitate adhesion of the composition to said stonework or brickwork and a pigment to impart a desired colour to the stonework or brickwork. The adhesive agent preferably comprises a styrene acrylic emulsion. The composition may further comprise a cellulosic thickener, a surfactant, a plasticiser, a matting agent, a pH control agent and/or a biocide. The composition imparts a weathered appearance to the stonework or brickwork, and is useful in applying to new brick- or stone-work which has replaced older brick- or stone-work.

Description

A COMPOSITION SUITABLE FOR APPLICATION TO STONEWORK OR BRICKWORK This invention relates to compositions which are suitable for application to stonework or brickwork. More particularly, this invention relates to such compositions which can be used to impart to the stonework or brickwork a weathered appearance. The term "weathered appearance" as used herein refers to the appearance of stonework or brickwork that has suffered weathering.
Where brick buildings have been standing for several years, the brickwork can often need considerable repair in places. Typically, this repair is carried out by replacing the old bricks with new bricks. This results in the problem that the old bricks will have a weathered appearance whereas the new bricks do not, which results in an overall appearance of the building that is aesthetically unappealing.
It is therefore an object of this invention to provide a composition which overcomes the above problem.
According to a first aspect of this invention there is provided a composition suitable for application to stonework or brickwork, said composition comprising an adhesive agent which may be in an amount of 18 to 40 percent by weight to allow the composition to adhere to the stonework or brickwork, and an amount of a desired pigment to impart a desired colour to the stonework or brickwork and an aqueous carrier making up the balance of the composition.
The amount of said adhesive agent is preferably in the range of 20 to 30 percent by weight and, more preferably 22 to 25 percent by weight of said composition.
This invention is particularly suitable for imparting a weathered appearance to stonework or brickwork. Thus, the composition has the advantage that it can be applied to new brickwork and stonework which has replaced older brickwork or stonework and thereby imparting to the new brickwork or stonework a weathered appearance to match the older adjacent brickwork or stonework.
The adhesive agent may comprise an emulstion, preferably an acrylic emulsion, and more preferably a styrene acrylic emulsion. The composition may further comprise a cellulosic thickener which may be present in an amount in the range of 0 to 1 percent by weight, preferably 0.2 to 0.7 percent by weight and more preferably 0.3 to 0.5 percent by weight.
The composition may further comprise a surfactant which may be present in an amount of 0 to 1.0 percent by weight, preferably 0.2 to 0.7 percent by weight and, more preferably 0.3 to 0.5 percent by weight. A plasticiser may be provided in the composition. The plasticiser may be added in an amount of 0 to 5 percent by weight preferably 0.8 to 3 percent by weight and, more preferably, 1 to 1.5 percent by weight.
The composition may contain a matting agent which may be added in an amount of 0 to 5 percent by weight, preferably 2.5 to 4.5 percent by weight and more preferably substantially 3 to 4 percent by weight.
Desirably, the composition comprises a pH control agent to maintain the pH of the composition at around 6.5 to 9.5 pH. The amount of pH control agent added to the composition will depend upon the relative amounts of the other ingredients but is typically about 0 to 1 percent by weight.
A biocide may be added to destroy plant organisms on the stonework or brickwork. The amount of biocide is typically about 0 to 2% by weight, preferably about 0.5 parts by weight.
According to a second aspect of this invention there is provided a composition suitable for application to stonework or brickwork, said composition comprising substantially 75 parts by weight of an aqueous carrier, substantially 25 parts by weight of a styrene acrylic emulsion, substantially 0.4 parts by weight of a cellulosic thickener, substantially 0.4 parts by weight of a surfactant, substantially 1.2 parts by weight of a plasticiser, and a desired amount of a chosen pigment to impart a desired colour to the stonework or brickwork.
The composition according to the second aspect of the invention may comprise one or more features of the composition according to the first aspect of the invention.
According to a third aspect of the invention there is provided a method of treating stonework or brickwork to impart a weathered appearance thereto, said method comprising applying to said stonework or brickwork a composition described above.
According to a fourth aspect of the invention there is provided the use of a composition as described above in the treatment of stonework or brickwork to impart thereto a weathered appearance.
This invention will now be described by way of example.
EXAMPLE A composition comprising the following ingredients was prepared by mixing the ingredients together.
INGREDIENT PARTS BY WEIGHT Water 75 Cellulosic Thickener 0.4 Surfactant 0.4 Matting agent 3.75 Plasticiser 1.25 pH control agent 0.1 Biocide 0.5 Styrene acrylic emulsion 25 The composition also contains a preselected amount of a pigment to impart a desired colour to stonework or brickwork.
The styrene acrylic emulsion and the cellulosic thickener acts as an adhesive agent to allow the composition to adhere to stonework or brickwork.
When prepared, the composition is applied to stonework or brickwork, for example a brick wall of a house. The composition can be applied by any suitable means such as by painting it on with a paintbrush.
When the composition was applied to new bricks in a brick wall the bricks took on a weathered appearance, that is the bricks to which the composition was applied took on the appearance of bricks which were several years old.
This invention is particularly advantageous when repairs are necessary to old brick walls. New bricks are used to repair the old walls and after they have been treated with the composition, the new bricks become substantially the same appearance as the older bricks in the wall.
