Abstract

The surface treatment material comprises a settable synthetic resin and particulate components. The synthetic resin is preferably a polyester resin containing styrene in an amount of 65% v/v. The polyester may be based on glycerol and a dibasic acid, and the resin may include a cement bonder. To this may be added the following, preferably in the order stated: hydroquinone, dimethyl aniline, maleic anhydride and benzoyl peroxide. In treating a surface such as roof tiles, a mixture of the settable synthetic resin and particulate components is applied to the surface, and the resin is set. Before setting, a layer of fragmented matter is adhered to the surface of the coating; preferably, this matter is broken and/or crushed slates.

Description

"Surface Treatment" The invention particularly relates to a surface treatment material and method, especially for use on roofing tiles.
Roof replacement may be required owing to the breakdown and loss over a number of years of the factory-applied slurry that initially coated and weather-proofed the individual roofing tiles. Roof replacement may be costly and inconvenient.
According to the present invention there is provided surface treatment material comprising a settable synthetic resin and particulate components.
The resin may be a polyester resin including styrene; preferably, the styrene forms 65% (V/v) of the material.
The resin may have a base of glycerol and dibasic acid.
Preferably, the resin includes modifying acids, such as isophthalic acid, phthalic acid or adipic acid, which increase the toughness of the coating.
Preferably, the resin includes wax and is preaccelerated.
The material may include inhibitor; said inhibitor may be hydroquinone at, preferably at 0.01% (V/v), to prevent too rapid polymerisation and increase the thixotropic properties of the material.
Preferably, the material also includes a cement bonder, to adhere the mixture firmly to its substrate which may be cement or concrete.
One particulate component may be a weather-proofing material; the material may be dimethyl aniline, preferably added at 0.5% (V/v).
There may be included a component to control the flexibility of the settable resin; this component may be maleic anhydride, preferably at 0.5% (V/v).
Preferably, the material also includes an accelerator; this may be benzoyl peroxide, preferably at 1.0% (V/v); the time and quantity of the addition of the accelerator may allow tailoring of the material to suit the weather and working conditions.
The particulate matter may include a colourant to colour the material throughout; the colourant may be added with the dimethyl aniline when making the material.
Preferably, the material includes fragmented matter in the form of fragmented stone.
Further according to the present invention there is provided a method of treating a surface, wherein a mixture of a settable synthetic resin and particulate components is applied to the surface, and the resin is set.
Preferably, water is extracted from the resin before its mixing with the particulate components.
Preferably, air inhibition is eliminated from the resin before mixing with the particulate components.
The mixture may be applied by brushing or by spraying; the material may form a layer of 3 to 4 mm thickness.
Preferably, if spraying is utilised, the surface sub-divided into discrete units and the areas between said parts are masked prior to application of the mixture.
Before setting, a layer of fragmented matter is adhered to the surface of the coating; preferably, this matter is broken and/or crushed slates which in appearance conform with the building laws and conservation policy.
Preferably, the synthetic resin, the inhibitor and cement bonder are mixed together before the addition of any further components.
Preferably the following components are mixed with the resin in the following order: weather-proofing material; the component to control flexibilty of the resin; the accelerator.
An embodiment of the invention will now be described by way of illustration with reference to the accompanying Example: Example The following components are mixed together to form a resin base, water having been extracted from the material and air inhibition eliminated: Synthetic resin (polyester resin, preaccelerated, with added wax, preferably of silicone, and with a high proportion of styrene such that the styrene comprises 65% of the application) (As supplied by BIP Chemicals Limited) Modifying acids (e.g. iso-phthalic acid, phthalic acid, adipic acid) Dibasic and glycerol acid base Cement bonder To this is added the following, preferably in the order and proportions stated: Hydroquinone 0.01% Dimethyl aniline 0.5% (with colourant e.g.
red, green, brown) Maleic anhydride 0.58 Benzoyl peroxide 1.0% The ingredients are thoroughly mixed and, before use, vigorously stirred to render the thixotropic material liquid and suitable for application with a brush.
The surface, for example roofing tiles, to which the application is to be applied is first cleaned with a stiff brush to remove loose matter and rinsed with a solution of household bleach; when dust-free, a layer of application about 3 to 4 mm in thickness is brushed over each tile. The application may be sprayed on over a number of tiles simultaneously but dividers must first be placed between the tiles to prevent complete sealing of the roof and its consequent inability to breathe. However, the ease of the application with its ready thixotropicity and rapid drying allows effective coating by the simplest of means and spraying is largely unnecessary.
Before the coating is fully set (after about 10 to 15 minutes in general), crushed slates, of granular size 20/36 and 8/24, are scattered densely over its surface and a small roller used to press and firmly adhere the stones as a surface layer of 15 to 50 mm thickness. When fully set, surplus slate is brushed off with a soft household brush.
The slates, or other crushed or fragmented stone, textures and colours the tiles in agreement with local laws and conservation policy. The colourant, since added with the dimethyl aniline, is therefore apparent throughout the entire coating; in the event of chipping or loss of the layer of crushed slates, the colour remains constant in the damaged portion. The dimethyl aniline weather-proofs the coating and the maleic anhydride adds toughness and flexibility to the coating to help it resist cracking by expansion and/or contraction. The rapidity of drying is achieved by adding benzoyl peroxide, in the preferred quantity of 0.5% but this may be varied to suit the climatic conditions.
The glycerol and acid impart amongst other qualities flame resistance, and the cement bonder increases the coating's adherence to the treated surface. The hydroquinone is an inhibitor to polymerisation and the water extraction from the resin base improves the quality and durability of the eventual coating.
The invention is not only of use in restoring old roofs where the tiles have lost their protective factory-applied slurry but may also be of use for texturing and colouring new tiles in line with local conditions, or decorating and/or protecting other exposed surfaces.
Modifications and improvements may be incorporated without departing from the scope of the invention.
