Abstract
A texturing material suitable for building surfaces comprises a filler, for example a mineral filler such as whiting, together with pre-gelatinised cross-linked starch and gelatin. Preferably, the starch is in an amount from 0.2% to 5% by weight of the material, and the gelatin is in an amount of from 1.9% to 10% by weight. The material may also contain other binders such as cellulose ethers, and colourants, preservatives and wetting agents. Such texturing materials, after admixture of water, have good water retention, slip and pseudoplasticity properties.
Description
SPECIFICATION
Texturing material
The invention relates to texturing materials for use on the surfaces of building structures.
Texturing materials consist basically of a filler and an organic binder, and are required to have the following properties after admixture of water: water retention; slip, to facilitate spreading; and pseudoplasticity in order that it does not slump or reflow after application and before drying. In the past, these properties have been imparted to such materials by the addition of asbestos. However, in view of concern about health risks associated with asbestos, a suitable alternative has been desired.
Various additives have been proposed for this purpose, such as cellulose ethers and starches, but all have provided materials which have been deficient in at least one of the desirable properties noted above.
US 4 287 103 of Georgia-Pacific Corporation discloses a joint filling material comprising a gelatinised starch and a filler, with a synthetic binder such as an emulsion of ethylene vinyl acetate copolymer. This material, whilst suitable for use as a filling material, is found to be quite unsuitable for texturing purposes.
It has now been found that these desirable properties can be achieved by incorporating in the material the combination of a pre-gelatinised cross-linked starch and a gelatin binder. Other binders such as cellulose ethers may be included, and additives such as colourants, preservatives and wetting agents may be used.
According to the invention there is provided a texturing material, for application to building or other surfaces after admixture of water, comprising a filler, a pre-gelatinised cross-linked starch, and gelatin.
Preferably, the pre-gelatinised cross-linked starch is added in an amount of from 0.2% to 5% by weight of material, depending on the type of starch used and the degree of cross-linking. The gelatine is preferably added in an amount of from 1.9% to 10% by weight of the material, and particularly preferably in an amount of from 2.7% to 4% by weight.
The following are examples of texturing compositions according to the invention. The compositions are to be mixed with water before use, in a conventional manner.

The gelatine used in examples 1 to 7 has a gel strength of 120 bloomgrammes and viscosity of 39.5 millipoise; that used in examples 8 and 9 a gel strength of 71 bloomgrammes and a viscosity of 29.5 millipoise; that used in examples 10 and 11 a gel strength of 90 bloomgrammes and a viscosity of 33.5 millipoise; that used in examples 12 and 13 a gel strength of 1 55 bloomgrammes and a viscosity of 59 millipoise; and that used in examples 14 and 1 5 a gel strength of 1 95 bloomgrammes and a viscosity of 71 millipoise. Gel strength measurements were carried out on a Bloom gelometer at 1 00C, and viscosities were measured at 600 C.
The calcium sulphate hemihydrate used in the examples may be replaced by calcium sulphate dihydrate, with no effect on the properties of the texturing material. The whiting may be replaced by other carbonate fillers. For more rapid wetting out when the above materials are mixed with water, a powder wetting agent such as tripolyphosphate or sodium hexametaphosphate (Calgon) may be added.
Materials according to the invention are particularly suitable for texturing applications, but may also be used for jointing and filling purposes.
