Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. These waterproof gypsum panels have many uses, such as, tile backer board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, interior wall and ceiling, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, preferably silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives. Preferably a pre-coated non-woven glass fiber mat is employed to provide the inorganic mineral fibers for the surface reinforcement.

The invention provides a set gypsum-containing product having increased resistance to permanent deformation and a method for preparing it comprising forming a mixture of a calcium sulfate material, water, and an appropriate amount of one or more enhancing materials chosen from condensed phosphoric acids, each of which comprises 2 or more phosphoric acid units; and salts or ions of condensed phosphates, each of which comprises 2 or more phosphate units. The mixture is then maintained under conditions sufficient for the calcium sulfate material to form a set gypsum material.

The multifunctional paint is based on a highly porous inorganic substance created by a reaction of at least two components. TiO2 nanoparticles are attached to the surface of this substance. The first component is a water insoluble calcium compound and the second component is a water soluble sulfate. The method of applying the multifunctional paint on the surface is that the first component containing the water suspension of the insoluble calcium compound is applied on the treated area first and subsequently a mixture of TiO2 nanoparticles suspended in the water solution of the second component is applied over the first layer. Another way is to apply a water suspension of the first component containing also TiO2 nanoparticles on the treated surface and then deposit the water solution of the second component on the layer. A mixture of all components can be also applied on the treated area at once.

摘要:
According to the invention, a metal salt and an oxygen source are applied to penetrate or impregnate a suitable substrate sequentially in effective amounts so as to react in contact with the substrate and produce a mineral compound fixed within the surface of the substrate. The inventive combination of a mutually compatible metal salt, oxygen source, and substrate brings about an in situ reaction, and modifies the substrate to bring about a lasting desired effect. The mineral compound that is produced according to the invention is linked to the substrate, is stable and long-lasting or permanent, and is immobilized or insolubilized in the substrate. The mineral compound is bound or contained within and on the surface of the substrate, so it may be said to be ingrained in the fibers or matrix of the substrate, or embedded within the substrate. The desired effect is preferably a color. A wide variety of metal salts may be used depending on the desired effect. The oxygen source is preferably a peroxide, and the substrate is preferably a cellulose product such as wood, cotton, or paper; leather; or masonry. The invention contemplates methods of treating substrates, treatment kits, and treated products. With wood products, the invention provides a water-based stain of low toxicity useful for soft woods.

摘要:
A composite tile is fabricated to resemble stamped concrete or interlocked brick arrangements. The composite tile may be produced in various shapes, sizes, surface designs and colours and can be applied to outdoor surfaces, for example, asphalt, concrete, or wood surfaces such as driveways, sidewalks, porches, balconies and decks. In one embodiment, a composite tile is provided that comprises a durable, polymer containing mineral layer; an adhesive backing; and a removable protective layer covering the adhesive backing. One method for making the composite tile comprises applying an adhesive backing to a durable, polymer containing mineral layer. A pattern and/or a variegated appearance may be produced either before or after the adhesive is applied by at least one of stamping a pattern onto the polymer containing mineral layer, casting/molding the polymer containing mineral layer in a mold such as a tray, varying the mineral appearance of the polymer containing mineral layer, and varying the pigmentation therein. The composite tile may, if necessary, be cut to an appropriate size/shape.
