These days, manufacturers have created a variety of exterior painting products for an assortment of projects and painting problems. Whether your painting concrete block or need a protective coating for raw wood you can be assured a paint manufacturer somewhere more than likely makes it, and you can easily find a Denver painting contractor to apply it.
Below you will find a list of exterior painting products followed by information regarding the type of paint, solvent, coating or filler.
Oil Based Paint
Oil Based Paint contains pigments usually suspended in oil (normally linseed oil), a drier, and mineral spirits or some other type of thinner. The oil serves as the binder for the color pigments, the drier controls drying time and the thinner controls the flowing qualities of the paint. As the thinner evaporates, the mixture of color pigments and oil gradually dries to an elastic skin. As the oxygen is absorbed from the air by the oil (or curing), the curing action bonds a tough paint film to the surface. Oil paints are used inside and outside and are regarded as the traditional house paint.
Varnish consists of a solution of resins in a drying oil. Varnish contains little or no pigment. It dries and hardens by evaporation of the volatile solvents, oxidation of the oil, or both.
Varnish is recommended for both outdoor and indoor applications where a hard, glossy finish that is impervious to moisture is desired. For a satin finish, the gloss varnish surface can be rubbed down with steel wool, or a satin varnish can be used. As a floor finish, varnish provides a hard, durable film that will not greatly alter the tone of the wood.
Enamel is a varnish with pigments added. Enamel has the same basic durability and toughness of a good varnish. It produces an easy-to-clean surface, and in the proper formulation, it can be used for interior and exterior applications. For the highest quality interior work, an undercoat is required.
Consists of a dispersion of fine particles of synthetic resin and pigment and water. Latex paints are quick drying, low on odor, and thinned with water. They permit the repainting and decorating of a room within a day. Because latex paints set quickly, tools, equipment, and splattered areas should be cleaned properly with warm, soapy water.
No special primer is required for interior applications except over bare metal or wood, or over highly alkalined surfaces. Spot priming with shellac should be avoided because shiny spots will bleed through the latex film.
Exterior latex house paint can be applied directly to old painted surfaces. On new wood, it should be applied over a primer. For other surfaces, follow specific label directions.
The term “Water-Reducible Paints” has come into wider use in the paint business within the past few years. These products are also called water-based or water-borne paints. They include the well-known latex products, as well as products based on new synthetic polymers. While both groups employ water as the reducing agent, the chemistry of each is different.
For example, most latex coatings dry by solvent evaporation or coalescence. The new synthetic polymeric paints dry by a combination of solvent evaporation and chemical cross-linking.
Chemical cross-linking frequently requires the blending of two materials (these products are called two-component coatings) and a digestion time before the coating can be applied. The blending of specific materials results in chemical cross-linking and outstanding performance features, such as mar resistance, scratch resistance, washability, and stain resistance.
Alkyd finishes are produced in four sheens: flat, semi-gloss, low-luster, and high-gloss.
Flat finishes have a velvety texture and are used to produce a rich, softly reflective surface. Alkyd flats can often be applied to painted walls and ceilings, metal, fully cured plaster, wall board, and wood work without a primer. When required, the primer should be a similar material. For high alkaline surfaces, an alkali-resistant primer should be used.
Semi-gloss or low-luster types add just enough sheen to wood work and trim for contrast with flat finish wall surfaces. Each offers great resistance to wear and washing. Low-luster enamels are preferred in such areas as kitchens, bathrooms, nurserys, and school rooms.
Alkyd high-gloss enamels are often used for even greater surfacability and washability.
