There are many different types of paint to choose from. Depending on the painting job, the right paint will make it easier for you to apply the paint and affect the longevity of the application as well. Learn about the various types of paint available in today’s market.
Type of Paint
Acoustic Paint was developed to be used on acoustic ceiling tiles, since it has little effect on the acoustic properties of the tile. It’s usually applied with sprayer, although a roller can also be used.
Oil-Based Paint is made of pigment suspended in a slow-drying oil, usually linseed oil. A solvent such as white spirit or turpentine can be added to make it more viscous, and the addition of varnish gives the dried paint a glossier look.
Acrylic paint is made of pigment suspended in an acrylic polymer emulsion. It’s a fast-drying paint that is water-resistant when it dries, even though it can be diluted with water. Because it expands and contracts with variations in heat, it holds very well on exteriors.
Latex paint is water-based. It can be used effectively on unprimed drywall, unpainted masonry, and surfaces previously painted with latex or flat oil-based paints, but it can’t be expected to hold well to high-gloss finishes, Because it is water-based, it will raise the grain on raw wood, cause bare iron or steel to ruse, and it might make wallpaper peel off the wall.
Primer is meant to adhere well, forming a binding layer on the surface that allows the finishing paint to adhere well. Primers are designed to have improved binding and filling properties with the surface material, either because of physical properties such as hygroscopy, porosity, and tackiness, or because of its chemistry (as in aluminum primer, for example).
Textured Paint is available in several varieties. Some is very thick and smooth so that it can be textured with special tools after it’s applied. Other types use granules to create their texture. Sand-like particles may be premixed with the paint or they the particles may have to be added and stirred in thoroughly to prepare the paint. Textured paints may be used to cover flawed surfaces or create a stucco-like finish.
Textured flat-finish latex paints are often used on bare drywall ceilings because they camouflage the seams and they don’t require a primer.
The biggest disadvantage of textured paint is that the texture increases the area of the surface, which will require 15 to 25 percent more paint when it needs to be repainted.
Eco-Paints (No-VOC or Low-VOC) are specially formulated to contain few or no volatile organic compounds (VOCs), which are gases that may have short- or long-term adverse effects on health. There are often high quantities of VOCs in the solvents used in traditional paints. Low-VOC and no-VOC paints feature low odour, excellent durability, and a washable finish, in addition to improving the quality of indoor air and reducing urban smog. Among types of low-VOC paint are:
Milk Paint is basically made of milk and lime. Pigments may be added for colour and borax may also be added as a preservative and to help dissolve the casein from the milk. Its biggest drawback is its short shelf life. It has to be used within a day (perhaps a little longer if refrigerated), because the milk will spoil. Milk paint has become more popular in recent years because of the green building movement. Many milk paints now use natural pigments and are considered “green” as well as being nontoxic.
