Primer paints may be oil- or water-based and are used to seal unpainted surfaces to prevent covering coats of paint soaking in. The appropriate type of primer should be used for the surface being painted - wood, metal, plaster or tiles. There are some 'all purpose primers' available which are designed for two or more of these surfaces. Repainting your house is a tricky business. Some rely on painting companies to do the job for you. Hiring the house painting service may also cost you. But if you are planning to paint it yourself, you might want to consider the basics; and consider the time and effort you will put on painting your house. A good interior paint job is often 50% preparation and 50% painting. Do not rush in preparing the surfaces in your eagerness to get at the brush or roller. If you do not prepare the surfaces properly, you'll be back with the paint brush or roller in a few months.
Materials and their application, every paint manufacturers paint will vary. If you are freshening up old walls and painting back to the existing color, the product doesn't have to be high end or have good coverage. If you need to paint a dark color over light color or light color over dark, you may want to consider purchasing a top quality paint to avoid multiple coats. I suggest Valspar, Pittsburgh or Benjamin Moore top of the line wall paint. These brands work well for straight out of the bucket use and are application friendly. Sherwin Williams is not my first choice because the coverage is poor and you will have to apply multiple coats but, it does apply, fluently. If you find a product does not apply well, maybe it is to heavy and/or sagging on the wall, you may need to thin the paint with a little water, this will reduce the coverage but make the paint flow better and lay down nicer on the surface. I do recommend latex paints for all applications, these days a good high end latex is as good as oil paint and your tools clean up much easier, it will also be less harsh on the respiratory system. The only situation I recommend oil paint, is as a primer/stain blocker over stains that "bleed" through the paint. You can get a stain blocking oil primer in a convenient spray can and spot prime any trouble areas before painting and in the case you need to prime all of the wall due to smoke or water damage, I recommend getting it in gallons and rolling it on where the stains are present. Don't forget proper ventilation and/or a respirator when using the oil based primers! Cement-water paints are best suited for application to basement walls which are damp as a result of leakage or condensation. To apply these paints, the same procedure should be followed as is described here for painting exterior masonry walls. Malabar and Designers Guild offer some striking brights while the new Shades of Sanderson comprises 120 colours tailored to Sanderson's collections. If you are aiming for a more subtle backdrop that will flow through several rooms, it's wise to stick to neutral shades. Kevin McCloud's Elements of Colour for Fired Earth works especially well with our cool, northern light. There are two bases of paint for your house: solvent-based (oil or alkyd) and water-based (latex). Oil-based paints dry slow - usually taking up to 24 hours. The best clean up for an oil-based paint is turpentine or paint thinner. Latex paints' advantage is that it dries relatively fast, but it is not desirable in hot weather or direct sunshine. The best clean up for latex paints requires just soap and water. So if you are painting the inside of your house, it is recommended to use water-based paints, while solvent-based paints are suggested for painting the exterior of your house.
