Cold water paints of the casein type may be applied either directly to a plastered surface, or the surface may be first given a coat of primer-sealer to equalize uneven suction effects. The same is true of resin-emulsion paints, with the recommendations of the manufacturer of the product being given preference in case of doubt. Since resin-emulsion paints usually contain some oil in the binder, they should ordinarily be applied only to plaster which has dried thoroughly.
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!
When all of the spraying is complete, its time to remove all masking tape and paper and start touching up your entire home. This step is pretty time consuming because this is the final stage that really makes your home look good. The more time you spend here, the better your home will look.
A large whitewash brush is best for applying the wash. One should not attempt to brush out the coating, as in applying oil paint, but simply spread the whitewash on as evenly and quickly as possible.
Pick a brand you can trust Companies with their own high-street shops, such as Fired Earth and Farrow & Ball, and those that sell through the DIY giants are the most accessible. However, buying paint online is increasingly popular and can bring you a wider choice, especially if you live outside major towns and cities.
If you have large holes or cracks in a wall purchase a small can of vinyl repair paste. The reason I prefer it over regular wall Spackle is that after it dries it is much harder and sands easily. You can even use it for minor wood repair in a pinch.
COMPLIMENTARY COLORS. These are colors that are opposite from one another on the color wheel. Red and green, blue and orange, yellow and violet, are examples of complimentary colors. Complimentary colors are colors of extreme contrast. When used together in a painting, they can produce brilliant vibrant images.
