When spraying your house, it is a good rule of thumb to spray in the direction of the grain of the material. So if you have siding that runs horizontal, you want to spray in a horizontal style. Also, when you go to spray, the gun should be approximately 12" from the material that you are spraying. Do not pull the handle to spray with your hand still. This will spray a lot of paint in one spot causing it to drip. So have your hand moving when you go to depress the handle. This will give you an even look to your paint.
Rubber-base paints, which dry to a hard semi-gloss finish, may be used on concrete floors below grade, providing the floor is not continually damp from seepage and condensation.
Years ago, paint was paint. One kind looked, smelled, was applied and eventually dried much like another. Things are different now. Besides oil paints, you can choose from a new set of paints. It'll pay you to know about them. • There are water paints you can use outside. (You clean your brushes under the faucet and use the garden hose to get spatters off the shrubbery.) • There are finishes so tough they withstand even attacks from the neighbors' children. • There are paints that dry so fast you start the second coat as soon as you finish putting on the first. • There are colors in glittering confusion.
Plaster. New dry plaster in good condition, which is to be finished with a paint other than water paint, should be given a coat of primer-sealer and allowed to dry thoroughly before being inspected for uniformity of appearance. Variations in gloss and color differences in the case of tinted primers indicate whether or not the whole surface has been completely sealed. If not, a second coat of primer-sealer should be applied. If only a few "suction spots" are apparent, a second coat over these areas may be sufficient.
First consider the size of the painting. The more impressive the subject, the higher the emotions it appeals to, the bigger it is. Religious, mythological paintings are often huge - their massive energy makes you shiver. It is pretty understandable with figurative paintings like Rafael's "The Sistine Madonna", and more subtle with color field paintings of Mark Rothko. People are often overwhelmed with religious tremor in the presence of his artwork, and the size factors in. Also, the subject often calls for larger canvases - battle scenes need space and cannot be fitted into a smaller painting, while some subjects will get lost unless depicted in a smaller size.
Today, it is increasingly easy to source ecologically sound paints, as most specialist ranges, such as Ecos, Earthborn, Georgina Barrow and Auro are available via mail order. There is a wealth of colour options in these pre-mixed ranges that include lush shades and muted palettes, reflecting their natural ingredients. Ecos continues to lead the field. It has recently developed Atmosphere Purifying Paint, which absorbs and neutralises volatile chemicals, solvents and VOCs from the atmosphere in a home.
Alkyd is an old interior paint made newly popular by a change in solvent - a super-refined petroleum chemical that has almost no odor. It is not a water paint. You thin it and clean brushes with mineral spirits or turpentine, or, if you want to retain the odorless feature, with the new odorless solvent. (Ask the paint-store man for just that, odorless solvent).
