Masonry Walls and Ceilings. Interior masonry walls and ceilings above grade may, in general, be painted in much the same manner as plaster surfaces. Here again, it is necessary to allow adequate time for the masonry to dry before applying paint and, in addition, attention should be given to the preparation of the surface. When decorating a wall containing Portland cement (concrete, for example), it is essential to take precautions against the attack of alkali. For this purpose, alkali-resistant primers such as rubber-base paints may be used when oil paints are to follow.
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.
One precaution: You can't paint with it in cold weather. The chemical reaction that transforms the water solution into a durable finish will not take place if the temperature is below 50°. (Conventional oil paints don't stick well in cold weather, either.)

Complementary colors are opposites, and if you look at a color wheel, they are directly across from each other. While complementary ones may seem kind of mysterious to a novice, you just have to bring to mind Christmas to find a great example that is familiar to everyone, red and green.By simply making these colors a little paler, you can make this color palette work really well. Color tones are important, because rust and moss, while still being red and green, do not scream 'Christmas'. If your choice of tones is bold, you will create an eye popping design. However, it is common to get off course.
