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. Hiding power comes from the paint's pigment and is affected by the manner and thickness of the application. Color retention is the ability to maintain its original color during exposure to sunlight, etc. Chalking resistance prevents the white chalky powder from forming on the surface and lightening the color of the paint. Chalking occur over a period of time. Blister resistance keeps excessive moisture from coming through the substrate and affecting the paint layer. Tip: if paint is applied over a damp or wet surface, blistering is imminent. Obviously, when mistakes like this occur paint companies have nothing to lose. Whenever people pick paint colors that they are unhappy with, the paint company does not have to refund the customers' money. In fact, no paint brand in the country will allow you to return paint once you have purchased it. Even better (for the paint company), since the customer is unhappy with the paint color they chose, they are probably just going to buy a whole new batch of paints!
Either edge of trim is painted with body color, and is where caulking is applied at most 90 degree angles. Painting trim only, cannot feasibly include caulking, as this fails and opens up over time. Most homes need new caulking when painting the exterior, and a close inspection can determine. The salt and alum should be dis-solved in 4 gallons of hot water, after which the molasses may be added to the mixture. The resulting clear solution is then added to the lime paste, stirred vigorously, and thinned with water to the desired consistency. This whitewash has a yellow tinge when first applied, but the color disappears in a few days leaving a white film. Have plenty of newspaper around. After you clean your brushes wrap them in a plastic bag. Now that you have primed the airless, make sure that there isn't a tip in the gun of the airless and bring it over to the empty bucket. Since there is typically cleaning solution in the hose leading to the gun it is a good idea to spray that out until you see thick paint coming out. Once you have thick paint coming out you may put your tip back in. Remember that the tip will have an arrow on one side of the handle that shows which direction it must be in, in order to spray.
