Now let's proceed to analyzing the center of the composition. There is an optical center in the middle - you will notice that the center of the composition, the major element will never be placed there, otherwise the scene will look artificial. The center of the composition will always be the most striking element, and the rest will just serve to make it more expressive. The artist may use various means to achieve this effect - the color contrasts, light and shade effects, size of objects and distance between them. Secondary elements are depicted with less detail and vigor - they have to bring forward the center, not block it. Notice the way your eyes travel the painting - intuitively you will start at the center and will proceed to the rest of the elements to refine the story. Note: How to use an airless paint sprayer. I'm sure the guy at the rental store showed you how to use the airless (typically with his limited experience of actually painting a house), so hopefully I can offer you a couple new ideas on how to paint your home using an airless paint sprayer. When you first get the airless home, set it in the middle of the area that you would like to start painting. Typically the length of the hose is around 50'. Stretch out the hose prior to painting so that you don't have to worry about unraveling it while you are painting on a ladder. It is a good idea to have a 100' extension cord so that you can bring the airless anywhere you wish to paint without any restrictions. Tip: before you plug in the airless into the extension cord, MAKE SURE THE AIRLESS IS OFF! You don't want the airless to start pumping without paint! Now, when you go to set up the airless, before you turn it on, it's a good rule of thumb to have a second empty bucket next to your bucket of paint. I'll explain why in a second. Place both buckets side by side and place the intake hose (with the wire mesh filter end) into your 5 gallon bucket of paint while the primer hose (usually a lot smaller, about the size of a pencil'ish) is placed in the empty bucket of paint. Before you turn on the machine make sure that the airless is set to prime the machine first. There is a primer valve that you can rotate between prime and paint. A good way to see if the valve is set to prime or paint is to try this little test prior to turning the machine on. While turning the valve clockwise a couple times you will notice that the valve handle will separate from the machine in one position (leaving a slight crack between the valve and machine) while the other position the valve is close to the machine. The position in which the valve is separated from the machine is considered the primer position. Do this multiple times to see what I'm talking about. Don't worry if you keep on spinning the valve, you can spin it a million times in one direction and it won't hurt it. Inside the house is where acrylic shines. It dries faster than other types, and it keeps its color better, without yellowing. One disadvantage: It costs more.
Composition Wallboard. Composition wallboard usually presents no particular painting difficulties if the ordinary precautions are observed, such as making certain that the surface is dry and free from grease and oil. The painting procedure for wallboard is the same as for plaster; it requires a priming and sealing coat followed by whatever finishes coats are desired, or may be given one-coat flat or resin-emulsion type paint. 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! EXTERIOR PAINTING. In buying paints that you are going to use for your exterior house, you have to pick a brand that has essential characteristics: hiding power, color retention, chalk-resistance, and blister resistance. Following a European directive, the British paint industry has reduced VOCs in two stages, the second of which came into force in January last year.
