HUE-VALUE-INTENSITY. Hue: Without getting too technical, and to put things into laymen's terms, hue is just another word for color. For instance, grass and leaves are two variations of a green hue. 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! Are the contours rough or concealed?
Once you figure out which position is prime and which position is spray, place the valve in the prime position and grab the primer hose. Point the primer hose in the empty bucket near the top and at an aproxx.45 degree angle from the side (the reason for this is that there is likely to be pressure still built up in the airless and when you first switch on the airless to prime it, paint will likely burst out of the primer hose and you don't want to have it go everywhere). Now turn the airless paint sprayer on and you will see that the airless is sucking up the new paint and pumping out the primer hose. At first you will typically see a cleaning solution come out followed by your paint. When you see your paint coming out switch over the primer valve to the other position and you will see the airless pumping paint into the main hose. So lets start with Warm and Cool. When thinking about Warm, think about a desert panorama of gold, brown and earth tones. When thinking about Cool think of colors in the artic such as gray, black, white or think of the deep blue sea such as deep blues, blue greens and turquoise. Everyone can wear just about any color, the difference is in the shade of the color. When thinking of clothing, makeup or accessories, visualize Cool as a color with a drop of silvery-blue. Visualize Warm as a color with a drop of gold. For example, if you put a drop of gold to a red sweater it becomes a Warm red, but if you put a drop of silvery blue it becomes a Cool red. Traditionally, the solvents or VOCs and other chemicals used to make paints easier to apply give off toxic fumes that seep into the atmosphere for years after application. Paints with reduced or no VOCs are healthier for decorators and the people whose homes are painted with them. Painting the exterior of your house requires a thorough estimation, visualization and preparation. When you have chosen your theme for your rooms and have bought the job materials you need.
