You scuff up existing paint for two reasons. First, you want to get rid of any oil, grease or dirt trapped in the top layer of paint. This is the stuff that cleaners and degreasers can't get off. The second reason to scuff is to set up a physical bond for the new primer and paint to adhere to. You want to give the old paint some tooth so the new sticks better. Now here comes the fun part doors and wood work. This is where most people opt to use latex which is a huge mistake. Your home is your biggest investment don't cut corners on it's aesthetics. You want the finish on your woodwork to stand out from the walls especially if you have crown moulding or waynes coating. Don't be fooled by water based products that claim to give the look and finish of oil. It's just good marketing preying on people's fears of painting with oil. Don't believe the hype as those samples they show you have 3 or 4 coats that have been professionally sprayed in a dust free environment. You will not get the same results I can promise you that. You have a choice of semi-gloss or gloss finish. I prefer gloss because to me it gives you a bit more durability and shine. Either one will be fine for your project. Now let's get started. Proper brush technique: When "cutting in" with a paint brush you should dip the brush in paint and tap the sides of the bucket on each side of the brush, leaving a good amount on the brush so you are able to minimize the times you will need to dip/load the brush. Next, take the brush and make a one foot to two foot line down the wall about an inch or two away from the trim or surface you are going to paint up next to, this is much like taking a knife full of butter and spreading it across an entire slice of bread. After, spreading the paint over the section, go back and even the paint out evenly across the section and cut up next to the trim with the brush. You want to paint up next to the trim or surfaced to be cut-in with the paint brush after you have released most of the paint on the wall, it is easier to cut in with the tips of the brush exposed and not loaded with a lot of paint.
SECONDARY COLORS. When you mix two primary colors together, you get a secondary color. The secondary colors are orange, green and violet. Orange is made by mixing red with yellow. Green is made by mixing blue and yellow. Violet is made my mixing blue with red. Satin or silk - Water-based vinyl or acrylic paint for walls in high-wear areas, such as hallways and kitchens. A satin finish will be slightly shinier than silk. Orange color is a color of warmth, bliss, heat, but at the same time it is a color of the glitter of the setting sun. It is always pleasing to the eye and contributes to good mood. Almost always orange color has a positive beneficial influence. White - is the concentration of all colors from the physical standpoint, since it is the white light that decomposes into all the colors of the spectrum when refracted in the facets of the glass pyramid. White color goes well with all the other colors, it is universal and brings in the element of elegance.
