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.
The paints may be applied by brush or spray; the small spray attachment for vacuum cleaners is very convenient, especially for painting radiators.
Special Surfaces. WHITEWASH. Whitewashes and lime paints must be thin when applied. In fact, best results will be obtained if the application is so thin that the surface to which it is applied may easily be seen through the film while it is wet. The coating will dry opaque, but two thin Coats will give better results than one thick coat.
Blue Dogs and the Legend of Loup Garou. In 1992, George Rodrigue, a Cajun artist from New Iberia, Louisiana, painted a series of paintings called The Blue Dog Pictures which were made popular by an advertising campaign done by Absolute Vodka. The blue dog has popped up in numerous other venues since then, but it wasn't created for commercial purposes. Rodrigue based his paintings on the Cajun legend of Loup Garou, the werewolf that is said to haunt the swamplands surrounding Acadiana and New Orleans. Parents teach their children morality lessons using the character and the commercial use of the blue dog has softened its image, but both Cajun and ancient American Indians still declare there's a factual basis for the story. Is there a werewolf in the bayou?
Take your time there is no rush. There is nothing wrong with having your project take a couple of weeks.
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.
A large whitewash brush is best for applying the wash. One should not attempt to brush out the coating, as in applying oil paint, but simply spread the whitewash on as evenly and quickly as possible.
