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.
Repainting your house is a tricky business. Some rely on painting companies to do the job for you. Hiring the house painting service may also cost you.

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?
Main thing to consider when considering painting exterior of your home is; How long do I plan living in this house. If your answer is any longer than 1 year, you may reconsider from painting trim only to painting exterior completely. From a quick glance, fresh trim paint will work from an aesthetic point of view, but not even close from complete protection and value points. Therefore, being fugal painting, does not always mean painting just enough to get by, sometimes costing much more in the long run.
If a desired shade is not obtainable in custom-or ready-mixed paints, white paints may be tinted with colors-in-oil. To do this, mix the color-in-oil with a small amount of turpentine or mineral spirits and stir this into the white paint, a little at a time. If a blended color is desired, more than one color may be added, such as a chrome green and chrome yellow pigments to produce a lettuce green shade.
