Paints in powdered form require the addition of a liquid to prepare them for use. The manufacturer's directions as to the amount of oil, varnish, water, or other vehicle required should be followed.
Rubber-base paints, which dry to a hard semi-gloss finish, may be used on concrete floors below grade, providing the floor is not continually damp from seepage and condensation.
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.
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!
Water-thinned rubber-latex paint is already an old reliable, though it is only about 10 years old. It accounts for a big percentage of all paint sold and is still the most widely available of the easy-to-use finishes. One new type is a combination vinyl-rubber paint that is said to do a better job on interiors than either vinyl or rubber alone because it dries faster, lasts longer and has less sheen.
Painting ceiling does not require premium paint. You can use flat $15 to $20 ceiling paint. I use Sherwin Williams PRO-MAR 200. Painting ceiling requires a lot of physical work and plenty of drop cloths. If you are not up for the challenge or have very high ceilings contacted a professional will prove to be a smart move.
Ecological Paint. The "organic" paint brands, such as Ecos, which emerged in the late 1980s, heralded a new era of odourless paints, free of solvents and VOCs (volatile organic compounds) and paved the way for other companies' environmentally safe formulas. Following European legislation, the first stage in lowering the solvent content in paints and varnishes is set to come into force in 2007.
