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. Composition Wallboard. Composition wallboard usually presents no particular painting difficulties if the ordinary precautions are observed, such as making certain that the surface is dry and free from grease and oil. The painting procedure for wallboard is the same as for plaster; it requires a priming and sealing coat followed by whatever finishes coats are desired, or may be given one-coat flat or resin-emulsion type paint. One precaution: You can't paint with it in cold weather. The chemical reaction that transforms the water solution into a durable finish will not take place if the temperature is below 50°. (Conventional oil paints don't stick well in cold weather, either.)
Before you start painting, it is a good idea to keep an eye on the weather for rain or snow. You don't want to start painting only to stop abruptly because of the weather. Proper rolling technique: When rolling paint on the wall, get the roller skin evenly loaded with paint and make a V,N or M pattern on the wall, this is to spread the paint across the entire section you will be rolling, then roll back across the section and even out the paint. To properly "lay off" each section, make a final pass of the section applying light pressure to the roller frame arm end of the roller skin and bringing the nap mark (mark created on the pressure applied side of roller skin) across from the beginning of the section to the end of the section, and just repeat all the way down the wall.The V,N or M pattern, will be determine by how far the paint will spread, a V is for less spreading paint and M is for farther spreading paints. Do not "dry roll", which means trying to roll to much of a section at once with very little paint on the roller. Just as important, do not apply to much, if you find you are applying to much, increase the size of the section you are painting i.e. from a V pattern to an N or a N pattern to a M. Always use a sanding block for flat surfaces. Just your hand behind a thin piece of sand paper can leave grooves and low spots. It's also easier on your hands. For inside curves try wrapping the sand paper around a short section of garden or heater hose. This will help approximate the concave curve and help stay away from sanding through hard edges. On hard edges, like the top ridge of a fender or leading edge of a hood, you need to do this by hand. A sanding block will quickly dig right through the paint on a hard edge and take you down to bare metal. This means primer and more sanding. Painting in oil has long been a mysterious process the public has believed was relegated to the few and the eccentric. Artists and their lives have always been an unusual breed, but painting a large body of original oil paintings has also been a sure-fire way to drive oneself into immortality. The paintings will always be there, traveling through history, with your name on it! So by this definition it's definitely a noble profession. Think Dali, van Gogh, Picasso, Rembrandt and da Vinci. Each enjoys a lofty reputation for what others might consider crafts. And their reputations only grow bigger over time. What other profession offers that possibility? So who got the last laugh? Well, van Gogh did, of course. He's forever immortalized as one of the greatest humans to have ever lived. Not bad for someone who never made a dime in his own lifetime. But in the age of the Internet and the worldwide marketplace, artists don't have to starve anymore. I'm not starving, and I'm making money doing what I love. I can also work anywhere, whether I'm on vacation or traveling to exotic locales. I love that the most about it. I can do whatever I want and wherever I want, and post a painting for sale from Ibiza, Paris, London.... or Omaha. I wouldn't trade with anyone. And you won't either if you work at it and treat as a way to offer beauty to the world and get paid for it!
