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.
The paints may be applied by brush or spray; the small spray attachment for vacuum cleaners is very convenient, especially for painting radiators.
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.
Selecting a Shop. You should always get quotes from at least 2-3 different shops near you. This will give you a chance to not only compare prices, but to also check out the quality of work each shop has done. Ask to see cars they've just painted. Look for orange peel or excessive overspray. Do they mostly do insurance work or do they paint entire cars also? What types of cars are they working on? A shop that sprays nothing but old beaters probably doesn't inspire as much confidence as one that does insurance work for the local Lexus or Mercedes dealer.
You can tell when the bucket of paint is getting low when the airless starts pumping really loud and doesn't stop. Simply tip the nearly empty bucket of paint, at an angle so that the mesh filter is covered and wait for the airless to catch up and stop pumping. Sometimes it's just easier to just to replace the bucket of paint with the new one and when that starts going down, pour the excess from the old bucket into the new one.
Types of Paint. Water-based paints are usually referred to as emulsions and were traditionally used only for interior walls and ceilings. But recently tremendous advances in paint technology mean that water-based formulas, especially the high-performing acrylics, are available for all surfaces, from woodwork to metal, and for interior and exterior use. The advantages of these paints over oil-based ones is that they are cleaner, have less odour and are more environmentally sound. Brushes can be rinsed clean with water.
Sadly, not only are people more attracted to the paint color wheels because of these colors, but beginners are more likely to find one of these bright, saturated colors most attractive and end up choosing one as their new paint color. Unfortunately, for most of the reasons discussed above, those colors look ridiculous painted on walls.
