Paint should not be applied to a concrete basement floor until the concrete has aged for at least a year. The floor should be dry when painted, the best time for application being during the winter or early spring (assuming there is some heating apparatus in the basement), when the humidity in the basement is low. In general, three coats of paint are required on an unpainted floor, and the first coat should be thin to secure good penetration. After the paint is dry, it should be protected with a coat of floor wax.
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.)
The reasoning here is simple. Every color in the visible spectrum can be assigned a number based on a luminosity scale (a scale from light to dark) from 0 to 9 where white is 0 and black is 9. Now suppose that the brown you are trying to cover has a score of 8, and the yellow paint you want to apply has a 4.
When it comes to choosing one's best clothing, accessories and makeup colors, many women are clueless. Some wear colors based on their intuition. Others follow the current fashion trends. Still others wear colors recommended by others. This leads to wrong choices, a less flattering look and wasted money. But, there is no need to guess. Color Me Beautiful, the authority in color, gives us a scientific process for finding the best colors.
There is still no standard labelling scheme for paint. The blue globe label, pioneered by B&Q, led to VOC reduction on the mass market and has been adopted by other brands, while the European Ecolabel, recognised in 15 EU member states, looks like a flower and appears on brands such as Earthborn. Germany also has a Blue Angel label and there is a green Nordic Swan as well. You will find more detailed information on most of the paint company's websites, as well as a wealth of practical and design advice.
However, for the more discerning, Dulux Kitchen & Bathroom paint can be mixed in any one of its 1,200 colours, and Farrow & Ball is launching Modern Emulsion. Designed to complement its original Estate Emulsion, the paint has a slightly higher sheen, is fully washable and available in the full colour range.
Practically every manufacturer has a "color system," a fat book of color chips with instructions for duplicating each chip. This is accomplished by intermixing cans of colored paint, by adding a concentrated color to a can of white or colored paint, or by adding concentrated color or colors to a can of neutral "base" paint. And for those who don't want any guesswork there's the Color Carousel that mixes the paints right in the store. Whatever the method, the result is a range of colors such as no amateur painter has seen.
