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.)
EXTERIOR PAINTING. In buying paints that you are going to use for your exterior house, you have to pick a brand that has essential characteristics: hiding power, color retention, chalk-resistance, and blister resistance.
HUE-VALUE-INTENSITY. Hue: Without getting too technical, and to put things into laymen's terms, hue is just another word for color. For instance, grass and leaves are two variations of a green hue.
Concrete Floors. Two general types of paints for concrete floors are varnish and rubber-base paint. Each has its limitations and the finish cannot be patched without the patched area showing through. Floor and deck enamel of the varnish type gives good service on concrete floors above grade where there is no moisture present.
White color symbolizes the purity, immaculateness, innocence, virtue, and joy. It always inspires, helps, fills you with faith. White means absolute freedom from obstacles and freedom for all possibilities.
The area covered by a gallon of whitewash depends upon the nature of the surface, but ordinarily a gallon will cover about 225 sq. ft. on wood, about 180 sq. ft. on brick, and about 270 sq. ft. on plaster. The formulas mentioned will make from 10 to 14 gallons of whitewash. If a smaller quantity is desired, the amount of each ingredient should be reduced proportionately.
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.
