Most of us look to save where we can, especially in this day and economic conditions. House painting is no different, when it comes to saving money. A home exterior weathers from harsh elements of heat, cold, sun, and snow, and exterior paint ages over time needing repainting. Exterior trim, being that of solid wood is normally the first to show signs of painting maintenance. Many times a homeowner happens to call, asking for only painting the trim. Trim paint jobs sound good at first, but have some underlying thoughts may have not been considered. Below are things to consider when considering painting trim only.
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.)
Also, when checking the paint, be realistic and don't ignore areas just for the sake of convenience. It will cost you more in time and money later. Typically if one area of the paint is cracked or peeling, then the paint on the entire car is suspect. Maybe the rest of the car just hasn't quite reached that point of decay, but it will shortly. So if you only fix areas that look bad, you'll likely find that you wasted a paint job when the other areas start to crack or peel in a year or two.
"Boxing" is a good method of mixing paints. Since paint is a mixture of solids and liquids, it is important that it be mixed thoroughly before using. To do this, the greater portion of the liquid contents of the can should be poured in a clean bucket somewhat larger than the paint can. Then, with a stiff paddle, the settled pigment in the original container should be loosened and any lumps broken up. After this, mix the material in the container thoroughly, using a figure 8 motion, and follow with a lifting and beating motion. Continue stirring the mixture vigorously while slowly adding the liquid that was previously poured off the top. Complete the mixing by pouring the paint back and forth from one container to the other several times until the entire amount is of uniform consistency.
Masonry paints come in a wide variety of finishes, from textured to ultra-smooth. Opt for a texture if you need to disguise fine surface cracks. If you favour traditional finishes, then consider limewash, which is available from specialists such as Francesca's Lime Wash. The beauty of this paint is that it will mellow and weather with time. However, do check with the supplier first to ensure that the surface is suitable for this finish.
The principal ingredient in whitewash is lime paste. A satisfactory paste can be made with hydrated lime, but better results are obtained by using quicklime paste that has been slaked with enough water to make it moderately stiff. The lime paste should be kept in a loosely covered container for at least several days. Eight gallons of stiff lime paste can be made by slaking 25 lbs. of quicklime in 10 gallons of water, or by soaking 50 lbs. of hydrated lime in 6 gallons of water. After soaking, the paste should be strained through a fine screen to remove lumps or foreign matter.
So what exactly makes a rose appear "red" or grass appear "green". In the green grass, you are only seeing green because the grass has pigments in it that absorb all colors of the solar spectrum except green. So green is the color that is reflected back to your eyes. The same holds true for the red rose, only the rose absorbs all colors of the spectrum besides red.
