Hiding power comes from the paint's pigment and is affected by the manner and thickness of the application. Color retention is the ability to maintain its original color during exposure to sunlight, etc. Chalking resistance prevents the white chalky powder from forming on the surface and lightening the color of the paint. Chalking occur over a period of time. Blister resistance keeps excessive moisture from coming through the substrate and affecting the paint layer. Tip: if paint is applied over a damp or wet surface, blistering is imminent. 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.) Special Surfaces. WHITEWASH. Whitewashes and lime paints must be thin when applied. In fact, best results will be obtained if the application is so thin that the surface to which it is applied may easily be seen through the film while it is wet. The coating will dry opaque, but two thin Coats will give better results than one thick coat.
First consider the size of the painting. The more impressive the subject, the higher the emotions it appeals to, the bigger it is. Religious, mythological paintings are often huge - their massive energy makes you shiver. It is pretty understandable with figurative paintings like Rafael's "The Sistine Madonna", and more subtle with color field paintings of Mark Rothko. People are often overwhelmed with religious tremor in the presence of his artwork, and the size factors in. Also, the subject often calls for larger canvases - battle scenes need space and cannot be fitted into a smaller painting, while some subjects will get lost unless depicted in a smaller size. Another idea keeping Paint Brush moist until the next paint coat is applied (but not leaving for extended periods) is leaving Brush in container, wrapping top with plastic, sticking handle out the top, and taping around the can. This resembles the Maxwell House Coffee Container mentioned earlier. If plastic and masking tape is still not available, and time between coats is not very long, take that sopping wet rag, draping over the top of paint bucket with Paint Brush still in it. This technique works best when using Latex waterborne paints. Did you know when you walk in a room others size you up in just seven seconds? And, believe it or not, that's before you have said anything. Color is a big part of what makes up your appearance. The right colors will make you look younger, more confident, taller, healthier and bring out your natural beauty. The wrong colors will make you look tired, frazzled and can add extra years. Some acrylics are also recommended for exteriors (over the same kinds of materials as vinyl paints). Here it has a big advantage - you don't have to pick your painting weather so carefully. It can be applied on humid days and in cold seasons, so long as the temperature is a few degrees above freezing.
