Primer paints may be oil- or water-based and are used to seal unpainted surfaces to prevent covering coats of paint soaking in. The appropriate type of primer should be used for the surface being painted - wood, metal, plaster or tiles. There are some 'all purpose primers' available which are designed for two or more of these surfaces. Inside the house is where acrylic shines. It dries faster than other types, and it keeps its color better, without yellowing. One disadvantage: It costs more. Store your leftover paint in plastic Rubbermaid beverage jugs or other plastic seal-able containers. Paint left in the can always gets funny after time. Either the can isn't properly sealed of it gets exposed to extreme heat or cold. I like to store my paint inside where the temperature is controlled.
The purpose of this article is to take the mystery out of the process of painting. This article is only written to get you started. I'll write more detailed techniques later. But this article will set you on your way to experimenting and having fun with paint. Ultimately it's like anything in this world. Before you have the knowledge, it's complicated. But once you have it, it's easy! Knowledge is power, and this phenomenon definitely applies to painting. The technical aspects are the easy part. Anyone can do it. You ultimately could be as capable as Monet with practice. We humans can do whatever we decide to do! Deciding WHAT to paint is the hard part. It takes discipline and a singularly focused desire to create one painting after another. For whatever reason, I loved it the minute I started. And I never looked back. I love it today as much as I did over 16 years ago. I never have "writer's block" either as to what to paint. I just paint from my experiences in life. So don't think too hard on it. Paint that apple sitting on the table, or paint the tree in your own back yard, paint your girlfriend in an unusual way. But paint something that means something to you, that's all that matters. Make it funky, make it interesting. If it's abstract, remember that abstract art has long been the most desirable. It's an expression of the individual, make it unique. For those who want realism, take a picture. What's amazing is that once you do it, you realize it's the ultimate escape into happiness. Suddenly you forget your problems for that period of time. You have control, and no one can take it away from you once you are skilled at painting. The process is addicting. But like anything, you must START! And once you do, look out....you'll be hooked. Knock down texture is basically a orange peel that is sprayed on and allowed to "set-up" for a minute or two then gently "knocked down" by running a 6" drywall knife over it, "knocking down" the surface of the texture. Although knock down is a flattened version of orange peel, I suggest you do not use a spray can of orange peel, the knock down comes in its own spray can and the results are much better, again experiment before spraying it on the wall. However, If ever you apply any of the textures to the wall and are not satisfied with the results, wash the texture off immediately before it dries, then allow the wall to dry and try it again. Once you have the texture applied to your liking and you have allowed it to dry, you may want to paint the patches a couple of time before painting the entire wall, especially for walls where the paint to be applied will have some sheen. Multiple coats on these areas will make them blend in, unnoticeable, with the rest of the wall. You will know if the patches need more coats of paint, because the patch/texture will have absorbed the paint causing the spot to look duller than the rest of the existing wall. 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. Treat yourself to a good lunch and forget the diet. It is amazing what some pizza or a good burger will do for the afternoon painting push.
