In this section are some tips on techniques and tools that make it easier to paint your house than ever before - not the way the "pro" does, perhaps, but with much the same results. You can put it around a room and probably follow immediately with the finish coat. It can be applied with brush or roller. 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 reality is that the guys shooting paint, even at the cheapest shops, know how to do it. They spray a dozen cars a week and have plenty of practice laying down smooth, consistent coats of paint. They work quickly and efficiently because they have to or they don't make money. They don't really make their money on shooting paint. They profit from body work because it takes time and insurance work because it pays well. Visual perceptual skills: Visual perception develops through a child's interaction with his environment. When a child stretches his arm to reach a high branch, or climbs through a tunnel in an obstacle course, he is developing his spatial perception. Shape perception is developed by a child grasping and manipulating many different objects in play. When he cannot find the toy he wants and has to search for it in his toy-box, he is developing figure-ground perception. Now take a look at the form of the canvas - you might take it for granted, but it does influence the subconscious feeling you get when enjoying a piece of art. Round and oval canvases produce the impression of serenity and completeness, they are often picked for feminine, soft portraits, like Ingre's "Turkish bath". Rectangular paintings - vertical or horizontal - are more complicated. While widely used in landscapes, the horizontal format may serve to diminish the figure portrayed, impose or convey some limits, as you can see in Vrubel's "Demon". Vertical format ensures monumentality and steadiness. Most homes exterior trim is painted on the front only, more commonly called front-facing the trim. Sides of trim is normally painted with main body color. Few homes have trim painted on all 3 visible surfaces, called in the painting industry as 3-D'ed painting.
