Painting trim is normally done by roller and brush, not sprayed, so more manual labor is required painting trim, and most cases costing 60% of the total exterior painting job. The second part of preparation is surface prep, it addresses covering the surfaces you do not want to get any paint on. A little plastic sheeting will go along way to keeping paint off of floors, window coverings, handrails, cabinets, counter tops, etc... And, if you are not confident with your ability to paint a straight line next to door casing, baseboards, cabinets or hardware protect these surfaces using masking tape. There are two basic types of masking tape white/yellow and blue. The white tape sticks to surfaces better but, can pull off finishes on cabinets or stained woodwork. Blue tape usually will not pull off finishes but, does not stick as well, this will probably be the tape to use for most applications. Always wipe down or dust the surface you will be masking to assure the best tape adhesion possible. If you use blue tape you may need to re-rub down the tape before painting next to it, only mask off areas with blue tape that you will be painting for a given day. With either tapes, do not assume the are a force field that paint will not penetrate, use them as a reference and dry brush the paint next to the edge of the tape and avoid soaking the edge of the tape with a lot of paint, this will cause the paint to "bleed" through giving you an undesired look. If you will need to apply multiple coats of paint, on the first coat, paint as close to the tape as you can, not really getting paint on the tape. With the second coat or a one coat application, you can use the tape more of like a paint barrier and get a little more paint on the tape if you immediately remove each section of tape after painting the section, this will keep the paint from sitting on the tape and "bleeding" behind it. Also, if you get a lot of paint on the tape it is not good to let the paint dry on the tape because some paints (especially the glossier paints) will peel if allowed to dried, with the tape when it is pulled off. White tape should not be left on for longer than a couple of days and I suggest not leaving it on more than a day in areas that receive long periods of direct sunlight. Blue tape can be left on for days, if it will stay on, there again it does not stick as well and may need rubbed down again immediately before painting up next to it. When you plan with split complementary colors, you begin with a single reference color. Next, choose a color from either edge of the complementary color and use it. While the complementary color scheme is a little more obvious, this scheme can fail totally if you just use paler versions of your warm colors. By the same token, picking a a warm undertone for the main contrasting color and combining it with two cool tones will showcase the warm tone.
Cement-water paints are best suited for application to basement walls which are damp as a result of leakage or condensation. To apply these paints, the same procedure should be followed as is described here for painting exterior masonry walls. On the other hand, in some cases there are legitimate reasons for one area to be bad even if the rest of the paint is solid. If poor body work or rust repair was done in the past then maybe just that section of paint will need to be removed. Lets say you were using a 4" Fine China Bristle Paint Brush in some Alkyd Enamel Paint. And lets say the paint did not cover in 1-2 coats being such a dark tint that many do not cover in one coat. What do you do? A good disposable container may be close by in the newly formed 2lb-7oz. Maxwell House Coffee Blue Plastic Container with snap on lid. Cut a small X in the center of lid, filling container up 2-3" of Painters Mineral Spirits or Lacquer Thinner. Placing Paint Brush in container, running handle through lid's X, snapping it shut when not in use, and after each paint application. This will keep Brush moist and ready for next use, with no cleanup in between, only having to blot it dry on a clean rag next time. Maxwell House Container also makes a perfect cut-in bucket having an easy built-in handle right onto container, for ease of handling, and caring for one's Brush. Texture wall paints may also be used on plaster surfaces. The advantages of this type of paint are that one coat economically produces a textured decoration and relieves the monotony of smooth flat paint. It also covers cracks or patches in the plaster more completely than ordinary wall paint. The disadvantages of texture wall paint are that they Collect dust and are difficult to restore to a smooth finish. These materials are available as water-or oil-based paints, are thicker than ordinary wall paints, and may be applied to wallboard as well as plaster to produce textured effects such as random, Spanish, mission, and multicolored.
