If rubber-base paint has been used, the caustic soda treatment may not be effective and it may be necessary to use an organic solvent type of paint remover. Caution: - When using caustic soda or lye, avoid splashing eyes, skin, and clothing. Composition Wallboard. Composition wallboard usually presents no particular painting difficulties if the ordinary precautions are observed, such as making certain that the surface is dry and free from grease and oil. The painting procedure for wallboard is the same as for plaster; it requires a priming and sealing coat followed by whatever finishes coats are desired, or may be given one-coat flat or resin-emulsion type paint. You will need any of these tools in painting your exterior: caulk, sandpaper, rags and/or paper towels, painter's tape, garden hose, power washer, or hose brush attachment, sponges & buckets for wash water, spray nozzle, stepladder, extension ladder, paint scraper, wire brush, putty knives, heat gun, rotary paint removing tool and electric drill, caulk gun, sanding block, and work gloves.
What are the major color fields in the painting and their role in the entire composition? Is the light optically realistic or expressive as in Matisse's painting? Once the drywall compound/spackle has had sufficient time to dry, you will need to lightly sand the surface of the repair to smooth out any ridges that may have been caused while "coating" the patch. Once you have the surface sanded smooth, take a wet sponge or cloth and, by lightly washing/rubbing, blend the outside edge of the drywall compound/spackle back into the wall. For a smaller repair, you can wash away the excess drywall compound, leaving only the compound/spackle only in the area where the indent was filled. For a larger hole, after filling, sanding and using a wet sponge to blend the outside edge of the compound back into the wall, it may be necessary to texture the area in order to give the smooth patch the appearance of the existing wall. "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. Tools, there is a wide variety of brushes and rollers to choose from, it is critical to select quality tools and maintain them. We will discuss brushes first, I use and recommend only Purdy brand brushes, they will give you the best results in terms of coverage and make the project go much easier and quicker. A Purdy brush is a little more expensive but if kept clean promptly after each use and stored properly, it will last for years and many projects. Most any other brushes out there, especially the cheap ones, are made of far inferior hair and I liken them to using a hand (or whisk) broom to paint with. Using lower quality tools will only frustrate you and lead you to assume that you are incapable of painting. You are capable! and the proper tools, materials, and advise are all you need. If your painting project will be on going for a couple of days, you can wet the brush with paint, wrap the brush up in a plastic sandwich bag and tape the plastic bag to the handle above the metal ferrule. Sealing it up will keep it from drying out, storing it flat will maintain the shape and permit you to use it for a couple of days without cleaning it. Because, after a couple of days or if it has had extended use on a hot day, it will loose its shape and start to collect a lot of dried paint on the hair, you should clean it with warm water and a wire brush. Once you have ran some water through the brush hair, the wire brush will then be used to remove the dried paint from the hair. Always run the wire brush down the entire length of the hair and never across it, to prevent crimping and damaging the hair. After you get the brush clean, spin it between your two hands, shedding as much water as possible from it. Then, using the wire brush again, comb the hair, shape/style the hair with your hands and lay it flat to dry. Once dry, if you will not be using the paint brush again soon, protect it by storing it in the paper shuck/cover that it came in and it will be like new the next time you use it.
