Masonry Walls and Ceilings. Interior masonry walls and ceilings above grade may, in general, be painted in much the same manner as plaster surfaces. Here again, it is necessary to allow adequate time for the masonry to dry before applying paint and, in addition, attention should be given to the preparation of the surface. When decorating a wall containing Portland cement (concrete, for example), it is essential to take precautions against the attack of alkali. For this purpose, alkali-resistant primers such as rubber-base paints may be used when oil paints are to follow. Plastic sheathing and masking tape was not available at the end of the painting project for whatever reason, I have no idea, but you have a Paint Brush that if not cared for will eventually dry up. Last solution that works well, is to take a sopping wet rag, wrapping the Paint Brush up like that burrito you missed wrapping up earlier. This will buy you some time until either you use the paint brush again, or you can properly clean it. Like this, it will actually take quite a while to reach a number that is close enough to the yellow color you've chosen that you can't tell any difference (and mathematically, you will never actually reach an average of 4!)
Scuff for paint. Once your Mustang is totally stripped of exterior chrome it's time to scuff up the existing paint. The paint shop should do this also, but on the lower end paint packages they won't spend much time here. It's better for you to do it so you know it's done thoroughly. By far, the most important characteristic in determining whether you are Warm or Cool is your hair color. If you can't determine your exact eye or skin tone, then your hair color will provide the answer. Why? It frames your face! Practically every manufacturer has a "color system," a fat book of color chips with instructions for duplicating each chip. This is accomplished by intermixing cans of colored paint, by adding a concentrated color to a can of white or colored paint, or by adding concentrated color or colors to a can of neutral "base" paint. And for those who don't want any guesswork there's the Color Carousel that mixes the paints right in the store. Whatever the method, the result is a range of colors such as no amateur painter has seen. 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.
