Concrete Floors. Two general types of paints for concrete floors are varnish and rubber-base paint. Each has its limitations and the finish cannot be patched without the patched area showing through. Floor and deck enamel of the varnish type gives good service on concrete floors above grade where there is no moisture present.
Suppose it rains while you're working? Vinyl paint dries fast - as quickly as 10 to 30 minutes - and will withstand a shower after that time. It takes another 12 hours to "cure," by then forming an exceptionally tough, long-lasting film that stands up well against weather, sun, salt air and factory smoke.
Take your time there is no rush. There is nothing wrong with having your project take a couple of weeks.
Types of Paint. Water-based paints are usually referred to as emulsions and were traditionally used only for interior walls and ceilings. But recently tremendous advances in paint technology mean that water-based formulas, especially the high-performing acrylics, are available for all surfaces, from woodwork to metal, and for interior and exterior use. The advantages of these paints over oil-based ones is that they are cleaner, have less odour and are more environmentally sound. Brushes can be rinsed clean with water.
Can you get a good paint job from a low buck paint shop? Yes! Professional paint pros and high dollar restorers may scoff, but it's very possible to get a good looking, long lasting paint job from a discount paint shop like Earl Scheib or Maaco. It's not appropriate for every car. I wouldn't hand them the keys to my Shelby GT500 or '53 Corvette, but for those on a budget it's a very good option. The key to a successful budget paint job is to prep the car yourself. Leave nothing to the shop except actually laying down the paint. (note: For purposes of discussion we'll use a classic Mustang as the example, but this process holds true to really any older car)
The correct roller to use depends on the texture of the wall. On smooth walls you will need a 1/2" nap and on textured surfaces it will be more like a 3/4" - 1" nap depending on how rough the texture is. I always recommend a lamb skin, it will lay the paint off the best and provide maximum coverage. A roller pole is also great for saving your back, shoulder and arms from repetitious bending over and extension. If you will be using the roller for a couple of days, the same rule applies as with the brush, seal it in plastic completely to preserve it for the next day. Do not leave the roller submersed in paint or water over night, this will cause premature failure, by releasing the skin from the hardboard backing it is attached to. If you will be rolling a rough texture, like a stucco, make sure to purchase a roller frame (arm) that is sturdy and will hold up to constant applied pressure.
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.
