Determining whether you would like to spray on or brush/roll on the paint to your home's exterior walls is an important decision that can have a major effect on your project. If you decide to spray on the paint, you may need to spend more money on the sprayer equipment. You may also need to spend more time preparing before each paint session. To use a sprayer, you will need to spend more time taping areas you do not want to be touched by paint, more time to fill the sprayer with paint, and more time cleaning up when you are done for the day. A sprayer and sprayer hose needs to be properly cleaned at the end of each paint session or the paint will dry inside and cause clogs. Also, consider if you are experienced at using a paint sprayer or not. While an experienced painter should be able to get a clean and smooth application of paint with each pass, an inexperienced painter may create drips and spots clumped with paint. The spray though will be able to also reach little cracks and crevices that a paintbrush could never reach. Using a brush or roller to paint your home's exterior is much simpler and much easier to clean. Applying paint is easy, and if you ever need to take a break, it is much easier to put everything away and to start back up where you left off.
