Aside from the size and the material of your home, there are several factors that affect how much it costs to paint your home. If you paint the home yourself you’ll almost certainly spend less than you would if you hired professional painters. If you’re doing a cost comparison, remember to include the cost of painting equipment when you’re tallying the cost of a DIY paint job. You’ll need a ladder, brushes and buckets in addition to the paint itself. For an interior job, you’ll probably want tape and a drop cloth. Thornton House Painting
Most of a projects price is the cost of labor at $25 to $75 per hour. However, most contractors bid out based on the entire project which includes all work hours. Hourly rates are only useful if your pro asks to do the job as “time and materials.” However, be wary of this pricing structure, it usually shows the contractor is uncertain how long the project will take.

One pro tip: the term mineral spirits and paint thinner are sometimes used interchangeably. They are actually very similar. But mineral spirits are more often used indoors because they have lower fumes. Paint thinner is less expensive but has a high VOC (Volatile Organic Compounds). See Mineral Spirits vs. Paint Thinner for a complete run down on the differences between these two products.
Picking exterior house paint colors is a lot different than picking a color for a shirt or a car.  It may help to drive around to observe colors that other homeowners have combined on homes that are of similar size and design as yours.  There are also online resources that provide homeowners with the ability to create virtual makeovers of their home by combining colors together through their software programs as well.
Once you have the approximate square footage that you’ll need to paint, remember that a gallon of paint generally covers between 250 and 400 square feet. You’ll need more if you’re painting a rough, porous material, or if you want to paint a dark house a much lighter color. Depending on your color choice, you may need a more expensive tinted primer to help with the color transition. Thornton House Painters
