There are many factors that will determine the amount of paint that is used in a project, such as the type of surface being covered, the color of the existing surface, and the color of the chosen paint. A general rule is to calculate the square footage of the surfaces to be painted, and divide by the number of square feet that your selected paint indicates it can cover. For best results, take your measurements and paint information to your local paint retailer. As part of our KNA proposal process, we calculate the paint and primer requirements for your specific project and include the purchase and delivery of products as part of our proposed service.
