A quart of paint typically covers between 75 and 100 square feet with a single coat. This coverage can vary depending on several factors, including the paint type (primer, interior, exterior), surface porosity (e.g., drywall, wood, masonry), and application method (brush, roller, sprayer). For instance, unprimed or rough surfaces may require more paint than smooth, primed ones.
Understanding paint coverage is essential for accurate project planning and budgeting. Accurately estimating the amount of paint needed avoids material waste and unnecessary expenses, while also ensuring that enough paint is available to complete the project. Historically, paint coverage has been a key consideration, evolving alongside paint technology and the growing need for efficient material usage. From early paints based on natural pigments to modern synthetic formulations, manufacturers have continually refined their products to maximize coverage and improve application properties.
