How much paint will you need? It takes about 8 gallons per coat to cover a 2500 square-foot house with wood or metal siding. Two coats are usually recommended, making the cost of paint $640 – $1440 depending on the per-gallon cost. Textured or porous siding, such as stucco or concrete, have a greater surface area and require up to twice as much paint for full coverage.

Unlike wood, metal siding is easy to clean with a solution of water and sodium phosphate, and it dries almost instantaneously. However, it must be sanded and primed with two coats of oil-based primer before it’s painted. Oil-based products are a little more expensive than water-based primers, and they take longer to dry. Applying two coats could add an extra day’s labor to a painting project. House Painting Thornton
