Frequently Asked Questions
How many gallons of paint do I need for a standard house?
A good rule of thumb is to calculate the total surface area by multiplying the height of your walls by their length. Generally, one gallon covers about 350 to 400 square feet with a single coat. Always buy an extra gallon to account for touch-ups and texture absorption.
Do I really need to use a primer first?
Priming is essential if you are making a drastic color change or painting over raw, unsealed wood. It creates a uniform surface that helps the topcoat stick properly and prevents the old color from bleeding through. If the current paint is in good shape, a high-end all-in-one product might suffice.
Why does my gray paint look blue once it is on the house?
This happens because gray is a neutral color that picks up ambient light from the sky. If your home is surrounded by open sky or lush green trees, the blue or green undertones in the gray will become more prominent. You can counteract this by choosing a gray with a slightly warmer, brown base.
How often will I need to repaint my gray exterior?
Quality exterior paint typically lasts between five to ten years depending on your local climate. Areas with extreme heat or heavy rain will naturally wear down the finish faster than mild, dry environments. Inspect your siding annually for signs of peeling or fading to catch issues early.
Is it better to choose a light or dark shade of gray?
Light grays are safer for homes in hot climates because they reflect heat and stay cooler during the summer. Darker shades provide a sophisticated, dramatic appearance that works exceptionally well on modern architectural styles. Just keep in mind that dark colors highlight dust and pollen much more than lighter tones.
