Frequently Asked Questions - Fence Painting Calculator
How much paint or stain do I need for my fence?
Paint coverage varies by fence type: wood fences typically need 1 gallon per 200-250 sq ft, metal fences 1 gallon per 300-350 sq ft, and vinyl fences 1 gallon per 400-450 sq ft. Our calculator accounts for fence material, condition, and coating type for accurate estimates.
What's the difference between painting and staining a fence?
Paint provides complete coverage and color change, lasting 5-10 years but requiring more prep work. Stain penetrates wood, enhancing natural grain while providing protection, lasting 2-4 years but easier to maintain. Stain is only suitable for wood fences.
How often should I paint or stain my fence?
Wood fences should be stained every 2-4 years or painted every 5-10 years. Metal fences need repainting every 5-8 years. Vinyl fences rarely need painting but can be painted every 10-15 years for color change. Climate and exposure affect frequency.
What weather conditions are best for fence painting?
Paint when temperatures are 50-85°F with low humidity (less than 50%) and no rain expected for 24-48 hours. Avoid direct sunlight, windy conditions, or early morning dew. Spring and fall typically offer ideal conditions for fence painting projects.
Do I need primer for fence painting?
Yes, primer is essential for bare wood, metal fences, or when changing colors dramatically. Use exterior primer suitable for your fence material. Some paint-and-primer combinations work well for previously painted surfaces in good condition.
