Anti-Rust Paint Calculator
Calculate the amount of anti-rust paint needed for metal surfaces based on area, coverage rate, and number of coats.
How to Use the Anti-Rust Paint Calculator
- Enter the total metal surface area in m².
- Enter the paint coverage rate in m² per litre.
- Enter the number of coats.
- Click Calculate to see paint volume and can count.
使用例
- •Protecting steel structures from corrosion.
- •Estimating paint for bridge and industrial maintenance.
- •Painting gates, fences, and metal roofing.
- •Cost estimation for protective coating projects.
計算式
Paint (L) = Surface area / Coverage rate × Number of coats. Cans = ⌈Litres / 5⌉.
よくある質問
How many coats of anti-rust paint do I need?
Two coats are standard for most applications; three coats for highly corrosive environments or submerged surfaces.
What is a typical coverage rate?
Most anti-rust primers cover 8–12 m²/L on smooth metal; rough or pitted surfaces reduce coverage.
