Wood Fence Paint Formula:
The Wood Fence Paint Calculator estimates the amount of paint required to cover a wooden fence in the UK, accounting for painting both sides of the fence. It considers length, height, paint coverage rate, and number of coats needed.
The calculator uses the formula:
Where:
Explanation: The formula calculates the total surface area (both sides), divides by the coverage rate to get litres per coat, then multiplies by the number of coats.
Details: Accurate paint calculation helps avoid waste, ensures you purchase the right amount, saves money, and prevents project delays due to insufficient materials.
Tips: Measure fence length and height accurately. Check the paint can for coverage rate (typically 8-12 m²/litre for fence paints). Consider an extra 10% for wastage and uneven surfaces.
Q1: What is a typical coverage rate for fence paint?
A: Most fence paints cover 8-12 m² per litre, but always check the manufacturer's specifications on the paint can.
Q2: Why multiply by 2 in the formula?
A: This accounts for painting both sides of the fence, which doubles the surface area compared to painting just one side.
Q3: How many coats are usually needed?
A: Most fence paints require 2 coats for optimal coverage and durability, but some high-quality paints may only need one coat.
Q4: Should I add extra for wastage?
A: Yes, it's recommended to add 10-15% extra to account for wastage, absorption by wood, and uneven surfaces.
Q5: Does wood type affect paint coverage?
A: Yes, rough or porous woods may require more paint. New pressure-treated wood often absorbs more paint than previously painted surfaces.
