How Much Paint For 20 Fence Panels?
Determining how much paint you need for 20 fence panels depends on several factors, including the size of the panels, the type of paint you are using, and whether you plan to apply one or multiple coats. Typically, a standard fence panel in the UK measures approximately 1.8 metres by 1.8 metres. To calculate the total area, you’d multiply the height by the width of a single panel and then by the total number of panels. In this case, each panel has an area of 3.24 square metres (1.8m x 1.8m), resulting in a total of 64.8 square metres for all 20 panels.
The type of paint you choose also impacts the amount required. Different paints have varying spread rates, which is usually indicated on the paint can. A common spread rate for exterior paint is about 12 square metres per litre. Using this as a benchmark, you would need approximately 5.4 litres of paint for a single coat on your 20 fence panels (64.8 square metres ÷ 12 square metres per litre). However, if the wood is untreated or very absorbent, you might need more paint, while a second coat could double the amount needed, bringing the total to around 10.8 litres.
Additionally, consider the condition of your fence panels. New wood or weathered panels may require more paint because they tend to absorb more. Prepping the panels by cleaning and sanding them will ensure that the paint adheres better and lasts longer, ultimately saving on the amount of paint needed for touch-ups in the future. If your fence was previously painted a darker colour and you are switching to a lighter shade, more paint may be necessary to achieve full coverage.
Finally, it's wise to purchase a bit more paint than your calculations suggest to account for any mistakes or extra touch-ups. Paint can vary slightly from batch to batch, so having a little extra from the same batch can ensure a consistent finish. In summary, for 20 standard-sized fence panels, a rough estimate would be around 5.4 litres for a single coat and 10.8 litres for two coats, adjusted for the specific conditions of your fence and the type of paint used.
