The blades on the ceiling fan on the back patio have cratered with age.(Cheapo fan;2 blade; 36") Material looks like a hardboard; but not wood. Can anybody suggest a material? Have thought about cheap paneling; but might be too heavy.
Even the very expensive fans out on a patio blades will over time start to sag. The plastic ones are not susceptible to water but heat messes them up. Most are made from pressed wood so just get a new set of blades and if and when they sag again by then you should be ready for a hole new fan.
