A quick word on composite decking- many people look at composite decking for their outdoor projects thinking that they will never need to perform any maintenance on the material. Be aware that spilling certain substances such as sunscreen or bug spray on some composite decking will cause what will look like stains on the decking. What's actually happening is the spilled substances are preventing the area of the spill from fading along with the rest of the material. Be aware that your composite decking is sold as low-maintenance, and not maintenance free. Check with your supplier regarding how to keep your decking looking brand new.
