Can A1 VFC be used on Composite Decking?

You can use A1 VFC on some types of composite decking. Only things A1 VFC have issues bonding to are polypropylene (PP), polyethylene (PE) and silicone. For PVC composite decking, AF1 can bond, but if we're needing to bond directly to PP or PE composite plastic, there will be issues. As long as the composite is not one of those materials, A1 VFC will work well.
