Thread: Tyvek tent footprint - alternatives?

I'd guess some of the NZ brands of building wrap will be similar bonded PE material. Has anyone had success using non-Tyvek branded stuff?

Make your own! Get a piece of nylon the size you want - old tent from refuse station shop etc or even a thin bedsheet and waterproof it. Use a mix of silicon sealant and Turps mixed to be a paintable consistency. Paint one side then when dry turn over and paint the other side. This will be more waterproof than any building wrap
