Turn old bed sheets into durable waterproof tarps
The following video shows how to take old bed sheets and turn them into durable waterproof tarps.
The reason I am sharing this project here is because it looks to be a more durable tarp than the plastic tarpaulins you would buy at the hardware store and isn’t that expensive for what you get. A cheap tube of silicone caulk is about $5 and the gallon of Naphtha is $10.
From the video it says to find the volume of your bed sheets and use 3/4 of that volume in solvent (naphtha). Then using a ratio of 5:1 (Naphtha:Silicone) combine until the silicone is dissolved into a maple syrup consistency and soak your bed sheet in it. Hang to dry for a day and you have a waterproof fabric tarp.
To be honest I am tired of the UV rays of the sun and wind beating up my cheap plastic tarps and may try this out. This will probably hold up longer durability-wise and I don’t see it losing it’s waterproof ability like some fabrics do because it isn’t just a topical coating that can be rubbed off and silicone is a strong synthetic material that won’t break down as easily or quickly like bees waxed canvas would.
