Past plastic sheet use ( Walmart painters') had several on hand. If one sheet was sanded, no water for washing off then I threw it away, opened a new one.

But long distance away from Walmart ( a new wilderness definition...where's the map ) ?

using a real tough coated nylon ground cloth, more likely to shed sand, less electrostatic clinging, but $$$, looms as probable. Eyow, factory tarps are expensive.

Sand tears the &Hi#234 out f tent floors. Five nights and no floor.
