This is a large 20 ft. x 40 ft. blue polyethylene tarp built for heavy outdoor work: covering firewood, hay, trailers, roofs, lumber and equipment. It uses 8 mil woven virgin polyethylene at 155 GSM with a 10x14 weave, laminated on both sides, so it sits above the thin 3 to 5 mil tarps sold for light yard use but below canvas or PVC-coated heavy tarps. Edges are double-stitched and rope-reinforced, with metal grommets every 24 in., and the tarp is UV stabilized and mildew resistant. It is sold at finished hemmed size, so the labeled dimensions are the usable ones, which is not true of every poly tarp. Buyers of this class of tarp tend to praise the thickness and grommet spacing and note that poly tarps eventually wear at the grommets and stiffen in cold weather.

Owners of heavy poly tarps like this one generally judge them by thickness, grommet spacing and how the hem holds up in wind. The 8 mil weight and 24 in. grommet spacing are the features most often called out, while long-term sun and wind exposure are the usual complaints.
This is a heavy duty blue polyethylene tarp measuring 20 ft. x 40 ft. It is made for outdoor and rural jobs. The size is the finished, hemmed size, so the labeled dimensions are the dimensions you get.
The tarp is woven from 100% virgin polyethylene with a 10 by 14 weave count and is laminated on both sides. It is 8 mil thick and falls in the 155 GSM heavy duty weight class. The edges are double-stitched and rope-reinforced, with metal grommets every 24 in.
The tarp is fully waterproof, UV stabilized and mildew resistant on both sides. To clean it, hose off mud, paint, sap or debris and let it air dry. Then refold it along the original creases.
