Buying Guide

Finding the right tarp is important for protecting your belongings. A thick poly tarp offers great protection from the weather. John D. was very happy with his tarp to cover firewood.

Here’s a guide to help you find the best thick poly tarp:

Thickness: The thickness of a tarp is measured in mils. A 10 mil or 12 mil tarp is a good choice for heavy-duty use. The thicker the tarp, the more durable it will be.
Material: Polyethylene is a common material for tarps. It is waterproof and UV resistant. Look for tarps with a high-density weave for extra strength.
Size: Think about what you need to cover. Measure the items you want to protect. Make sure the tarp is large enough to cover everything.
Grommets: Grommets are metal rings around the edges of the tarp. They allow you to secure the tarp with ropes or bungee cords. Look for tarps with reinforced grommets for added durability.
UV Resistance: If you plan to use the tarp outdoors, choose one with UV resistance. This will help prevent the tarp from breaking down in the sun.
Waterproof: All poly tarps are waterproof. This is a key feature for protecting your items from rain and snow.
Reinforced Edges: Reinforced edges add extra strength to the tarp. This helps prevent tearing, especially in windy conditions.
