Choosing the Right Material: A Deep Dive

The material of your 20 foot tarp is arguably the most crucial factor determining its durability, lifespan, and suitability for your intended use. Let's explore the most common materials and their key characteristics:

Polyethylene (Poly) Tarps: The Budget-Friendly Option

Poly tarps are the most common and affordable type of tarp. They are made from woven polyethylene fabric coated with a layer of polyethylene plastic.

  • Pros:
    • Affordable: The least expensive option.
    • Lightweight: Easy to handle and transport.
    • Water-Resistant: Provides basic protection from rain and moisture.
  • Cons:
    • Not as Durable: Prone to tearing and punctures, especially in harsh weather conditions.
    • Shorter Lifespan: UV degradation can shorten their lifespan, especially when exposed to direct sunlight.
    • Lower Tear Strength: Not ideal for heavy-duty applications or high-wind environments.

When to choose a poly tarp: For temporary, light-duty applications where budget is a primary concern. Examples include covering firewood, protecting equipment during short-term storage, or creating a temporary shelter for a single camping trip.

Canvas Tarps: Breathable and Durable

Canvas tarps are made from tightly woven cotton or linen. They are known for their breathability and natural look.

  • Pros:
    • Breathable: Allows air to circulate, preventing condensation and mildew.
    • Durable: More resistant to tearing than poly tarps.
    • Natural Look: Aesthetically pleasing for certain applications.
  • Cons:
    • Heavier: More difficult to handle and transport than poly tarps.
    • Not Waterproof (Untreated): Requires treatment with a waterproofing agent to repel water.
    • Can Shrink: May shrink slightly when wet.
    • More Expensive: Generally more expensive than poly tarps.

When to choose a canvas tarp: For applications where breathability is important, such as covering valuable equipment that needs to be protected from moisture buildup. Also a good choice for creating a more aesthetically pleasing shelter or shade.

Vinyl Tarps: Heavy-Duty and Waterproof

Vinyl tarps are made from a strong polyester scrim coated with a layer of vinyl. They are known for their exceptional durability and waterproof qualities.

  • Pros:
    • Extremely Durable: Highly resistant to tearing, punctures, and abrasion.
    • Waterproof: Provides excellent protection from rain, snow, and other moisture.
    • Long Lifespan: Resistant to UV degradation and can withstand harsh weather conditions.
    • Easy to Clean: Can be easily wiped clean.
  • Cons:
    • Heavier: The heaviest type of tarp, making them more difficult to handle.
    • More Expensive: The most expensive option.
    • Less Breathable: Can trap moisture, potentially leading to condensation.

When to choose a vinyl tarp: For heavy-duty applications where maximum durability and waterproof protection are essential. Ideal for covering large equipment, protecting construction materials, or creating a long-lasting shelter in harsh weather conditions.

Mesh Tarps: Shade and Ventilation

Mesh tarps are made from a woven mesh fabric that allows air to pass through. They are commonly used for shade and ventilation.

  • Pros:
    • Allows Airflow: Provides shade while allowing air to circulate, preventing overheating.
    • Lightweight: Easy to handle and transport.
    • Durable: Resistant to tearing and stretching.
  • Cons:
    • Not Waterproof: Does not provide protection from rain or snow.
    • Limited Privacy: Offers limited privacy due to the mesh construction.

When to choose a mesh tarp: For applications where shade and ventilation are important, such as covering plants, creating a temporary shade structure, or providing ventilation for equipment.

Key Features to Consider

Beyond the material, several other features can significantly impact the performance and suitability of your 20 foot tarp:

  • Thickness/Weight: Measured in mils (thousandths of an inch) or ounces per square yard, this indicates the tarp's durability. Higher numbers generally mean a thicker, more durable tarp.
  • Grommets: Look for reinforced grommets made from rust-resistant materials like brass or aluminum. The spacing and number of grommets will determine how securely you can fasten the tarp.
  • Reinforced Edges: Reinforced edges provide added strength and prevent tearing, especially in high-stress areas.
  • UV Protection: A UV-resistant coating will protect the tarp from sun damage, extending its lifespan.
  • Waterproofness: Ensure the tarp is truly waterproof, especially if you need to protect against rain or snow. Look for tarps with welded seams to prevent leaks.
  • Ripstop Fabric: Ripstop tarps are made with a special weaving pattern that prevents tears from spreading. This is a valuable feature for added durability.
  • Color: Darker colors absorb more heat, while lighter colors reflect heat. Consider the color of the tarp based on your intended use.
  • Size (Actual vs. Cut Size): Be aware that some tarps are sold based on their "cut size," which is the size of the material before it is hemmed and finished. The actual finished size may be slightly smaller.
