How to Choose a White Poly Tarp | 12 Mil & 1200 Denier Guide

White poly tarps are a popular choice for outdoor protection where light reflection, durability, and weather resistance matter. But not all white tarps are the same.

Thickness, denier, weave count, and construction all play a role in how a tarp performs over time. In this guide, we’ll break down what these specifications mean and how to choose the right heavy-duty white poly tarp for your application.

What Is a White Poly Tarp?

A white poly tarp is made from woven polyethylene fabric coated for waterproofing and UV resistance. The white surface reflects sunlight rather than absorbing heat, making it ideal for applications where temperature control and visibility are important.

White tarps are commonly used in construction, agriculture, equipment storage, and outdoor coverage where long-term durability is required.

Why Choose a White Tarp Instead of Other Colors?

White tarps offer distinct advantages compared to darker tarp colors:

• Reflect sunlight to help reduce heat buildup

• Improve visibility in work areas

• Provide a cleaner, professional appearance

• Suitable for applications requiring light reflection

While silver tarps offer excellent UV reflection and blue tarps are cost-effective, white tarps strike a balance between performance, appearance, and versatility.

Understanding White Tarp Specifications

Thickness: What Does 12 Mil Mean?

Tarp thickness is measured in mils. A 12 mil tarp is considered heavy-duty and suitable for demanding outdoor use. Thicker tarps resist tearing, punctures, and wear better than lighter options.

---

Fiber Thickness: 1200 Denier Explained

Denier measures the thickness of the fibers used in the woven fabric. A 1200 denier tarp uses thicker, stronger threads than lighter-duty tarps, resulting in improved strength and durability.

---

Mesh Count: Why 14x14 Weave Matters

A 14x14 weave means there are 14 threads per inch in both directions. Higher weave counts improve tear resistance and overall tarp strength, especially in windy or high-stress environments.

---

Grommet Spacing

Heavy-duty white poly tarps typically feature grommets spaced approximately 18–20 inches apart on all sides. This allows for secure tie-downs and even tension, helping extend the life of the tarp.

---

Waterproof and UV Resistance

Quality white poly tarps are:

• 100% waterproof

• UV treated inside and out

• Resistant to fading, rot, and mildew

These features make them suitable for extended outdoor exposure.

---

Common Uses for White Poly Tarps

White tarps are widely used for:

• Construction site coverage

• Agricultural equipment protection

• Hay and material storage

• Vehicle and equipment covers

• Temporary outdoor shelters

• Light-reflective applications

Their versatility makes them a reliable choice across many industries.

How to Choose the Right Size White Tarp

Choosing the right tarp size depends on:

• The object being covered

• Allowance for draping and tie-downs

• Desired overlap

Tarps are typically cut slightly larger before hems and grommets are installed, so finished sizes may be a few inches smaller than listed.
