Why Add Grommets to Your Tarp?
Adding grommets might seem like a small detail, but their impact on a tarp’s functionality is huge. Think about it: a tarp without proper tie-down points is like a beautiful rug without a place to put it – it just doesn’t work as well as it could! Grommets are those sturdy, metal rings that you can thread rope, bungee cords, or ties through. They provide a reinforced hole that prevents the fabric from tearing under stress.
Common Uses for Grommets on Tarps:
Securing to Structures: Imagine needing to tie down a tarp to a fence, posts, or roof. Grommets are essential for a tight, secure fit that won’t budge in the wind.
Creating Tie-Down Points: Whether you’re covering a woodpile, a vehicle, or a boat, having evenly spaced grommets means you can distribute the tension evenly, preventing sagging and flapping.
DIY Projects: Love creating your own shades, privacy screens, or custom covers? Grommets are your best friend for making sure these projects are not only stylish but also practical and durable.
Repair and Reinforcement: If your existing grommets are damaged or you need more attachment points, adding new ones is a fantastic way to extend the life of your tarp.
Temporary and Permanent Solutions: From outdoor event canopies to emergency weather protection, grommets offer versatile ways to secure your coverings.
The Essential Tools and Materials You’ll Need
Before we dive into the “how-to,” let’s gather our supplies. The good news is that you won’t need a whole workshop full of specialized equipment. Most of these items are readily available at hardware stores or online.
What to Have on Hand:
Grommet Kits: These are typically sold in sets and contain the two metal halves of the grommet (the eyelet and the washer) and a setting tool. You can find them in various sizes. For tarps, a medium to large size is generally best. Look for kits made of brass or plated steel for durability. Many kits also include a tool to create the initial hole.

Heavy-Duty Fabric/Tarp Material: Of course, you need the tarp you want to work on!
Hammer: A standard household hammer will work just fine. A rubber mallet can also be used for gentler settings, but for sturdy tarp material, a metal hammer is often more effective.
Cutting Tool (Optional): If your grommet kit doesn’t have a hole punch, you might need a sharp utility knife, a craft knife, or even a rotary cutter to make the initial hole. Some kits come with a punch tool.
Cutting Mat or Scrap Wood: To protect your work surface when cutting or punching holes.
Measuring Tape or Ruler: For precise placement of your grommets.
Marker or Chalk: To mark where you want your grommets to go.
Flat, Hard Surface: A sturdy workbench, a piece of plywood, or even a concrete floor can serve as your base.
Step-by-Step Guide: How to Put Grommets in a Tarp
Alright, let’s get down to business! Follow these simple steps to add professional-looking grommets to your tarp.
Step 1: Plan Your Grommet Placement
This is where creativity meets practicality! Think about how you will use the tarp and where you need the strongest tie-down points.
Measure and Mark: Use your measuring tape and marker to decide where each grommet will go. Common spacing is every 12 to 24 inches, depending on the size of the tarp and the expected wind or tension. Ensure your marks are at least 1-2 inches from the edge of the tarp to provide sufficient fabric support.
Reinforce the Edges (Optional but Recommended): For extra durability, especially on thinner tarps, consider folding the edge of the tarp over by about an inch or two where you plan to place a grommet. This creates a thicker, more robust area for the grommet to grip. You can secure this fold with heavy-duty fabric glue or stitching if you want it to be permanent.
Step 2: Create the Hole
This is the most crucial step for a clean installation. Your grommet kit might include a specific tool for this, which is highly recommended.
Using the Grommet Kit’s Punch Tool: If your kit came with a punch tool (often a metal rod with a sharp edge), place the marked spot on the tarp over a hard, sacrificial surface (like scrap wood). Position the punch tool precisely on your mark and strike it firmly with your hammer. You want to cut cleanly through the fabric.
Using a Utility Knife: If you don’t have a punch tool, place the marked spot over your cutting mat or scrap wood. Carefully use your utility knife to cut a small circle, slightly smaller than the inner diameter of your grommet. It’s better to cut a bit too small and trim than to cut too large. You can also puncture the center and then carefully work outwards with the knife.
Tip: Always make sure you’re cutting on a protected surface to avoid damaging your floor or table.
Step 3: Assemble the Grommet
Now for the satisfying part – seeing the grommet come to life!
Separate the Grommet Parts: A grommet kit typically has two pieces for each grommet: the eyelet (the part with the flange that will be visible on top) and the washer (a flat ring that goes on the back).
Insert the Eyelet: Place the eyelet part of the grommet from the top of your tarp, through the hole you just made. The flange of the eyelet should be on the “good” or “top” side of your tarp.
Position the Washer: Flip the tarp over so you can work on the back. Place the washer over the shank of the eyelet that is protruding through the hole. The washer should sit snugly against the fabric.
Step 4: Set the Grommet
This step uses the setting tool to permanently crimp the grommet together.
Using the Grommet Kit’s Setter Tool: Most kits come with a setting tool. This usually has a grooved end that fits over the shank of the eyelet and a flat base for the washer. Place the setting tool onto the eyelet’s shank.
Hammer Time: Position the tarp on your hard, flat surface. Make sure the washer is perfectly aligned underneath. Now, strike the end of the setting tool firmly with your hammer. The goal is to press the eyelet and washer together, bending the shank of the eyelet to create a secure hold. You might need a few solid hits.
Check for Security: Gently tug on the grommet to ensure it’s firmly attached. If it feels loose, you may need to strike the setter tool again, ensuring you are hitting it squarely.
Table: Grommet Kit Components and Their Purpose
Understanding the parts of a grommet kit can make the process much clearer.
| Component | Description | Function |
|---|---|---|
| Eyelet | The ring with a flange that sits on the visible side of the fabric. | Forms the visible edge of the reinforced hole and is the primary structural component. |
| Washer | A flat metal ring that fits on the back side of the fabric. | Distributes pressure and creates a solid base for the eyelet to grip, preventing tearing. |
| Punch Tool (if included) | A sharp, cylindrical tool. | Cuts the hole through the fabric for the grommet. |
| Setter Tool (if included) | A metal tool with specific shapes for the eyelet and washer. | Crimps the eyelet and washer together, permanently attaching the grommet. |
| Anvil/Base (if included) | A flat or grooved surface for the washer to rest on while setting. | Provides a stable platform for the grommet setting process. |
Pro Tips for Perfect Grommet Installation
Even with a straightforward process, a few insider tips can elevate your results from good to exceptional.
Achieving Flawless Grommets Every Time:
Practice Makes Perfect: If this is your first time, consider practicing on a scrap piece of fabric similar to your tarp. This will help you get a feel for the tools and the force needed.
Use the Right Size Grommets: Ensure the grommet size (the inner diameter of the eyelet) is appropriate for the thickness of your tarp and the type of rope or cord you plan to use. Too small, and it will be difficult to thread; too large, and it might not provide enough hold.
For reference, standard grommet sizes often refer to the inner hole diameter in inches or millimeters. For example, a #0 grommet is often around 3/16″ inner diameter, while a #2 grommet might be around 7/16″ inner diameter. Always check the kit’s specifications.
Multiple Hits Might Be Needed: Don’t be afraid to hit the setter tool a few times. A firm, controlled strike is better than a weak, glancing blow. Ensure each hit is directly centered and the tool is seated correctly.
Check Tool Alignment: Before hammering, ensure the punch is straight and the setter tool is perfectly aligned with the grommet. Misalignment can lead to bent grommets or a poor setting.
Consider a Grommet Setting Tool/Machine: For very large projects or heavy-duty tarps, investing in a bench-mounted grommet press or a durable hand-held setting tool can make the job faster and more consistent. These tools often provide more leverage and a more precise setting. A reputable resource like Industrial Tool’s guide on grommet machines can offer insight into more advanced options.
Weather the Storm: If your tarp is particularly thick or made of a challenging material like heavy vinyl or canvas, you might need to apply slightly more force or use a heavier hammer. Always proceed with caution to avoid damaging the fabric.
* Clean Edges: After cutting the hole, ensure there are no loose threads or uneven edges that could interfere with the grommet setting. A quick trim with sharp scissors can make a difference.
Frequently Asked Questions About Putting Grommets in a Tarp
Here are some common questions beginner DIYers have about adding grommets to their tarps.
Q1: Can I put grommets in any type of tarp?
Generally, yes! Grommets work well with most common tarp materials like polyethylene (often indicated by a “PE” in the product description), vinyl, canvas, and reinforced plastics. For very thin or stretchy fabrics, you might need to reinforce the area with extra fabric or a bonding agent before adding the grommet to prevent tearing. Always test on a small, inconspicuous area first if you’re unsure.
Q2: How far apart should I space my grommets?
Spacing depends on the tarp’s size and its intended use. For most standard tarps, grommets placed every 18 to 24 inches provide good support. If the tarp will be subjected to strong winds or heavy loads, closer spacing (e.g., 12 inches) might be necessary. Ensure your chosen spacing allows for even tension distribution.
Q3: Do I need a special grommet kit, or can I use any pliers?
While some heavy-duty plier-style grommet tools exist, most kits come with specific punch and setter tools designed for the grommet size. Using standard pliers is usually not sufficient and can lead to bent or improperly set grommets. Forcing it with the wrong tools can damage both the grommet and the tarp. It’s best to use a kit designed for the task.
Q4: My grommets feel loose. What did I do wrong?
A loose grommet usually means it wasn’t set firmly enough. This can happen if you didn’t strike the setter tool with enough force, if the tool wasn’t perfectly aligned, or if the fabric around the hole was too thin. For some types of kits, you might need to slightly adjust the position of the setter tool and strike again. If the fabric is significantly weakened, you might need to place a new grommet nearby or consider reinforcing the area.
Q5: How do I make sure my grommets are waterproof?
Metal grommets themselves can create a small leak point, especially in thinner tarps. If waterproofing is critical, consider using grommets with rubber or vinyl seals, or apply a waterproof sealant around the grommet after installation. For many outdoor applications, the watertightness of the tarp material combined with a well-set grommet is sufficient, but for absolute waterproofing, extra steps can be taken.
Q6: How do I remove a grommet if I make a mistake?
Removing a grommet can be tricky. One common method is to use a Dremel tool with a cutting wheel to carefully cut through the crimped shank on the back side of the tarp. Alternatively, you can try to pry the crimped edges apart with needle-nose pliers or a flathead screwdriver, though this can be difficult and might slightly damage the tarp. For reusable grommets, you might find specific removal tools online.
Q7: Can I put grommets in a tarp that gets wet often?
Yes, as long as the grommets are made of weather-resistant material like brass or stainless steel. Cheaper iron or plated steel grommets can rust over time, weakening them and potentially staining your tarp. Brass grommets are an excellent choice for longevity and corrosion resistance, suitable for marine or outdoor applications.
