Repairing Snaps On Your Boat: A Step-By-Step Guide

Snaps on boats can come loose and even break, for a variety of reasons, from wear and tear to dropping temperatures. The good news is that, in many cases, you can repair a broken snap yourself. The process will depend on the type of snap and the extent of the damage, but the basic steps involve filling in the hole, redrilling, and then rescrewing or replacing the snap. You can also use a snap crimping tool plier or a hammer for installation.

Filling the hole with epoxy

Inspect the hole: Before starting the repair, carefully inspect the hole that needs to be filled. Look for any signs of wear or damage, and ensure that the hole is clean and free of debris. This is an important step to ensure that the epoxy will adhere properly to the surface.

Prepare the epoxy: Epoxy resin typically comes as a two-part mixture that needs to be combined in the correct ratio. Follow the instructions on your chosen product and mix the epoxy thoroughly. You can also add a tint or colour to match the surrounding surface for a more seamless finish.

Tape the area: Use painter's tape or similar to cover any areas you want to protect from epoxy. This will help create a neat finish and prevent the epoxy from sticking where it's not needed. Make sure to tape off a sufficient area around the hole to avoid any accidental epoxy drips.

Fill the hole: Start by slowly pouring the mixed epoxy into the hole. Fill it slightly over the surface to compensate for any shrinkage as the epoxy cures. If the hole is deep, you may need to fill it in layers, allowing each layer to cure before adding the next. This ensures that the epoxy has the best chance to adhere and creates a strong bond.

Let the epoxy cure: Once you have filled the hole, let the epoxy cure completely. This may take several hours or even longer, depending on the product you are using and the temperature and humidity of your work area. Refer to the instructions on your chosen epoxy for the recommended curing time.

Sand and smooth the surface: After the epoxy has cured, remove any excess material with a hand plane or card scraper. Sand the area if necessary to create a smooth, level surface that matches the surrounding area. This step will ensure that your repair is not only functional but also aesthetically pleasing.

Finish as needed: Depending on the surface and your preferences, you may want to apply a finish to the repaired area. This could be a coat of paint or varnish to match the surrounding area and protect the epoxy. This step is optional but can enhance the appearance and longevity of your repair.

When working with epoxy, always follow safety precautions. Wear protective gear, including gloves and eye protection, and work in a well-ventilated area. Additionally, be sure to dispose of any unused epoxy and cleaning materials properly, following the instructions on the product.

Drilling a new hole to reset the snap

Step 1: Prepare the Work Area

Ensure you have a clear and stable surface to work on. Place the boat cover snap on a flat and sturdy surface. It is important to choose an area where you can securely hold the snap while drilling. Make sure you have all the necessary tools, including a drill, drill bits, safety gear, and a snap replacement kit.

Step 2: Select the Appropriate Drill Bit

Choose a drill bit that is slightly larger than the size of the rivet. This will allow you to drill off the rim of the rivet without damaging the surrounding material. If you are drilling into fiberglass, start with a smaller drill bit (1/8 inch) to test the thickness and then switch to a larger size (9/64 inch) if needed.

Step 3: Drill Out the Old Rivet

Securely clamp the boat cover snap to prevent it from moving. Carefully align the drill bit with the centre of the rivet. Start drilling slowly and with moderate pressure to ensure accuracy. As you progress, you can increase the speed and pressure. Once you have drilled through the rivet, remove the socket and button components with a small flat-head screwdriver.

Step 4: Prepare the New Snap

Follow the instructions provided with your replacement snap to position it correctly. Ensure it is aligned and securely attached to the boat cover or underlying surface. If your snap requires assembly, refer to the instructions in your snap repair kit.

Step 5: Drill a New Hole

If you are reusing the old hole, inspect it for any damage or debris. If the hole is too large, you may need to fill it with epoxy or use a plastic drywall anchor before drilling a new hole. When drilling the new hole, use a hole punch or an awl to create a hole that is the correct size for your new snap.

Step 6: Install the New Snap

Place the snap anvil or die on a flat, stable surface. Position the female section of the new snap onto the post of the dome, ensuring the canvas is smooth. Use a snap setter or punch to deform the post and secure the snap. You can also use a hammer to deliver a sharp blow and set the snap in place.

Step 7: Test and Inspect

Once the new snap is installed, test it to ensure it is secure and functional. Check that the snap fastens and unfastens smoothly and is aligned correctly. Perform a final inspection of your work, making sure all snaps are securely attached and the canvas is not damaged.

Using a snap repair kit

Step 1: Gather Your Tools and Materials

Before you begin, ensure you have all the necessary tools and materials from your snap repair kit. This may include snap fasteners (both male and female portions), a setting tool or pliers, a hammer, a block of wood, a drill, and screws. It is also recommended to have sharp scissors, a sharp pencil, and chalk for marking.

Step 2: Prepare the Surface

Inspect the area where the snap will be installed. If the canvas needs repair, do so before installing the new snap. Reinforce the canvas to ensure the snap will not rip through the fabric. Mark the location where the fastener will be placed.

Step 3: Prepare the Fastener

If you are using a fastener with prongs, chalk the tips of the prongs on the male side of the fastener. Center the chalked prongs over the mark on the fabric and gently tap the prongs to transfer the chalk marks onto the fabric. This will help you accurately position the fastener.

Step 4: Create the Hole

Place a block of wood under the fabric to provide a stable surface. Using a small screwdriver and a hammer, carefully punch holes for the prongs. You can also use a drill for this step, depending on the type of fastener you are using. If using a drill, select the appropriate drill bit size for the material you are drilling into (e.g., fiberglass or aluminum). Always start with a smaller drill bit and increase the size as needed to avoid cracking the material.

Step 5: Install the Fastener

Insert the male fastener into the hole. If it is a pronged fastener, use a small hammer to crimp the prongs down over the backing plate. For other types of fasteners, follow the instructions provided with your snap repair kit. Ensure the fastener is secure and can withstand some pressure.

Step 6: Test and Adjust

Once the new snap is installed, test it to ensure it holds securely. If it feels loose or unstable, adjust the fastener or reinforce the surrounding fabric. You may also need to apply marine adhesive or use plastic drywall anchors for a stronger hold, especially if the original snap pulled through the canvas or left an enlarged hole.

Additional Tips:

• If you are drilling into fiberglass, remember to countersink the hole to clear away sharp edges.
• When drilling into aluminum, use a 9/64 drill bit and increase the size if you meet resistance.
• For windshield metal, use a 1/8” drill bit and proceed with caution to avoid damaging the glass.
• If you are unsure about the thickness of the material or the type of fastener to use, consult a professional or refer to the instructions included with your snap repair kit.

By following these steps and using your snap repair kit, you can efficiently and effectively fix broken snaps on your boat, ensuring a secure and long-lasting hold.

Using a screw-in snap stud replacement kit

A screw-in snap stud replacement kit is a convenient and cost-effective way to fix broken snaps on your boat. These kits are widely available online and typically include all the necessary tools and components for the repair. Here's a step-by-step guide on how to use a screw-in snap stud replacement kit for your boat:

Step 1: Prepare the Surface

Before starting the installation, it's important to ensure that the surface where the snap will be attached is clean and dry. If the snap is being replaced, remove the old snap by drilling out the rivet in the socket piece of the upper half of the fastener. This will allow you to detach both the socket and button components. Repeat this process for the lower half of the fastener as well.

Step 2: Gather the Tools and Components

Screw-in snap stud replacement kits usually come with the required tools and components. Make sure you have the following:

• New snap fasteners (including the eyelet, stud, button, and socket pieces)
• Drill
• Drill bits
• Hammer
• Anvil or die
• Punch or "set"

Step 3: Install the New Snap

Now, you can proceed to install the new snap:

• Insert the post of the "dome" or male portion of the snap through the hole in the canvas or boat surface. If the hole is worn large, sew a patch over it that is four times the area of the hole to reinforce it.
• Place the anvil or die on a flat, stable surface to provide a solid base for hammering.
• Position the female section of the snap (the socket piece) onto the post of the dome. Ensure the canvas or material is smooth and free of wrinkles.
• Place the punch or "set" onto the post and, with a firm tap of the hammer, deform the post down onto the dome. This will secure the snap in place.

Step 4: Ensure Water-Tightness (for Marine Environments)

If you're installing snaps in a marine environment, such as the fiberglass hull of a boat, creating a watertight seal is crucial:

• Use a closed-end rivet with a rubber gasket to seal the hole in the center of the snap.
• Apply an adhesive-backed foam rubber gasket to the surface around the snap. This will create a tight seal and prevent water intrusion.

Tips for Success:

• Always pre-drill pilot holes when installing screw-in snaps to avoid cracking the surrounding material.
• Choose high-quality stainless steel or brass snaps for better rust resistance, especially in marine environments.
• For easier installation, consider using a pop rivet tool or a specialised snap installation tool, such as the SnapRite Surface Mount Stud Die or the Pres-N-Snap Installation Tool.
• When drilling out old snaps or creating pilot holes, use a drill bit that is slightly larger than the size of the rivet or screw to ensure a secure fit.
