How to Bend RV Corner Trim?

It’s no secret that RVing is a popular pastime. What might be a secret to some is how to bend RV corner trim like a pro. In this comprehensive guide, we will answer all of your questions and give you some tips to make the process go as smoothly as possible. Whether you’re just starting out or you’ve been RVing for years, this guide is for you!

Purpose of the Corner Trim in the RV

RV corner trim is a type of L-shaped molding that is used to provide a finished look to the corners of your RV. It is typically made from aluminum or vinyl and can be either straight or curved. Corner trim can be found in a variety of colors and styles to match your RV’s décor.

Purpose of the Corner Trim in the RV

Prevents water from entering your car

One of the main purposes of corner trim is to prevent water from entering your RV. The L-shape of the trim helps to deflect water away from the seam where the two walls meet. This is especially important in areas where there is a lot of rainfall or snowmelt.

It can also help to prevent leaks in your RV’s roof by providing an additional layer of protection against moisture and debris.

In addition to its waterproofing properties, corner trim can also provide some insulation for your RV. By creating a barrier between the outside elements and the interior of your RV, the trim can help to keep your vehicle cooler in summer and warmer in winter.

Aesthetics

Another purpose of RV corner trim is to provide a finished look to the exterior of your vehicle. The trim can help to cover up any gaps or seams in the construction of your RV. It can also add a touch of style and sophistication to the overall appearance of your vehicle.

Many people choose to install corner trim on their RV for purely aesthetic reasons. If you are looking for a way to customize the look of your RV, then installing corner trim may be the perfect solution.

Protects corners of your vehicle from impact damage

In addition to its aesthetic appeal, corner trim can also help to protect the corners of your RV from impact damage. By installing trim on the edges of your vehicle, you can help to reduce the risk of dents and scratches.

If you take your RV off-road or travel on rough roads often, then corner trim can be an essential part of protecting your investment. [1]

Why Would You Want to Replace the Corner Trim in Your RV?

There are several reasons why you might want to replace the corner trim in your RV. One reason is that the existing trim may be damaged or worn and you will need a new one.

Why Would You Want to Replace the Corner Trim in Your RV?

RV trims can get damaged for many reasons. They can become cracked or chipped from impact, or they may fade or discolor over time. RV trims are rust-resistant but that does not mean they are immune to damage.

Another reason you might want to replace your RV’s corner trim is if you are looking to change the look of your vehicle. If you are tired of the existing color or style of trim, then replacing it with a new one can be a great way to give your RV a fresh new look.

Finally, you may also want to replace the corner trim in your RV if you plan to upgrade to a higher-quality trim material.

The new trim might not necessarily match the walls of your RV the same way your old one did, but as long as it’s a minor difference, it can be fixed by bending the corners. [2]

How Do You Bend a RV Corner Trim?

So, you’ve decided to replace the corner trim on your RV. But how do you bend it? The process of bending RV corner trim is not as difficult as it may seem. In fact, with a little patience and the right tools, most anyone can do it.

There are two methods that can be used to bend RV corner trim: the heat gun method and the mallet method. In this article, we will focus on how to bend RV corner trim using both of these!

Prepare the tools you will need

The first step is to gather the tools you will need for the job. For this project, you will use it.

RV trim

Obviously, you will need RV corner trim for this project. You can purchase RV corner trim at most RV parts stores or online retailers. Be sure to measure the length and width of the trim before you buy it to ensure that you get the correct size.

Prepare the tools you will need

Aluminum and vinyl are the two most common materials used for RV corner trim. Aluminum is more durable than vinyl and is less likely to fade over time; however, it is also more expensive. Vinyl is more affordable but not as durable as aluminum; it also has a tendency to fade in sunlight.

Rubber mallet

You will need a rubber mallet to gently tap the trim into place. Do not use a metal hammer, as this could damage the trim.

A rubber mallet is a soft-headed hammer that is typically used for striking wooden or plastic objects. It is designed to minimize damage to the struck object and to prevent marring.

Sealant

After you have bent the trim into place, you will need to apply a sealant to the joints to prevent water from seeping in. You can purchase RV sealant at most RV parts stores or online retailers.

Sealants are used to fill gaps and cracks in order to prevent water damage. They are available in a variety of formulations, including silicone, latex, and acrylic.

When selecting a sealant for this project, be sure to choose one that is compatible with the material of your RV corner trim. For example, if your trim is made of aluminum, do not use a latex-based sealant as it will not adhere properly.

Rough brush

You will need a rough brush to clean the surface of the trim before you apply the sealant. A stiff-bristled brush or scrubber pad is ideal for this task.

Prepare the tools you will need

A rough brush is a type of brush that has stiff bristles. It is used to clean surfaces by removing dirt, grime, and other debris. Stiff-bristled brushes are typically made of nylon or polyester. They are available in a variety of sizes and shapes, including round, flat, andangled.

Screws and screwdriver

You will also need screws and a screwdriver to attach the trim to the RV. Be sure to use screws that are long enough to go through the trim and into the underlying support structure.

It doesn’t matter which screws you use in most cases, but self-tapping screws are incredibly convenient for the job. Self-tapping screws are designed to create their own threads as they are driven into place; this eliminates the need for pre-drilling pilot holes. [3], [4]

Remove the old trim

After you have gathered the tools and materials you will need, the next step is to remove the old trim. This can be done with a screwdriver or a power drill.

Remove all of the screws that hold the old trim in place. Once the screws have been removed, gently pull the trim away from the RV. If the trim is glued or otherwise attached, use a putty knife or similar tool to pry it loose.

With the old trim removed, you should now have a clear view of the underlying support structure. This is what you will be attaching the new trim to. Inspect this area for any damage or decay; if necessary, repair it now before proceeding. [1], [2], [3]

Clean the support structure

Once you have inspected and repaired the underlying support structure, it is time to clean it. This will ensure that the new trim adheres properly.

Use a vacuum to remove any dust or debris that has accumulated over time. You should also use a stiff-bristled brush or scrubber pad to remove any dirt, grime, or debris from the surface. Clean the area thoroughly with soap and detergent, then rinse it with clean water. Once the surface is clean, wipe it down with a damp cloth to remove any remaining dust. Allow the area to dry completely before jumping to the next step.

Make accurate measurements

Now it is time to measure the area where the new trim will be installed. This step is critical; if you do not make accurate measurements, the trim will not fit properly.

Use a tape measure or ruler to determine the length and width of the area, as well as the depth. The depth measurement should be taken from the face of the support structure to the outside edge of the opening. Once you have these numbers, you may want to add a few inches to each measurement to allow for errors.

To ensure that your new trim is installed correctly, it’s best to use masking tape to create a template, or simply mark the dimensions by yourself. Both will serve you as a guide. Simply measure the shape of the trim correctly and then use a pencil to mark where you will need to bend it. [2], [3]

Place the new trim

With the old trim removed and the support structure prepped, you should place your trim in the place it’s supposed to be before bending. Doing so will give you a better idea of how the finished product will turn out to be and helps you to make all the adjustments before fixing it in place.

Start by holding the first piece of trim in place against the support structure. Repeat this process for each piece of trim until the entire area is covered. Once you’re happy with the positioning, it’s time to start bending. [2], [3]

Use rubber mallet to bend the corners

Now that the trim is in place, it is time to start bending the corners. The recommended tool for this process is a rubber mallet as it’s safe to use for aluminum.

Use rubber mallet to bend the corners

Finally, it’s time to start bending the corners. Start by holding the trim in place and then gently tap the corner with the mallet until it’s bent to your desired angle. Repeat this process for all four corners.

Keep in mind that aluminum is a soft metal, so it’s important not to hit it too hard, as you can damage the trim beyond repair. You should also avoid using a metal hammer or random blunt objects for this very reason. Once all of the corners have been bent, go back and check that they are level and even. [1], [2], [3]

Apply the sealant

With the corners bent, you can now attach the trim to the RV. This will help to keep the trim in place and prevent moisture from damaging it.

Use a caulk gun or similar tool to apply the sealant around the perimeter of the trim. Start by applying a generous amount of adhesive to the back of the trim. Work slowly and evenly, making sure that all gaps and seams are sealed. Then press it into place and hold it there for several minutes. Allow the sealant to dry completely before using the RV. [1], [2], [3]

Screw it in place

Once the adhesive has dried, you can now screw the trim into place for extra security. This will ensure that it stays in place, even if the sealant fails.

Use a power drill or screwdriver to drive the screws into the support structure. Start by drilling through the brackets at one corner and work your way around, making sure that each screw is driven in securely. [1], [2], [3]

Remove the sealant excesses

After the trim is installed, you may notice that there is excess sealant around the edges. This can be removed with a putty knife or similar tool. Simply run the blade along the edge of the trim to remove any excess sealant but be careful not to damage the pain cover. [1]

Bending the Trim With Heat Gun

If you don’t have a rubber mallet or you don’t want to deal with unsightly crinkles in your trim, you can use a heat gun to bend the corners.

To do this, first, set your heat gun to the low setting and hold it about six inches from the corner of the trim. Slowly move the heat gun back and forth across the corner until you see the aluminum start to soften. Repeat this process for all four corners.

Once the trim material is soft, carefully bend the corner to the desired angle. You can do this with the rubber mallet as well, just apply less force to it. Hold it in place for a few seconds and then simply allow the trim to cool completely. Be careful while using this method, as too much heat can cause the aluminum to warp or discolor. [1]
