Tempered Glass Camper: Gluing It Back Together

If you're looking to glue a piece of tempered glass to your camper, there are a few steps you should follow to ensure a strong and secure bond. First, you'll need to select the appropriate adhesive for the job. A few options include silicone, construction adhesive, or a specialised product like WEICON Windscreen Adhesive. Once you have your adhesive, you'll need to prepare the surface by cleaning it with a degreaser to ensure the adhesive will stick properly. Next, you'll want to apply the adhesive to the glass and the camper, making sure to follow the instructions on the product you've chosen. Finally, you'll need to carefully position the glass and apply pressure to create a strong bond. It's recommended to tape the glass in place while the adhesive cures, and you should avoid using your camper for 24 hours to allow the adhesive to fully set.

Choosing the right adhesive

When it comes to choosing the right adhesive for your camper's tempered glass, there are several options to consider. The type of adhesive you choose will depend on the specific material you are bonding to the glass, as well as the environmental conditions the adhesive will need to withstand. Here are some options to consider:

Silicone

Silicone is a versatile adhesive that can be used for bonding tempered glass to various materials. It is known for its flexibility, water resistance, and ability to withstand extreme temperatures. Silicone is a good option if you need an adhesive that can seal gaps and withstand vibrations and impacts. However, one challenge with silicone is finding a suitable applicator that can reach tight spaces.

Construction Adhesive

Construction adhesive is another option for bonding tempered glass to materials like wood, metal, or fibreglass. It comes in a tube form and can provide a strong bond. Combining it with bolts and using silicone to seal the edges can enhance the overall strength and durability of the bond.

Windshield Adhesive

If you are repairing or replacing a windshield in your camper, a specialised windshield adhesive is a good option. These adhesives are designed to bond glass to the frame and are available at most auto parts stores. It is important to follow the instructions and use any recommended primers to ensure a secure bond.

Butyl Tape

Butyl tape is commonly used to seal framed RV windows. It creates a waterproof and flexible seal between the glass and the frame. Over time, it may need to be replaced due to wear and tear. Butyl tape is typically applied by warming it with a hairdryer and then rolling it into place.

Sikaflex

Sikaflex is a brand of glass adhesive that is commonly used in RVs and cars. It is known for its strength and ability to bond metal to glass. It is often recommended by RV and automotive enthusiasts for its durability and ease of use.

Epoxy

Epoxy adhesives, such as JB Weld, can also be used for bonding metal to glass. However, it is important to consider the difference in expansion rates between the glass and metal when exposed to temperature changes. Epoxy may not be as flexible as other adhesive options.

When choosing an adhesive, it is important to consider the specific materials you are bonding, the environmental conditions, and the strength and flexibility required for your application. Following the manufacturer's instructions and preparing the surfaces properly will also contribute to a strong and durable bond.

Preparing the surface

Before gluing the tempered glass on your camper, it is important to prepare the surface to ensure a strong and durable bond. Here are the steps you can follow:

Clean the surface:

Use a heavy-duty degreaser or an activating cleaner to remove any dirt, grease, or contaminants from the glass and the camper's surface. This step is crucial as it ensures that the adhesive will bond properly to the surfaces.

Mark the area:

Measure and mark the area on the camper where the tempered glass will be glued. This will help you apply the adhesive accurately and avoid any mistakes. You can use masking tape to mark the area and protect the surrounding surface.

Choose the right adhesive:

Select an adhesive that is suitable for bonding glass to the material of your camper. In most cases, a strong adhesive such as a windshield adhesive or a silicone sealant will work well. Make sure the adhesive is elastic and can withstand vibrations and shocks.

Prepare the adhesive:

Read the instructions on the adhesive carefully and prepare it according to the manufacturer's guidelines. Some adhesives may require the use of a primer or an activator to enhance the bond. Wear gloves during this process to protect your hands and the adhesive surface.

Apply the adhesive:

Using a sealant gun, apply the adhesive to the marked area on the camper. Apply a generous amount, creating a thick line or "worm" of adhesive. Make sure to leave a minimum of 15 mm to the edge of where the glass will be placed.

Prepare the glass:

Clean and degrease the edges of the tempered glass that will be in contact with the adhesive. This will ensure a strong bond between the glass and the adhesive. You may also need to measure and mark the glass to ensure proper alignment during installation.

By following these steps, you will effectively prepare the surface for gluing tempered glass to your camper. Remember to work in a dust-free and dry environment to ensure the best results. Always refer to the specific instructions and recommendations provided by the adhesive manufacturer.

Applying the adhesive

The application of the adhesive is a crucial step in the process of gluing tempered glass to your camper. Here are some detailed instructions to ensure a strong and durable bond:

Step 1: Prepare the Adhesive Surface

Before applying any adhesive, it is essential to clean and prepare the surface. Use a degreaser or a specialised cleaner like an activating cleaner to remove any contaminants, surface oils, or grease from the bonding area. This step ensures that the adhesive will adhere properly to both the glass and the camper's surface.

Step 2: Choose the Right Adhesive

Not all adhesives are created equal. For gluing tempered glass to your camper, it is recommended to use a specialised adhesive designed for bonding glass and windows. Look for an adhesive that is strong, elastic, and offers torsional rigidity. An example of such an adhesive is the WEICON Windscreen Adhesive, which is also a sealant, providing an extra layer of protection.

Step 3: Apply the Adhesive

When you are ready to apply the adhesive, put on a pair of gloves to protect your hands and the adhesive surface. Use a sealant gun to apply a thick line of adhesive (approximately 10mm) along the edge of the bonding surface on the camper. Ensure you leave a minimum of 15mm to the edge of where the glass will be placed. You want to create a "worm-like" line of adhesive that will provide a strong bond.

Step 4: Insert the Glass

With the adhesive in place, it's time to insert the tempered glass. Make sure you have a helper for this step as glass can be heavy and awkward to handle. Carefully lift the glass, ensuring it is the correct way up and aligned with the adhesive. When you are confident it is in the right position, lightly push the glass onto the adhesive. You can wiggle it slightly to adjust, but remember that once it's on, it's on.

Step 5: Apply Pressure and Tape

Once the glass is in place, apply light pressure to the opposing edges (top and bottom, sides, and corners) to ensure an even bond. Then, use tape to secure the glass in place. The tape will prevent the glass from sliding or shifting while the adhesive cures.

Step 6: Check the Rubber Trim

Before leaving the glass to cure, check the rubber U-trim that goes around the cut-out. Ensure that the adhesive has not pushed it out of place. If it has, gently tap it back into position using a plastic hammer.

Step 7: Allow Curing Time

The final step is to allow the adhesive to cure. Do not use the camper or get the window wet for at least 24 hours. This curing time ensures that the bond is strong and fully dried before exposing it to any stress or moisture.

By following these detailed steps for applying the adhesive, you will ensure a strong and durable bond between the tempered glass and your camper. Remember to take your time, work in a dust-free and dry environment, and always prioritise your safety when handling tools and adhesives.

Installing the glass

Now that you have the correct glue, it's time to install the tempered glass in your camper. Here's a step-by-step guide to help you through the process:

Prepare the glass and the frame:

• Clean the glass and the frame thoroughly to ensure that there is no dirt, grease, or residue that might interfere with the glue. You can use a glass cleaner and a soft cloth for this step.
• If needed, apply a primer to the glass and the frame. This will help the glue adhere better and create a stronger bond. Check the instructions on your specific glue to see if a primer is recommended or required.

Apply the glue:

• Put on gloves to protect your hands and ensure that you don't leave fingerprints on the glass or contaminate the adhesive surface.
• Load the glue into a sealant gun and apply a generous amount to the frame where the glass will sit. Make sure you apply an even coat and don't apply the glue too close to the edge, as it may squeeze out when you install the glass.

Install the glass:

• With the help of another person, carefully lift the glass and position it into the frame. Make sure the glass is the correct way up and aligned properly.
• Gently push the glass onto the adhesive, wiggling it slightly to ensure a good bond. Be careful not to push too hard, especially if you are using tempered glass, as it can break under too much pressure.
• Tape the glass into place to hold it securely while the adhesive cures.

Clean up and finish:

• Check that the rubber trim around the glass is still in place and hasn't been pushed out by the bonding process. If necessary, gently tap it back into place with a plastic hammer.
• Clean any excess glue or fingerprints from the glass and the surrounding area with a suitable cleaner.
• Allow the adhesive to cure for the recommended time, typically around 24 hours, before using the camper or getting the window wet.

Some additional tips:

• Work in a dust-free and dry environment to ensure the best adhesion.
• If you're working with a large piece of glass, consider using suction cups to help hold it in place while you position and install it.
• If you're installing a window, consider using glazing tape in addition to the adhesive for a watertight seal.
• If you're unsure about the process or don't feel confident, consider seeking professional help or advice.

Finishing touches

You're almost done! Now that you've applied the adhesive, carefully insert the new skylight, ensuring it is facing the right way round. The hinge side of the skylight must point in the direction of travel.
