What You'll Learn
Using polycarbonate sheets
If you're repairing a basketball backboard, you may want to consider using polycarbonate sheets. Polycarbonate is 250 times stronger than standard glass, making it a safe and durable choice for a basketball backboard that can stand up to hard knocks. It is also vandal-proof and shock-resistant, so you won't have to worry about any ballers shattering your backboard with a particularly powerful slam dunk!
Polycarbonate sheets are available in a range of colours, thicknesses, and dimensions, so you can choose the one that best suits your needs. You can even get a transparent polycarbonate sheet, which looks good and allows for a clear view of the hoop. If you're making a backboard for a child's basketball hoop, a smaller sheet of around 6mm thickness should suffice.
Polycarbonate is also UV and weather-resistant, so it won't fade or incur sun damage over time. It's perfect for outdoor use and can withstand the elements without yellowing or cracking. Additionally, polycarbonate is fire-resistant, with a fire class of B1, so you can rest assured that your backboard won't go up in flames if it's exposed to an open flame.
When repairing your backboard with a polycarbonate sheet, you don't need to glue it to the backboard. This could add unnecessary time and cost, and it may trap moisture, leading to potential warping of the sheet. Instead, you can use a pop rivet gun to secure the sheet in place without the need for adhesive.

Acrylic sheets as an alternative
While Lexan is a popular choice for basketball backboards, acrylic sheets are also a great alternative. Acrylic, also known as plexiglass, is a cost-effective option that is widely used as a shatter-resistant, durable, and transparent alternative to glass. It is also easy to install and has high clarity, making it a perfect choice for situations where you need the transparency of glass with added protection.
When compared to Lexan, acrylic sheets are more scratch-resistant, have better UV light resistance, and do not turn yellow over time. They are also available in a wide range of colours, from opaque to transparent and translucent options, providing a variety of design choices. Additionally, cut acrylic edges polish well, either through mechanical or flame polishing.
In terms of strength, Lexan polycarbonate sheets are considered stronger and more impact-resistant than acrylic. Lexan is virtually unbreakable and is about 250 times more impact-resistant than glass. It is also more flexible and can be cold-bent without heating, making it a good choice for applications where impact resistance is a priority. Lexan can also withstand boiling temperatures, which is why it is commonly used for kitchenware and electronic appliances.
However, despite being stronger and more impact-resistant, Lexan is more prone to scratches, and these minor scratches cannot be polished away. Acrylic sheets, on the other hand, are easier to maintain and are more resistant to chemical reactions and gasoline. They are also lighter in weight, which contributes to their cost-effectiveness.
When repairing a basketball backboard, it is ideal to replace it with a material similar to the original. So, if you are looking for an alternative to Lexan, acrylic sheets are a great option. They offer durability, flexibility, and impact resistance, along with a range of colour options and excellent scratch resistance.

Repairing sun damage and fading
Lexan is a trade name for polycarbonate, which is known for its impact resistance and toughness. However, it is prone to sun damage and can be difficult to restore to its original condition. Here are some detailed instructions to help you repair sun damage and fading on a Lexan basketball backboard:
Identify the Damage
Firstly, it is important to understand the type and extent of the sun damage. Inspect the backboard for any signs of discoloration, fading, or oxidation. Check if the UV protective layer has been compromised, as this will make the Lexan more susceptible to sun damage. Look out for any cracks or deep scratches, as these can be more challenging to repair.
Clean and Prepare the Surface
Give the backboard a thorough cleaning to remove any dirt, grime, or residue that has built up over time. This step will ensure that the repair methods can effectively adhere to the surface. Use a mild soap or detergent and warm water, and gently clean the affected areas. Ensure the backboard is completely dry before proceeding.
Sanding and Polishing
Sanding and polishing can be effective in reducing the appearance of scratches and restoring some clarity to the Lexan. However, it is important to note that this method may not achieve a "like new" result, especially if the damage is severe. Start by using fine-grit sandpaper and gently sand the scratched or damaged areas in a circular motion. Be cautious not to apply too much pressure, as Lexan is softer than other plastics and can be easily deformed. After sanding, you can apply a small amount of plastic polish or car compound to the surface and work it into the material with a microfiber cloth. Polish in a circular motion until the haze created by the compound disappears, revealing a clearer surface.
Apply Protective Coatings
To enhance the protection of the Lexan backboard against future sun damage, consider applying a protective coating. You can find Lexan-specific coatings, such as a scratch-resistant coating or a UV-resistant coating, which will help prolong the life of the backboard. These coatings can be applied in a similar manner to the polishing process, using a microfiber cloth and following the manufacturer's instructions.
Prevention and Maintenance
To minimize future sun damage, take preventive measures. Store the basketball backboard in a shaded area or indoors when not in use. Regularly clean and maintain the backboard, washing it with mild soap and water, and consider applying a wax coating to protect against UV rays. Additionally, you can cover the backboard with a tarp or sheet when it is not in use for extended periods, shielding it from direct sunlight.
Remember, while these methods can help repair and restore sun-damaged Lexan, the results may vary depending on the severity of the damage. In some cases, it may be more practical to replace the backboard or opt for a different material that is more resistant to sun damage and discoloration.

Fixing cracks and holes
If your Lexan basketball backboard has cracks and holes, you can repair it by overlaying an acrylic or polycarbonate sheet onto the broken backboard. Here is a step-by-step guide:
Prepare the Backboard
Sand down any cracks with large-grit sandpaper to smooth out the surface. Ensure you scuff up the entire backboard so that the adhesive has something to grip onto.
Cut the Acrylic Sheet
Lay your sheet of acrylic over the backboard and trace the outline with a marker. Cut the acrylic sheet along the traced marks using a suitable saw, such as a jigsaw or band saw. Sand the edges of the acrylic sheet with fine-grit sandpaper until it is smooth to the touch.
Attach the Acrylic Sheet
Apply acrylic adhesive to the backboard and then place the acrylic sheet on top, clamping it in place as the adhesive cures overnight. Alternatively, you can use pop rivets to attach the sheet without the need for glue. This method prevents moisture from becoming trapped and potentially warping the sheet.
Reassemble the Hoop
Once the adhesive is fully cured, screw the hoop back into the backboard and reattach the assembly to the support pole. If you used pop rivets, you can drill holes at the tip of each crack to prevent further webbing and then reassemble the hoop.
Test the Repair
Before playing a game, test the security of the backboard by taking a couple of hard shots. If the backboard holds up, you're ready to play!
Note: While these steps can repair a damaged Lexan backboard, it is recommended to consider replacing the entire backboard if the damage is extensive. Polycarbonate is a popular choice for replacement backboards due to its strength, transparency, and weather resistance.

Replacing the entire backboard
If your basketball backboard is damaged, you may want to consider replacing the entire backboard. This is often the best option if the backboard has incurred too much damage.
Firstly, you will need to gather the right materials. Polycarbonate is a popular choice for basketball backboards due to its strength, transparency, and weather resistance. It is also easy to work with, as it can be sawed, milled, glued, and drilled. You can order polycarbonate sheets in a range of thicknesses and dimensions to suit your needs. Alternatively, you could opt for plywood, which can be bolted onto the metal frame of the backboard.
Before installing the new backboard, you will need to remove the old one. This is a two-person job to ensure it is done safely and correctly. Lay the basketball hoop on its side, and carefully remove the rim and the old backboard from the mount. Be sure to save the rim and any bolts and screws that you remove.
Once the old backboard has been removed, you can proceed to install the new one. If you are using polycarbonate, you can drill holes in the sheet to match up with the mount. You can then secure the polycarbonate sheet to the mount using bolts or screws. If you are using plywood, cut the plywood to the appropriate size and shape, and bolt it securely to the metal frame.
Finally, you may need to repaint the lines on the backboard. You can use your school colours or any other design you prefer. And that's it! You've successfully replaced your basketball backboard.
