Duct tape is not ideal for use in greenhouses as it degrades and turns to powder when exposed to sunlight. There are dedicated repair tapes for greenhouses made from UV-resistant plastic that are better suited for repairing tears in greenhouse plastic sheeting. These tapes are designed for interior and exterior applications and can withstand cold temperatures. However, some users have reported issues with the adhesive quality of these tapes, with the tape becoming brittle and falling off after a few months.
| Characteristics | Values |
|---|---|
| Adhesion | Some customers report issues with the tape's adhesion, noting that it falls off within an hour of application. |
| Affordability | One customer mentions that the tape is not cheap. |
| Durability | Customers have mixed experiences with the tape's functionality, with some saying it works well and others saying it doesn't work at all. |
| Types | There are different types of duct tape, including coloured duct tape and regular grey duct tape. |
| Alternatives | Pool liner repair tape, packing tape, Gorilla Clear Repair Clear Duct Tape, Duck Brand All Weather Indoor/Outdoor Repair Tape, and tape from a window screen repair kit have all been suggested as alternatives to duct tape for repairing greenhouse plastic. |

What You'll Learn
Duct tape degrades in the sun
Duct tape is a popular adhesive due to its versatility, but it does have limitations. One of its limitations is that it can degrade when exposed to sunlight for extended periods.
The adhesive bond of duct tape can be broken down by UV rays over time. While duct tape can be used for temporary outdoor repairs without any issues, prolonged exposure to sunlight can cause the adhesive to dry out, become brittle, or delaminate. This is especially true if the duct tape is used on a hot surface, as the sealing strength of the tape will decrease faster. Therefore, duct tape may not be suitable for long-lasting applications in direct sunlight, such as repairs on greenhouse plastic, which require a strong and durable adhesive.
Some duct tapes are designed to resist UV rays and are suitable for outdoor use. For example, Premium Grade Stucco Duct Tape is designed to resist ultraviolet light and can be used outdoors. Similarly, "Sticky Ass Tape" is a heavy-duty tape that has been shown to withstand seven months of outdoor testing, including exposure to sunshine, rain, and snow.
To prevent duct tape from degrading in the sun, it is recommended to use a product that has been specially treated for UV protection. This ensures that the tape can withstand prolonged exposure to sunlight without the adhesive breaking down. Additionally, it is important to note that duct tape should not be used on wet surfaces, as it cannot adhere properly, and dirty surfaces, as it requires clean and dry surfaces for maximum adhesion.
In conclusion, while duct tape is a versatile adhesive, it is not suitable for long-term outdoor use as the sun's rays can degrade its adhesive bond. For repairs requiring prolonged exposure to sunlight, it is recommended to use a tape specifically designed for UV protection, such as UV-resistant duct tape or heavy-duty outdoor tape.

There are more UV-resistant tapes
While duct tape can be used on greenhouse plastic, there are more durable and UV-resistant tapes available. Some tapes specifically designed for greenhouses offer extra strength and UV protection to prevent deterioration. These tapes are ideal for repairing tears in polyethylene greenhouse film. For optimal adhesion, it is recommended to wait until the sun is shining, ensuring that both the plastic and the tape are warm.
One such product is the Greenhouse Plastic Poly Permanent Repair Tape, which comes in a UV-clear, extra-strong variety. This tape measures 2 inches by 108 feet and is suitable for both interior and exterior applications. However, customer reviews for this product are mixed, with some reporting issues with adhesion and durability.
Another option is the Gorilla Clear Repair Clear Duct Tape, which measures 1.88 inches by 27 feet. This tape is designed for both indoor and outdoor use and can be found on Amazon. While some users have reported success with this tape, others have noted that it starts to lose adhesion after a week.
In addition to duct tape and specialised greenhouse repair tape, packing tape has also been suggested as a possible solution for repairing greenhouse plastic. One user reported successfully reinforcing the seams of their greenhouse with regular packing tape, which held up against winds of 30 m/s (67 miles per hour).
When choosing a tape for greenhouse repairs, it is important to consider the specific type of plastic used in your greenhouse, the climate conditions it is exposed to, and the level of durability and UV protection offered by the tape. While duct tape may be a quick fix, investing in a tape specifically designed for greenhouse repairs, such as those mentioned above, may provide more long-lasting results.

Some tapes are better for patching
While duct tape is a popular choice for patching up tears in greenhouse plastic, there are other tapes that may be better suited for the job. One option is to use clear duct tape, which can be a good temporary solution, especially if the greenhouse plastic needs to be replaced every few years anyway.
Another option is to use a heavy-duty tape designed specifically for repairing minor tears in polyethylene greenhouse film. Both the tape and adhesive on these types of tapes are UV-protected to prevent deterioration. For example, Amazon offers a Greenhouse Plastic Poly Permanent Repair Tape that is UV-protected and extra strong. However, reviews for this product are mixed, with some customers reporting issues with adhesion.
If you're looking for a more permanent solution, you might consider using a window screen repair kit or upholstery needle and strong thread to patch up any tears or holes. This method may be more labour-intensive, but it could provide a longer-lasting fix.
Additionally, some users have reported success with using pool liner repair tape, foil tape, and packing tape for repairing greenhouse plastic. These tapes may be worth considering, depending on the specific needs and conditions of your greenhouse.

Tape adhesion varies
For example, some users have reported issues with the adhesion of clear repair tape designed for greenhouse plastic, with some saying it falls off within an hour of application and doesn't stay attached to the greenhouse. However, others have found that it works well for them, even in high winds. It is recommended to repair tears in greenhouse plastic when the sun is shining, so both the plastic and the tape are warm, which may improve adhesion.
In addition to clear repair tape, other types of tape such as duct tape, packing tape, and Gorilla Clear Repair tape have also been used for repairing greenhouse plastic. Duct tape may be easier to poke through and does not stick well when wet. Packing tape has been found to be effective in repairing tears in greenhouse plastic in some cases, but it may not hold up under severe solar rays.
Gorilla Clear Repair tape has received mixed reviews, with some users finding it effective for repairing tears in plastic canvas vehicle storage tents, while others have not reported their experiences. Therefore, it is important to consider the specific conditions and surfaces involved when selecting a tape for repairing greenhouse plastic, as adhesion can vary depending on these factors.

Tape can be used to cover sharp edges
There are alternative tapes designed specifically for repairing greenhouse plastic that may be more effective and durable than duct tape. These tapes are often clear, heavy-duty, and UV-protected to prevent deterioration from the sun's rays. However, they can be more expensive than standard duct tape.
When using tape to cover sharp edges, it is important to ensure that the surface is clean and dry for the best adhesion. Applying the tape when the sun is shining can also help, as the warmth will make the plastic more pliable and receptive to the tape.
In addition to tape, other methods for covering sharp edges include using a window screen repair kit with an upholstery needle and strong thread, or applying a mesh or foil tape designed for pipe insulation. These methods may provide a more secure and long-lasting solution than tape alone.
Overall, while duct tape can be used to cover sharp edges, it may not be the most reliable option for greenhouse plastic. Consider using a tape specifically designed for greenhouse repairs or exploring alternative methods for a more durable solution.
