Duct tape is a product with, quite literally, a million uses. Ask anyone, and they will probably have a story to tell about how duct tape saved the day without expensive repairs. People all over the world swear by it. No builder or handyman would leave it out of their toolbox. One of its many uses is joining, connecting, or sealing PVC pipes.
Duct tape does stick to PVC pipe. Under conditions where the PVC pipe is clean, free of moisture, and the duct tape is applied correctly, the tape will adhere with a strong bond. Poor surface preparation and poor tape application are the leading causes of duct tape not adhering well to PVC pipe.
Be careful though, a few small mistakes in the preparation of the pipe surfaces or the application of the tape can mean the difference between a job well done and having to stick the tape over and over again.
Why A Clean Surface Is A Must When Applying Any Kind Of Tape
It’s easy to skip the first step of cleaning the surface of the PVC pipe before sticking down the duct tape because most of the time, you want to get the job done as quickly as possible with the least amount of fuss, but doing it right the first time will often mean not having to do it a second time!
When a PVC pipe is dirty or greasy, the duct tape will stick to the layer of dirt or grease first and have less contact with the pipe itself. Essentially, there is a layer of non-sticky material between the PVC pipe and the adhesive on the duct tape, which will stop it from adhering fully to the pipe.
To clean the PVC pipe before sticking the duct tape to it, do the following:
- Use a damp cloth to thoroughly wipe away dust and dirt on the surfaces where the duct tape will be stuck.
- If the pipe is greasy, you may want to use a household detergent in the water, making sure to rinse the soapy water off the pipe after.
- Allow the pipe time to dry completely.
Once the PVC pipe is clean and dry, go ahead with the application of the tape.
How To Correctly Apply Duct Tape To A PVC Pipe
These few pointers will have you applying duct tape to PVC pipe like a pro!
- Check the area around the pipe for obstructions. This may seem like an unnecessary tip, but duct tape is a very sticky product and often ends up sticking to the wrong surface or to itself that sometimes ends in a sticky mess. Planning where and how you will stick the tape, if there are any obstructions around the pipe, or the size of the space you will work in may save you multiple attempts.
- If you know the size of the surface of the PVC pipe that you need to cover with the duct tape it may be useful to cut that length of tape before applying it. If you are not sure how much surface area you will need to cover you may prefer to keep the tape on the roll and cut it when you are finished.
- Pro tip: Hold the length of tape in both hands and make sure the duct tape is taught in the middle.
- Applying the tape: Using one hand, firmly place about a ½ inch of tape, sticky side down, on the PVC pipe. Using the hand you have just freed up secure that ½ inch of tape by rubbing it down with your thumb or the heel of your hand to make sure it is secure.
- Keeping the tension on the tape use your free hand to firmly stick down the tape to the pipe inch by inch. Don’t stick down the other end and then rub it in the middle as this often causes bubbles or ripples.
- When wrapping the tape around a PVC pipe it may be necessary to start at a slight angle and create a spiral effect with some overlap of the tape as you go.
With these instructions, you should be able to apply duct tape to a PVC pipe with ease. But what happens if you have stuck tape to a pipe before, but for some reason, it isn’t working now?
Duct Tape Stuck To PVC Pipe Before, But Now It Won’t
If you find yourself in a situation where you have stuck duct tape to a PVC pipe or any other surface before, it worked just fine back then, but when you try to reapply it now, it won’t work. You need to ask yourself what has changed? Is it possibly hotter or colder than when you first applied it? Is there maybe moisture in the air?
If you can identify what has changed, you may recreate the original conditions and apply it again. For instance, you could wait until it is cooler in the evening or heating the room a little, or placing the tape in a warm place for a while before trying again.
Duct Tape May Only Be A Temporary Solution For PVC Pipes
Depending on your reasons for sticking duct tape to a PVC pipe, it may only be a temporary solution. Because duct tape adhesive is made from rubber compounds, it responds to heat and cold. If the PVC pipe is exposed to heat and cold, it may pull the tape and loosen it over time.
Duct tape also comes in different grades, with some being stronger than others. Depending on the grade of duct tape used on your PVC pipe, you may find it has a shorter lifespan than you thought it would. Check the grade of duct tape at the hardware store to ensure you have the right tape for what you want to achieve.
If sticking duct tape to a PVC pipe was to repair a leak in the pipe, you may want to check the pipe regularly to see that the duct tape is holding, especially if the pipe is pressurized. It could also be that you need a temporary fix until a plumber or other professional can come to fix the pipe. In this case, duct tape may be the perfect answer.
If you have used duct tape to seal a leaking PVC pipe and the leak pushes through the tape, you should consider a more permanent solution.
Duct Tape Is A Good Solution When Using PVC Pipes
Duct tape is great for sealing, joining, and connecting PVC pipes. With some good preparation, some practiced application techniques, and a keen eye on the pipe, after applying the duct tape, it should stick well and stay stuck!
