How to Make 3m Tape Sticky Again? (A Detailed Guide)

If your 3M tape is not sticking or if it is falling off of a surface after a short time, there are many ways to make the tape sticky again.

The first thing that you should do if your tape isn’t sticking is to rewet it with more water. If the tape is brand new, try wetting it in clean warm water. If the tape is a little bit older, try scrubbing it with a rag and a little bit of rubbing alcohol. This can be especially helpful if the tape has been sitting in the garage or basement for years without being used and has dried out considerably.

If your tape still isn’t sticking after rewetting it, there are a few more things that you can try before throwing it away or buying new tape. You can try using heat to make your tape sticky again.

Using an iron on low heat, carefully run over the back of the tape for about 1 minute until it starts to bubble up again. Be careful not to burn yourself!

You can also try adding 3M Auto Exterior Attachment Tape to your car if you are having issues with it not sticking well anymore.

3M Auto Exterior Attachment Tape

The adhesive on the Mounting Strip backing makes this tape safe for use on car paint. It will stick very strongly and have excellent strength, especially under heat and cold conditions. This tape is well suited for mounting electronic accessories to your car or SUV.

The downside to using this solution is that it can leave an oily residue behind on the surface where the tape was applied and can cause staining over time.

The residue can be cleaned up with some rubbing alcohol or paint thinner, but you should take care when using those products in case they stain your surface as well.

Applying tape to smooth surfaces is a useful and effective means of holding items in place. However, it can be frustrating if the tape doesn’t stick or if it falls off after only a short period of time.

This usually indicates that the adhesive on the tape has failed or has dried out. Fortunately, there are ways to make 3M Scotch Tape sticky again with two methods that you can try yourself.

Method 1: Use Nail Polish to Reactivate 3M Tape

Take a small amount of nail polish and apply it to the sticky side of the tape. The nail polish will help to reactivate the adhesive on the tape and allow it to stick as normal once more.

Apply a little bit of pressure and let the nail polish dry for several hours before attempting to use the tape again.

Method 2: Use Rubbing Alcohol to Reactivate 3M Tape

Rubbing alcohol is another alternative for making 3M Scotch Tape sticky again. Dip a cotton swab into some rubbing alcohol and rub it over the end of each piece of tape that you want reactivated. Let it air dry for several hours before attempting to use it again.

Do not use either method on colored tapes or tapes that have an adhesive backing other than 3M Scotch brand tape.

Tips: Adhesives do not like to be exposed to air when they are curing, so protecting them from air is very important.

Why Tape Won’t Stick to Car Interior?

Why tape won't stick to car interior

When 3M™ tape won’t stick, it’s usually due to one of the following reasons:

The Surface is not Clean

The surface is dirty or contaminated. The tape will not stick to a dirty surface. Try cleaning with alcohol and then allow the surface to dry completely before attempting to apply the tape.

The Surface was not Prepared Properly

Clean the surface and ensure it is free of dirt and oil. Then make sure you are applying tape at a temperature above 50° F. For optimum adhesion, apply in temperatures between 60° F -100° F. Make sure the backing on the tape is clean and free of dust or dirt as well.

Tape has been exposed to high heat. High temperatures can cause a release agent on the back of some tapes to melt, which in turn causes the adhesive to lose its bond to itself and or the substrate.

The 3M™ automotive masking tape does not have this problem as it has a special release agent that does not melt at car body shop temperatures (180-350 degrees F.).

How to Make Tape sticky Again

There are many ways of making tape sticky again. Tape loses its stickiness because of heat, humidity, UV rays, and time.

1. Heat: Heat is the biggest enemy of sticky tape. If you have a roll of tape that has become less sticky over time, put it in your oven at 220 degrees for five minutes. You can also microwave the tape for 30 seconds to restore its stickiness, but be careful not to melt the tape!

2. Humidity: If you are using a roll of peeling tape, you may get better results if you let it sit out in the sun for a couple hours and then try to use it again.

3. Tape will also lose its stickiness if it comes in contact with paint or varnish. The best thing you can do is to ensure that you don’t apply too much pressure when applying the tape to your surface, as this can cause the adhesive to seep through the paper backing and make contact with the paint or varnish underneath. If this happens, clean off any excess adhesive immediately with some rubbing alcohol before it has a chance to dry on your surface and create a permanent bond there.

4. Be sure to remove all of the old adhesive from your surface before applying new tape

Is 3M Auto Tape Waterproof?

3M Auto Tape waterproof

3M Auto Tape is water-resistant, but it is not waterproof. There may be a few situations where the tape would hold up if left in contact with water for a long period of time. This is because there are so many variables involved when waterproofing products (temperature, humidity, etc.).

It is waterproof and meant to be used on boats or cars that will get wet. It sticks well to irregular surfaces like fiberglass or aluminum. It can also be used to repair holes in rubber boats or inflatable kayaks.

How do You Use 3M Double Sided Tape on a Car?

3M Scotch auto tape adhered well to most surfaces, including painted and unpainted car surfaces. However, it didn’t stick as well to rubber as it did to other surfaces.

The National Automotive Technicians Association recommends 3M Scotch auto tape for wrapping wires around their posts in your car. It can also be used to secure wiring under a hood or bumper.

It works on both plastic and metal posts and should not be used on painted surfaces because it is not waterproof.

What is 3M Tape Used for?

The name “3M” is an abbreviation for the company’s original full name, “Minnesota Mining & Manufacturing Co.” The company makes a wide variety of products, including abrasives, adhesives, laminates, specialty materials, safety and security products, medical products, office products, and electronic materials.

They are known for Scotch brand transparent adhesive tape. Anything you might need to hold down or keep secure.

3M tapes are widely used for heavy-duty industrial and automotive applications. 3M tapes and 3M command strips can be used to fix and protect auto paint jobs, headlights, bumpers, mirrors, door panels, and windows.

 Taping in the automotive industry is a common practice used to hold body parts together in place. The strength of 3M tape is usually higher than that of the bonding materials used on car frames and thus it saves time and material during manufacturing processes.

 3M tape is also used in military applications as it has high tensile strength when subjected to weather conditions such as rain, snow or extreme heat.

 3M tape performs well even under extreme conditions and thus is ideal for use in automobiles. However, before applying 3M tape to auto body parts try to clean these parts thoroughly to remove all grease or dirt particles because these particles will reduce bonding strength between the top coat of paint and the tape.

 Examine the surface where you will apply 3M Command strips carefully because if your car’s surface is too rough the adhesive won’t adhere properly.

If you have any doubts about the suitability of a particular area for taping, then test it with a small piece of tape first before securing a big piece of it with the full strip.

What Adhesive is Safe for Car Paint?

Tape used on car paint should be applied carefully and the surface must be clean and free of wax or any other contamination.

A minor scratch will not cause damage to your vehicle, but you may want to avoid applying tape that might cause a problem. These types of products are only as good as the person using them.

There is no adhesive that will damage vehicle paint due to the application of an adhesive-backed product such as 3M’s automotive fasteners and adhesives.

The key to the proper application of these products is allowing adequate time for the adhesive to “cure.” This means that the chemical reaction that takes place when the adhesive cures to a surface take some time to complete.

The glue bond formed between the adhesive and the paint surface should last for years, with proper care in the removal of the fastener or decoration.

Will 3M Command Strips Damage Car Paint?

Will 3M Command strips damage car paint

The 3M Command strips are intended to be attached to the inside of your car doors and, once secured, they can support more than 10 pounds.

3M Auto Tape was designed specifically for automotive use, so you can rest assured that it will hold up to the elements and other extreme conditions.


Because 3M auto tape is a vinyl-based adhesive, it is considered to be more durable than other adhesives. While 3M command strips include a plastic component, the strips themselves are plastic-free and sewn together.

This is great for those who worry about using metal with vehicle paint or any other delicate surfaces.
