Buying guide

To purchase the best waterproof tapes among the massive number of brands and models in the market at present, it is indispensable for you to learn about the critical characteristics of waterproof tapes that determine their quality. 

Depending on your use, assess a waterproof tape depending on the following 10 key factors:

1. Waterproofing property

It is needless to say that the foremost feature of a waterproof tape is how well it fights against the infiltration of water. As a result, you must check this property of the product first of all. 

It is important that the adhesive face of the tape can cling to a wet surface but the other one does not get wet. To achieve the optimal waterproofing capability, the backing of the tape must be either vinyl or rubber.

2. Adhesive

Your waterproof tape had better feature a strong adhesive to fix patch holes, fix faults, mount things, and so on efficiently in the long run. If they are not clingy enough, time and external impacts will soon pull them out from surfaces.

Nonetheless, under rare circumstances, you may not want the tape to be too sticky if you need to remove them later. For example, if you use a medical tape that is too adherent to wrap your wound, you will suffer pain when you unwrap it.

3. Tensile Strength

The high chances are that the tape might have to handle heavy load or pressure. Consequently, a decent tensile strength is in need for long-lasting performance.

For instance, if you use the tape to package items tightly, you must stretch it tensely and keep it in a high tension state.

4. Ease of Use

We have encountered numerous complicated and annoying tapes that drive us crazy to use and remove. Therefore, a good tape should be easy to handle, remove, cut, etc.

5. Electrical Use

If you want to use a tape for electrical applications, remember to inspect it carefully and make sure that it is created for this purpose. Not all random tapes can endure high voltage and extreme temperatures in electrical lines.

6. Temperature Range

With different ingredients, every tape has a particular working temperature limit. Outside that range, the tape will not work or will deteriorate quickly.

For example, if the tape cannot work in the temperature higher than 50 degrees Celsius, you should not use it on electrical lines or outdoor.

On the other hand, if a silicone rubber self fusing tape cannot work in too low temperatures, do not use it in a cold storage.

7. Marking

Some people may overlook this, but it may be crucial to others. Whatsoever, a premium waterproof tape ought not to leave any mark on the skin of users or surfaces of items.

8. Size

Think about what you would do with the tape before you pick a suitable size. Do you need a narrow or a wide tape? A thick or thinner one would do well?

If you are going to patch large holes on your car windows, you need a wide tape. Multiple tiny lines of tape will not only cost you a lot of time but also work ineffectively.

Vice versa, a massive tape would be redundant, wasting and unnecessary to seal a tiny hole on your garden hose.

If you need waterproof tapes for various uses, you may buy a medium-size one or several tapes with different dimensions.

9. Durability

Those waterproof tapes not only help you to fix things but also sometimes safeguard them. Hence, they should be tough and long-lasting.

The durability of a waterproof tape relates to a number of factors such as material, adhesive, tensile strength, size, temperature limits, and more.

It is easy to understand why a super thin waterproof tape selffusing silicone is easier to wear and tear than a thick silicone rubber self fusing one, although both of them are self fusing rubberized tapes.

10. Safety

You should check the ingredients of the tape and ensure that they are all safe for users, especially if you plan to use the tape to wrap your wound, patch your (drinking) hose, fix the electrical line, etc.

Toxic compounds like sulfates or phthalates can make you allergic or suffer from other negative effects. A common sign is that these harmful substances typically come with unpleasant odors.

Apart from the components, a tape’s design may affect its safety level. Tapes with rough edges are likely to scratch users and result in bruises. 

It is a good idea to buy products that are certified and approved by reputable organizations like ANSI, UIAA, so on.

FAQs

Answer: No, they are a bit different from each other. In fact, all duct tapes have the ability to resist water to a certain level. However, only a few duct tapes are specially formulated to be 100% waterproof.

Answer: Sadly, it is absolutely not. You should only use products that are assigned to be suitable for your electrical line (for example, the TradeGear TGX1BLACK Electrical Tape). 

Answer: Of course, this factor varies according to products. But on average, a premium waterproof tape is able to withstand the maximum temperature of up to 200 degrees Fahrenheit

Answer: Yes, it is possible. If a waterproof patch is heated for extended periods, it is likely to melt even within its temperature limit.

Answer: According to the activity rule of chemicals, all soluble substances will be dissolved in water and other liquids by forming hydrogen bonds. 

In waterproof tapes, manufacturers us vinyl or rubber as both the adhesive and a backing material to prevent any hydrogen bond with water. In this way, whether in the underwater environment or humid condition, waterproof tapes will not be affected.
