Best Liquid Electrical Tape

If you are a DIYer or electrician, you will need electrical tape for insulating cut wires when doing home electrical repair or fresh installation. But that is not a problem because you can do it with conventional electrical tapes. What if you are performing the same task in tight and hard-to-rich spaces? The usual taping becomes cumbersome, and that is when you need liquid electrical tapes.

As the name implies, liquid electrical tape is in the liquid state, unlike the adhesive paper tape roll. The standout benefit of using this electrical tape is it can be applied on tight spaces easily but can also be used practically anywhere you have a wire joint or physical wire connections.

Liquid electrical tape measures are adhesive and waterproof. That means you can use them in controlling corrosions and insulating bare electrical wire. However, there is a challenge when you go to the market to buy them.

Different liquid electrical tape brands and models exist. These many options are overwhelming if you don’t know the properties or features to look for. To curb the problem, we have prepared a review of the best liquid electrical tapes and provided a buying guide to help you make an informed decision.

What to Consider Buying A Liquid Electrical Tape

Consider the following factors if you are looking for the best liquid electrical tape to buy:

1. Capacity

Liquid electrical tapes come in small cans, typically 4 oz. But you can find others from 1-6 oz. The amount you buy should match your needs because you don’t want to deplete them halfway before the work is done.

2. Material

Most liquid electrical tapes are made of rubber bases, but you can find others with elastomer or vinyl bases. Regardless, check the final result after application. You need a product that maintains flexibility after being fully cured if you don’t want them to crack or peel off. It will ensure longevity.

3. Color

Like conventional electrical tape, liquid ones are available in different colors. As an electrician or DIYer, you understand the importance of color coding in electrical wiring. So, you may need to match the liquid tape color with the wire color for uniformity.

4. Resilience

Liquid electrical tapes are not only for sealing stripped electrical wires or connections. They should also protect them from elements, such as water, UV light, dust, debris, heat, and many others. So, the product of choice should resist them to avoid degradation or corrosion.

5. Compatibility Material

Consider what you want to use the liquid electric tape for. Some are only compatible with certain surfaces and may not adhere to others. When buying a new liquid electrical tape, the best product should work on multiple materials, such as wood, plastic, rubber, vinyl, fiberglass, metal, or composite. This property makes it versatile.

6. Drying and Curing Time

How fast does liquid electrical tape dry out? Most products will take about 24 hours to completely dry out, but you can find other options. While you can get carried away by the fast-drying time, consider the liquid state of the product. Ensure it flows smoothly and is easy to apply.

7. Price Tag

Liquid electrical tapes are affordable products. So, you don’t save much by going for the cheapest option. You can consider what gives you the best value for money.


Q: Is liquid electrical tape waterproof?

A: Yes. The whole reason for applying liquid electrical tape is to form an airtight and waterproof seal around the connection points or stripped conductors. That is the only way to protect them from corrosion and other elements causing degradation.

Q: Liquid electrical tape vs. heat shrink, what is the difference?

A: Both liquid electrical tapes and heat shrinks offer a more durable seal or insulation around conductors than conventional electrical tapes. However, the two are applied differently and exist in different forms. A heat shrink is solid and requires heat. The heat melts it and forms tight insulation around the conductor after cooling.

On the other hand, the liquid electrical tape does not require heat and exists in a liquid state. After application, it cures under normal conditions and hardens around the conductor.

Q: What is the difference between liquid electrical tape and regular electrical tape?

A: The main difference is their state. As the name suggests, liquid electrical tape is in liquid form but dries out into a flexible vinyl. On the other hand, conventional electrical tape is solid and adhesive on one side that wraps around the connection joints or stripped conductors. Regarding longevity, liquid electrical tapes carry the day.

Q: How to use liquid electrical tape?

A: Using electrical tape is straightforward. Some come with a brush cap applicator for applying the liquid on the electrical conductors with damaged insulations. But before using it, you should stir it and ensure it is of the right thickness. Most liquid electrical tapes require only one application, but adding a second coat after five minutes to increase insulation thickness is possible.

Best Liquid Electrical Tapes: Recommendations

Gardner Bender LTB-400 liquid electrical tape is the best choice. It is cost-effective and reliable in protecting conductors from weather elements. It also dries relatively fast, taking only 24 hours to fully cure.

The second recommendation is the Star Brite liquid electrical tape. Like the first choice, this product also cures in about 24 hours and effectively protects conductors from corrosion and UV light. It, however, lasts longer and is compatible with multiple surfaces.

Permatex 85120-6PK liquid electrical tape is the last recommendation but is equally one of the best products. It is dust, water, chemical, and rust-resistant and works on multiple surfaces.

You can also choose any of the products reviewed in this post. They were keenly selected and should effectively function as intended.
