Buying Guide


Water-resistant and waterproof tapes come in various different varieties that are varied by their purpose, durability, and texture.

Waterproof reflective tape is commonly used to identify mailboxes, driveways, and trash cans so they are easy to see at night or in inclement weather. Reflective tape also can assist clearly highlight lanes and risky places in the workshop or be used on a boat to help make it more apparent to other boats.

As mentioned, drywall compound can leave an indented appearance when applied to drywall, but utilizing drywall tape prevents this from happening. While drywall compound is not waterproof, water makes it more flexible and adhesive. Moisture-resistant drywall tape is a wonderful solution for the bathroom, kitchen, and any other rooms prone to high levels of moisture and humidity.

Nonslip waterproof tape includes a textured backing to help prevent slipping. A boat's floor, a house's front steps or a deck/deck/patio patio's can all benefit from the addition of this product. The textured backing on the tape helps to avoid sliding.

The strength and adherence of gaffer tape are comparable to those of duct tape, although the latter is more heat resistant and leaves no sticky residue behind when removed. However, gaffer tape is created with a hefty cotton cloth backing that is normally simply water resistant, not waterproof. Also, waterproof gaffer tape is a speciality product that could be difficult to locate.

Although duct tape is likewise made of cotton, the polyethylene resin coating on the cloth ensures that it is impermeable. Heating and air-conditioning (HVAC) technicians use duct tape, as do mechanics and hotel staff for securing carpets and padding. It's also widely used in the home.


The durability, water resistance, adhesive strength, and method of application of waterproof tape can all be affected by the material used in its production, which includes cloth, plastic, and rubber.

Cloth often refers to a cotton tape backing that is durable when applied but also simple to break from the roll. Gaffer tape and duct tape can be torn apart with ease because to this feature. However, cloth doesn’t have any major water resistance, therefore it needs to be coated with another substance to be useful in wet situations.

Waterproof backings for common tape types, such as duct tape and reflective tape, can be found in plastics such as polyethylene, polyethylene terephthalate, polyvinyl chloride, and polymethyl methacrylate. Plastic is flexible and robust, allowing the tape to stretch without breaking. The adhesives in plastic, on the other hand, can be very strong and leave behind residues that are very difficult to clean up.

Waterproof tape can be made from either butyl rubber or silicone rubber. To repair an above-ground pool's side or patch up a boat, this type of tape is commonly used for outdoor repairs including sealing up roof leaks or patching up holes. Some can even go on while underwater.

Adhesive Strength

The strength and effectiveness of the adhesive are important considerations when choosing a waterproof tape. On average, a waterproof tape can remain functional for up to 5 years before the adhesive begins to break down, while circumstances including high temperature changes, physical stress, and exposure to direct sunlight might lower this length of effectiveness.

Look for a waterproof tape option that meets the project’s criteria for adhesive strength. Temporarily anchoring cables with gaffer tape requires far less adhesive strength and resistance than adding nonslip tape to a regularly utilized portion of the house, like the front steps. Tape meant to block leaks needs to be able to make a tight, watertight bond with the metal, wood, or plastic surface to prevent running water from seeping in and gradually peeling away the tape.

Adhesive strength

Weather, physical stress, and exposure to direct sunlight can all degrade the adhesive in waterproof tape during the course of the tape's 5-year lifespan.

It's critical that you pick the correct adhesive strength for your job.

Tape goods developed for fixing leaks need to be exceptionally adhesive and they can be more difficult to apply because the adhesive is more viscous in order to produce a bond that completely seals the hole or break.

They might not be suitable to use in a tapegun for example.

Once this tape is in place, it might be difficult to remove without leaving a sticky residue behind.


Color can occasionally be a significant characteristic for particular applications like visibly cordoning off a hazardous area or highlighting a hard-to-see object, such a mailbox or garage door.

In order to distinguish between different types of electrical circuits, electricians may use colorful tape.

Waterproof tape in a neutral color blends in seamlessly with the rest of the decor, making it an excellent choice for interior design projects.

Ease of Use

The greatest approach to guarantee that the project will be done with the least amount of complications is to select the suitable product for a given purpose. Waterproof tape goods made for general-purpose repairs around the house normally can peel, cut, and apply without much issue, but these materials could have a hard time adequately adhering to outside surfaces.

In order to produce a bond that completely closes the hole or fracture, tape products designed to repair leaks or withstand hot and cold temperature extremes use stronger adhesives and are therefore more difficult to apply. However, removing this tape without leaving a sticky residue is difficult once it has been applied.


Can I stop leaking with waterproof tape?

Waterproof tape developed for sealing cracks and holes is a fantastic solution to halt a leak. Repairing a boat is made easier by the availability of products that may be used on submerged surfaces.

Is waterproof tape good for outdoor use?
