Like duct tape in strength and adhesion, gaffer tape is more resistant to heat and easier to remove without leaving behind a sticky residue. Moisture-resistant drywall tape is a good choice for the bathroom, kitchen, and other rooms subjected to high levels of moisture and humidity. It isn’t waterproof, but it uses water to become more malleable and adhesive, allowing the tape to properly fill the gaps between two drywall pieces and eliminating the indented look that can come from drywall compounds. Therefore, it can work in situations where minimal moisture is involved but not in an environment where large amounts of liquid are involved.Įlectrical tapes are better suited for minor DIY electrical tasks such as repairing or joining small cables. Instead, most electrical tapes have a specific weather and water resistance level. Because this adhesive would likely lose its properties when wet, waterproof electrical tape is simply not practical nor possible. Electrical TapeĪlthough very stretchy and elastic, electrical tape is not waterproof. Because it is more temperature-sensitive, it also can lose its adhesiveness in the extreme cold. It is also thinner than your average rubberized tape, making it a bit less durable. However, depending on the size of the project, this bond can take some time to form, even up to 24 hours until it is sealed. Made from cured silicone rubber, silicone tape typically contains a thin layer of silicone gel to make the product self-fusing, forming a permanent bond around whatever it is applied to. These coatings can also leave behind some residues that can be tough to get rid of.ĭuct tape is also not very durable and will degrade when used in adverse conditions compared to most specialized tapes. However, while it is easy to use, it does not provide any real water resistance, so it needs to be coated with another substance to be truly effective on wet surfaces. It is covered with polyethylene resin coating, making the tape waterproof. It’s also often a more affordable option than acrylic or silicone tape! Check out this buying guide on how to find the right materials for your deck project! Duct Tapeĭuct tape is a strong tape made of cloth construction and is a common fixer around the house and in many industries like HVAC and automotive. In addition, it is a thick adhesive with high tensile strength making it optimal for deck building since it won’t break when stretched. Butyl is a flashing tape that holds water out, seals around decking screws and fasteners, and is impermeable to air. The flexibility bonds work well when moisture is a factor, such as creating a flex seal for an outdoor deck. Because it is UV resistant, less temperature sensitive, and maintains adhesion at lower temperatures than natural rubber, butyl is an excellent solution for outdoor, waterproof tape.īutyl tape adheres to most surfaces instantly because it conforms to the material, making it an excellent repair tape for various situations around the house. Trex Protect Butyl Tapeīutyl tape is a solvent-based rubber adhesive developed to augment traditional rubber adhesives. When working on outdoor projects, you want to be sure that you can ensure the lifetime of your investment by reinforcing it with strong adhesive tape. Durability:Īlways pick heavy-duty adhesive tape with a reliable warranty. Both butyl and silicone rubber are great outdoor waterproof tapes for sealing up a leak in the roof or patching a hole in a boat. Butyl tape is great because it adheres to a wide variety of surfaces, such as glass, metal, plastic, and wood. It’s also crucial that you can use the tape you choose for different purposes. It will also need to create a tight, waterproof seal with the surface of your deck to prevent running water from getting in and peeling away the tape. For example, if you’re working on your outdoor deck, you’ll want a tape that can withstand the elements like rain, snow, and low temperatures for an extended period of time. You’ll want to go with a waterproof tape that will meet your project’s adhesive requirements of strength. Still, outdoor use variables like extreme temperature changes, direct sunlight exposure, and physical stress can decrease its lifespan. Waterproof tapes tend to last for about five years before the adhesive starts to break down. What to Look for in a Waterproof Tape Adhesiveness:Ĭhoose your waterproof tape based on the strength and effectiveness of the adhesive. Check out the guide below to learn why butyl seal tape beats the rest for tough jobs. With so many options to choose from, finding the right waterproof tape for your project can be a difficult task.
