The Best Double-Sided Butyl Tape for a Secure Fix
If you want to keep two surfaces stuck together and don’t want to get your hands dirty, butyl tape is the best option. We’ve spent more than 20 hours researching and testing double-sided butyl tape, and we found that the products we tested are the best for most projects. They’re easy to apply and remove, and they have the best adhere-to-almost-anything adhesion of any double-sided tape we tested.

The Approach We Took for Testing
We tested the tape on a range of surfaces, including wood, concrete, stone, ceramic tile, metal, and glass. And we used each tape at least a dozen times (more than 25 total) so we could become familiar with how it applied and how easy it was to peel off. We also checked the thickness of the tape, making sure that it was easy to cut cleanly and that the thickness didn’t distort the flatness of the materials we stuck it to.
For our double-sided tapes, we used each one at least eight times (more than 15 total) to see how well we could apply it to vertical or overhead surfaces (like hanging a curtain rod or pictures on a wall), and how easy it was to remove.
We also tested each tape for its ability to stick to materials other than its specified ones. Sometimes I’ve run into this problem: You pick up a tape whose packaging says it’s great for plastic, say, but then you try it on wood, and it doesn’t stick well.
We also ran each tape through a light abrasion test: We rubbed it on each material at least three times with a piece of medium-coarse sandpaper—enough to remove the top coat of the butyl adhesive but not enough to damage the underlying surface—and then checked how well it stuck afterward.
For our acrylic tapes, we tested their ability to stick under water using a standard wet-tape test. Each tape was applied to a sheet of fiberglass insulation, which was then submerged in a fish tank for about 20 minutes. We checked several times for bubbles that would indicate that the tape had come off the insulation and fallen into the water.
For our clear-drying tapes, we applied them to each material and waited for them to dry. Then we peeled them off and checked for any residue or damage left behind, as well as for signs of delamination—when the materials that have been stuck together separate later on.

Why Should You Invest in It
The GSSI Butyl Tape is the best sealant tape we tested. It’s easy to apply, and it forms a strong, watertight seal on almost any surface. It’s also easy to trim with a blunt tool, and it’s available in several lengths.
The tape seals quickly and cleanly, and it provides strong adhesion thanks to its butyl (rather than simple pressure-sensitive) adhesive. It does not discolor surfaces over time, either. Because it’s butyl, the tape will stick to a wide variety of surface materials.
The tape does require temperatures of at least 40°F (4°C) for proper adhesion, so we recommend that you apply it in warm, dry conditions. You can buy a 50-foot (15.2-meter) roll or a 400-foot (122.2-meter) roll of this tape online.

Why Should You Invest in It
The clear winner in our testing, the Butyl Tape is a double-sided tape that’s formulated with butyl, a rubbery polymer that’s similar to the material used in windshield-wiper blades. With a two-inch width, it’s wide enough to span most seams and gaps, and the tape’s high butyl content and strong adhesive mass make it an excellent choice for sealing troublesome leakage and holding vapor and moisture barriers in place to most surfaces.
The Butyl Tape works with most adhesives and sealants, and it will not bleed or stain materials. It’s also fairly weather resistant, with a temperature installation tolerance in both extreme cold (0°F) and high temperatures (300°F). It can be exposed to UV light for six months without issue.
It’s not the cheapest tape out there, but it’s still inexpensive, and we’d rather spend a little more for a tape that works well for a variety of projects than for one that doesn’t.

Why Should You Invest in It
Our pick, the Scotch 3M Double-Sided Butyl Tape, is a sturdy, versatile, and reliable tape that’s the best choice for most people. It sticks well to smooth and rough, clean and dirty, and even curved and uneven surfaces, including glass, metal, tile, marble, and wood.
It’s strong enough to hold up moderately heavy objects, like a desktop computer, and even more-massive objects, like a car registration plate. It’s also easy to remove and leaves very little sticky residue behind.
Compared with other tapes we tested, this one has the best balance of all the desirable traits: It’s easy to use, cuts easily, and doesn’t leave a mess.
The Scotch 3M tape is also the only tape we tested that comes with a white (instead of red) backing on the adhesive layer to help you peel off the tape’s protective layer.
You can also buy additional adhesive layers for the tape, as well as an adhesion promoter, to use if you’re applying the tape to an especially rough or porous surface.
Farm Plastic Supply Double Sided Butyl Tape – 1.25″ x 75′ – Black
Why Should You Invest in It
The Farm Plastic Supply Double Sided Butyl Tape is a reliable pick for most projects. It works on multiple surfaces, including wood, plastic, and metal, and it is one of the longest-lasting tapes we tested.
In addition, its adhesive is made from butyl, which is one of the strongest adhesives available on tape.
We think most people will prefer the more noticeable black option over the clear tape, which is the same width but is only half as long.

Why Should You Invest in It
We found that the Eternabond DoubleStick tape was the best option for most people working on a do-it-yourself project. It’s a double-sided butyl tape that’s sticky on both sides, so it’s easy to apply, and it’s widely available at hardware stores.
It bonds to a variety of different surfaces, including most types of roofing membranes, steel, aluminum, wood, and other plastics, as well as brick, concrete, and stone. And it’s self-sealing, so it doesn’t need to be sandwiched between two layers of material.
We found this tape to be the easiest to use of all the double-sided tapes we tested. The instructions are simple, and you don’t have to worry about cleanup.
The DoubleStick tape was also the only double-sided tape we tested that didn’t pull the paint off of our test surface (a brick wall) or leave a sticky residue.
Don’t Buy Before Considering These Factors
We researched and tested dozens of double-sided foam tapes. These are the best we’ve found for most repair and DIY applications.
Our criteria are as follows:
Adhesion
The tape should stick well to a variety of surfaces, whether they’re wood, drywall, concrete, or plastic. It should also stay firmly attached after its adhesive cures.
Stability
The tape should not curl up on itself or wrinkle when you try to peel it off a surface (this is especially important in tight spaces). The tape should also resist stretching or shifting under stress.
Stretch
This is mostly a concern with cloth-backed tape. The material should stretch slightly without tearing so that it conforms to curves and irregular shapes.
