So what is butyl tape, and what are its uses? Read on to find out everything you need to know about this versatile material.

What is Butyl Tape?

Adhesives are either natural or synthetic and come in three different types: acrylic-based, silicone-based and rubber-based. Butyl tape is a synthetic rubber adhesive manufactured to upgrade natural rubber adhesives. Compared with its natural counterpart, butyl tape is less sensitive to varying temperatures and maintains its stickiness at lower temperatures than traditional rubber adhesives.

Butyl tapes are highly flexible, durable and waterproof, creating an airtight seal on whatever surface you use them on. These many valuable properties, plus its versatility, make butyl rubber tape a popular adhesive option.

Surface Compatibility

Butyl rubber is a heavy-duty adhesive that instantly adheres quickly and easily to most surfaces, even those like outside decks where moisture is a factor. Butyl tape is compatible with these surfaces:

• Glass

• Rubber roofing

• Metal Roofing

• Galvanised Metal

• Wood

• Aluminium

• Plastic

Butyl tape is easy to install and can withstand extreme weather conditions from heavy rainfall to summer heat, meaning you can use it seamlessly in and outside the house for an effective seal on any of the above surfaces.

Uses of Butyl Tape

Homeowners and industry professionals often view butyl tape as an all in one solution because of its multifunctionality. Follow on for a closer look at some of the primary uses of butyl tape.

Window Sealing

Butyl seal tape is much easier to work with than the traditional sealants used for windows, so many people prefer to use it. It is incredibly supple and easy to bend and manipulate to the shape of the surface you&#;re using it on, making it ideal for installation on oddly-shaped windows and window frames.

Small Household Repairs

Butyl tape is perfect for areas in the home where leaks and corrosion occur because it is waterproof and highly adhesive. Use butyl tapes for roofing repairs, leaking pipes, ventilation systems, etc.

Cars

Sometimes, cars cause problems at the least opportune times, so keeping a roll of butyl tape in your car for those unexpected issues can come in handy. You can use butyl tape for quick emergency car repairs like filling gaps on a firewall or fixing a sunroof.

Motor Homes

Similar to its use in cars, butyl tape can also be a saviour in a motor home! While butyl tape is generally slightly more expensive than the usual putty tape used for RVs, the extra few dollars spent is worthwhile for a tape that doesn&#;t dry out as fast, is much easier to work with and isn&#;t as messy. Butyl tape is excellent for sealing motor home skylights.

Boats

Butyl tape really is an all-rounder tape! It is perfect for use in the marine industry because of its strength, waterproof seal and compatibility with boat surfaces. Use butyl tape for boat hatches, portlights, and deck fittings.

How to Apply Butyl Tape

As with any adhesive, there are actions to ensure your project is adequately covered and protected. To properly install butyl tape, follow these simple steps.

1. Preparation

   . Around 2-3 hours before starting your project, put your butyl tape in the fridge. This tip is more a handy trick than a critical step, but chilled butyl tape is easier to work with and much more manageable.

2. Clean.

   The surface you&#;re applying your adhesive to should be spick and span, so ensure it&#;s completely free from dust and dirt prior to application. Once the surface is clean, make sure it&#;s dry before sticking down your butyl tape.

3. Peel

   . Carefully peel away a little of the backing from the butyl tape, then apply the first part to your surface. As you peel more backing away, stick the tape down, taking care not to touch the adhesive side &#; not only could this tape stick to your skin, oils from your hands can damage it.

4. Press

   . Eliminate gaps and air bubbles by running your fingers over the butyl tape, pressing it down and around all of the surface&#;s bumps and curves to ensure every bit of the tape is stuck down.

5. Layer

   . Repeat the actions above as many times as you see fit to layer the butyl tape. This step is another optional one, but it helps reinforce your project with extra strength, stability and water resistance.

6. Trim

   . Once you&#;re happy with the application, cut the butyl tape down to size with scissors. It would be best if you also trimmed any excess putty that has oozed out from the tape.

7. Cure

   . The longer you leave the tape to dry and cure before exposing it to harsh conditions, the better. Overnight is ideal, but 3-4 hours will suffice if you don&#;t have a full day.

Pros and Cons of Butyl Tape

There are benefits and disadvantages to using butyl tape, as with any materials and tools. Let&#;s start with the pros:

• It securely adheres to the vast majority of surfaces and materials

• Butyl tape is less temperature-sensitive than natural rubber

• It can withstand extreme weather

• It doesn&#;t dry out like other adhesives

• Butyl is usually cheaper than silicone or acrylic alternatives

• It provides an airtight and watertight seal

• Butyl tape is versatile &#; it has many application uses

Not even an all-rounder like butyl tape is perfect! Read on for some points to consider before buying and using this tape.

• Butyl tape is better than natural rubber but is occasionally affected by extreme temperatures

• Strong solvents like gasoline and turpentine can dissolve butyl tape because it&#;s solvent-based

• It&#;s challenging to stick butyl tape to rough, uneven surfaces

Tips and Tricks

Now that we know everything there is to know about butyl tape, read through these last couple of points to help you purchase and apply this diverse adhesive tape.

Buy Self-Adhesive Butyl Tape

If you&#;re wondering which tape should you buy, consider self-adhesive butyl tape. It&#;s much easier to install, meaning no fiddly application and less chance of getting yourself stuck.

Thickness

The thickness of the tape you buy is an important consideration. Too thin, and your tape won&#;t be as durable, but too thick, and it&#;ll be difficult to install.

Butyl Tape Wrapped Up

If you&#;re looking for tape covering all bases, butyl tape is excellent. Among its many uses, you can use butyl tape alongside Wakaflex to bond roofing and building materials together, and it is the perfect material for several home renovation projects. Its multifunctionality, affordability and reliability make it a firm favourite in the industry and having a roll laying around the house can prove really handy!

THE LATEST IN ROOFING

Sometimes you want an adhesive that&#;s modestly sticky and easily reversed&#;like a sticky note.  Other times, it needs to be darn near irreversible.  High-performance building contractors also need to consider adhesive tapes capable of withstanding temperature extremes and volatile moisture conditions; adhere to a wide variety of substrates; and tolerate the dust and dirt found on the surfaces of the building materials or the job site.  Is that acrylic or butyl? Silicon or rubber? Here&#;s what you need to know.

What Are the Types of Adhesives Used in Tape?

That said, there are four basic types of adhesives used in tape all of which differ in characteristics as well as cost.

Rubber: Adhesives that are based on natural or synthetic rubbers and formulated with tackifying resins, oils, and anti-oxidants. Rubber is often the most cost-effective adhesive and offers quick stick capability. Rubber adhesive is not recommended for high heat applications. It also does not perform well in colder temperatures, especially if it reaches below the freezing point of 32°Fahrenheit.

Butyl: A specialized rubber adhesive system, butyl was developed to augment traditional rubber adhesives because they are less temperature-sensitive and maintain their tackiness at much lower temperatures than natural rubber.  And while butyl sticks better to more substrates, butyl is also more expensive.

Acrylic:  Acrylic adhesives can be water-based, solvent-based, or &#;solid.&#; Water-based adhesives are the least expensive of the three and generally do not bond to as wide a variety of substrates as solvent-based ones. Solid acrylic adhesives can form the strongest adhesive bonds at a wide range of temperatures and even achieve adhesion to damp or wet substrates. Solid acrylic adhesives are also VOC-free, and the absence of any solvents means little to no embrittlement of the tapes over time. Both water- and solvent-based acrylics are similar in cost to butyl rubber tapes; however acrylic adhesives typically develop a stronger bond than the traditional Rubber adhesive and are able to take higher temperatures

Silicone: Formulated with Silicone polymers and the only adhesive that will bond well with silicone substrates. Silicone adhesives are relatively expensive and have a very low initial tack, but can withstand higher temperatures than both Rubber and Acrylic adhesive

So, which is the best fit for your application?  Well, for builders and professional contractors, it really comes down to butyl and acrylic. So let&#;s take a closer look at these two popular adhesive technologies.

What Is Butyl Tape, Exactly?

Butyl tape is an example of a synthetic rubber adhesive. It&#;s a solvent-based adhesive that is formulated in the lab instead of coming from a rubber tree. All types of rubber adhesive are thermoplastic, so exposure to high heat will soften the adhesive and impact its effectiveness. However, butyl adhesives are formulated to be less sensitive to temperature variations. They stay more flexible in cold weather and more stable in high temperatures than natural rubber adhesives. Because butyl tapes are extremely durable,  with have good flex properties, they are often used in applications where an airtight bond is required. In fact, most butyl tapes also come with a liner since the adhesive system is aggressive and forms a permanent bond to the surface it sticks to &#; even if that surface is itself!

When Are The Advantages of Butyl Tapes?  

Advantages:

High initial tack­&#;has a more aggressive hold on contact than acrylic adhesives

Has a high level of adhesion because it bonds to a huge variety of surfaces

Less expensive than acrylic adhesive

Impermeable to air

Waterproof so it works well in situations where water is a factor

Disadvantages:

Even though butyl adhesives are less sensitive to temperature variations they still cannot match the range or performance of acrylic adhesives.

Does not hold up over time to direct exposure to UV light or chemicals

Susceptible to oxidation and may darken or discolor

Ideal for:

Seaming and flashing windows and doors

Repairing leaks

What Is Acrylic Tape, Exactly?

Acrylic tapes are either water- or solvent-based. They are created by crosslinking monomers to create polymers with specific properties. Acrylic adhesives are naturally tacky so they don&#;t require as many additives during the manufacturing process as rubber adhesives. Offering a good balance of adhesion, shear and tack, tapes with acrylic adhesive systems are resistant to thermal and UV degradation. They can be used on many surfaces and perform in a much wider application temperature range &#; typically anywhere from -30°F to 300°F.  The only real downside is the cost; these tapes cost a bit more than the rubber or asphaltic tapes. Builders often use acrylic tapes to completely seal a home, creating an airtight envelope.

When Are The Advantages to Acrylic Tapes?

Advantages:

Offers superior durability and longevity on polar surfaces (i.e. metal, glass, and polycarbonates)

Will not break down when exposed to extreme temperatures, UV light, chemicals or oxidation

Color stable and resistant to aging (will remain clear and not yellow)

Have a high level of cohesion (ability to stick to itself)

Are considered &#;greener&#; or more environmentally friendly in that do not off-gas or pollute landfills

Disadvantages:

Needs time (usually 24-72 hours) to fully set

Poor adhesion to low energy or non-polar surfaces

Impermeable to air only on polar surfaces

More expensive than butyl adhesives

Ideal for:

Seaming vapor barriers, house wraps, and rigid foam insulation

As always, the adhesive compound is just one factor that should be taken into account when selecting the right tape for the right application.  Characteristics like backing, strength, and permeability, as well as environmental conditions and substrate, are a few other factors that can impact the job, and ultimately, its success.
