Some products are worth having on hand, just in case you need to use them.

And having them on hand can save you a trip to your local hardware store. Zip ties and duct tape are everyday items. However, we suggest you add butyl tape to that list.

Today, we’ll share everything you need to know about butyl tape and its many uses. Let’s get started!

What Is Butyl Tape?

Butyl tape is an adhesive material created in a laboratory. Unlike natural rubber adhesives, butyl tape is more resistant to changing temperatures, making it ideal for various outside applications. 

The tape works best as a sealant between joints and does a fantastic job as an additional barrier to keep moisture out.

Many manufacturers lay a layer anywhere they place screws or with a potential for water penetration. 

And you can commonly find it where walls come together and under roof fixtures. These are some of the most common spots for water damage, especially in RVs.

What Will Butyl Tape Stick To?

Butyl tape is incredibly versatile when it comes to surfaces it sticks to. It’s capable of adhering to rubber, glass, plastic, and metal. Because of its unique design and characteristics, it’s also incredibly resistant to temperature changes. 

If you live in a climate that experiences frequent temperature changes, this is one product you’ll want to keep readily available for your projects. 

This is especially true if you want to keep moisture and other potentially damaging materials out of a specific space.

How Long Does Butyl Tape Last?

The printed shelf life for butyl tape is typically five years from its manufacture date. However, in many instances, it can last for 20 or 30 years in some applications. It’s one product that is extremely resilient and experiences minimal degradation. 

Keep it away from harsh chemicals like gasoline and turpentine, and you’ll likely get a couple of decades of use from your butyl tape. It’s one of the most resilient and dependable types of tape available on the market.

Can You Remove Butyl Tape?

Because butyl tape is incredibly good at doing its job, it’s not always the easiest material to remove. You’ll need to use a generous amount of solvent, like paint thinner, to remove it from an area.

It can be incredibly stubborn. In these instances, it can help to grab a heat gun or hair dryer to heat the tape and use a plastic scraper to get under the adhesive. 

Just be careful how much heat you apply to the area and that you don’t use too much force with your scraping. Either of these actions could cause serious and extensive damage to the surface.

What Is Butyl Tape Used For?

As we’ve mentioned, there’s no shortage of applications for using butyl tape. It’s an incredibly versatile material that can be helpful in several ways.

Let’s look at a handful of the most common applications.

RV Repairs and Maintenance

If you’ve ever owned an RV, you know that moisture and water can quickly cause tremendous damage. If left unaddressed, water damage can quickly cause floors to rot and dangerous molds to grow inside an RV.

As a result, many repairs and maintenance projects use butyl tape to minimize risks from moisture. Some camper manufacturers even install long sections of it along the seams to keep water from penetrating the rig.

The tape reduces the chances of water getting in through screw holes in a camper. If you’ve looked at an RV, hundreds, possibly even thousands of screws hold it together. Water penetrating any of these holes can cause serious and expensive damage.

Seal Windows

Whether it’s moisture, hot air, or a cold breeze, you want to eliminate any gaps in your windows. Butyl tape works great as it is easy to form and is durable and resistant to constant weather changes.

If you’re tired of feeling drafts blowing in from your windows, consider sealing them with this tape when installing them. By keeping your windows sealed, you make it easier for you to control the temperature in your living space.

Residential Repairs

Butyl tape also works perfectly for some residential repairs and projects, such as sealing up HVAC ducts, sealant for a metal roof or siding, and assisting with vapor barriers in crawl spaces.

If you worry about moisture penetrating an area, use this as a part of your defense plan.

Marine Applications

As we’ve mentioned, butyl tape is fantastic at protecting against moisture. We can’t think of a place where it’s more important to keep water out than a boat. They say loose lips sink ships, but holes in boats do too. 

However, sometimes you’ll want to attach rigging and other accessories to your boat, and you may need to drill a hole to make it happen. 

Placing a layer of tape under any rigging or accessories can help reduce the chances of water penetrating a boat.

For it to be effective, you must use it on any fasteners you add. Give it a day or two, and then cut off any excess materials that stick out from the fasteners.

Butyl Tape Can Save the Day

Butyl tape is one of the most effective and versatile products. It’s easy to see why you should have it readily available to assist you with any projects you might have around the house, with your RV, or in many other instances. 

It’s best to have it available and rarely need it than to need some and not have it. You never know when it could come to your rescue and save the day!
