Product Description

By entering your model number, you can make sure that this fits.
RV AND MOBILE REPAIR ON A PROFESSIONAL LEVEL. In terms of appearance and functionality, the XFasten Butyl Tape can easily mimic how professionals seal their roofs or windows. Never be afraid of repairing an RV, mobile home, boat, fiberglass or galvanized metal roof, or EDPM roof rubber.
THE FINISH IS ELASTIC, SMOOTH, CORROSION-RESISTANT, AND WATER-TIGHT. Installs without gaps and is capable of reliably blocking moisture, vapor, corrosive chemicals, and other leaks. Painting over the surface will create a seamless, neat, and water-tight installation area.
EASILY INSTALLS ON TIGHT CORNERS AND OTHER UNIQUE PATTERNS. It can be quickly and easily installed on tight corners, unusual curves, textured, uneven, and jagged surfaces.
EASY TO INSTALL AND HAS A LONG SHELF LIFE. Because of its wide operating temperature range, the XFasten Butyl Tape has a long shelf life and resists melting into a gooey slob during transportation or storage, unlike most putty tapes.
COMPATIBLE WITH A VARIETY OF SURFACE TYPES. Rubber roofing, galvanized metal, frosted fiberglass, wood, textile, plastic, aluminum, and other common RV, home, automobile, and boat surfaces are all suitable for use.

Questions & Answers

Is it sticky from both sides?

Yes, everything is putty-like and sticky.

What can I do to remove it from around my windows? It's a disaster! ?

Roll a small piece of butyl tape into a ball first thing in the morning, before the sun softens it. Remove any excess butyl from the window with the butyl ball. Keep the ball in case you need to seal something in the future. Butyl dissolves in oil if that doesn't work. On a paper towel, any kind of oil will dissolve it. After that, clean the window with dish soap to remove the oil.

Is there a distinction in performance between white, black, and grey? What makes white so expensive in comparison to other colors?

In the summer, white is in higher demand because it does not absorb as much heat. Black cracks more easily, but grey holds up well as well.

As far as I can tell, Aluminum will corrode if you use new pressure-treated wood. Is it possible to use this tape as a corrosion preventative between the two?

Your previous question, Eric, has been read by us. Thank you so much for taking the time to respond. a new question To reiterate our response, the XFasten Butyl Tape can be used as a corrosion barrier between the treated lumber and the aluminum. Please keep in mind that the XFasten Butyl Seal Tape is similar to putty but has a clay-like consistency. Because it's still putty, it'll work as a spacer and sealant between two surfaces, but it'll stay on the surface for a longer period of time than usual. For a long-lasting sealant, the XFasten Butyl Tape is ideal. If you have any additional questions, please do not hesitate to contact us. Thank you very much!

Supplier who knows what he's talking about
5/5

This product came in handy when I needed to seal some seams in my RV. It was ideal for this project. The original order arrived with a ripped package and missing product; I contacted Apipema, the product's supplier, about the missing product, and despite the fact that it was not their fault, Apipema was gracious enough to send me a replacement. There is no cost. This company deserves praise for their excellent service, and I will gladly order from them again in the future because they stand behind their products. For your needs, I strongly suggest Apipema.

Material of high quality
5/5

Simple to work with. I am very pleased with my recent DIY Maxx Air fan installation using this Butyl tape product. br>br>The release strip is well waxed and does not stick like other products you see on YouTube. br>br>I was also blown away by its tack strength. br>br>There is enough tape for the installation, with some left over for a future product. br>br>Because the product is pliable, I recommend keeping it flat when not in use. br>br>In the future, I will purchase this item.

Good things tend to stay where you want them to
5/5

It's a good product for keeping water out of sinks and pipes. It's preferable to a dried-up can of something. It can also be used to seal air gaps in plastic, such as between the door panels of a car. It comes smashed, so the backing is a little difficult to remove, but it's putty, so it's soft. It's not a problem if you come across this; simply re-enter the information. It can be shaped to fit your needs.

Although it is a good sealant, it becomes gooey when exposed to the sun for long periods of time
5/5

The roll of seal tape reminds me of putty that has been flattened into a make-shift mask. Shift roll is a unique product to store because it appears to be a little messy. In a cool storage closet, I recommend storing ziplock bags. br>The application of the putty-like substance Playing with putty with your fingers only gets you so far in tight spots like the gap between the apartment front door frame and the base threshold. Yes, the seat tape putty works well and can be painted. When the front door is exposed to long periods of full sunlight in the summer, it becomes a bit gooey due to its poor heat resistance. The indoor portion of the seal putty job, on the other hand, is holding up well and hasn't melted. br>For the money, it's a good product; it keeps the elements out (as well as outdoor insects like spiders), but it could use some more manufacturer development to improve heat resistance in full sun exposure.

Excellent Product - The smell of shipping stinks
4/5

This stuff is soft and squishy, and it comes on a reel with wax paper separating the layers. On my last order, the reel was thrown in with another box, and by the time it arrived, the reel was square, and the product had been squeezed out of one side of the first nine layers. It was impossible to use any of this. I sent it back and placed an order for two more reels. When I opened the box and saw some padding, I was pleasantly surprised. Then I noticed that neither of the reels in the box would lay flat. They were oriented in such a way that the first five layers on both reels are now of varying thickness. br>br>As I previously stated, this is a fantastic product; however, order twice as much as you think you'll need because the shipping process will cause you to lose a significant amount of product. If you can wait until winter, the material will harden in the cold and may be able to withstand shipping.

The product arrived squished in its packaging
3/5

This was recommended for use on the outside of my camper van in any application. It was sent, but the box had been squished, and half of the roll had already been smudged. It took a long time to unroll this putty-like material. Amazon sent me another, and it wasn't in plastic, so it wasn't smushed, but it had already started hardening. Instead, I used lap sealant and weather stripping, and I removed some of it to install the screws. It appears to be in good shape. I just turned it off and gave it a low rating because of how it arrived.

The adhesion is excellent
5/5

This tape was simple to use and had excellent adhesion to fiberglass, metal, and brick. I used wax paper for any fine adjustments because it sticks to almost anything (gloves, skin, tools, etc. ). Similar tapes have always been a disaster in my experience. This is not the case! Even with my inexperienced hands, I was able to apply this tape quickly and easily. good luck.

It's a cinch to use
5/5

From cleats to light lenses, I've used it to store a variety of items on my boat. It takes a little fiddling because it tends to stick to both your fingers and the object you're trying to stick it to. Before you apply it, I recommend cutting off the length you need with sharp scissors. Also, before installing screws, cut narrow strips to wrap around them.
