To see the best results for butyl joist tape, you must apply a thin coating of this material to each board. It’s also important that you use the product in conjunction with any decking sealant.


When your deck is damp, the ground underneath your deck loses a lot of moisture. This means that when it rains, the water seeps into the joists and makes them weak. This can cause the joists to start to rot and lead to water damage. One of the benefits of butyl joist tape is that it can help you create a watertight seal that will prevent water from leaking. This can be vital when it comes to the longevity of your deck.

You can also use butyl joist tape to help prevent damage to your decking when it is the hottest time of the year.

You can apply butyl joist tape by making several parallel strips and combining them to make one long strip. The tape can then be stretched over the joists and secured with the included vinyl knot. Make sure that you leave the tape on the joists overnight.

You can remove the tape by warming up the tape in the oven. Doing this in the morning allows the tape to dry fully. Once the tape is dry, you can take the tape off, and it should be safe to use it again.

You can use the same tape for your joists for a couple of years, but if you notice any deterioration of the boards, it’s time to replace them. One of the first things you should do is cut the joists open. If you have tape around the boards, it is easy to undo them.


Deck joist tape is available in different strengths, depending on how much sealing you want. It can also help to stop stains and odors in your deck. You can choose between the normal tape strength and a thinner version that will only provide a seal for a small amount of time. The thickness is less important than how strong the seal is. A strong seal is always best, but you can find different versions if you only want a temporary seal. Some decks will not need any work done to them, but this tape could be perfect if you need to extend their lifespan.

Deck joist tape can be used over and over again. It will not discolor, which is great for decks. It also will not fade. This means that you will never have to repaint your deck.
