The Best Waterproof Tape for Deck Joists

We all love a good and sturdy deck, most especially during the summertime. On days when the sun seems to be shining brighter, we would all just love to lounge around and get some well-needed vitamin D on our decks. And if we are feeling festive, the whole gang would probably be there with us as we grill up some barbecues and enjoy a good laugh.

On the other hand, we need to make sure that our decks are in their best shape to keep enjoying the party with no worries. As fun as having a deck sounds, it does come with a number of common problems. Among those are:

* Loose ledger
* Weak posts
* Cracked concrete piers
* Bad beams
* Defective decking
* Faulty floor deck joists
* Water molds
* Unsafe stairs

The problems mentioned, if left untreated, pose a significant threat to the safety of whoever steps on the deck because the possibility of it collapsing is considered high. In fact, even just a tiny defect on the deck can already ruin the entirety of it. Luckily for us, there is a product that can solve most of those listed problems, and that product is a waterproof tape for deck joists made by Walther Strong.


A deck tape is built to be resistant to water so that it keeps moisture from infiltrating the frame of a deck. It is used as a protective seal on new or existing frames of the deck from water damage such as moisture rot, weakened frame, water molds, and more. This is an essential product since the traditional lumber used in most decks are prone to water damages.


Waterproof tape for deck joists made by Walther Strong greatly differs from others in the market because it is non-butyl. This means that deck tapes by Walther Strong are the most suitable for deck protection because they are not susceptible to ultraviolet radiation from the sun and, as a result, last longer than their competing products. They have an approximate life span of 50 years, and Walther Strong gives a guarantee of 25 years.

Moreover, waterproof tape for deck joists made by Walther Strong is self-sealing and manufactured from an extremely tough polymer acrylic adhesive which makes it not only waterproof but also weatherproof. In addition to that, this deck tape can withstand temperatures from as low as -40C to as high as +93C without cracking, weakening, or peeling.

Another thing that is great about this deck tape is that it is smooth to use. You will still be able to smooth slide your boards even after applying this tape. Furthermore, this deck tape is thin and does not add extra height to your deck, even if the tape is overlapped. This is an essential factor because it does not compromise the structure of your deck. Lastly, this tape does not stick to its own adhesive and therefore reduces waste. It also does not leave any residue.

Waterproof tape for deck joists made by Walther Strong has been tested and proven to work with all traditional timber decking and also modern composite decking. Here is a quick summary of its benefits:

* Waterproof
* Weatherproof
* Airtight and smoke tight
* Ultraviolet radiation (UV) stable
* Strong adhesive
* Non-butyl
* Self-sealing
* Wide range of available sizes
* Ease of usage
* No added height


A deck tape mainly solves your deck problems by protecting it from water penetration. Since your deck is out in the open, it is exposed to several outdoor elements that could result in damaging the deck frame and thus its destruction. The damage commonly occurs at the deck joist sealing tape or the spot wherein the deck boards connect with the deck substructure. When these parts are damaged, the most likely problems above will occur.

For example, a composite deck will absorb more moisture from its deck boards and into the deck substructure and thus will weaken the deck. This is because greater amounts of moisture will lead the frame to rot faster. With that said, you will need a protective seal to prevent the water from penetrating the material.


We know what you are thinking. You are probably asking why you cannot just buy a new deck or replace the damaged parts. Although this is a solution, deck tape offers you prevention. As the saying goes, prevention is better than a cure.

Waterproof tape for deck joists made by Walther Strong is your safety measure. It is surely worth investing in because it gives your deck a healthy substructure which is a vital component for the overall stability and condition of your deck.

The waterproof tape for deck joists made by Walther Strong benefits you by:

* Prolonging the life span and usability of your deck
* Saving you from larger fees such as replacement costs and maintenance expenses
* Improving the structure of your deck for a worry-free experience
* Keeping you, your family, and your guests safe from unexpected accidents


You may apply the deck tape along the top part of the joists. Use firm pressure to make sure it sticks and to remove the air bubbles. You do not need to wrap it around the entirety of the deck tape for joists. Covering the top part is already enough to protect the timber from any moisture. You can also use the deck tape to protect the posts of your deck to strengthen its structure. You may also apply some deck tape on the galvanized fixings to prevent them from rusting.


Deck tapes are designed to be water-resistant in order to protect your decks from water damage and thus, strengthen the structural integrity of your deck. The best waterproof tape for deck joists is the one made by Walther Strong because it is non-butyl which means it is UV stable and lasts longer compared to others. Investing in deck tape benefits you by prolonging the life of your deck, saving you from extra costs, improving deck structure, and minimizing your risk for safety.
