DeckTape Pro ® completely protects and seals your new or existing deck frame, protecting from water rot, moisture rot and frame weathering. 


Deck Tape Pro® is a non-butyl self-sealing tape manufactured from a massively strong polymer acrylic adhesive, which gives a completely waterproof and weatherproof seal.

With a permanent adhesive bond for 50 years and a 25-year guarantee, this greatly adds to the life of your deck frame. Tested with all timber treatments.

Suitable to be used with both traditional timber decking and also the more advanced composite decking, Deck Tape® will protect any timber decking substructure.  When using a composite deck board, more of the moisture will be absorbed into the substructure as it will drain off the deck boards.  Higher amounts of moisture will mean that the frame will rot faster if not sealed properly.



Exposure to the elements outdoors can result in significant deck frame weathering.  The most common area for this damage to occur is where the deck boards come in contact with the deck substructure. Deck Tape ® and Deck Tape Pro® are unique due to its adhesive properties. The adhesive in the tape cures into the timber subframe and BREATHES with the wood when absorbing moisture which prevents the tape from cracking. In addition to this the adhesive will self seal around the fixings meaning that the penetration points of the deck get sealed too. This is something that a majority of decking products cannot do.



Deck Tape Pro® is a non-butyl tape – thinner and more durable meaning no uneven layers to install over.

Non-Butyl tapes are particularly suitable for this application as they are completely UV stable and keep their integrity for longer.  This means that they have many advantages over both butyl and asphalt tapes.

In addition to this, it is stable from -40C to +93C with no cracking, peeling or strength loss.

It’s 2.5X bigger and 2.5X faster than Deck Tape, and is LINERLESS! , so it saves a lot of time when you are decking installer doing large projects on a regular basis! A must try if you are a pro decking installer looking to improve your subframe protection times and speed.

Product Instructions


Joist Protection

Simply applying a strip of Deck Tape Pro® along the top of the joists as a ‘cap’ (rather than a wrap) protects the timber as it creates a strong seal from any moisture. This prevents any moisture sitting on these flat surfaces and slowly rotting away the timber.

Deck Tape Pro® can be applied to joists in advance to the deck boards being fitted – It doesn’t deteriorate or affect the benefits and qualities that the tape brings to the deck.

Joist Hanger Protection

Traditionally the coating on the metal would have slowly corroded away the metal and brought weakness in.  However, by simply applying a layer of Deck Tape Pro® this prevents the breaking down of the treatments so the subframe of your deck maintains its integrity.

Cut Ends

Generally this is a particularly weak spot for the moisture to start rotting the timber since there will not be any treatment on this part as it has been cut to size.  Using one layer of Deck Tape Pro® will completely seal it off from all moisture and water-rotting or weathering.

Around fasteners

Apply a layer of Deck Tape Pro® between the galvanised fixings and treated timber to prevent the fixing from corroding.


Essentially if you are a long time decking installer or someone who needs fast and quick installation times you cannot afford to discard this product. Its the best subframe moisture protection in the market, its quick to apply and is the only tape that has an adhesive that can self seal around fasteners. If you haven’t tried us before you really should – this product will increase your builds longevity and durability for years to come.
