HD Protect, Joist Tape, Premium Joist and Flashing Tape Perfect for Decking, Superior Self Sealing, Extends The Life of Timber Joists by Preventing Rot, (118 Millimetres x 20 Metres, 1, Count)

The media could not be loaded. Used this tape last week on a large 3 by 8 metre raised deck. Tape is heavy and feels quality. Is like a latex rubbery coating on the tape and gives a resolute looking finish. Initially tricky to apply on the deck frame, but sped up as I got more systematic, did all the main deck in under 3 hours. Sticks really well to the wood, a bit like chewing gum. It was really hot, 20 degrees, and some of the tape did bubble in places, but these went down as the evening cooled. Tape was wide enough to fold over either edge of joists which was what I wanted. Very pleased with result and hope this may get me a few more years out of the frame under my composite boards.

Super speedy delivery! Highly recommend the company and the product to help protect decking wood.

Bought for decking joists, easy to apply, I unrolled the tape for the entire joist length, removed a small section of the white backing to applied the tape to the end of the joist, then moved along the joist removing about a metre of backing and applying the tape to the joist, applying a little pressure to ensure adhesion. It’s an easy process and went on without any problems. I used a Stanley knife to cut, which was no problem.Nice wide tape to cover the joist upper surface and over the edge. They are expensive but if it increases the life of decking then saves time and money in the long term!

Really easy to apply, just wide enough for 45mm joists with a bit of excess to fold over the edges, and stays put once it's on.The adhesive is annoying to remove if it gets onto anything, but this is only really an issue where boards are fixed down then removed (e.g. for final adjustments) which squeezes out the adhesive.

Protects the timber joists and posts beneath the decking and should last for decades!

The tape itself seems to go down well. However, I had specifically chosen this tape because it claimed to be 63mm wide which would have given plenty of overhang either side of the joists. Given it is more expensive than many of the other tapes which do the same I was extremely dissapointed to find it is only 55mm wide (see photo), barely wrapping around the edges of the deck joists. Not sure it is worth the extra given its actual width is comparable to other brands.

Fantastic quality tape. well worth it

I don’t like leaving 1 star reviews, but in this case I have to. I’m a professional tradesmen. I need products that i can rely on. This sadly was unreliable. I bought this for final parts of a decking subframe that needed protecting. I had ran out of my main deck tape product (Walther Strong Deck tape) and thought I’d give this a go as there was a discount and it was better value for money for a last minute purchase than my main product. I’ve never used this product before but I like to give different products a try. The project got delayed and I was unable to use it straight away. I had stored it away correctly in the meantime. When I came to use it I had nothing else at hand. I was completely unable to remove the tape from the white backing paper. It was a mess. I felt like a character in a venom movie. It would not separate, therefore it was useless. This unfortunately cost me time and money. You cannot sell a product that is as unreliable as this. I immediately tried to return it but I was 2 days over the return cut off point, and had no way of contacting the seller either. Hence why I have left a negative review. I always try and get in touch with the seller first and settle things with them, rather than leave a negative review. I’ve read some reviews saying that some rolls have been faulty and have had the same problem. Even if the tape itself is good, it can’t be a hit miss thing as to whether you can actually take it off the roll or not. If you want to keeps things simple and easy and want a product that is forgiving, then use the Walther Strong Deck Tape Instead.[Edit on 13/09/21]changed from 1 star to 3 stars. I was contacted by the seller with a refund confirmation and a free roll from a different batch. They apologised for there being a bad batch and are resolved to get to bottom of the problem. I will try the new roll and leave another review.[Edit on 29/09/21] I will increase the rating to 4 stars due to very good customer service. I was sent out a new roll. The new roll seemed like an upgrade, with a new type of backing paper. Tried it on exterior timber frames that were to be covered up. I would say its best to work in lengths of about 1 metre at a time as it’s hard to control longer lengths due to its stickiness and flexibility. As it’s bitumen based it will adhere very well and be very difficult to remove. One thing I’ve realised is; keep the roll cool or in the shade. It becomes very hard to use if it’s hot. It’s much easier to handle cold. Ease of use is still the big downside of this product, but no doubt it will waterproof timber for a very long time.
