What it is used for

  • Protecting timber joists and bearers on outdoor decking subframes from water ingress and moisture rot
  • Creating a watertight seal under composite decking boards where the fixing screws pass directly through the tape
  • Sealing the top face of treated timber deck substructures to extend service life in exposed UK climates
  • Providing a low-friction surface that allows composite or timber boards to slide easily into position during installation

Fitting and handling

Deck tape can be applied to damp timber and in sub-zero temperatures, making it practical on British building sites year-round. Simply peel and press the tape along the full length of each joist before laying boards - the tape self-seals around screw fixings as you drive them through, so no additional sealing is required at fixing points. Rolls can be overlapped without adding significant height to the subframe, and the tape is repositionable before final pressing so you can correct alignment without waste.

FAQ

Does deck tape work on treated timber joists?

Yes. Walther Strong Deck Tape adheres to treated and untreated timber, including damp timber, so it is compatible with pressure-treated C16 and C24 joists commonly used in UK decking subframes.

Which width should I choose - 50mm or 100mm?

The 50mm roll suits standard 47mm joists where you want edge-to-edge coverage with minimal overhang. The 100mm roll is better suited to wider bearers, doubled-up joists or situations where you want the tape to wrap slightly down the joist sides for added protection.

How long does deck tape last once applied?

Walther Strong Deck Tape is rated for up to 50 years of service life. It is fully UV stable, so exposure through gaps in the decking boards will not degrade the adhesive bond over time.

Nice shoes for about a year and a half
Size: 13 Wide, Color: Brown, Size: 13 Wide, Color: Brown
I bought these shoes about a year and a half ago and they are comfortable and look much more expensive than they actually are. Today, I noticed them starting to tear a little bit, but if I can replace them every 18 months for this price, it is probably still a better value than high end shoes. The grip is good for dress shoes and has held up well, and they are a good fit that does not cause blisters from excessive rubbing. I might not choose these if I need to wear them every day because of their lifespan, but for a once or twice a week pair of dress shoes, they are a good value.

Fantastic Shoe for the Price
Size: 9.5 Wide, Color: Wingtip Black
Okay, I’m used to spending big bucks on men’s dress shoes. I’m talking $300 plus for American made shoes. They are recraftable (resole-able) for another $100 each time. But since Covid, I don’t go to the office as often. One of my black dress shoes needs to be re-soled, and it will be. Just not now. So I ran into these shoes on Amazon. It’s hard to argue with the price. Literally 10% of what I have been paying. So, are these shoes 90% lower in quality? The short, simple answer is, surprisingly, no. Just the opposite. Upon receipt, I inspected them carefully and they looked pretty darned decent. I was looking for any excuse to plop them back in the box and return them. I couldn’t find anything. I appreciate that the leather upper is smooth and mildly shiny. This is a wing tip style shoe, so I’m impressed that the extensive stitching was evenly spaced. The leather detailing that I expect on a wing tip is also all there. Inside the shoe, it is lined from the toes all the way to the heel box… nice! And that leather feels surprisingly supple. That is something I would expect on a much more expensive shoe. But definitely not at this price point. Hmm. I even liked the wax laces they chose. They are a little thicker and have more than adequate length. The shoe’s eyelets have interior facing metal grommets to protect against stretching and tear out of the leather and helps protect the laces against friction wear, as they are tightened and loosened over time. Now having that detail, at this price point, has raised both of my eyebrows. Double hmm. Now I am really impressed. The only thing that I didn’t like was that the stitching—that joins the uppers to the sole—is white. I needed to polish these shoes anyway, so I figured I’d see what would happen if I put black polish on the stitching. I’m happy to say that the uppers shine up very nicely, to a high gloss. This was done with just a little bit of buffing, using a traditional horse hair bristled brush. And followed by a buffing cloth. Although I didn’t do it, the leather is smooth enough that I probably could have spit shined them. And those pesky white stitches on the top side of the soles? Well I’m happy to report that they are now definitely black. Turning the shoe over, I can visually see a lump where the shank is supposed to be. That’s a good thing. Not all shoes have a shank. It helps to support the arch. That’s another nice detail. I am expecting the shank to be plastic at this price point. So I am utterly shocked to report to you that a magnet sticks to the bottom of the shoe. That shank is steel! Now I am amazed! We’re talking mind blown, Purple smoke everywhere. Speaking of details, I was very surprised to see the nicely done wing tip detailing, from on top of the shoe, carried over to the bottom of the sole. Wow. I have never seen that before. That’s surprising. Now it is important to point out that the sole is some man made material. Definitely not leather. But that’s okay. Especially in the wet, leather wears out quickly, if you don’t wear rubber over shoes. One less thing to fuss about. The heel itself has a band/layer of rust brown material sandwiched between black layers. I wonder if that is a cork or bamboo material? Having walked in these shoes, on concrete and tile floors, last week, there is a noticeable level of cush, or give. They will definitely not to be confused with sneakers. But for dress shoes, this is a pleasant and surprising experience. The first day, I wore them at home, over the weekend and I’m glad I did that. They needed time to adjust to my feet. Any dress shoe that I have ever worn needs that. But after that, these shoes have been pleasant enough to walk around in at work. I’d have to say that these shoes give me at least 90% of what I would expect from my $300+ shoes for around 10% of the cost. In my estimation, at their current price point, they constitute an excellent deal. And especially if you are just breaking into the business world and need a good pair of interview shoes, these are definitely respectable… just be sure to put black polish on the white stitches. Oh, BTW, I have wider feet and I ordered the shoe wide. After the initial stretching, they fit nicely. So, in the final analysis, what do I think? I have to say, yes, these shoes definitely get my recommendation. Especially if price is a huge factor, then these shoes constitute an excellent deal.
