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.

Attractive, easy to install, nicely equipped hardware package.
Color: B. Rustic Brown - Americana Farmhouse Style, Number Of Shelves: 2, Size: 22.5inches
These are pretty doggone nice shelves and I appreciate the fact that they are not made of solid particle board. Yes they are made of an engineered product, but they are lightweight and strong…and look better than particle board products and more costly than their actual price. Easy installation system with the bracket…not fussy like some are. An especially thoughtful touch is the variety of hardware that is included. Also a tiny level for use when installing them. What? …So they can be installed correctly? I was pleasantly surprised by this inclusion.

If the set screws were white the shelves would be perfect.
Color: C. White - Modern Minimalist Style, Number Of Shelves: 3, Size: 15.7inches
I'd give 4 1/2 if there was one. The shelves thwmself are nice I just don't like the visible little black set screws. The shelves themself look great and are not wobbly at all if you install correctly. I purposely installed the bracket upside down because of the little black setting screws; I didnt want them showing because the shelves are above eye level and the screws are black and I didn't want them showing. But that made the shelf lean amd wobbly so I turned them back over the way they are supposed to be and that made them level and sturdy. I guess I'll paint the little screws.

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️
