Our Bestsellers

Pioneers of Deck Tape since 2012

At Walther Strong, we saw what the industry was missing: a purpose-built solution to prevent rot and prolong the life of decking structures from the ground up. So, we developed Deck Tape — the first tape engineered specifically to protect decking subframes from moisture ingress, UV exposure, and weathering.

With Bear Hands UK
The Walter strong deck tape is an absolute game changer when working with decking. Taking time to build a lovely decked area deserves going the extra mile to make the structure last as long as possible in all the elements. I’ve used this tape along all the top of the frame work to this massive deck I built last year. Paired with a decent air flow gap underneath I know that this deck is going to stand the test of time and all the weather the UK can throw at it. So simple to install Can’t recommend it enough as a vital part of any deck building project
JJS Decorating
This stuff is a game changer. With 17 windows to paint, inside and out, each with 4 panes of glass, I was starting to lose the will to live! Then I found Walther Strong H20 Primer and Liquid Mask. Saw similar first on Instagram in USA so searched for a UK alternative. This should be in every DIY store and paint suppliers in the country. Does exactly what it says on the tin. Save product by just painting around the frame of each Georgian bar, not the whole window pane. It peels off like plastic tape.
Golden Valley Landscapes
As a professional Landscaper, we always encourage our customers to use Walter Strong tape on all of our timber installations. In addition to using a pressure treated timbers, we will always opt for using an extra layer of protection by using these tapes. As an installer, it gives us confidence in our installations, knowing our customers will have decades of use from whatever timber products we install. We're so confident in the product, we've even made a video on the Golden Valley Landscape Gardening Facebook page, which shows how we use the Deck Tape.
Painter and Decorator
I've been a painter and decorator for nearly 30 years now and until recently always ether cut my windows in by hand or used precision masking tape when needed. I have recently finished a job with 22 external Sash windows and used H20 liquid mask on all the windows the end result was fantastic and very tight cut in lines achieved...

Have been purchasing Walther Strong products for over a year now and had next to no problems what so ever. They are affordable, reliable and slowly becoming accessible everywhere! Would highly recommend.

If you're looking for a product that saves you masking up then this H20 is the one! Absolute game changer, saves me so much time and is so satisfying to peel off.
