    Hi All & wishing a very Happy New Year to everyone, hope you all had a good break for Xmas.

    I’m just wondering if anyone has any experience on the difference between these two products?

    They basically appear to be VHB tape adhesive improvers.

    I have used 94 a good bit with great results but I’ve also seen the 83 appear with some suppliers & wondered if it would work as well as an alternative? It’s cheaper for a larger quantity too.

    Hi Myles

    All the best for 2021 for you to mate!

    which VHB tape are you using and for what surfaces?
    also, what sort of size panels is it holding etc?

      Thanks Rob.

      Usually 3M RP45 or a similar non 3M brand. This is 90% for attaching channel to the rear of ACM panels of varying sizes. I always add rivets too for peace of mind unless they are very small signs in low level locations.

      It’s probably OTT with the addition of rivets but I like my sleepšŸ¤£

      I have seen it said that it will only work on 3M tapes or vinyl, but it definitely does work on other brands. (well at least the 94 does from my experience)

          Hi Hugh, Happy New Year to you. I actually ended up getting a different brand supplied now by Sign & Digital (I think to complement their VST tapes) as a replacement for the 3M product.

          I haven’t yet tried it but presume it will do the exact same job.

            Happy New Year Myles,

            Thanks for the reply, I’ll take a quick look into it!

            Best

            Hugh
