    Patching a membrane suit

    Having scraped my arm against a sharp rock in a swimthrough, I'm having to endure my last few dives in Bermuda with a wet arm.

    What's the best thing to patch it with when I get home? Anyone tried those Stormsure TUFF patches?

    I'd use a two part glue like Alpha 2000.

    First use a bit of masking tape on the outside to temporarily close the scrape then work on the inside.
    Depends how large the cut/scrape, but better to use a wide 40mm tape then thinner stuff and if
    near the elbow etc, maybe even put a couple of transverse strips to reinforce. Roll it hard with a wallpaper
    roller and put a weight on it for 2 days.

    Once this lot is done then put a strip on the outside, Can use masking tape to make the area neat
    and cut tape to suit slightly smaller than the slot. Again once done use a weight for two days.

    Depending on the material you may need to rough up a bit with some grit, clean with MEK and
    use two coats before contact, Some suits usually those that use heat tapes don't take glue well
    unless it's got a primer coat first then the final contact coat, so doing the inside allows to have a
    play. Even if the membrane takes glue ok, two coats won't hurt. Dust the lot with talc after and pump
    up to check for leaks.

    I see I can get that glue on eBay. Where do you get your tape from?

    I’ve used the tuff tape, or the other brand I can’t remember the name of that even sticks under water, on a slice in my knee crawling out of a quarry. Been on over 2 years now, still dry, still passes pressure test when sent suit in for other leaks. If it’s a linear tear or slice you can match the edges of, I’d try the tape initially, cheaper and quicker. (I fixed my suit between dives before a week on a live aboard!)
