Spod’s guide to repairing
Neoprene and Hypalon
For the purposes of the guide 'Neoprene' includes the material
Hypalon and includes X-Tuck. Contrary to popular belief neoprene
is a very fragile material. The reason that is it used in high wear
products such as spraydecks is simply because there is no other
material offering similar performance. Neoprene is constructed from
one or two stretchy layers of thin nylon laminated to a squashy
layer of foam. Imagine your spraydeck is an over-ripe peach wrapped
in cling film and your paddle shaft is a meat tenderising hammer.
Now imagine that you are in a very bad mood… Needless to say,
at some stage you are going to have to repair it!
If you do a lot of whitewater kayaking you will soon become a master
neoprene craftsman; the tools of your trade will be:
GULSEAL or EVOSTIK* - Yes, common
or garden Evostik from your local hardware store is the business.
This is a contact adhesive and should be used to butt-join tears
in the neoprene. For extra strength apply two layers fifteen minutes
apart and then join the surfaces after a further ten minutes. Bonds
will be much stronger if the frayed nylon edges at the sides of
the tear have been fully impregnated with adhesive. After bonding,
a fin line of Gulsure should be applied along the top of the tear
on the nylon side only.
GULSURE or AQUASURE* - This is
a urethane based adhesive. It has inherent strength and body and
is ideal for replacing areas of lost neoprene (back the hole with
a piece of parcel tape first) and for beading along the top of repairs
in the place of blind stitching where nylon joins nylon (Gulsure
is stronger than blind stitching). Unfortunately repairs take up
to 24 hours to dry (accelerator is available) and although it looks
pretty thick this stuff will run, so everything needs to be held
flat until it is dry. Once opened, tubes last for about one month
before going off – this happens even faster if you leave air
in the tube. Gulsure is a nightmare to work with – looks like
snot and sticks like Sticky the Stick Insect after a particularly
large jam sandwich. You have been warned!
MATCHSTICK* - Yes, believe it or not the common
household match will be your light sabre as YOU, Luke Skywalker…
Matches are great for spreading small amounts of glue around, and
what’s more they only cost 0.000000001p so you can chuck them
away before the glue spreads up to your elbows!
So to summarise, use Evostik to bond neoprene to neoprene and wherever
possible join nylon to nylon with Gulsure. Don’t be a Spod
and stitch your deck – the water will go straight through!
Using the above tools you can fix almost any damage to neoprene.
You bought it to destroy it, so get on with it!
