ABOUT 90% OF THE PATCHES WE SEE HAVE 900% TO MUCH GLUE.----- Think Thin.
TOOLS:
Soapy
water to locate leaks after boat is pumped up tight Stiff Brush (cut bristles of a cheap brush to about 1/2 inch)
60 grit sandpaper
Fabric
Pen or China Marker
Paper cup or small glass jar
Stiff putty knife (dull) or similar tool for
working in patch
Acetone or Toluene for Hypalon (rubber boats)
Paper towels
Methyl Ethyl Ketone MEK for PVC (plastic boats)
Confident attitude
WORK
AREA: Shaded and free from dust. Good ventilation
will reduce inhalation of the toxic vapors.Avoid high humidity if possible.Make
PVC repairs in the early morning before the temperature gets too high.If you must work in the sun, cover your work with a towel between coats.
PREPARE
THE PATCH: Your patch should cover the damaged area
plus 1-1/2 inches.For example a pin
hole leak will take a 3” X 3” patch.Round
all corners of your patch.
MARKING
THE BOAT: Trace the patch onto your boat using a pen
or china marker. If possible patches should be done on an inflated boat.If the hole is too large this will be impossible.
PREPARE
THE SURFACE: For Hypalon boats--You should rough both the
boat and the patch with 60 - 80 grit sandpaper.When properly sanded the material will be completely de-glossed.It is best to sand a bit past your outline, a little excess glued area is
better that not having enough glued surface.You can clean the excess glue off later.Once sanded, clean both surfaces with solvent. Acetone or Toluene.
For PVC
boats--Wipe the boat and the patch very, very, very well using Methyl Ethyl
Ketone (MEK).If there is an
excessive amount of glue on the boat, attempt to remove it.
ADHESIVE: Pour or mix the amount of glue you feel you
will need for the task in a paper cup or small jar. Be sure to keep your working
glue covered when not using.The pot
life should be one to two hours if you keep it covered.
APPLICATION: Glue should be applied aggressively.Coats must be as thin and even as possible.Apply to both patch and boat.Apply
the first coat and wait about 10 minutes. (Longer if it is below 75 degrees).Apply a second coat to the boat and the patch and allow 5 minutes to dry.NOTE:THE FIRST COAT CAN GO
15 OR EVEN 20 MINUTES BUT IT IS VERY IMPORTANT THAT THE SECOND COAT GO NO LONGER
THAN 5 MINUTES.
JOINING:
Immediately
at the 5 minute mark lay the patch starting at one side and rolling through to
the end of the patch.Using a wooden
spoon or something flat and stiff rub out the patch.You are simply trying to press down on the patch.If there is any air under the patch it is to late.With PVC glue you should let set overnight. With Hypalon glue you can use
the boat the same day but be gentle with it.
