If the hole is only small, cut out a round patch of no less than 60 mm diameter. Larger holes or
cuts will require proportionately larger patches but always ensure you have at least 30 mm of
patch around the perimeter of the cut or hole and the corner are well radiused.
Next hold the patch on the tube and mark out around it with a pencil.
Clean both surfaces with solvent and spread a thin layer of adhesive over them ensuring there
are no lumps.
When first coat is dry to the touch (about 10 to 15 minutes) apply a second thin coat. After
waiting 5 or 6 minutes, touch the adhesive with the back of your hand. If it no longer appears
wet, heat both areas with a hot air gun to re-activate the glue and join the patch to the tube and
then clamp or roll the surfaces together. For the best adhesion, roll over the patch with a roller
or over the bottom edge of a bottle.
Do not inflate the boat fully for 24 hours.
Repair Hypalon boats
3D Tender boats that have tubes constructed dwith Orca Hypalon coated fabrics cannot be
bonded with plastic adhesive or by welding. They require neoprene based glue and RFE harden-
er. MEK solvent is recommended to prepare the surface before gluing. Use only recommended
solvent and adhesice.
Identify the area to be patched. This can be done by running water over the suspect area or
spraying or brushing with soapy water..
If the hole is only small, cut out a round patch of no less than 60 mm diameter. Larger holes or
cuts will require proportionately larger patches but always ensure you have at least 30 mm of
patch around the perimeter of the cut or hole and the corner are well radiused.
Next hold the patch on the tube and mark out around it with a pencil.
Use a grinder, course sand paperor scratch stone, rough up both the back of the patch and the
area marked on the tube.
Clean both surfaces with solvent and spread a thin layer of adhesive over them ensuring there
are no lumps.

Danger
Glue and solvents used for repair are highly flammable. Perform repairs in a well ventilated
area. Avoid breathing the vapors, wear protective gears (goggles, filter respirators, latex
gloves.
