Poly/Plastic Repair Kit Instructions

GET STUCK POLY/PLASTIC KAYAK REPAIR KIT for Cracks, Holes and Fitting Leaks

Repair Poly/Plastic Kayaks including Leaks, Cracks, Hatch and Bulkhead Sealing. Bond Wood and Metal to the Poly/Plastic



1. Clean bond area with Denatured Alcohol Swipe, roughen with 60 grit sandpaper, clean again with Swipe.

2.Cut the glue syringe at the groove 7/16” from the tip. Remove cap located in the blue plunger to allow plunger to push into syringe.

3. Depress blue plunger causing desired amount of glue to dispense, mix resin & hardener equally to a consistent color for at least 2 minutes.

4. Apply glue to both parts to be bonded, press joint together leaving some glue in the joint.

5. At 70˙F the working time=30 Min, Handling strength=4 Hrs, Full Cure=24 Hrs.

6. To remove uncured glue let it cure until just after it is no longer liquid, then cut and strip off. Once glue is fully cured it is very difficult to remove.  Warmer temperatures shorten cure time, lower temps lengthen cure time.

Prepare to Bond Polyethylene(Plastic),
(don't flame treat PVC!) by Flame Treating :

Flame Treat:

1. Fit a propane torch with a flame spreader.

2. Following the operating cautions of the propane torch, ignite the flame.

3. Observe the flame in a darkened room, noting the primary (bright blue) and secondary (faint yellow) portions of the flame.

4. Adjust the flame so that the primary flame is contained within the spreader, and the secondary flame is 1-1/2" beyond the spreader.

5. Treat the polyethylene to be bonded with the tip of the secondary flame by passing it over the polyethylene in 5 gentle strokes. Total exposure to the flame should be 2-3 seconds (.5 seconds per stroke). This light exposure should not deform or melt the polyethylene in any way.

6. Test the polyethylene for bond readiness by wetting it with water. If the water beads or runs off immediately, the treatment was not effective. If the water sheets-up on the surface, the surface is ready for bonding. If unsure, compare the water's action on the treated area with an untreated area.

7. Bond joints within 1 hour after treating. Always prepare test bonds to be certain that flame treating is effective with your material. DO NOT FLAME-TREAT FUEL TANKS even vapors in tank are unsafe.

Poly/Plastic Kayak Crack and Hole Repair:

Prior to bonding Flame treat any Poly (don't flame treat PVC!) to be bonded per instructions above. CAUTION:DO NOT FLAME TREAT THE SUPPLIED PATCHES! Cut patch material 2“ larger in all directions than the hole or crack to be repaired. Turn off any water pressure. Apply glue liberally to both the patch and the tank. Do not apply to one surface and expect the glue to transfer to the other when pushed together. The glue is resistant to dripping even on vertical surfaces so use enough to fill any uneven areas between the patch and tank. It is OK for the glue to be very thick, it will cure to become a strong, flexible plastic. If needed, hold the patch in place with duct tape while curing. Use an UltraWax Sheet over the patch to push it into place and to feather the glue on the edges. UltraWax Sheets may also be used to force glue into a crack without the use of a patch. Remove UltraWax Sheet after glue is cured. Note: Poly or UHMW may be bonded without flame treating but the bond is approximately 1/20th of the flame treated strength. Note: When bonding non porous surfaces such a Poly/Plastic, Metal or Glass insert spacers into the glue after applying to the surfaces to be bonded. These spacers can be made from short pieces of fishing line and will act to keep all of the glue from being squeezed out during clamping.

Poly/Plastic Hatch/Bulkhead Sealing:

Prior to bonding Flame Treat Poly/Plastic (not PVC!). Dispense glue into a strong plastic bag. Cut the corner of the bag to a desired bead size. Squeeze the glue through the cut corner's hole onto the area of the hatch that you wish to seal. Use an UltraWax Sheet (cut a strip to fit) over the glue to push it into place and to feather the glue on the edges. Remove UltraWax Sheet after glue is cured.

Bond Poly/Plastic to Wood, Metal:

Prepare the Poly/Plastic per flame treating instructions above. Clean metal with Acetone, Denatured Alcohol or MEK to remove an oil or other contaminants. Porous wood may be coated with glue and clamped without spacers.
