How to Repair Inflatables
with HH-66

HH-66 is safe and simple to apply on PVC inflatables.  Follow these three steps for a seal that won’t fail:

Prepare

Cut a vinyl patch with at least a 2-inch overlap on all sides.  Round the corners to prevent peeling.  Clean the area with alcohol wipes or our HH-66 Thinner.

Apply

Spread an even layer of HH-66 Vinyl Cement on both surfaces.  Let it sit until tacky (about 2 minutes).

Attach

Press the patch firmly onto the damaged area.  Apply even pressure to smooth out air bubbles.  Remove excess adhesive.  Let it bond for at least an hour before use.  Full strength achieved in about 24 hours.

FAQs About PVC Inflatable Repairs

To patch a vinyl inflatable with HH-66, follow these steps:

  1. Cut the patch 2 inches larger than the tear on all sides.  Round the corners to avoid peeling.  Clean both surfaces with HH-66 Thinner.
  2. Brush HH-66 Vinyl Cement onto both surfaces.  Wait until tacky (about two minutes).
  3. Press patch on firmly.  Apply even pressure to remove air bubbles.  Remove excess adhesive.  Let it bond for one hour.

See the full vinyl patch guide

Use 1 ounce for every square foot of vinyl you’re bonding.  That covers both the patch and the vinyl surface.  Small repairs take 1–2 ounces.  Bigger jobs may need 4 ounces or more.

HH-66 bonds in about an hour, but it reaches full strength about 24 hours after application.

HH-66 creates a bond that’s stronger than the vinyl itself.  Depending on frequency of use, the bonds created by HH-66 can last the lifetime of your inflatable boat.

HH-66 is best for repairing rips, tears, and punctures.  If the seam provides a 2-inch overlap or more, HH-66 can be a good option for this type of repair.

HH-66 is ideal for PVC vinyl-coated materials, such as inflatable boats, mats, sports covers, etc.  HH-66 is not appropriate for Hypalon materials, and it also is not recommended for use on EVA traction pads.  For non-vinyl material repairs, check out our other available products.

HH-66 can work on wet vinyl.  For an optimal repair, wipe the vinyl dry and clear off dirt & debris using HH-66 Thinner or a compatible solvent when possible.

The standard kit (which includes a 10″ x 10″ vinyl patch) repairs a tear around six to eight inches in length, as we generally recommend about a two-inch overlap on all sides of the damaged area.  The industrial-sized XL kit includes a 30″ x 36″ piece of heavyweight (22 oz.) vinyl.  Choose the patch kit size based on the size of your tear.
