Step 3: Repair methods for 4 types of damaged inflatable

Damage 1: Pinhole, small hole, or tear

Small hole

Point 1: Clean the damaged area

Clean the torn area, wipe away the dirt, grease, mud, water, and debris from the surface. I did this to make sure the patch can be better sticking.

Point 2: Cut the edge of patch round shape

For stronger adhesion, I prefer to cut the patch into a round edge. Rounded corner patches stick more firmly and do not fall off easily. I will measure the size of the tear, and cut a patch in 4 sides 2 inches larger than the tear. This makes the seal more tightly, durable, and sturdy.

Point 3: Mark the torn area

Put the patch on the torn area, mark it around it with a pencil. At the same time make a special mark on both patches and torn apart. So that you will know where to glue later.

Point 4: Apply the glue

Check the torn area and waiting for it dry. Apply glue on the torn area we drew just now. Do the same thing for the patch too. I have two little tips here. First, the glue will be an even and thin coating, not too thick. Second, Make sure to glue on the rough side of the patch. This is the secret to better stick.

Point 5: Flatten the patch

Waiting for 2 to 5 minutes and allow the vinyl cement to dry. Or you can touch your patch, feel dry but not dry too much. That is a feeling your finger is not stick on it. Now you can flatten the patch on the torn area. Here you need a blower or a roller. Tools help faster dry and press stronger. Make you more effective. Forget about these tools if you don’t have anything on hand. Just use your hands. Heavily press them again and again until they patch together tightly.

Point 6: Final check and make sure it is firmly sealed.

Now you get a nice and sturdy patch. Let’s final check the patch to see if it adheres to the inflatable. Wipe off the excess glue with a rag. Wait for 2 hours and make sure it is totally dry. Jump hard on it yourself. Congratulations you did a good job if everything is ok.

Damage 2: Small rip

Indeed it is not complicated to fix a small rip. Just a little difference from patch a hole. Need do one more step. We repair from inside before we do outside.

In order not to repeat me I will only explain this new step. All the other steps you can follow in repair a hole.

Key 1: Patch from inside after we drew around with a pencil.

Key 2: Clean the inside surface of the inflatable before applying glue.

Key 3: Coating thin glue both on a patch and inside surface. It is better to find a helper if it is hard to applying glue on the surface.

Key 4: Let the patch go under the rip after dry.

Key 5: Flatten it.

Key 6: Wait for 30 minutes, make the outside patch after dry.

Damage 3: A small broken seam

Here we use a sewing awl kit to repair the damage. To sewing it with a lock stitch in the whole process. It is as easy as you sew a broken bag or shoes.

The point is to make sure you start sewing from about a quarter-inch from the damaged area.

Sewing the whole broken area. You should have two ends of the thread on the same side. And finish off the stitch by securely tying the thread ends together.

Here is a video showing how to repair with a sewing awl kit.

Damage 4: Accidental injuries

Damage occurred suddenly when the party is going on. A small hole or tear occurs. You have no way to stop this party right away. It will turn into a disaster. At this moment, you need a repair tape.

Rapidly clean up the broken surface. Cut the round edge of the tape, peel off and stick it on the damaged position directly.

It temporarily keeps the damage from continuing. This tape repair method is not permanent. It suits the urgent situation only.

Once the crisis is gone. Go to fix it use the other 3 ways we learned from this article.

Last but not least, please send it to the fix company for the serious damage you cannot deal with in these ways.
