Inflatable Boat Internal Sealant Kit

Inflatable Boat Sealant Kit Stops Slow Leaks

 

This Inflatable Boat Sealant is specially formulated for use with inflatable boats, rafts and tow toys. This sealant forms a bond with the interior fabric of the inflatable stopping or "sealing" slow leaks and inhibits future leaks from developing. In one easy step, leaks are cured from the inside which are virtually impossible to find from the outside.

 

This Sealant is the only product of its kind which allows for future deflation of your inflatable (for storage, etc.) without the skin sticking to itself and making re-inflation virtually impossible. This is why this Sealant product has a 5-Star product rating and is used by the US Navy and Yachters worldwide since 1986. See customer pictures and testimonials below.

 

How It's Used:

  1. Deflate the boat.
  2. Inject the liquid sealant, equally distributed, into all the air chambers on your boat through the valves. Otr at least the ones you have slow leaks in.
  3. Inflate the boat.
  4. Turn the boat end over end and side to side to alloow the sealaer liquid to roll around inside the tubes, making sure that the entire interior is covered.
  5. It's sealed and as good as new!

 

The time you used to spend pumping up the dinghy every few hours or days you can now spend with your first mate, working on your tan, fishing or just relaxing.


Only one quart (1 bottle) is needed to seal up to a 12 foot boat unless you have many slow leaks. Read the "Usage Info" tab to calculate amounts required for bigger boats. If you have several slow leaks, consider buying 2 bottles and applying one coat, allow it to dry and then apply the 2nd coat. For larger boats, buy additonal units of the sealer. See the "Usage Info" tab to calculate amounts required for bigger boats.


Your inflatable can be even more reliable than when it was new. Don't sell it or discard it, use this sealant products to repair inflatable boats of all types.

PAINTING YOUR INFLATABLE BOAT OR MAJOR RESTORATION PROJECTS

If you want to paint your inflatabel boat to give it a nice new look, consider using our Top side paint.


If you need to restore your inflatable to cover abrasions, and add an extra layer of protection to the old fabric of your tubes, we recommend that you use our Liquid Rubber product first before you paint your inflatable with Top Side paint. This will make the surface of your inflatable like new. Many of our customers have used Liquid Rubber and our Top Side paint to repair and restore inflatables that were 10 to 15 years old. If your inflatabe boat has slow leaks (loses air over a day or 2) use our internal tube sealant. It works wonders.

 

To make you inflatable more reliable, leak free and good looking for the long-term, use our three step process:

(1) Seal It (with our internal sealant liquid to seal slow micro leaks)

(2) Re-Skin It (using the Liquid Rubber paint)

(3) Paint It (using Top side paint)


If you choose to do the 3-step process, buy everything you need in our Restoration Kit and save money overall.


 

Customer Pictures and Testimonials

 

You just saved me $2,500! That's what it would cost me to replace my Seaworthy hard bottom inflatable. Your Liquid Rubber on the exterior and Sealant on the inside make by boat perform and look like new. Thanks for products that live up to their claims. Capt. Jack Nolan Aboard "Whisper," Galveston TX

I have a 1973 Zodiac Mark 1 classic that has a Teak home built seating arrangement that lands on the top section of both air chambers. In the past someone had glued down some fabric on the tops of the chambers to reduce wear. Of course this is where the holes are, below this fabric, and these leaks could be seen with the bubble test. I purchased 1 bottle of this miracle liquid and followed directions. To my amazement this stuff worked on its first attempt like a dream. My 1973 Zodiac is back in the business holding air, no need to bump it up before use or daily like I was. What really surprised me is I can not see where the sealant has leaked out while sealing the holes. The stuff just worked and I again have full confidence in the boat. Thank you for such a great product!  Curtis

sponson tubes sealant repair

Hello, I just used your sealant for inflatables on the sponson tubes of a vintage Pakboat folding kayak and I am simply blown away by how easy it was and how well it worked. The sponsons are made of PVC coated polyester cloth and they were deflating within minutes even though I thought patching a few obvious pinholes would solve the problem. When I used your sealant the true nature of the failure of the original material coating became obvious -- the Inland Marine sealant oozed through multiple areas of the substrate fabric where the coating had obviously failed! I followed your simple directions carefully and now the sponsons have held full pressure for 24 hours! It would have cost me over $150 to replace them and now with less than $16 worth of your sealant the kayak is restored to full function. I have enough left over to use on my other boats -- I have 4 other folding kayaks with inflatable sponsons. Since this is a frequent issue with folding and inflatable kayaks and canoes, I have posted a recommendation for the sealant on my paddling forums. Attached is a photo showing how the sealant penetrated and sealed the areas on the sponson where the water and air proof original coating had failed from the inside. Great stuff!! Thank you! Kerry

Hello, Wow, what can I say? It really works! We have a 13-ft rib, apx 145 lbs, with three chambers, that is about 16 years old. The local repair shop told us there were too many leaks on the seams, and that it is "not worth the money to fix it." Two of us were able to roll the boat over and over doing one chamber at a time. Now, NO LEAKS! We thought it might take two or three bottles, but in our case, one worked just right! A big thanks. John R.S/V Indigo Hamlet

Hello, I have a Hutchinson Nautisport Speedyak from 1968 that I have owned since 1974.  It had not been used in a couple of decades because of a fairly severe leak in one tube (about 2 hours before it was unusable) and a minor leak (about a day and half before it was too soft) in the other tube. I couldn't part with it due to sentimental reasons. I took a chance and purchased your sealant kit.  I wasn't expecting great results given the age, and the severity of the leak.   After using your kit my boat is like new !!!   I brought it up to full inflation and it remained that way for over a month.  I have deflated and inflated several times and it's still perfect!  I couldn't be more impressed with your sealant!  Thank you for your time! David, Newport, MN

Hello folks, Just wanted to drop you a line to let you know I received my order, used it, and that stuff is awesome! The leak in my Coleman Lazy Spa Hot Tub inflatable was instantly located and before I could put a patch on the outside, the product sealed the leak from the inside. I initially did an extensive soap and water search and could not find the leak. Granted, I could have put the soapy solution in the inflatable and likely would have found the leak BUT, the soapy solution would not have found AND sealed the leak. Thank you guys for such an awesome product that's the real deal as advertised! Claude

I fish about 125 days a year and have broken four "National Fresh Water Fishing Hall of Fame" world records so it's very important for me to have a dependable boat. I took good care of my German Metzeler inflatable and it looked like new but three different sections developed numerous leaks. Several boat dealers told me Metzeler was out of business and one of the reasons was that the material they used often developed a form of fatigue that was incurable. They said throw the boat away and buy a new one. I was not convinced and further investigation led me to your Sealant Kit or should I say in my opinion your "Miracle Sealant Kit." After using your product my boat holds air perfectly. It's like having a new boat. Your Sealant Kit saved me from buying a new boat and at least $2,000. Bill Neavin Hemet, CA

What a product!!!! I've just recently used your Sealant kit and am amazed at the results. My ten year old West Marine inflatable now stays rock hard (better than it ever has). Now the only problem is the copious amount of water it takes on due to the almost total lack of rubber on the bottom. Therefore, I would like to order your Liquid Rubber kit to re-skin the bottom. If it works half as well as the Sealant I should end up with a brand new boat! Sean Lackey San Francisco Bay

I just used your Sealant Kit and does it work! It only took one application and the boat holds air just like a new one. The reason I'm writing is I have several friends who have the same problem with their inflatable. Can we buy the Sealant in larger quantities? Thank You, Dennis Klein Dingmans Ferry, PA

We host a family reunion at our lake house every year. I had just spent $300.00 on a 12 ft. towable for my nieces and nephews and naturally they tore it up the first day by putting a 2 inch gash in one of the air chambers. I had some of your Patch Kit left over from repairing my dingy and figured I would try it. What a product! The next morning the raft was as good as new! You couldn't pull the cut apart! The only question I have is do you sell this glue in a lipstick applicator for my sister-in-law? Bill Carlson Lake Lanier GA

Greetings from Kenya. I just used my last quart of Sealant and can of Top Side Paint on my 12 year old Avon. We started from Ft. Myers FL in 1979 and have been around the world twice. I think our Avon is more Sealant and Top Side Paint than dingy, but she still works and looks Bristol. Thanks for great products. Paul Stokes onboard Ulpyuas Kenya, East Africa

It's always a pleasant surprise to find a product that really does what it's supposed to do. Your inflatable boat Sealant Kit performs even better that your advertising said it would and my old formerly saggy inflatable is almost good as new again. Where I was having to pump it up almost every day, it now stays hard as a rock for weeks at a time. The porosity problem is solved. It's amazing, and it was so easy to do just by following the instructions. Congratulations on a great product. Next I'm going to try the Top Side Paint. Jack Turner Aboard Kalypso

 

Calculating How Much Sealant to Use With Boats Over 12 Foot
One quart of Sealant (1 bottle) is sufficient to seal small leaks on boats 12 feet long or smaller. On boats larger than 12 feet, there is a formula for calculating how much Sealant to use for each air chamber:

1. The basic rule is: 1/2 ounce of Sealant will cover 1 square foot of material.

2. The Formula for finding how many square feet of material there are inside your boat is: (Length of the Boat in feet) x 12 x 2 x (Diameter of the tube in inches) x 3.1416 -:- 288 = Number of ounces of Sealant needed to treat the boat. This number, divided by the number of air chambers gives the amount of Sealant needed in each air chamber.

EXAMPLE
A 15 foot long boat with 22 inch tubes and 3 air chambers:
15 x 12 x 2 x 22 x 3.1416 = 24,881.47 square inches total area. 24,881.47 -:- 288 = 86.5 ounces of Sealant will be necessary to treat this boat. Divide 86.5 by 3 air chambers and each chamber will require about 29 ounces. There is approximately 32 ounces in 1 quart.

About the Sealant

  • Sealant is use to seal leaks in your air chambers.
  • Sealant will fix leaks you can find and those difficult slow leaks you cannot find.
  • Sealant provides a strong bond that should last for years when applied per the instructions.
  • Inflatable boat repair is accomplished easily with our sealant.
  • If you cannot find the leak in your raft, kayak, tow toy, or dinghy you need to use this sealant.
  • It will seal the leak(s) and keep you inflatable firm for years to come.
  • This sealant can be use multiple times, so if your inflatable develops a new leak weeks or years from mow you can use the sealant again.

How Can Something So Thin Be So Strong?
The Sealant flows faster than water. The viscosity of the sealant was specially formulated by a chemist to repair inflatable boats and make them reliable in even rough seas. You might compare it to sheet of Kevlar. Kevlar can stop bullets, a 2 mil thickness of sealant can stop air up to 90 PSI. In tests, soccer balls were sealed and used in games. They were bounced on concrete and kicked hard without leaks. Since 1986 the sealant has been used by boaters around the world to repair inflatable boats of all kinds. The product is used by professional raft repair companies, US Navy Seals, and individuals for inflatable boat repair. Some manufactures even use this sealant to repair boats in their Quality Assurance Test. Slow leaks can be difficult or even impossible to find, our sealant will solve all you slow leak problems in minutes.

Using Sealant to Treat Seam Leaks

  1. When treating a boat for seam leaks, first locate the leak using the normal soapy water test.
  2. Inject Sealant into the air chambers in the normal manner.
  3. If the Sealant oozes out of the seam leak, immediately release some pressure by opening the air valve. DO NOT deflate the boat entirely, but keep enough pressure in it so that it keeps its shape.
  4. WIPE OFF THE EXCESS THAT OOZED OUT IMMEDIATELY AS IT WILL DRY VERY RAPIDLY and you will not be able to get it off except maybe with solvent.
  5. Let the boat stand for about 3 hours in order for the Sealant, to cure in the seam.
  6. After this time, re-inflate the boat and test with soapy water to see if the seam is completely sealed. If it is not, put only about ONE OUNCE of Sealant in the chamber and turn the boat so that the, Sealant again oozes out of the leak, then turn the boat so that the Sealant does not stay in that one spot. MORE IS NOT BETTER! It is better to repeat this process several times than to use too much Sealant in one application.

Using this process, we have seen an eight inch seam leak sealed in three tries. The leak was eight inches long when the Sealant was first applied. On the second treatment it was about three inches long. The third try sealed it completely.

Although it took some effort and some patience, it saved the boat.

 

Using Sealant with Larger Boats

Calculating How Much Sealant to Use With Boats Over 12 Foot
One quart of Sealant (1 bottle) is sufficient to seal small leaks on boats 12 feet long or smaller. On boats larger than 12 feet, there is a formula for calculating how much Sealant to use for each air chamber:

1.  The basic rule is: 1/2 ounce of Sealant will cover 1 square foot of material.

2.  The Formula for finding how many square feet of material there are inside your boat is: (Length of the Boat in feet) x 12 x 2 x (Diameter of the tube in inches) x 3.1416 -:- 288 = Number of ounces of Sealant needed to treat the boat. This number, divided by the number of air chambers gives the amount of Sealant needed in each air chamber.

EXAMPLE
A fifteen foot boat with 22 inch tubes and 3 air chambers
15 x 12 x 2 x 22 x 3.1416 = 24,881.47 square inches total area. 24,881.47 -:- 288 = 86.5 ounces of Sealant will be necessary to treat this boat. Divide 86.5 by 3 air chambers and each chamber will require about 29 ounces. There is approximately 32 ounces in 1 quart.


How to Treat a Larger Boat with Sealant
There are a couple of options available to those who own inflatable boats too large or heavy for one person to tumble. One option is to call several friends and ask their help.

  • Then deflate the boat and inject the Sealant in each air chamber as outlined in the standard instructions.
  • Re-inflate the boat to rigidity.
  • Have two friends on each end of the boat.
  • Raise the stern to about 45 degrees and hold for about 10 seconds.
  • Lower the stern and raise the bow for 10 seconds.
  • Turn the boat (rotate along its length) about five degrees and raise each end again.
  • Continue rotating the boat 5 degrees at a time and lifting both ends until the boat has been turned completely over.

THE SECOND METHOD IS EASIER AND CAN BE ACCOMPLISHED WITH ONLY ONE PERSON!

  • Place the boat to be treated flat on the ground.
  • Deflate the boat and add the Sealant following the standard instructions.
  • WITH THE BOAT STILL DEFLATED, walk the Sealant around the air chamber, that is, step on the air chamber while it is deflated pressing the top half of the air chamber firmly onto the bottom half.
  • Start at the valves and work your way to the ends until you are sure all the top half of the chamber has contacted the bottom half. An option to walking the boat is to use a garden type roller to help spread the Sealant.
  • When you are sure Sealant has made contact with the entire interior of the air chamber, walk it again!
  • Now you're ready to re-inflate the boat to RIGIDITY.
  • Wait 3 hours, then inflate the boat to full pressure and check for leaks.
  • In the unlikely event that there are still leaks, re-treat the boat using only 1/3 the amount used the first time. Make sure the Sealant gets to the leaking area. Do not allow the Sealant to pool in any one area. MORE IS NOT BETTER.
