TIPS FOR USING 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 Inland Marine USA sealant. It will seal the leak(s) and keep you inflatable firm for years to come. Inland Marine USA 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.

OW CAN SOMETHING SO THIN BE SO STRONG?

Inland Marine USA Sealant flows faster than water. The viscosity of our sealant was specially formulated by our chemist to repair inflatable boats, inflatable SUP and make them reliable in even rough seas. You might compare it to sheet of Kevlar. Kevlar can stop bullets, a 2mm thickness of Inland marine USA Sealant can stop air up to 90 PSI. In test, we even sealed soccer balls and used them in games. Bounced them on concrete and kicked them as hard as we could without leaks. Since 1986 our sealant has been used by boaties 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 Inland Marine USA 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.


CAUTION

Remember. Repair of Inflatable SUP and inflatable boats, kayaks, rafts, dinghies, or tow toys is dependent on proper preparation of the surface area. If you do not clean your inflatable as instructed you are wasting your time and the products you have purchased. HUMIDITY CAN SERIOUSLY AFFECT THE QUALITY OF PATCHES, PAINT, LIQUID RUBBER AND LIQUID TEAR REPAIR PRODUCTS. BE SURE YOU ARE WORKING WITH A CLEAN AND DRY SURFACE. IF POSSIBLE TAKE YOUR INFLATABLE BOAT INTO A  ROOM WITH LOW HUMIDITY OR PERFORM THE REPAIR WHEN HUMIDITY IS BELOW THE MANUFACTURES RECOMMENDATIONS.

Using Sealant to Treat Seams:
Sealant will successfully treat SMALL seam leaks.  If you can visually see where the seam is separated, the leak is probably too large for Sealant to work and should be reglued. When treating a boat for seam leaks, first locate the leak using the normal soapy water test. Inject Sealant into the air chambers in the normal manner. 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. WIPE OFF THE EXCESS THAT OOZED OUT IMMEDIATELY AS IT WILL DRY VERY RAPIDLY and you will not be able to get it off at all except with TOLUENE and 220 grit sandpaper.

Let the boat stand for about 3 hours in order for the Sealant, to cure in the seam. 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 ( 30mls ) 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 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 or 15ml of Sealant will cover 1 square foot or 0.09m2 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 divided by 576 = 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.
Metric Conversions - ALWAY CONVERT YOUR METRIC MEASUREMENTS TO IMPERIAL TO USE THIS FORMULA
1 ounce = 29.6ml
1 inch = 25.4mm
3.28 feet = 1 metre
EXAMPLE: A 15ft boat with 22 inch or converted 4.56m with 559mm dia tubes and 3 air chambers. Always convert metric measurements into imperial for the formula to work: 15 x 12 x 2 x 22 x 3.1416 = 24,881.47 square inches total area. 24,881.47 divided by 576 = 43.2 ounces converted equals 1280ml of Sealant will be necessary to treat this boat. Divide 43.2 or 1280ml by 3 air chambers and each chamber will require about 14 ounces or 427ml. It is recommended that you plan on two applications; use about 8 oz or 237ml the first time and about 6 oz or 190ml for the second treatment.


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. (When choosing this option, always remember the Cardinal Rule of Boat Repair: When you're out of beer, you're out of friends.)

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. (Now you're management.) 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! (Your friends are now casual observers...they can furnish their own beer.)

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.
