Underwater magic sealants are a type of adhesive substance that can be used to seal and repair objects or surfaces underwater. These sealants are specifically designed to work effectively in wet environments and provide a strong bond even when submerged in water. One common application of underwater magic sealants is in the construction and maintenance of swimming pools. Since pools are constantly exposed to water, it is essential to have a reliable sealant that can mend any leaks or cracks underwater. Underwater magic sealants can be applied directly to the damaged area without the need for draining the pool, saving both time and money. Another use for underwater magic sealants is in marine environments, such as boat repair or aquarium maintenance.
It filled just fine - Thick enough to fill that 3/16” gap without running.
I am, however, a life-long builder of radio-controlled model airplanes and I ve been using epoxy since it first became available, albeit in much smaller proportions. GelMagic exhibits exceptionally high peel strength and employs a state of the art, two-phase epoxy morphology, which creates an adhesive bond that is tougher, more resistant to embrittlement and has better elevated temperature properties than other room temperature cured epoxy adhesives.
Another use for underwater magic sealants is in marine environments, such as boat repair or aquarium maintenance. These sealants are ideal for fixing leaks or bonding materials in areas that are constantly in contact with water. Their ability to adhere to various surfaces, including metal, glass, or plastic, makes them versatile and suitable for different types of repairs.

I had put up a 12’ x 20’ screen room to serve as a boat shop, constructed a strong back, bought a pile of plywood, and begun to measure and cut out bulkheads … so it was time to purchase some adhesive. About this time Chuck and Sandra added Gel Magic to their line and it seemed like the right thing to use. A day after I ordered I got a confirmation from Sandra, a couple of days after that and UPS dropped it off at my home, and the next day after that Chuck sent me note asking me for a short product review.
After all the help folks on Duckworks have given me designing my 15’ Pocket Cruiser “Wanderer”, how could I refuse. Except. The good news is that I’ve never built a boat before so I have no preconceived notions to bias my opinions. The bad news is that I’ve never built a boat before so I have no preconceived notions to bias my opinions .. or experience to compare with. I am, however, a life-long builder of radio-controlled model airplanes and I’ve been using epoxy since it first became available, albeit in much smaller proportions. And among other things that I knew was that most epoxies are “runny” .. not quite water-like, but pretty thin. The thicker viscosity purported with Gel Magic appealed to me. It was time to give it a try.
This is what it looks like in the bottle.

The correct ratio is two parts resin to one part hardener .. And that raises the first point about using GelMagic. The resin is VERY thick and pours VERY slowly and settles very slowly into the mixing cup. The hardener is much thinner, about what I’ve experienced with other brands so it is easy to pour too much. A well marked cup will help, but it takes attention. Happily, I see no real difference in results in the batches where I used too much hardener.
The second point is so common that I might not have mentioned it. It is easy to mix too much at first, until you learn to judge how much you need for each joint. Here are a couple of shots that illustrate my first tries:
The first shows GelMagic used to fill an errant saw cut.
It filled just fine - Thick enough to fill that 3/16” gap without running.
The third shot shows the bulkheads ready to glue.
With latex gloves on and working with the epoxy, I didn’t take any close ups of the joining process itself, but it’s pretty straight forward to mix a batch, spread it on the parts and put them together. I’ve used a few brass wood screws every time to assure a tight joint. The cured GelMagic is so strong that they’re probably not necessary if you clamped parts securely as you joined them. Working time is about the 10 minutes the directions specify and it sets in about 20 to 30 minutes. I haven’t worked with any of the pieces until the next day but you probably could after a couple of hours if you didn’t stress any of the joints.
The other major joint to illustrate is where the transom is joined to the bottom. This is four foot long by 1” and not fully beveled, so there is a press fit across the back, but about ¼” gap across the front.
As you can see, it’s a clean, strong joint.
After several days the GelMagic is hardened like steel … well, maybe more like aluminum. It will sand with effort and cuts with a jigsaw but is very tough and difficult to cut with a utility knife. It pays to work carefully, because spots that remain and need to be taken off take some work - The wood will give before the GelMagic.
The bottom line is that I’ve just ordered a second batch. I tried Gorilla Glue in just a couple of non-critical places for comparison. There’s no contest. The Gorilla Glue is runny and seems to expand and sets up with air bubbles where it flows out of a joint. I can’t speak about other adhesives, of course, but I don’t see a need to use anything else than GelMagic. This is hardly a professional review but if you have questions I’ll try to respond below.
Oh yes .. If you’ve been reading Duckworks this year you realize that these parts are for my 15’ pocket cruiser Wanderer, but some of you may be new to this great site, or maybe just ‘Googled in “. You’ll find the articles under “Designs” from the main page. Since these shots the bottom is cut, transom, bulkheads and stem glued in place, and the stringers added. It’s beginning to look like a boat.
Good boatbuilding .. Good sailing.
Underwater magic sealants are typically easy to use and apply. They come in either a paste or a tape form, which can be applied directly to the surface that needs sealing. Once applied, the sealants start to cure and form a waterproof barrier. Depending on the specific product, the curing process can take anywhere from a few minutes to several hours. One important aspect to consider when using underwater magic sealants is their compatibility with the materials being repaired. It is crucial to choose a sealant that is suitable for the specific surface or material, ensuring proper adhesion and long-lasting results. Additionally, following the manufacturer's instructions and guidelines is essential to achieve the best possible outcome. Overall, underwater magic sealants offer a convenient and effective solution for sealing and repairing objects or surfaces underwater. With their ability to work in wet environments and provide a strong bond, they are widely used in various industries, particularly in swimming pool construction, marine repairs, and aquarium maintenance..
Reviews for "Unlocking Treasure Troves: The Use of Underwater Magic Sealants in Salvage Operations"
1. Emily - 1 star
I was really excited to try the "Unferwatr magci selant" after seeing it advertised as a revolutionary product. However, I was extremely disappointed with the results. The sealant did not adhere well to the surfaces I applied it to and started peeling off within a few days. Additionally, it did not provide the durable, waterproof seal that it claimed to. I ended up having to remove the sealant and redo the task using a different brand. Overall, I would not recommend the "Unferwatr magci selant" as it failed to live up to its promises.

I have used many different sealants in the past, but the "Unferwatr magci selant" was by far the most disappointing one. The application process was messy and difficult, with the sealant constantly dripping and spreading unevenly. It also had a strong chemical smell that lingered for days. Despite following the instructions carefully, I found that the sealant did not provide a long-lasting bond and started showing signs of wear within a few weeks. I would not purchase this product again and would advise others to look for better alternatives.

I bought the "Unferwatr magci selant" with high hopes, but unfortunately, it did not meet my expectations. The consistency of the sealant was too runny, making it hard to apply evenly. Even after allowing it to dry for the recommended time, it remained tacky and attracted dirt and dust. The sealant also did not hold up well against moisture and started to peel off in areas where it had been applied. Overall, I found this product to be ineffective and would not recommend it to others looking for a reliable sealant.
