Adiseal is such a great product that it can be used as a dry or wet sealant, underwater sealant & even underwater glue. Most sealants require the surface to be dry for it to stick to the surface. With Adiseal, it can be applied to dry, damp, wet surfaces and even underwater. This makes Adiseal ideal for carrying our permanent and emergency repairs in pools, boats, buckets, tanks, tubs, leaking gutter, felt roof and many other items. This article will also look at how to seal underwater and how to glue underwater.
Sealants suitable for use underwater
As most sealants have to be applied to dry surfaces, it can make the job much longer to complete if working on something that contains water. The water will need to be removed first to be able to apply the sealant. This can take a long time where there is a lot of water, like in pools. Even if the sealant is applied to a dry surface, not all products are suitable at sealing underwater when the water is reintroduced. The products might not stay bonded to the surface underwater.
Adiseal is best underwater sealant
Adiseal waterproof sealant and adhesive can seal a leak even underwater. To show how good Adiseal is at working underwater, a 10mm by 250mm hole was cut into a large tub. It was then filled with water. Even with the water pouring through the large hole, Adiseal was able to seal instantly.
For a product to successfully seal underwater, it also needs to cure underwater, resist mould growth as well as stay stuck to the material surface.
Best mould resistant sealant test
To find out what is the best underwater sealant, we carried out several tests including a mould resistance test. The test was carried out by applying different sealants inside new plastic cups. The cups were then filled half way with tap water. Each cup was then covered and kept in the same conditions, to be fair to all the products being tested. The best sealant was Adiseal as it had the strongest mould resistance from the sealants tested. This can be seen in the image below.
Mould resistance test result
Even after 90 days of being underwater in the same tap water, both the sealant & water are still very clear in the Adiseal cup.
Adiseal Ultra clear sealant & adhesive is one very clear sealant. Other sealants might say clear on the tube but when you apply them they are instead cloudy or have coloured tint. Cheaper silicone sealants tend to be very cloudy, almost white in colour when you apply them instead of being clear.
Adiseal Ultra Clear has strongest colour retention underwater
Adiseal also has the strongest colour retention when underwater. As the image shows, the competitors clear product has turned white whereas Adiseal stayed clear.
Colour retention test
The colour retention test was carried out with a number of clear sealants from different manufacturers. Each product was applied inside new clean plastic cups, filled half way with water, covered & kept them in the same conditions.
Colour retention test result
Adiseal was the only product to stay clear above & underwater, making it ideal for use as an underwater clear sealant & glue.
It can also be manufactured in any RAL colour.

How to seal underwater
Details of how to seal underwater.
- Pick suitable sealant
To seal underwater, most sealants are not suitable. Adiseal will be able to seal in dry, damp, wet and underwater.
- Clean surface
To get a good long lasting seal, making sure the surface is clean is vital before applying the sealant. If there is any grease, dirt or mould, clean that first before applying the product.
- Apply sealant
With Adiseal simply apply it to the area that requires sealing.
- Seals instantly
Although Adiseal can take 24 to 48 hours to fully cure, it should be able to seal straight away.
- Remove excess
Remove any excess sealant to get a good clean finish. This can be done whilst the underwater sealant has not cured yet. If the sealant has already cured then cut the excess off with a sharp knife.
Adiseal seals, grabs and bonds in dry and wet conditions. The grab properties and wet sealant properties of Adiseal, were demonstrated by pouring water on bricks first. On this wet surface, the wet sealant was applied, grabbed and lifted with another brick immediately. This is just one of the reasons why Adiseal is also a great wet weather sealant.
Adiseal is both sealant and adhesive in 1 product. For this reason it is also a great underwater glue. As shown above, Adiseal grabs instantly in the wet. It also cures in wet and provide the strongest underwater glue bond. In an independent adhesive strength test, Adiseal was way ahead of competitor products.

How to glue underwater
- To glue underwater requires a special adhesive that can be applied underwater, cures underwater and the joint remains strong in water. Adiseal waterproof adhesive & sealant is able to glue underwater.
- Making sure both surfaces are thoroughly clean will get the best bond. Clean any grease, dirt or mould from the surface of the items that require sticking underwater.
- Apply the underwater glue to 1 surface and push the other item on firmly.
- It can take 24 to 48 hours for the adhesive to cure so temporary supports might be required to hold the items in place.
- Remove any excess to get a clean finish.
