Why choose Adiseal waterproof sealant?
Adiseal industrial strength waterproof sealant provides a long lasting waterproof seal. It excels in instantly sealing leaks in dry or even in challenging wet conditions like rain. In our demonstration video below, we sealed a large 10mm by 250mm hole in a water-filled plastic tub instantly by applying Adiseal underwater sealant, sealing the leak immediately even with water pouring through the hole.

Best mould resistant sealant
In our tests evaluating mould resistance of various sealants, Adiseal emerged as the top performing sealant. We applied the various sealants in clean plastic cups, filled them with tap water, covered them and left them for several days. Despite prolonged exposure to the water, Adiseal sealant demonstrated the strongest resistance to mould growth compared to other products tested.
What is the best clear waterproof sealant?
Adiseal Ultra clear waterproof sealant lives up to its name, staying genuinely clear unlike some alternatives like silicone sealants that are cloudy on application. Unlike cheaper silicone sealants that say clear on the packaging but are cloudy instead on application, Adiseal Ultra clear waterproof sealant remains crystal clear, whether dry or wet, making it the superior choice.
In the image below, we conducted a test to demonstrate Adiseal Ultra Clear’s ability to maintain its clear appearance even after extended submersion in water.
Adiseal Ultra Clear has strongest colour retention in water
Colour retention test of clear waterproof sealant
We tested the clear waterproof sealants ability to keep clear by applying them inside new plastic cups. We then filled the cups halfway with tap water, covered, and kept under identical conditions for several days.
Adiseal top in colour retention test
After several days of being submerged in the same water, Adiseal outperformed competitors, staying clear both above and below the waterline. In contrast, competitor waterproof clear sealants turned white below the waterline. As can be seen in the image above, 1 competitor sealant also turned white above the waterline.
How to apply a waterproof sealant
How to apply a waterproof sealant.
- Clean the 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.
- Cut the Nozzle:
Cut the nozzle of the sealant tube making an opening that matches the desired bead size.
- Apply Sealant:
Apply a steady, even bead of sealant along the intended joint or area. Maintain consistent pressure for a uniform application.
- Smooth the Bead:
Use a caulking tool, spatula, or your finger (wearing a glove) to smooth and shape the bead, ensuring good coverage and a neat finish.
- Cure Time:
Allow the sealant to cure as per the manufacturer’s instructions. This could take several hours to a day, depending on the product and environmental conditions.
- Clean Excess:
While the sealant is still wet, wipe away any excess with a damp cloth or sponge. If the sealant has dried, carefully trim away excess using a utility knife.
- Test the Seal:
Test the sealant’s effectiveness by applying water to the sealed area after it has cured. Unlike some sealants, such as Adiseal, which can be tested immediately after application, even before full curing.
Tip: To store Adiseal once opened, leave about 1cm worth of product out of the nozzle and store the tube upright in a cool dry place. Adiseal requires moisture for it to cure. The exposed part out of the nozzle will cure creating a cap. To re-use Adiseal, pull the cured part out or cut the nozzle until the uncured part is reached.
Internal and external weatherproof sealant
Adiseal is a versatile industrial strength sealant ideal for both indoor and outdoor use, excelling as a weatherproof sealing solution for various applications. Its high UV resistance, flexibility, and ability to withstand high temperatures make it perfect for outdoor sealing projects. Additionally, it cures underwater, prevents mould growth, and sustains adhesion when exposed to water, making it an exceptional choice for instant sealing in rainy conditions, particularly for roofs and gutters. Whether its for indoor applications or exterior waterproof sealant applications, Adiseal provides a high-performance water resistant seal.
Permanent submersion
Adiseal can seal and bond underwater but isn’t designed for constant submersion. When using Adiseal to affix a tile in a pool filled with water, it’s crucial for the tile and grout to act as a barrier, preventing water from reaching the adhesive after installation. Adiseal can be suitable for such applications, even in pools permanently filled with water.
What types of surfaces do waterproof sealants work on?
They can be applied to a number of different material surfaces including wood, metal, concrete, stone, plastic, glass, ceramics, brick and many more.
Waterproof sealant for wood
We demonstrated Adiseal’s exceptional waterproofing ability on wood by applying it to wood and brick surfaces in dry, damp, and wet conditions. This showcased its strong adhesion and weather resistance, depicted in the accompanying images.
Waterproof sealant for plastic
For a versatile waterproof sealant suitable for various materials, including plastic, particularly PVC, Adiseal provides a high-performance seal. It is however not recommended for use on certain plastics like polypropylene, polyethylene or polyurethane.
Waterproof sealant for metal
Adiseal is a versatile waterproof sealant for metal as well as other materials. Prior to application, it’s essential to clean the metal surface thoroughly by removing any oil, grease, or rust to ensure a long-lasting seal on metal.
Waterproof sealing of electrical boxes
Adiseal is suitable for waterproofing the outside of electrical connection boxes and electrical junction boxes depending on the type of material the electrical box is made from. It can be used to seal the holes of the box and also seal the joints between the box and the lid.
To fill the box with a waterproof sealant, a suitable product needs to be used. Our IP68 rated IPGel Duo and IP67 rated IPGel Mono products are re-enterable electrical waterproof gel products that are capable of withstanding high voltage.
Colours
Adiseal adhesive and sealant is available in the following colours:
- White adhesive and white sealant
- Black adhesive and black sealant
- Grey adhesive and grey sealant
- Clear adhesive and clear sealant
- Brown adhesive and brown sealant
Adiseal can also be manufactured in any RAL colour.
Can you paint over waterproof sealant?
It is also possible to paint over Adiseal once it has cured. It is recommended to test in a small area before painting.
Waterproof adhesive glue
As well as Adiseal being a great waterproof sealant, it is also an excellent waterproof adhesive glue. It will provide a strong, durable, flexible and waterproof bond on many different construction materials.
