Strong Sealant
Strong Sealant Adhesive: Waterproof Adiseal Better Than Silicone
Adiseal extra strong sealant provides a high-performance seal instantly in dry, damp, wet and even underwater. It provides a strong watertight seal on many different waterproofing sealing applications. Adiseal has been shown to have the strongest mould resistance, strongest clarity retention in water and strongest adhesion in an independent adhesion strength test.
Adiseal’s instant sealing capability allows immediate testing with water, straight after application, allowing savings on labour costs. Being able to seal instantly also allows emergency repairs by promptly stopping leaks, even in wet conditions like rain. Its weatherproof resistance makes it suitable for both interior and exterior use.
What is the best strong sealant?
In our experience, Adiseal stands out as an exceptional, instant-sealing, and durable sealant. It has strong resistance to mould, retains its colour well in water, UV resistant, delivers a high-quality, watertight and durable seal.
Instant sealing
Adiseal demonstrates its immediate sealing capabilities, efficiently stopping leaks even with a significant flow of water. In a demonstration, a 250mm x 10mm hole was made in a plastic tub and filled with water. Adiseal immediately sealed the leak. Check out the video for the full demonstration.
Best mould resistant sealant test
To highlight Adiseal’s impressive resistance to mould, we conducted a test comparing it with other products. Each was applied inside clean plastic cups partially filled with water and covered to prevent external contaminants.
Mould resistance test result
In the image, Adiseal remained free of mould for an impressive 90 days, surpassing all other products even after being submerged in water for an extended period.
Clear strong sealant
Adiseal comes in various colours and a clear option. While some clear sealants claim transparency but appear cloudy upon application, Adiseal’s clear variant proved to maintain exceptional clarity when submerged in water, demonstrating its strongest transparency in our test.
Adiseal remained transparent after a continuous 16-day submersion in tap water, unlike the competitor’s clear product in the image that turned white. This demonstrates Adiseal’s superior underwater performance and clarity retention. The test involved sealants from different manufacturers placed in water-filled cups, and the image below showcases the results after 16 days.

In the test results, Adiseal stood out as the sole product that preserved its transparency both above and below the water surface. Unlike its counterparts, Adiseal consistently maintained its clear appearance regardless of the surrounding conditions.

How to use a strong sealant
How to use a strong sealant
- Surface Preparation
Ensure the surfaces are clean, dry, and free from dust, grease, or debris. Use a solvent or suitable cleaner to achieve this.
- Cut the Nozzle
Cut the nozzle to the size of the bead required.
- Apply the Sealant
Squeeze the trigger on the sealant gun to apply a continuous bead along the joint or area to be sealed.
- Smooth and Shape
Use a caulking tool or your finger dipped in soapy water to smooth and shape the sealant bead.
- Allow Drying/Curing
Let the sealant dry or cure according to the manufacturer’s instructions. Avoid disturbing or exposing the sealed area to moisture until the sealant has fully set.
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.
