Waterproof Sealant
Waterproof Sealant: Adiseal Strong Water Resistant Seal
Adiseal, a high-performance waterproof sealant, instantly seals in dry, damp, or wet conditions, offering a robust weatherproof seal to prevent water from infiltrating materials. Outperforming products like silicone sealant mastic, Adiseal excels in sealing dry, damp, wet, and even underwater situations, making it suitable for indoor, outdoor projects, and emergency leak repairs. It’s available as a clear waterproof selant and various colours.
Instant leak sealing
Adiseal waterproof sealant excels in instantly sealing leaks, even in challenging situations. In the demonstration video below, Adiseal sealed a large 10mm by 250mm hole in a water-filled plastic tub, applied underwater, sealing the leak immediately.
Best mould resistant sealant
Adiseal stood out as the sealant with the strongest mould resistance in our tests. We applied various sealants and mastics to clean plastic cups and submerged them in tap water for several days. Even after this prolonged exposure, Adiseal remained the most mould-free among the tested products.
Clear waterproof sealant
Adiseal Ultra clear waterproof sealant lives up to its name, maintaining a genuinely clear appearance unlike some alternatives that turn cloudy upon application. Unlike cheaper silicone sealants that claim clarity but often cloud up, Adiseal Ultra Clear stays crystal clear, whether dry or wet, making it the superior choice for clarity.
We conducted a test demonstrating Adiseal Ultra Clear’s ability to retain its clear appearance even after prolonged submersion in water.
Adiseal Ultra Clear has strongest colour retention in water
Colour retention test of clear waterproof sealant
We tested the colour retention of clear waterproof sealants and mastics by applying the products to new plastic cups. These cups were filled halfway with tap water, covered, and maintained under identical conditions for several days.

How to use waterproof sealant
Details of how to use 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 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 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.
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.
Waterproof sealant for wood
We showcased Adiseal’s superior performance as a waterproof sealant on wood by conducting a demonstration. Applying Adiseal to wood and brick surfaces in dry, damp, and wet conditions revealed its strong adhesion, providing exceptional waterproofing and weather resistance, as shown in the accompanying images.
Waterproof sealant for plastic
Adiseal is a versatile waterproof sealant suitable for various materials, including plastic, particularly PVC. However, it’s not recommended for use on certain plastics like polypropylene, polyethylene or polyurethane.
Waterproof sealant for metal
Adiseal is a versatile waterproof sealant effective on various surfaces, including metal. 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.
Paint on waterproof sealant
You can use paint with Adiseal waterproof sealant. For oil or solvent-based paints, conducting a small area test is wise. Apply the sealant to a disposable item, let it cure, then apply the paint, observing if any peeling occurs. While most paints work fine with Adiseal, testing ensures compatibility, especially with certain types.
Adiseal can be manufactured in any RAL colour.
