Frequently Asked Questions About Adiseal Ultra Clear Adhesive Sealant
Is Adiseal Ultra Clear truly transparent or will it turn cloudy?
Adiseal Ultra Clear is engineered to be genuinely crystal clear. Unlike many clear silicone sealants that appear cloudy or white upon application, Adiseal remains 100% transparent. In independent testing, Adiseal was the only product to stay completely clear both above and below the water line, while competitors turned milky white.
Does Adiseal Ultra Clear stay clear when used underwater?
Yes. Adiseal Ultra Clear has superior color retention and does not turn white when submerged in water. It is ideal for emergency underwater repairs, such as leaks in ponds or pools. While it can be applied and will bond underwater, it is not designed for permanent structural submersion without a secondary barrier like grout or tiles.
How strong is Adiseal Ultra Clear compared to clear silicone?
Adiseal Ultra Clear significantly outperforms traditional clear silicones in both adhesive strength and flexibility. As a high-performance MS polymer, it provides a professional-grade bond on almost any material, including glass, metal, and plastic. It is virtually odorless, solvent-free, and has been proven as the strongest adhesive in independent tests.
Professional Tip: To seal leaking gutters in heavy rain, apply Adiseal Ultra Clear directly into the standing water. It creates an instant waterproof bond and seal that standard silicones cannot achieve.
How do you apply Adiseal clear adhesive sealant for the best results?
How to Apply Adiseal Adhesive Sealant for a Professional Bond
Prepare and Clean the Surfaces
For the strongest possible bond, ensure surfaces are free from dust, grease, and loose material. While Adiseal works on wet surfaces, removing heavy debris first improves initial contact. If applying to metal, a quick wipe with a solvent-based cleaner is recommended.
Prepare the Adiseal Cartridge
Cut the top off the threaded plastic stud on the 290ml cartridge. Screw on the included nozzle and cut it at a 45-degree angle. For heavy bonding, a wider opening is better; for fine sealing, keep the opening small. Place the cartridge in the caulking gun / sealant applicator.
Apply the Adhesive or Sealant
For Bonding: Apply Adiseal in vertical “strips” (beads) rather than blobs. This allows air to circulate for faster moisture-curing. Press the two materials together firmly.
For Sealing: Apply a continuous bead into the joint. For underwater repairs, apply the sealant directly into the leak; the MS-polymer technology will displace the water to create an instant seal.
Tool and Finish the Joint
Smooth the sealant immediately after application. Use a profiling tool or a finger dipped in a soapy water solution. Adiseal remains flexible and does not shrink, so it will maintain its shape as it cures.
Allow for Curing Time
Adiseal has a high initial grab. Under normal conditions, it skins over in 10–20 minutes and is recommended 48 hours to fully cure.
Other colours Adiseal adhesive sealant is available include: White, Black, Grey and Brown.
