Details of benefits

Works in dry, wet & underwater

This attribute proves invaluable, particularly in urgent situations such as sealing a leaking gutter. Unlike many other products that necessitate a dry surface for application, Adiseal excels in emergency repairs.

Adiseal also serves as an exceptional black waterproof sealant, enabling its application in scenarios where other sealants may fall short. Its waterproof properties not only allow for effective sealing but also facilitate immediate testing of the seal, a feature not commonly found in other sealants. Moreover, Adiseal proves to be a reliable choice for automotive purposes.

Waterproof sealant available in different colours including black.

Over Paintable

Adiseal offers a wide range of colour options, including white, black, grey, brown, and ultra-clear. Custom manufacturing in any RAL colour is available for specific needs. Adiseal is compatible with most paints, simplifying the over-painting process. For solvent-based and oil-based paints, compatibility testing is recommended. Lightly sanding the surface can enhance paint adhesion. Wait for the full 48-hour curing time before painting over Adiseal to ensure the best results.

Tip – Own paint colour can be mixed into Adiseal Ultra Clear to make an adhesive & sealant match the exact colour required. Use a piping bag, tube or cartridge to apply the custom coloured Adiseal.

 

Virtually Odourless

Adiseal sets itself apart from other sealants by eliminating the strong solvent odor commonly associated with them. This distinction is due to Adiseal’s solvent and isocyanate-free formulation. While adequate ventilation is often necessary when using other sealants, Adiseal eliminates this concern, offering a user-friendly experience without compromising on performance.

 

Solvent Free

Adiseal black sealant adhesive is crafted without solvents, ensuring enhanced safety when working with delicate materials that are susceptible to solvent damage. Polystyrene is particularly vulnerable to solvents, and it is occasionally utilized in bath panels, making it prone to harm from black bath sealants containing solvents. Fortunately, Adiseal poses no threat in this regard, making it an excellent choice for applications such as black bath sealant where the protection of sensitive materials is paramount.

 

No Shrinkage or Cracking

One common issue with solvent-based sealants is their tendency to shrink during the drying process. This shrinkage can result in a weaker seal as the sealant pulls away from the surface. While solvent-based products may be more cost-effective to produce, this often means that there is a smaller amount of active product inside the tube, potentially affecting its overall performance and durability.

 

EC1 Plus certified

Adiseal boasts the lowest Volatile Organic Compound (VOC) content among its counterparts and holds the prestigious EC1 Plus certification.

 

Black kitchen sealant

Adiseal has obtained the ISEGA certification, signifying its suitability for use in food preparation areas. With its certification, Adiseal emerges as the perfect choice for a black kitchen sealant, ensuring a safe and reliable solution for food-related applications.

 

Interior & exterior use

Adiseal demonstrates its versatility by being suitable for both interior and exterior applications. Its exceptional performance surpasses that of specialized products, making it a superior choice for various sealing needs. Whether you require a black worktop sealant or a roof sealant, Adiseal delivers outstanding results in both scenarios.


How to use a black sealant

How to use a black sealant

  1. Prepare the surface

    Ensure that the surface you are sealing is clean, dry, and free from any dirt, dust, or loose particles. Use appropriate cleaning methods and tools to prepare the area.

  2. Cut the nozzle

    Cut the nozzle of the black sealant. Make sure to cut a small opening that matches the desired bead size.

  3. Apply the sealant

    Hold the caulking gun at a 45-degree angle to the surface and slowly apply a consistent bead of black sealant along the desired area. Use steady pressure on the gun trigger to control the flow of the sealant.

  4. Tool the sealant

    After applying the black sealant, use a caulk smoothing tool to smooth and shape the sealant bead. This helps create a neat and professional finish.

  5. Cleanup

    Any excess sealant should be wiped away using a damp cloth before it dries. Avoid smearing or spreading the sealant outside the desired area.

  6. Allow curing time

    Follow the manufacturer’s instructions to determine the recommended curing time for the black sealant. This can vary depending on the specific product and environmental conditions.

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.
