How to apply outdoor sealants

Applying outdoor sealants requires careful attention to detail and proper technique to ensure a secure and effective seal. Here are some general steps to follow when applying outdoor sealants:

How to apply outdoor sealants

  1. Surface Preparation

    Thoroughly clean the surfaces to be sealed, removing any dirt, debris, grease, or old sealant. Use appropriate cleaning agents and tools, such as a wire brush or sandpaper, to ensure a clean and smooth surface.

  2. Masking

    Use masking tape or painter’s tape to protect adjacent surfaces or areas that should not come into contact with the sealant. This helps achieve clean lines and prevents unintentional spread of the sealant.

  3. Cut the Nozzle

    Cut the nozzle ensuring an appropriate-sized opening for the desired bead size.

  4. Apply the Sealant

    Apply steady pressure to the trigger or plunger. Start at one end of the intended sealing area and move along, ensuring a consistent and even bead of sealant. Maintain a smooth and uninterrupted flow, without gaps or interruptions.

  5. Tooling

    After applying the sealant, use a tool like a caulking gun or a specialized tool (e.g., a caulking tool or a putty knife) to smooth and shape the sealant. This step ensures a tidy and professional finish while promoting proper adhesion to the surface.

  6. Remove Excess Sealant

    Remove excess sealant. This helps maintain clean lines and prevents unsightly buildup

  7. Curing Time

    Allow the sealant to cure according to the manufacturer’s instructions. Avoid any contact or disturbance during this period to ensure proper bonding and effectiveness.

  8. Clean-Up

    Clean tools, equipment, and any accidental spills with appropriate solvents or cleaning agents as recommended by the manufacturer. Dispose of any unused or expired sealant following local regulations.

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.
