Adiseal is a top choice for gutter sealant with exceptional performance and instant sealing. Its fast-acting formula provides reliable protection against leaks and water damage. Unlike other sealants, Adiseal can be applied in damp and wet conditions, saving time and enabling quick repairs on leaking gutters.

Adiseal stands out with its exceptional durability and weather resistance. It can withstand UV rays, temperature changes, and heavy rainfall, providing long-lasting performance and reducing the need for frequent reapplication.

Instant Sealing even in Rain

Adiseal is excellent for repairing gutter leaks & roof leak due to its instant sealing capability, which works effectively with various gutter & roof materials like plastic gutters. It creates an immediate, watertight seal upon application, efficiently stopping water leaks. Adiseal is specifically designed to perform well even in rainy conditions, making it invaluable for addressing gutter joint leaks and being a gutter seam sealer without the need to wait for dry weather.

In our demo video, we highlighted Adiseal’s capacity to seal underwater instantaneously. We simulated a leak by creating a 250mm x 10mm hole in a large plastic box, filling it with water, and applying Adiseal. Despite the initial water flow, Adiseal promptly sealed the leak. Watch the video to witness Adiseal’s impressive performance.

Waterproof Properties

Adiseal’s effectiveness in sealing gutter joints, gutter seams and roofs during rain is due to its exceptional waterproof properties. Its formulation creates a strong water-repellent barrier that prevents water from penetrating the sealed area. This means Adiseal maintains its sealing capabilities even in rainy weather, providing reliable protection against gutter leaks. Its waterproof adhesive and waterproof seal nature ensures the seal’s integrity, keeping your roof or gutters watertight and effectively diverting water away from your home.

Gutter repair & cleaning

For an effective seal on a leaking gutter joint, begin with a thorough cleaning. Eliminate old sealant and clear any roof debris using a brush, ideally a fine one, like a painting brush, to remove fine dust.

Before applying the sealant, ensure the application area is entirely clean. Use Adisolve solvent cleaner to remove old sealant, oil, grease, tar, dirt, dust, and stubborn deposits. Adisolve effectively deactivates most silicon-based sealants, simplifying their removal.

How to use a gutter sealant

How to use a gutter sealant

  1. Clean the gutter

    Start by thoroughly cleaning the gutter and downspout. Remove any debris, leaves, or dirt using a brush or a garden hose. It’s essential to have a clean surface for the sealant to adhere properly.

  2. Apply the sealant

    Apply the sealant using a caulk gun or an appropriate applicator directly to the areas requiring sealing, such as joints, seams, visible cracks, or gaps. Begin at one end of the gutter and proceed steadily with an even application to the other end.

  3. Smooth and shape the sealant

    After applying the sealant, use a putty knife or a gloved finger to smooth and shape it. This ensures even coverage, strong adhesion, and a tidy finish. Remove any excess sealant that may have spread onto the gutter surface.

  4. Allow for drying and curing

    Refer to the sealant’s instructions for the recommended drying and curing time, which can range from several hours to a day. During this period, refrain from exposing the sealant to water or extreme weather conditions.

  5. Inspect and test

    After the sealant has dried, check the gutter for any missed spots or areas needing further sealing. Verify that all joints and gaps are securely sealed. To test the sealant’s effectiveness, pour water into the gutter and observe for any leaks.

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.

Gutter type

Gutters can be made from a number of different materials. The most common materials used are PVC plastic gutters and metal. Gutters are also made from steel, copper, concrete, aluminum, zinc and other materials. Plastic gutters are cheap, lightweight and easy to work with. They are available in a number of different colours but the most common colours are white, black, grey and brown. Whatever sealant for gutters is used, it needs to provide good adhesion on the material for it to seal properly. Adiseal adhesive & sealant provides the strongest adhesion and sealing properties on a number of different materials.

Clear gutter sealant

Adiseal Ultra Clear can also be used as a clear gutter sealant. Just like the other Adiseal adhesive & sealant range, it will seal leaks in even in the rain. Adiseal is also available as a black roof & gutter sealant.
