Works in dry, wet & underwater

With Adiseal it is possible to seal a leaking gutter even if it’s raining outside as Adiseal works in dry, wet & even underwater. The exact location of the leak can be seen with the rain water and the leak can be fixed straight away.

With other sealants, a dry day would be required first to apply the sealant. Only once that sealant has been cured will you know whether that sealant has fixed leak or not. With Adiseal, the leak can be fixed immediately with a good long lasting seal.

To show how Adiseal works in the wet and seals instantly even underwater we carried out a demonstration. In the demonstration we cut a hole (250mm x 10mm) in a very large plastic box. We filled it with water and sealed the leak instantly with Adiseal even through the water was pouring out. The video can be also be seen on YouTube by clicking here – Adiseal demonstration video.

Waterproof Sealant

As Adiseal is waterproof, it can also be applied even underwater & adhere to the surface being applied to. This will allow Adiseal to seal a leak instantly even if the gutter is full of water.

Gap Filling Sealant

Adiseal has high gap filling properties, meaning it will seal even if the hole in the gutter is big where the leak is coming from or there is a big gap in the gutter joint. Adiseal will also avoid slumping when used in overhead applications due to it’s high gap filling property.

Over Paintable

Adiseal is available in the following colours: white, black, grey, brown & ultra clear. Adiseal can be manufactured in any RAL colour. It is also over paintable with most paints if you want a colour that is not available in the standard colours.

Tip – If the gutter is a non standard colour then paint can be mixed into Adiseal Ultra Clear to make it match the exact colour of the gutter. Use a piping bag, tube or cartridge to apply the custom coloured Adiseal.

Flexible Sealant

The flexibility of Adiseal allows for movement due to temperature & moisture changes as well as soaking up vibration, creating the strongest seal. The seal on a non flexible sealant will eventually fail because it will become brittle over time. If you want a seal to last a long time it’s best to use a flexible product like Adiseal.

UV Resistant

Adiseal can be used both indoors & outdoors and is UV resistant. Adiseal will not become dry, brittle or peel away due the UV radiation from the sun.

Virtually Odourless

Adiseal does not contain solvents or isocyanate meaning it does not have that harsh solvent smell that you get with other products. Other products containing solvents will require well ventilated area requirements for use. This is not a problem for Adiseal as is very safe & virtually odourless.

No Shrinkage or Cracking

Adiseal does not shrink as it’s not filled with solvents unlike other products. Other products are filled with solvents to make them cheaper to manufacture but this results in there being less active product in the cartridge. This causes the product to shrink as the solvents evaporate away. As Adiseal does not contain solvents, there is more active product in the adhesive sealant tube & therefore no shrinkage when you apply it.

Problem of using cheap products

One problem of using a cheap silicone sealant to seal a gutter or any other item is that the sealant will start to peel away from the surface before it’s cured. This is because of the sealant shrinking due to the solvent escaping from the cheap silicone sealant. This is the same problem when using a cheap adhesive that contain solvents leaving a weaker bond than better products like Adiseal.

As Adiseal does not any contain solvents, it provides a much stronger bond & better seal that will last lot longer than other products. Using cheaper products sometimes end up costing more as once they fail, you will have to remove the old product & re-apply the new adhesive & sealant.

EC1 Plus certified

Adiseal is certified EC1 Plus meaning it has the lowest certified VOC for adhesives & sealants.

Suitable for interior & exterior use

Adiseal is a high performance product that performs equally well when used as an interior sealant adhesive as well as an exterior sealant adhesive. It remains UV resistant, flexible & waterproof.

Gutter leak at joint

There are 3 main reasons for a leaking gutter.

  1. A hole in the gutter caused be debris falling into the gutter from the roof. This could be broke slate or tile.
  2. Blockage in the gutter stopping the water running down into the drain.
  3. Failure of the sealant on a gutter joint between two sections causing the gutter to leak at the joint.

Thoroughly clean the place where the sealant will be applied. Remove any old sealant, oil, grease, tar, dirt, dust & any other stubborn deposit with Adisolve solvent cleaner.

How to repair a gutter leak

  1. To find the hole where the gutter leak is coming from on a dry day, take some water with you in a bottle & pour it into the gutter.
  2. Make sure the area where the sealant will be applied is thoroughly clean by brushing away any debris that has fallen into the gutter from the roof. Remove any old sealant, oil, grease, dust, moss & any other dirt before applying the sealant. Adisolve solvent cleaner is the ideal product to remove oil, grease, tar, old sealant & other stubborn deposits.
  3. Once clean apply the sealant on the hole. Adiseal can be applied in the dry, wet & even underwater. With other sealants, that area will require drying first.
  4. Excess Adiseal can be removed using a thick cloth. Adisolve can also be used to tool the joint & help clean up excess Adiseal.
