Sealing and repairing roofs and gutters

Soudal's waterproof coatings for instant repair of roofs and gutters is a protective coating that effectively seals gaps and cracks. Leaky gutters can cause further issues if left untreated such as causing moisture to seep into the surrounding structure and cause structural damage and mould. Untreated gutters can also cause the gutter to completely break leading to more money being spent further break.

How to fix a leaking gutter?

1. Clean and dry the roof gutter

Remove all dirt, grease and dust. To do this use a coarse brush and a cloth if necessary. Remove all traces of existing coating materials. Soudagum Hydro cannot be used in standing water.

2. Spread the Soudagum Hydro sealant

Put on the gloves supplied in the repair kit before using the product. Cut the Soudagum sausage open with a (snap-off) blade. Pour the liquid product into the mixing box supplied.

3. Start applying the product and the reinforcement membrane

Spread the first layer of the product on the crack. The product must be applied at least 1 mm thick. Then use the Soudatextile reinforcement membrane for extra strength. Apply this membrane in the first layer when it is still moist. It is best to cut the membrane to match the size of the crack. Then apply a second layer of Soudgum Hydro on top of the Soudatextile, again at least 1 mm thick

4. Repair done

The repair is rainproof 2 hours after using the product
