Clean stick with rubbing alcohol for optimal adhesion.

For butyl tape, push down closely against leaks.

Reapply sealant if needed.

​​Preventive Gutter Sealing Mistakes​​

❌ ​​Not prepping the surface​​ – Sealant won’t adhere to dirty or rusty gutters.

❌ Applying in cold or damp weather​​ – It is it important that the sealant has completely dry condition to cure.

❌ ​​Using an inappropriate sealant​​ – Silicone is better for flexibility; polyurethane for metal.

❌ ​​Too Thickly applied sealant​​ – Thicker the application the longer it takes to dry and it will produce cracks.

​​Expert Maintenance Tips​​

Check gutters for cracks twice a year (spring & fall).

​​Reapply every 5-10 years​​ (silicone lasts longest).

Use gutter guards – Though it won’t completely keep debris out, it’s a great way to lessen debris build up and prevent leaks.
