Polar Black Leak Fix Spray - 13.5fl. oz - Waterproof Roof Sealant - Instantly Seals Leaks and Cracks, for Lasting Protection on Roofs, Drainpipes & Gutter Repairs- for Interior and Exterior Use

Great sealant my pond was over 30 years old. Sprayed the stuff on it brought it back to life highly recommend!

I think our leak is too bad for this stuff to work. It stinks to high heaven, wear a mask.

Smells strong definitely gets you dizzy.water resistant and its color is clear for the use. The performance of it is great easy to apply and ok value for the money.

Update-it has been raining all day and I mean pouring rain. There is no leakage from my window. No rain rolling down my wall🙌🏾 this stuff is the truth. I highly recommend. //This was so easy to use. I have a window that's not easy to reach. This spray reached where I needed it to reach. I put on 3 coats, let it dry 15 minutes in-between coats. Great value. It does have a slight smell but it goes away.

Especial

I tried the stuff. I thought it was quite thin paint and then it wouldn't really empty but lost the pressure to spray it out. Sorry, no pictures or video. It was an awkward place where I used it

I had a complaint on a product from this company and also a different company. The customer service from Polar did fix the issue. The other company is terrible. I will try Polar products again.

Worked great, had a leaky valve and it sealed it up!

Ich habe damit mein mysteriöses Wasserproblem gelöst. Es sickerte offenbar immer wieder durch kleinste Risse in einem in die Jahre gekommenen Kunststoffdach mit Hohlraum. Das Wasser lief dann in den Hohlraum und an den Seiten in die Wände. Mit dem Spray habe ich den Wassereinlauf gestoppt.

SATISFAISANT

Dichtet hervorragend

Wenn man die Regenrinne sauber und trocken vorbereitet, reicht 2 min rumsprühen mit kleinen Pausen, um den Ansatz zweier Rinnen-Teile wieder dicht zu bekommen.Weil das Klebematerial "klar" ist, habe ich auch einfach von unten draufgesprüht, nicht nur auf die Innenseite, hat beim ersten Versuch geholfen und jettz ca. 10 Regentage ausgehalten.Die "geflickte" Stelle ist von unten nicht zu erkennne, hält dicht und war einfach zu verarbeiten daher 5*

This helped to seal a few hairline cracks in some external rendering (bay window roof meets render) but beware - a few months later, it's started to discolour and there's now a yellowish tinge to the white render where it's been sprayed on! It's definitely not suitable for anything bigger than hairline cracks though, failing to seal joins in a bath edging.
