Polar Specialist Coatings Premium Leak Seal Clear Paint - 500ml - Instant Waterproof Roof Sealant - Ideal for Leaks, Cracks & Roof Repair - Concrete, Brick, Metal, Drainpipes & Gutters - Easy to Apply

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.

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

A friend was helping with my barn roof. He told me I needed to get something for the fiberglass panels that were 45 years old. I picked this out because it sounded like it would work. He started painting this on one of the panels and yelled down, "This is great stuff! Where did you get it?! I can't believe how good this works!" It darkened the panels, but the same light came in from them inside the barn. A super coating! You must be very careful when using this because the vapors will do a job on you if you are not careful. Good masks and a nice breeze work perfect.

Use as per instructions and it works very well. Good product decent price no muss no fuss

Wir haben einen dünnen Riss in einem Spülbecken der Firma Schock, nach Anleitung habe ich dreimal im Abstand von 20 Minuten auf den Riss gesprüht, nach zwei Tagen lief allerdings wieder Wasser durch. Das ganze habe ich zwei Tage später wiederholt, das ist jetzt vier Tage her und seitdem ist kein Wasser mehr durchgekommen – hoffe das bleibt. Wichtig ist, wenn man es in der Wohnung wie wir hier in der Küche anwenden, auf jeden Fall gut lüften. Während des aufsprühen hatte ich Gummihandschuhe getragen, eine Sicherheitsbrille sowie eine FFP2 Maske an.
