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

Pretty good
Did quite a good job on a shed roof. I used it outside and inside on the joints. Some leakage later, but only in one place, so I'll just use silicone sealant to fix it.
User
Brilliant
It worked, nothing else did, and I was despairing at not being able to stop rain water coming into my static van. I sprayed this on the area when it was bone dry, and, what can I say? No more water ingress.

Not particularly very good not worth buying
Doesn’t work very well

Gutter sealant
Easy to use, sealing joints in the gutter, only need the rain to test it out. Not to much rain in summer though, could use the hosepipe but I’ll wait.
User
Decent
Good for small leaks

Convenient spray format for targeted sealing
The spray format offers a convenient approach to targeted sealing jobs, although surface compatibility and preparation deserve careful attention.

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.

As advertised

Schutzbrille, FFP2 Maske und Gummihandschuhe nicht vergessen
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.
