JENOLITE Directorust Radiator Enamel Spray Paint | SILVER | Gloss Finish | Resistant to 130ºC | Durable, Scuff Resistant, Non-Yellowing Radiator Paint | No Primer Needed | 2 x 400ml

I have used this for a few different purposes now and it really does work well! The first use was very much more it's intended usage - spraying on a gutter join that had started dripping. No more drips! The second use was on a campervan conversion, where the vent/fan had developed a small leak in the mastic/silicone sealant. Generous reapplication of new sealant and topped with Jenolite completely waterproofed the seal and it has survived even the most horrendous downpours without any worry of water ingress.The spray comes out pretty wet and gasses off a lot when it lands, but becomes sticky almost immediately and you can tell it's working it's way into any gaps. I've found that a couple of coats are best applied, and definitely benefits from completely dry surfaces and conditions while it cures, but once it's dry water is going to have a really hard time getting past it.

Not very effective actually

Having just moved into a new home, which had new gutters and down pipes, I was surprised to find that the rear gutter was leaking badly from a joint when it was raining, so bought this product and used as instructions, and it solved the issue very well indeed. Would recommend this product.

Easy to use but didn't stop my garage from leaking used between the wood of the garage wall and concrete floor. First rainfall and it still leaked

We have a caravan with a cracked skylight window. The cracking was probably caused by continues exposure to the element's. To replace the skylight I have been quoted £800 to £900!!I removed the skylight so as to make it easier to work on. After a very good clean with soap and water, then Methylated spirits, I sprayed the Skylight a couple of times with Jenolite Stop leak sealer.I have not had any leaks from the skylight at all. The Caravan has been out in the open all over the winter so I feel this has been a great test.I would Definitely recommend JENOLITE for this type of leak.

If you want an easy fix solution to an annoying trickle or even a major crack in UPVC Pipework either indoor or out then look no further than JENOLITE Stop Leak Sealer Spray. Being disabled I have an inset shower tray with a steel grid that will hold a wheelchair.After many years of daily use the sealant around the edges was starting to peel away and an actual crack appeared in the side of the tray.My son originally wasted over £40.00 on some so called acrylic putty.Not only was it useless but there wasn’t enough to do a proper job.Enter JENOLITE Stop Leak Sealant spray. It was a simple job to mask the areas that needed spraying then apply a couple of coats of JENOLITE.Job done!Totally sealed in 10 minutes with 2 coats and because the JENOLITE is practically invisible to the eye my son sprayed all around the tray,even where the tray is sealed to the wall with silicone giving an invisible barrier against leaks that will last for years.A truly excellent product I wouldn’t hesitate to buy again although that could be a while because I still have more than half a canister left,so it’s great value for money as well!A true 5 star product in every way!

I cannot comment on whether this leak sealer works or not because the spray can I received did not have a ball bearing inside to mix the sealer . I shook the can , I tapped the can and shook it for a full 10 minutes and still the ball bearing did not free up ! Yes it was hot weather and I could feel the sealer sloshing about In the can so I can only conclude that there is no ball inside - waste of money .I have used Jenolite spray paints and leak sealer before with great success .

Very good works well

Hatte kleine Undichtigkeiten in meinem Wellplastik Dach. Dafür hat es seinen Zweck erfüllt. Daumen hoch.

Dieses Produkt ist das Geld nicht wert. Sorry. Eigentlich 0 Sterne. Habe bestimmt 10x drübergesprüht (selbstverständlich immer eine Zeitlang gewartet, bis es abgetrocknet war). Aber der Brunnen, in dem kleine Microrisse waren, blieb undicht.

leider hält das Produkt nicht was es verspricht. Mein Leck (Haarriss) wurde auch nach mehrmaliger Anwendung nicht dicht...sehr schade

Hilft überhaupt nicht.Einfach Geldverschwendung :(

Wollte einen Haarriss am ausziehbaren Wasserhahn abdichten.Leider ohne Erfolg.Weitere Reparaturen hatte ich noch nicht.
