Polar LeakFix Liquid Rubber - Rubberised Roof Sealant - Clear - 500ml

We have a problem chimney, or a problem wall, or both. It’s the bane of my existence. Some people talk about ghosts haunting them. We don’t have ghosts but our damp wall haunts me. I’m sure there’s multiple issues, but one thing is for certain is that a drip comes down from the top of the chimney stack. I had new pots fitted and new flaunching. And still the bar steward leaked. Cue more scaffolding and I got up and had a look myself. The new flaunching had cracked, I can’t blame the workmen, I guess it’s the nature of the beast. So I bought this stuff. Facebook is full of periodic building buffs who claim I’ll be going to hell for using this product on a historic property, but you know what? It seems to have stopped our chimney leak from the top. I applied it with a brush. It’s quite thick but also runs if you’re not careful. So apply thinly and add additional coats of needed. It dries relatively quickly and gives a silicon seal looking film over the material applied to. Placing a hose on it generated no leaks, have I succeeded in solving one of my issues with my nemesis wall? Will it last? I don’t know. I hope so, as scaffolding is £500 a pop is too expensive to keep messing around with. But initial results are encouraging.

Used this a few weeks ago to repair a small cement crack above my bay window. I have not seen the annoying damp patch inside the bay window since.

Excellent product. Does exactly what it promises to do on the tin.

Wonderful stuff. I’ve used it on patios, shed roofs, gutters, great coverage.

Slightly disappointed with purchase. Was expecting a thick almost silicone like product but this is quite runny. Thought I would use it to seal the roof felt between joins but doesn't really do the trick. Maybe better for different applications.

Great stuff works great

I like this product, but it sometimes requires two coats amd needs to be applied quite thickly.

Perfect

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.

I had a spot on an older roof that needed to be replaced but I was planning on replacing it in a few months when the weather was nicer and i had the time. This stuff did a great job helping reseal the area where water had come through during a heavy storm. It smells like rubber cement and seems to have a slightly runnier consistency. With these shingles being extremely old and dried out, it didn't spread extremely far but filled in every gap quite in the granules nicely. I was able to use a brush to push it around the whole area. It's similar to putting on a thick asphalt sealer on a blacktop driveway but it is clear and made for shingles. Since the shingles were old and a lot of the connective material has disappeared, you could definitely tell a difference as it made these flat instead of the dried out granular top. The whole section where I put it looks much shinier than the old section. It probably brings it back to looking like a new shingled area. It did the job to seal it quite well; it's just definitely noticeable where you put it on an old roof.

This stuff is exactly what I have been looking for. Other products were very thick and after only a year on my roof have started to split. In fact this stuff is so good it has kept the rain away from our home, except for a couple of showers, for about 3 months now! Regrettably, our water bill has gone up keeping the yard alive. :)

Small gaps seal ok but wider openings require several coats. Be sure to let it dry between coats.

I bought this to seal up six leaking seams in rain gutters. My problem was gutters were 24 feet high and I had a 16 foot ladder, so you can do the math. The paint brush I used on a 8 foot pole could not apply this sealant with enough pressure to be effective. You really need to put his on with heavy brush strokes loaded with the sealant and unfortunately I was not in the position on the ladder to do that heavy enough. After sealing up six seams with one coat, it rained 48 hrs later and all seams still leaked. Im not giving up on the product. I'll try to heavy brush it on once I rent a 28 ft ladder. But, to be effective, I believe you have to brush it on from a foot away with heavy pressure strokes and lots of the sealant on the paint brush. Also, its real sticky so wear disposable gloves to make clean up much easier.
