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

After 4 years of a dripping condensing pipe on my boiler, I sprayed 3 coats of this stuff... And not only did it improve the appearance (as there were several attempts in the past) but stopped the leak. My only last option was to replace the pipe, but that was a horrendous job.. so for me, excellent!

I used this to repair a leaky union in my guttering. One coat and I'm no longer suffering that infernal dripping. Brilliant paint and easy to use.

this product took care of every leak i had on my metal roof. highly recommend this product. when i applied it i put it on with a paint brush using strokes across ways and then up and down strokes. it works great

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.

My roof has a small leak i can't see but the plywood sagged so this sealed the area above the sagging plywood until it Is time to reshingle it.
