hello, my partners house has fin-lock gutter which has some leaks, will your product solve this issue ?


Assuming the gutters are concrete we would instead recommend using Rust-Oleum Mathys Fillcoat Fibres.

Question: my shed roof is profiled metal with some sort of plastic coating which is starting to wear so the metal underneath is showing signs of rust. Can this product be used on my roof, if not is there another product which would do the job?

Assuming the roof is pitched, we would recommend Rust-Oleum Mathys Noxyde instead of the 802 HB Waterproof Roof Coating.
