Can I use Rust Oleum to repair cracks on a flat roof that has very occasional foot traffic? Does it dry to touch or remain tacky when cured?


Rust-Oleum Fillcoat Fibres Repair Kit is able to waterproof small cracks on flat roofs so may be suitable for you, however if the issue is structural this product will not resolve that.

I have an eight sided gazebo with a pitched T&g wood roof. The timber has developed small cracks. Is there a suitable sealant paint ?


Yes, we would recommend Rust-Oleum Mathys Fillcoat Fibres, bare timber should first be primed with Rust-Oleum Mathys Primer 44 HS. Alternatively you could also consider Bedec Super-Flex.

Can I use Rust-Oleum Waterproof paint on a flat roof that has been fibreglassed. And can you walk on it.

Question: Is rust-oleum roof paint a one coat application? What is the expected life of the paint on a flat felt roof? many thanks

Rust-Oleum Waterproof Roof Paint has been discontinued and replaced by Rust-Oleum Mathys Fillcoat Fibres. For any protective paint specification we would not normally consider just a one coat application, and in an application such as a flat felt roof, a two coat application of Rust-Oleum Mathys Fillcoat / Rust-Oleum Mathys Fillcoat Fibres would be more suitable.

Life expectancy is always difficult to define with a maintenance system, however, we would expect 5+ years depending upon exact exposure conditions.

Is Rust-Oleum Waterproof Roof Paint toxic to fish? I want to use it to recoat the inside of a fibreglass fish pond.


Rust-Oleum Waterproof Roof Paint cannot be used in permanently submerged areas like swimming pools and ponds. Teamac Chlorvar Chlorinated Rubber Paint or Teamac P101 2 Pack High Performance Finish can be used on fibreglass in swimming pools and ponds and will not be harmful to the fish once dry.

Does Rust-Oleum Waterproof Roof Paint work on asbestos?
