Is this product suitable to seal asbestos/cement guttering? The joints are leaking. Attempts have been made to seal the joints with bitumen previously. Does the bitumen need cleaning off first? 18m long x 300mm wide
Answer from Rawlins’ Technical Team:
Assuming the bitumen products are removed prior to application, the asbestos guttering is bare, clean, dry, sound and prepared as detailed in the technical data sheet you could consider Rust-Oleum Mathys Fillcoat.
I see previous comment about a fish pond, but I have a PVC pond shell which I want to extend up a little and wanted to use this to bridge between the PVC shell and a coated aluminium trim set into a brickwork perimeter above. Would this be suitable or is there another product to recommend?
Answer from Rawlins’ Technical Team:
Unfortunately we do not have a product we can recommend for this application.

Question:
Can I use this for my fish pond. Thanks
Answer from Rawlins’ Technical Team:
No, this product is not suitable for application to a pond.
Assuming the pond is concrete, clean, sound and prepared as detailed in the technical data sheet we can recommend Teamac Chlorvar Chlorinated Rubber.
The pond should not be refilled until completely dry, approximately 14 days.

Question:
I have replaced my wooden gutters with similar size plastic gutters some years ago. The joints on these gutters have started to leak and try as I might I can’t seem to stop the leaks. Would this product be suitable to stop them leaking. Thank you.
Answer from Rawlins’ Technical Team:
Assuming the gutters are PVC, clean, dry, sound and no cracks are larger than 2mm we can recommend Rust-Oleum Mathys Fillcoat Fibres for this application.

Question:
How long does this product last once applied on a GRP flat roof?
Answer from Rawlins’ Technical Team:
We would suggest 5 to 10 years, but this is heavily dependant upon a high level of surface preparation and correct application as detailed in the Technical Data Sheet.
This can be found in the attachment tab on the product page.

Question:
Hi, could I use this to paint over and seal some small cracks in cement on the top of a chimney stack? thanks
Answer from Rawlins’ Technical Team:
Bare concrete/cement would need priming first with Rust-Oleum Mathys Primer 44 HS prior to application of Rust-Oleum Mathys Fillcoat Fibres. If you only have a few cracks to treat then Rust-Oleum Mathys Elastofill may be suitable instead.

Question:
Is Fillcoat Fibres waterproofer suitable for galvanised steel guttering
Answer from Rawlins’ Technical Team:
Yes – so long as the galvanised steel is in good condition structurally, has no rust, has been thoroughly degreased and will be dry and clean at point of paint application. We would also suggest using Rust-Oleum Mathys Fillcoat first as a kind of primer coat to aid adhesion.

Question:
For inside of iron gutter at what rate per m2 should it be applied 1L or 1.5L /m2? or other? PS referring to Rust-oleum mathys fillcoat.
Answer from Rawlins’ Technical Team:
For waterproofing a gutter we would recommend the application of Rust-Oleum Mathys Fillcoat Fibres over any joints and cracks before applying a coat of Rust-Oleum Mathys Fillcoat over the whole gutter area. To provide a more durable, long lasting finish we'd recommend Rust-Oleum Mathys Fillcoat be applied at 1m²/litre.
