I have a very low pitched steel clad roof which is suffering water ingress only in certain wind blown conditions. Do you have a brush applied product which will seal these sheet joints (sheets in good condition) with high thermal expansion movement rates? I would prefer something which remains flexible with a fleece reinforcer such as 'Turbo Poly Seal'?
Assuming you are looking to seal the joints in the steel sheets, they are clean dry, sound and prepared as detailed in the Technical Data Sheet we can recommend Rust-Oleum Mathys Elastofill.
