questions Pat Rooney on 18/06/2018

Is this product suitable for application to the underside of a corrugated iron shed roof?


Yes, assuming the surface is bare metal, after preparation (see product data sheet) apply Rust-Oleum Mathys Metal Cladding Primer followed by Rust-Oleum 5090 Anti-Condensation Coating.

Please note that Rust-Oleum 5090 Anti-Condensation Coating works in an environment where there is short term high humidity followed by longer periods when humidity can escape e.g. bathrooms. It cannot work where the humidity builds up and cannot then escape. So if this shed was closed and humidity built up a as a result of sunshine, you would still get condensation forming and then dripping down from ceiling.

Question: Hi, is this paint safe to use in a child's bedroom? I am trying to find a paint for a small cold bedroom that is prone to condensation. I am having his walls insulated and then I need to paint the plastered walls. Is this paint appropriate and also what would I need to prime the plastered walls with in a room prone to condensation. many thanks

Rust-Oleum 5090 Anti-Condensation Coating is intended for commercial applications, for domestic projects we would recommend Thermilate InsOpaint Anti-Condensation Paint. Once dry, prime the bare plaster walls with 1 coat of Zinsser Gardz, followed by 2-3 coats as required of Thermilate InsOpaint Anti-Condensation Paint.
