Dating corrosion of metal lath
Dating corrosion of metal lath
(OP)
Is anyone aware of published research used to date water damage to metal lath (rust)? I have rusted lath near a plumbing leak. The lath is orange in its discoloration, with rust bleeding onto the remains of the plaster ceiling. I need to determine the age of the corrosion; specifically if the corrosion is 14 days old or less.
I don’t know an exact source that provides a duration, specifically for metal lath. I do know that corrosion of steel is dependent on several factors, such as atmospheric conditions, exposure to moisture, exposure to chemicals, type of steel (mild steel A36, A992 etc..), zinc content, and steel thickness, to name a few that may be most relevant for metal lathe in a stucco.
Thank you for your consideration.

However, the best approach would be an on-site experiment using the identical metal and environment. That would eliminate almost all the variables and control the rest. Should establish at least an approximate corrosion rate with +/- days accuracy.
