metalwork
Is it possible to learn whether metalwork was primed properly? We’ve had a number of contractors tell us the considerable amount of rust on our building’s metal terraces and stairs (5 year old building) is due to lack of proper priming before painting. Is there a way to actually prove or disprove this? thanks all

I think you’ll end up going through a lot of effort for minimal return. As Steve points out, could be a poor prep job, could be site conditions (stuff near salt water is going to rust much quicker, southern facing paint jobs tend to not last as long, etc.) or could be wear patterns. When you say stairs and terraces, it’s going to be a rare paint that can stand up to five years of foot traffic. If you’re really serious about this, then look and see where the rust is happening. If it’s on areas that shouldn’t have any wear taking place and it’s rusting, then there was probably a problem with application, but it could be priming, it could be improper cleaning before priming, or could be the paint. Bottom line is if it was sloppy/improper application, that should have been caught at the time by your site super. It’s going to be very difficult to recoup anything five years after the fact.

probably bad techniques used, wrong primer, wrong application, etc…good job should last 15 years

it may not have been a matter of properly primed but more a matter of quality of product and if that is the case, what recourse to you have unless they promised to use a certain product (if this was done by a developer, cheaper would have been the answer). There are many factors that can mean properly primed and sometimes I think many people would consider those factors extreme – however, if I were doing work on my house, I would want the steel cleaned and then acid washed. Now who does that on a jobsite? maybe cleaned and primed with a rusty metal primer ever if it is not rusty? I am not sure there is a way to prove this at this point except to say to see if it were primed at all. Site conditions/high humidty could have been a reason for failure ever it they did everything correctly. Steve
