So, my boss finally got us automated not long ago, we have a small buisness that makes bleacher boards for school gyms, we use the same waterborne poly that is on the gym floor & one of the machines that he got was a older Falconi spray pod & conveyor line, pic below.
Up till now we have been using an airless system to hand spray the boards, supper flat & very good finish, but this thing uses air & now we are getting tiny miro bubbles in the finish, I have searched online for a solution, we even have our poly supplier looking into changing our mixture, they have now introduced alcohol to it, but still getting the bubbles, I've tried turning down the air pressure, but that just leaves me with to thin of a layer, we have to get a decent build on these, any help would be appreciated, thanks.
