Howdy,
Rain season has started and we got something like solvent pop on a bike that we painted with Delfleet.
Painted a pickup with PPG DG and got something that looks like craters. We made a test with the DG yesterday
and it seems OK when we use the extra slow thinner. Is there any special to consider when painting at over
90F and humidity over 80? Should I keep the fans running when the paint drys?Dag
I would keep the fans running for awhile.
Another thing to consider is any urethane that gets hardened will cure faster when it’s humid so the next slowest reducer will help. Iso’s react with 2 thing, moisture and resins. When there is more moisture in the air they will dry faster.
btw, basecoat is the opposite. It takes longer for the solvents to escape when it is humid due to the air being heavier.
