Does solvent act as a minus of fat (or PVC), even though it evaporates? It seems like it does when it is added neat, it thins the paint so it is less fat or concentrated, spreads it farther on the surface. But it only temporarily reduces the PVC because as soon as it has evaporated then the ratio is the same as before, right? And when solvent is part of a medium (solvent and oil) then it seems like only the amount of oil matters since the solvent evaporates, you are just adding up the overall oil content of each layer.
Can anyone clarify this?
Sorry for the duplication, my question wasn’t coming up in the Search All, so I though it didn’t go through and tried again.
You are correct in your assumption. There is, however, a point where you can thin the paint to such an excessive extent that the paint is so dilute that the film is no longer coherent. For the most part what you state is correct.
