While finishing my latest quarantine project, my mind began to wander. I was using an oil finish and while waiting for it to soak in I asked myself what would happen if I heated the wood before putting on the finish? I’m thinking hair dryer or heat gun not hot enough to ignite the wood or finish.
I came up with three possible answers.
#1 Nothing changes. No impact; visible or otherwise.
#2 The oil soaks in deeper because the wood pores are opened up by the heat. The result is a finish that looks the same but is deeper and offers more protection.
#3 The warm wood absorbs more oil but as the wood cools the oil is squeezed out of the pores creating a hot mess (pun intended).
Anybody have any thoughts? Experience?
