Hi, I am new to this forum. I have many years experience with paints and finishes.
I have encountered a problem with shellac blistering when exposed to direct sunlight on a hot day. I have done some test pieces on kild dried redwood to rule out moisture in the wood. I make art furniture (small tables with paited designs) and have only recently started using shellac due to allergies to other finishes. It works well for me except for this problem. The shellac had been dry over a week and had several coats. Does anyone know what could cause this?
