I had a pine entertainment center built in my living room. It will not be subjected to much wear and tear. I purchased Olympic Maximum solid stain to finish it. I have used solid stain in the past and found it easy to work with. My question is after much searching online and not finding my specific question is; Once it is applied and dried will it be safe to use the outdoor stain indoors. Would it be better to seal it with an indoor grade sealer?
