Hello ya'll....I just finished stripping, sanding, and staining our 100 year old pine floors. I'm debating which topcoat/sealant to use. I was set on a water based poly but want to hear some opinions. With a preggo lady in the house and a 2 year old, was hoping to go with water based for the low fumes. What are the main downfalls? This is going to be a low traffic room. Also, do you guys suggest using a sealant before using the poly? If so-what is recommended? We've put so much time into these floors, I want them to be done well.
