I am building a new house. I want my floors to be as natural as possible (they are 2" white oak" and I want to avoid the "ambering" I keep hearing about. My builder's floor guy has recommended Bona Traffic Naturale or Bona Traffic HD. My question is should he be using a sealer first? Have read out here that a sealer must be used to avoid the tannin pull. Floor guy has said that normally he would be doing a stain that would act as the sealer...but absent a stain, shouldn't he be using a sealer first for both products? I am not confident about the data I am getting via my builder from this floor guy, I feel the need to trust but verify so thanks for any assistance!
