1. Do you seal even with oil based varnish, and not using water-base.
2. I will insist on 4 coats.
3. The vinyl in other parts of room (dining room, and kitchen) and the living room are open spacing living and flow from one room to the other, however, there is no way I can remove the vinyl from kitchen and dining rooms. If I remove the felt padding from the living room, exposing the subflooring, the living room will be a little less then 1/4" lower then the other rooms (no vinyl). Do I need to lay vinyl floors in the living room to compensate for the difference between the rooms, or it really doesn't make a difference. (we're laying our own floors). Thanks again.
