I have 3 general questions regarding hardwood floors.
1. Contractors insist that you put down a sealer prior to the varnish. Is this true for very hardwoods? (not oak or pine)
2. I would like 4 coats of varnish. Contractors do not recommend this. They usually put 2 and sometimes 3. Why not 4 -besides time and cost?
3. We pulled up the carpet and there is felt padding under the carpet. Can we lay hardwood floors on top of this? We have vinyl in other parts of the room, and we're trying to level everything. The felt padding is about 1/8" higher then the vinyl floor. Is this okay. or Is it better just to remove the felt padding. I have 3/4" plywood under this. Thanks so much.
