Lots of great reading on this site.
Almost ready to put down my unfinished flooring. Flooring is a mix of maple, birch, beech. Some curly, some birds eye, some spalt.
Took up carpet and added a pile of screws to the 3/4" ply.
Flooring was bought as kiln dried rough lumber and run on a friends 4 sided planer.
Questions: 1) do I want to use a layer of tar-paper or is there a better underlayment? Basement below is very dry.
2) There are some pieces that are highly figured and have a few inclusions, is there a finish that will fill such areas?
3) Flooring is a mix of 5"-7", rather than glue I want to face screw and plug prior to finishing. Using maple plugs so hardness will be the same. I had thought the screws would need to line up on joist, but in practice I'm thinking you would want screws near each joint? So which is it and with 2x10 joist 3/4" ply and 3/4" flooring what screws would you use?
Thanks in advance.
