I am starting to lay some repair work on my wood floor. The repair is like almost in the middle of the floor .about 7ft by 2 foot. Where would i start at ? The groove or the tongue side? Thank you.

Work back starting at the tongue side. Pull nails as you take each row out.

Ok thanks, now when i start to lay do start at the wll side or the where i there us still the boards that i left. Thank you.

You will need to remove the boards and start where the tongue is exposed. This will make the repair easier. Start removing the leftover boards against the wall by destroying the board closest to the wall if you can not set the top nails through with an eighth inch punch and pull it up. Then pry out the boards carefully as you remove them. Use the boards that you have salvaged to start the repair. As you use all the
salvaged boards you can tell how many new boards you need.

Ok thanks i dont think i can salvage the boards they are warped. Thanks again.
