Nail-In Installation Process
In order to achieve a “blind nail” job, simply make a chalk line over the subfloor in the direction of the boards, marking the first row. The flooring boards will them be arranged along the line and the last one should be cut to the appropriate length with a chop saw. In the event the boards have tongues, they need to be placed facing in the direction in which you are incorporating to install the flooring.
Using a combination square and pencil, lightly draw lines perpendicularly across the boards. Space them consistently, 7 to 10 inches apart from one another, spacing closer if wide boards are being used. Now, draw lines within one inch of the boards’ ends.
Next, drill two neat 1/8-inch holes on each line. Position the holes ¾ inches from the boards’ edges and if the boards are wider than 6 inches, an extra hold should be added between them for security. Then, in each hole, drive a 1 ½ inch finish-style nail and use a nail set to ensure that the head of the nail is sunken and not visible.
