NAILING SCHEDULE
NOFMA Certified Hardwood Flooring Must be installed over a proper subfloor.*
Tongue & Groove Flooring is blind nailed on the Tongue Edge with face nailing required on starting runs (1-2) and finishing runs (2-4).
Square Edge Flooring is face nailed.
Inadequate nailing contributes to cracks and noisy floors by allowing movement of the flooring.
* (Use 1 1/2" fasteners with 3/4" plywood subfloor on a concrete slab. A concrete slab with screeds 12" o.c. does not always require a subfloor.)
