An increasing number of homes and light commercial buildings have oriented strand board osb subfloors.
Can hardwood be stapled to osb.
Osb is fine as a subfloor structurally but imo it won t hold a nail or staple as well as spruce plywood.

Staple down engineered hardwood flooring is attached with staples to the subfloor which can be plywood oriented strand board osb high density particle board or even existing wood flooring.
Engineered wood can often be floated meaning the planks connect to each other instead of the subfloor.
Builders choose osb because it typically costs less than plywood free of knots and voids and can be used interchangeably in typical flooring applications where the panels have the correct span rating.

Main concern is nails staples coming loose from the osb over time.
Installing hardwood flooring over osb.
Although adhesive companies state it can work use caution against gluing down any hardwood engineered or solids over particle masonite wafer or osb board.
