Nailing or stapling down wood floors is the most common installation method. The process involves nailing or stapling the wood flooring directly to a wood subfloor. Typically, the flooring is blind nailed through the tongue into the wooden subfloor so that the nails are not visible after the flooring is installed. This installation method works for solid, engineered, some bamboo wood floors, domestic and exotic. Those nails are specifically designed for the application of hardwood flooring.
