Step by Step Hardwood floor guide with photos.
 

Preparation
[1] Cover the subfloor with closed-cell foam underlayment. Roll out the foam perpendicular to the direction of the flooring. [2] Butt together the seams of the underlayment; don’t overlap them. Secure the seams with 2-in.-wide duct tape or masking tape. [3] Use a piece of flooring and foam underlayment as a cutting guide for trimming the door casings and jambs.

 

Installation
[4] Set the first plank against the wall with its tongue edge facing out. Place 1/2-in. spacer blocks between the plank and wall. [5] Use a hammer and short tapping block to connect the end joints between the floating-floor planks in the first row. [6] When cutting with a jigsaw, hold the plank upside down to avoid splintering the top. With a handsaw, hold it good side up. [7] Use a hammer and long tapping block to close the tongue-and-groove joint. Tap sharply, but don’t pound on the block. [8] When notching a flooring plank to fit around a wall corner, be sure to leave a 1/2-in. space between the notch and the wall. [9] Install the last two rows of flooring using a steel pull bar. Hook the lip of the bar onto the plank, then tap on its anvil.

 

Finishing
	[10] Conceal the expansion space with baseboard molding. Important: Nail the molding to the wall studs, not to the flooring. [11] Complete the job by nailing quarter-round shoe molding to the baseboard. Tip: Paint or stain the molding before installing it.
