One of the most popular choices for DIYers, installing T & G floors, it only requires nails for the first row of boards. Here's how to install a T & G bamboo flooring:

• Use 1/2-inch spacers to assist in maintaining the expansion gap between the first row of flooring planks and the wall. 

• Put the first board up against the mason's line with the groove side facing away from the walls. 

• Put one 1/2-inch spacer against each wall and slide the end of the board up against those spacers. 

• Drill pilot holes that are spaced according to the manufacturer’s instructions. A safe bet is spacing them every 4- to 6-inches and 1/2- to 1-inch away from the edge against the wall. 

• Drive flooring nails through the pilot holes. Countersink all nails.

• Place the upper drop-lock end of the second plank on the lower drop-lock end of the first plank. The ends do not click-lock. Maintain a straight edge along the row. 

• Cut the last board of the row to fit using a table saw, leaving a 3/4-inch expansion gap. 

• Now, it's time to install the second and remaining rows. 

• Cut off a section of the first plank lengthwise to ensure joints are staggered 6 inches apart. 

• Hold the plank with the tongue facing the previous row. Keep it at about 30-degree angle. 

• Insert the tongue into the groove. 

• Make sure the tongue is snugly and securely engaged in the groove by exerting a constant pressure in the direction of the groove. 

• Maintain the pressure while pressing the plank flat to lock the edge joints. 

• If there is a slight gap along the edge joints, it can be eliminated with the help of a tapping block and plastic mallet. Use caution to prevent impact damage. 

• Cut the last row to width, leaving a 3/4-inch expansion gap. 

• Install the baseboard and shoe moulding to cover the expansion gap.  

• Install threshold or transition strips in place where the edge of the floor is exposed.
