Flooring should sit in the room for at least 48 hours prior to installation, giving it time to expand or contract in relation to the room's temperature and humidity. This prevents buckling and other problems after installation.
Use the pry bar to remove baseboard from the wall and set the pieces aside for reinstallation. Floating laminate planks (the kind used in this project) should be installed over a hard, smooth surface, such as vinyl. Remove damaged flooring to reveal the subfloor.
Clear the floor of staples, nails, and other debris. Roll out the underlayment. Do not overlap adjoining strips. Use the utility knife to cut pieces as needed. The foam underlayment deadens sound and helps the floor feel more resilient.
Depending on your layout, you may need to rip, or cut, the first row of planks lengthwise. If using a power saw, cut with the finished side down; if using a handsaw, cut with the finished side up. Use clamps to steady planks as you cut them.
Wedge the spacer chips that come with your installation kit between the wall and the planks to leave an expansion gap of 1/4 inch.
Install the planks with the tongue side facing the wall (some manufacturers recommend you cut off the tongue edge of planks that face walls). Connect one plank to another by connecting the tongues and grooves. You may be able to snugly connect the planks by hand, or you may need to use a pull bar from the installation kit and a hammer to pull them together, or a tapping block to tap the joints together.
Cut the last plank in the row to length and install. Be sure to save the scrap if it's at least 12 inches long.
As you snap on new rows, stagger the seams at least 12 inches in adjoining rows. You often can start a new row with the scrap from the plank you cut to end the previous row.
You'll need to slide the planks into position at an angle, then gently pry them into place with the pry bar. Be sure you leave a 1/4-inch expansion gap between the last row and the wall.
Don't try to cut planks to fit around door casings. Instead, use the jamb saw to cut the door casing about 1/16 inch above the height of the flooring, giving the plank room to slide under the casing. Rest a piece of flooring with underlayment on the floor and against the casing. Rest the jamb saw on top and cut the casing to the desired height.
After the planks are in place, reinstall the baseboard molding using the hammer and finishing nails. Then install shoe molding over the expansion joints and use transition strips to connect the laminate to adjoining surfaces, such as tile or carpet. Do not nail through the floor, just through the trim and wall. Your laminate floor installation is now complete, and you are able to resume use of your room immediately.
