- 1). Lay flooring adhesive along the starting edge of the floor, generally, the longest edge that doesn't contain the doorway, using a notched flooring trowel. Spread the adhesive over about a two-foot-wide line along the wall, from end to end.
- 2). Lay the starting course of engineered floorboards next to the wall, positioning the boards so the grooved sides are facing the wall. Set spacers between the floorboards and the wall to create a small gap there that will allow for natural expansion of the wood. Link the boards together end to end by their tongue-and-groove edges. Use a miter saw to cut the last board in the course so it fits against the side wall.
- 3). Lay the second row of boards next to the first, connecting the tongue-and-groove edging along the sides. Get the boards snug to each other by placing a piece of scrap flooring against each new outer board and tapping it with a hammer.
- 4). Continue across the floor course by course, positioning the boards so the ends don't line up between courses. Keep going until you are approaching the ending wall and running out of room to work. Allow the adhesive to set for 12 hours.
- 5). Return and install the final portion of the flooring. You should be able to stand on the previously laid flooring now. Use a table saw to length-cut the boards of the final course so they leave a 3/8 inch gap at the wall. Floor trim will cover the gaps.
