The Floating Method
Dec 17, · When you install hardwood floors, concrete is one of the best bases to work from — there are only a few steps to take. Follow these steps with care to safely complete the installation yourself. Whether you’re planning on renting out your home or looking to increase its value, using concrete as a base is a great idea. I suggest laying out felt paper over the concrete, sealing the joints with an asphalt adhesive and then laying the wood floor over as though you were installing a floating floor. In New England, a 3/4" hardwood floor installed directly over concrete will absorb moisture from the concrete slab, and the boards will swell and cup. Feb 02, · Floating For floated wood subfloors installed on-grade and below-grade, be certain moisture control is taken into account. This may be as simple as a 6 mil polyethylene plastic covering percent of the concrete and brought up all walls, then trimmed after the floor has been installed.
The misconception is that a concrete subfloor must be completely level to install hardwood. Actually, the floor must be flat, which allows for minor variations in the level. Tiny dips or ridges in the concrete won't affect your hardwood floor installation, but large ones can lead to floor squeaks later as the connection between the floor boards is stressed.
Adding a layer of self-leveling compound to your concrete adds an extra day to your flooring job, but it reduces the chances of problems with your flooring later.
Lay a 8- to foot piece of lumber on the concrete floor. Position yourself in a way that allows you to see the board more or less from the side and look for low areas that show up in relation to the flat lumber. Measure the depth of the lowest area of the dips. Mark the low areas with a piece of chalk, noting where the top edges of the dip meets the lumber and becomes flat with the floor.
Mix self-leveling compound with water in a bucket. Pour it on the low spots. The compound is designed to fill dips in concrete as it dries. Add enough of the compound slurry to fill the low areas up to the chalk marks you made on the flat floor. Wait for the compound to dry. It typically dries quickly, but it's best to wait overnight before you begin adding your flooring.
Scoop some flooring adhesive with a trowel and spread it along a portion of the wall where you plan to lay your first row of hardwood, covering a small area at a time to keep the adhesive from drying before you lay the wood.
Slide a notched trowel over the top of the adhesive. Lay your first board in the corner on the adhesive. The tongue of the board should face the wall. Continue laying boards along the first row with spacers between the boards and the wall, spreading more adhesive as necessary. Cut a hardwood board in half so it's shorter than the rest of the boards.
Use this to start your second row at the same end where you started the first row. Cutting the board helps you alternate the seams so they don't line up along the floor.
Spread some adhesive, then slide the tongue of the cut board firmly into the groove of the first board in the first row. Press the board down into the adhesive.
Continue laying the row, cutting the last board to fit. Place painter's tape across the seam to help hold the boards in place until the glue dries. Continue laying the boards across the floor until you have about two or three rows left. It's impossible to lay these last rows without standing on the row you just glued down, so stop the installation until the glue dries for 24 hours and you can stand on it without shifting the wood. Spread adhesive for the last few rows and install the hardwood by pushing the tongues of the new boards into the grooves of the last secured row.
Rip-cut the last row by cutting it lengthwise if necessary to fit the remaining space between the wall and the flooring.
