Bowed boards or boards over low spots should be weighted down while the adhesive cures. For example, we require that installers roll and cross the floor with a lb. Also, traffic in the area must be restricted for hours. Heavy traffic should not resume until 24 hours after the engineered hardwood flooring installation is complete. Note: When installing engineered hardwood floors over radiant heated subfloors, turn the heat off for 24 hours before, during and after installation.

You do this in three to four areas around the slab. Leave it for 24 to 48 hours. If you see signs of moisture or condensation on any of the plastic, you likely have a problem, but you can never be sure how big, or what it is, or exactly how much moisture there is.
The calcium chloride test measures the surface moisture of the slab. You can see the kit and how it works in this video. Humidity sensors or moisture meters require drilling holes and inserting probes to measure the amount of water. Some meters measure results in pounds of water per 1, square feet of the floor during a hour period. Other meters can measure relative humidity in the slab. One very accurate testing method is to use the Wagner Rapid R.
Most flooring manufacturers say you should not install hardwood over concrete if the tests show the moisture emission rate is over 3 pounds. When installing hardwood flooring on basement , the concrete must be flat so the tongue and grooves of the hardwood meet and connect. Old basement slabs can crack and buckle in places. You need to fill any large cracks and be sure that the entire floor is level. That means pouring a thin layer of cement to fill in dips and gaps.
Here is a short video to show you how to level a concrete floor. To check the evenness of the slab, use a 6-foot or longer straight edge. You may have to cut one utilizing a table saw to ensure straightness.
Lay the straight board on the floor and place a level on top. Concrete is very porous like a sponge. Water can quickly pass through it causing moisture problems, especially below grade.
Typically, it is sheets of plastic laid on the slab and taped at the seams with waterproof tape. Watch this video to see how easy it is:. He adds an optional underlayment on top of the moisture barrier for sound reduction. There are other moisture barrier options. Ask your flooring professional what he or she uses.
A subfloor is the floor surface directly under the hardwood floor. In this case, the subfloor is the concrete slab. Wood needs to move as the humidity increases and decreases throughout the year.
For these reasons, you should avoid gluing, nailing or permanently attaching directly to the slab. It adds a lot of extra time and effort. It lays directly on top of the waterproof barrier, or combination of barrier and underlayment, to help cushion and insulate. Be aware of the additional height that the subfloor and underlayment add.
They can add up to two inches in a basement that may already have a low ceiling. There are many options for building a plywood or OSB subfloor. This video demonstrates a cost-effective method for DIYers. A subfloor allows you to nail or screw into the wood instead of concrete. Instead, a local handyperson or even a DIYer can install hardwood floors and plastic clips themselves see our installation guide.
Then, we recommend covering unsealed concrete with 6-mil polyethylene fabric to block moisture from wicking up the concrete to the hardwood floor. Once your subflooring is level and sealed, you can assemble your Steller Floor right then and there to add instant warmth and character to your space. Even contractors enjoy their flooring installations. Traditional hardwood floors are extremely difficult to refinish or repair and to manage during a remodel.
Luckily, Steller Floors are easily repaired because you can use a suction cup to remove a single plank out of the middle of the floor. Just imagine the possibilities if you want to refinish your floor or remodel—it is a snap to keep your unique and beautiful floor in great condition. Plus, if you ever have a flooding event, moving and removing our flooring is a great way to reduce the chance of catastrophic losses! Learn more here. Instead, you can assemble your Steller Solid hardwood floor right over the sealed concrete subflooring!
At the same time, the engineered hardwood planks must be allowed to acclimate to the environment for two or three days. Using a notched trowel, the installer will spread the adhesive in an even layer over a small portion of the floor, starting on a long wall.
The planks will be prepared by applying wood glue to both the tongue and groove side of each plank. Pieces should fit together perfectly with no gaps, bumps or raised areas from one section to another. Adhesive will be quickly applied and planks laid until the floor is covered. Pressure will be applied, moving across each plank to ensure that the glue is properly adhering to the concrete.
