Pine Flooring Over Concrete Slabs

Pine flooring can be successfully installed over concrete slabs. This adaptable flooring option not only adds a touch of natural beauty to your space but also offers durability and ease of installation, making it a popular choice for transforming concrete surfaces with a warm and inviting aesthetic

The significance of a meticulously executed installation process cannot be overstated. Beyond the functional aspect, a well-installed pine floor contributes significantly to the visual appeal of a space. It not only elevates the aesthetic quality but also ensures durability, making it a worthwhile investment for homeowners seeking a lasting and beautiful flooring solution.

Types of Pine Flooring

Pine flooring comes in various types such as wide plank, heart pine, Southern Yellow Pine, reclaimed, Eastern White Pine, knotty pine, prefinished, and unfinished.

Each type offers distinct characteristics, ranging from rustic charm to durability and customization options. Factors like grain patterns, knot presence, and color variations influence the aesthetic appeal of pine flooring, making it essential to consider the desired look and maintenance requirements when selecting the right type for a space.

Typical widths for pine flooring planks range from around 3 inches to 12 inches, with the most common widths falling between 5 inches and 7 inches. Lengths can vary as well, often ranging from 6 feet to 12 feet or more. These dimensions can create a variety of looks, from a more traditional appearance with narrower planks to a more contemporary aesthetic with wider planks.


  1. Moisture Meter: To test the moisture content of the concrete slab and ensure it’s suitable for installing wood flooring.
  2. Circular Saw or Miter Saw: For cutting the pine flooring planks to size, especially for fitting around doorways, corners, or obstacles.
  3. Pneumatic Flooring Nailer: Used to securely attach the pine flooring to the plywood subfloor. Alternatively, you can use a drill and screws for installation.
  4. Tape Measure and Carpenter’s Square: For measuring and marking the layout of the flooring, ensuring accurate cuts and alignment.
  5. Level: To check the levelness of the concrete slab and plywood subfloor, ensuring a flat and even installation surface.
  6. Adhesive: If not using nails or screws, adhesive is needed to secure the plywood subfloor to the concrete slab and to attach the pine flooring to the subfloor.
  7. Concrete Patching Compound: For repairing any cracks or uneven areas in the concrete slab before installation.
  8. Safety Gear: Including safety glasses, ear protection, and dust masks to protect against sawdust and debris during cutting and installation.
  9. Hammer and Pry Bar: For removing any existing baseboards or trim, as well as for tapping flooring planks into place during installation.
  10. Flooring Spacers: To maintain a consistent expansion gap around the perimeter of the room while installing the flooring.
  11. Sanding Equipment: Including a floor sander or orbital sander and sandpaper for smoothing out any rough edges or imperfections in the wood before applying finish.
  12. Finish Applicator: Such as a brush, roller, or lambswool applicator, for applying a protective finish, such as polyurethane or wax, to the wood flooring.

B. Step-by-Step Installation Process

  1. Prepare the Concrete Slab: Ensure that the concrete slab is clean, dry, level, and free from any moisture issues. Repair any cracks or uneven areas in the slab using concrete patching compound.
  2. Install a Moisture Barrier: Lay down a moisture barrier or vapor barrier over the concrete slab to prevent moisture from seeping into the wood. This can be a sheet of plastic or a specialized moisture-resistant underlayment.
  3. Install a Plywood Subfloor: If desired, install a plywood subfloor over the moisture barrier. Use pressure-treated plywood to prevent moisture damage. Secure the plywood to the concrete slab using adhesive or concrete screws.
  4. Acclimate the Pine Flooring: Allow the pine flooring to acclimate to the room’s temperature and humidity levels for at least 48 hours before installation. Stack the flooring planks in the room where they will be installed, leaving space between each plank for air circulation.
  5. Plan the Layout: Plan the layout of the flooring, considering factors like the direction of the floor joists, the location of doorways, and the orientation of the room. Start the installation from the longest wall, working towards the opposite wall.
  6. Install the First Row: Begin by installing the first row of pine flooring along one wall. Leave a 1/2-inch expansion gap between the flooring and the wall to accommodate for expansion. Use adhesive or nails to secure the flooring to the plywood subfloor.
  7. Continue Installation: Continue installing the pine flooring row by row, working across the room. Use a pneumatic flooring nailer or drill and screws to attach the flooring to the plywood subfloor. Stagger the end joints of the flooring planks for a more stable and visually appealing installation.
  8. Cut Planks as Needed: Use a circular saw or miter saw to cut the pine flooring planks to size as needed, especially for fitting around doorways, corners, or obstacles.
  9. Finish the Floor: Once all the flooring is installed, install any necessary trim or molding around the edges of the room to cover the expansion gap. Sand the floor to smooth out any rough edges or imperfections, and apply a finish, such as polyurethane or wax, to protect the wood and enhance its appearance.
  10. Allow for Cure Time: Allow the finish to dry and cure according to the manufacturer’s instructions before moving furniture back into the room and allowing foot traffic on the floor.
  11. Following these steps will help you successfully install pine flooring over a concrete slab, creating a beautiful and durable finished floor.
