Installation Method

There are primarily two methods for installing engineered hardwood flooring on concrete: floating and glue-down.

Floating Method:
In this method, the flooring planks are not attached to the subfloor. Instead, they “float” above it. The key steps include:

  • Lay the underlayment across the concrete floor, ensuring seams are staggered.
  • Start in a corner and lay the first row of planks, ensuring the tongue side faces the wall.
  • Use spacers to maintain an expansion gap of about 1/4 inch between the planks and the wall.
  • Continue laying planks row by row, clicking them together until the floor is complete.

Glue-Down Method:
This method involves applying adhesive directly to the concrete before laying the planks. Steps include:

  • Apply a suitable flooring adhesive using a notched trowel to the concrete.
  • Lay the planks in place, applying firm pressure to ensure good contact with the adhesive.
  • Follow the manufacturer’s instructions regarding the drying time before walking on the floor.

Finishing Touches

Once the flooring is installed, it’s time to focus on the finishing details:

  • Install baseboards or trim: Cover the expansion gap with baseboards or quarter rounds, ensuring they do not compress the flooring.
  • Clean the surface: Remove any adhesive residue or dust from the new flooring.
  • Allow acclimatization: Let the flooring settle for at least 48 hours before heavy use to adjust to the room’s temperature and humidity.

Maintenance Tips

To prolong the life of your engineered hardwood flooring, adhere to the following maintenance practices:

  • Regular cleaning: Sweep or vacuum regularly to remove dirt and debris. Use a damp mop with a suitable hardwood floor cleaner.
  • Avoid excessive water: Do not soak the floor; excess water can damage the wood.
  • Control humidity: Maintain indoor humidity levels between 30% and 50% to prevent expansion or contraction of the wood.

By following these guidelines, the installation of engineered hardwood flooring on concrete can be executed smoothly and efficiently, resulting in a durable and aesthetically pleasing floor.
