Tools and Materials You'll Need

Removing glued-down hardwood floors isn't just about brute force. Having the right tools and materials will not only make the job easier but also help protect you and prevent damage to your subfloor. Here's what you'll need to gather before you start:

Protective Gear:

  • Safety glasses (essential for protecting your eyes from flying debris)
  • Work gloves (protect your hands from splinters and adhesive chemicals)
  • Dust mask (reduce inhalation of wood particles and adhesive fumes)
  • Knee pads (save your knees from prolonged kneeling on the hard floor)

Prying Tools:

  • Pry bar (your primary tool for lifting the boards)
  • Flathead screwdriver (helpful for tight spaces and initial wedging)
  • Hammer (used in conjunction with pry bar and screwdriver)
  • Chisel (for chipping out stubborn adhesive)

Cutting Tools:

  • Circular saw (optional, but extremely useful for large areas or unyielding boards. Set the blade depth to just below the thickness of the hardwood)

Adhesive Remover:

  • Choose a product specifically formulated for removing flooring adhesive. Consult product directions for application and safety information.

Cleaning Supplies:

  • Broom and dustpan (for clearing debris)
  • Rags (for applying adhesive remover and cleanup)
  • Solvent (check compatibility with your subfloor for removing sticky residue)

Always refer to product manuals and safety instructions for any tools or chemicals you'll be using.

Step-by-Step Guide to Removing Glued-Down Hardwood Floors

Now that you're equipped, it's time to get to work! Follow this step-by-step approach for the best results:

1. Preparation:

  • Clear the room of all furniture and any obstacles.
  • If you want to protect baseboards, consider covering them with painter's tape or carefully scoring along the edge where they meet the hardwood.

2. Test the Adhesive:

  • In an inconspicuous corner, try prying up a board. This will give you a sense of how firmly the adhesive is holding and help determine the best strategy.

3. Start with a Pry Bar:

  • Find a seam or slight gap at the edge of the floor.
  • Insert your pry bar, angling gently, and begin lifting. Use a hammer to tap the pry bar if needed.
  • Work your way along the board, carefully prying it up as you go.

4. Circular Saw (If Needed):

  • For very stubborn areas or large rooms, a circular saw can save time and effort.
  • Caution: Set the saw blade depth to slightly less than the thickness of your hardwood to avoid cutting the subfloor.
  • Make cuts across the room, breaking the floor into smaller, more manageable sections.

5. Adhesive Remover:

  • Once the bulk of the boards is up, you'll likely have adhesive residue.
  • Follow the instructions on your chosen adhesive remover for application and dwell time.
  • Use a scraper or chisel to work off the softened adhesive.

6. Clean-up:

  • Sweep the floor thoroughly to remove debris.
  • If there's lingering sticky residue, use a solvent compatible with your subfloor material to wipe it clean.

Additional Tips

  • Work in small sections: Don't try to tackle the entire floor at once. Focus on manageable areas to avoid getting overwhelmed and prevent adhesive from drying again.
  • Patience is key: Glued-down floors won't come up in a flash. Take breaks when needed, and be prepared for it to be a multi-hour or even multi-day project.
  • Wood type matters: Harder woods may withstand more forceful prying, while softer woods might splinter easily. Adjust your technique accordingly.
  • Seek help if needed: If the project is too large, the adhesive is exceptionally stubborn, or you're unsure, consider hiring a flooring professional with the right tools and experience.
  • Preserve the wood (optional): If you want to salvage the hardwood for reuse, be extra careful during the prying process to minimize damage.

Dealing with Subfloor Issues

Unfortunately, removing glued-down hardwood floors can sometimes reveal damage to the subfloor underneath. Before installing any new flooring, it's crucial to address these issues to ensure a smooth and long-lasting result.

  • Minor gouges and scratches: These can often be filled with wood filler or a patching compound suitable for your subfloor material. Let it dry completely and sand smooth.
  • Deep gouges or holes: More significant damage might require cutting out the affected section of the subfloor and replacing it with a new piece.
  • Uneven subfloor: Removing the hardwood might expose an uneven subfloor. Depending on the type of new flooring you're installing, you might need to apply a self-leveling compound to provide a flat, stable base.

If you encounter substantial subfloor damage or are unsure how to proceed, consult a flooring contractor for assessment and repair advice.
