Rough-sand the Floor — Rough Sanding (Drum Sander)
Part of project
Hardwood Floor Refinishing · Step 3 of 12
In this video
Choose the appropriate sander based on the condition of your floor. If the floor is badly worn, start with a drum sander (like the American Sanders EZ-8 shown in the video). Use a coarse sandpaper grit, such as 36 or 40. Practice on a sheet of plywood first to get accustomed to the machine. Move the drum sander with the grain of the floorboards, covering three to four-foot strokes at a time. Overlap each stroke by at least one-third of the belt width. After the initial coarse sanding, switch to a finer grit, like 60, and repeat the process.
FAQs
Is hardwood floor refinishing truly a 'beginner' project, and what contributes to the 7-day estimate?
While categorized as beginner, this project requires careful attention, physical effort, and proficiency with powerful rental tools like drum sanders. The 7-day estimate accounts for multiple sanding stages, thorough dust removal, and crucial drying/curing times between finish coats, which cannot be rushed. Plan for a full week where the area is largely unusable.
What are the essential tools I absolutely need, and what are the main safety concerns when using them?
You'll definitely need to rent a drum sander, an edge sander, and ideally a buffer or orbital sander for intermediate and fine grit steps. Safety concerns include significant dust inhalation (wear a respirator!), extreme noise (hearing protection is crucial), and potential for injury from powerful, fast-moving sanding machines. Always follow manufacturer instructions and keep the machines moving to prevent gouging.
What's the biggest mistake beginners make during the sanding process, and how can I avoid it?
The most common mistake is stopping the drum sander while it's running and in contact with the floor, which creates deep divots or 'chatter marks.' To avoid this, always keep the drum sander moving forward or backward at a steady, controlled pace. Overlap passes by about half the drum's width and never skip grit progressions.
If I decide to stain, how can I ensure an even color and avoid blotchy results?
To achieve an even stain, thoroughly clean all sanding dust before application. If working with softwoods or woods prone to blotching, apply a wood conditioner first to help the stain absorb uniformly. Always test your chosen stain color and application method on an inconspicuous area or scrap wood from your floor.
