Hardwood Floor Pad Sander OBS 18″

The Clarke OBS-18 18″ Hardwood Floor Pad Sander is a high-quality orbital sander designed for fine sanding and finishing hardwood floors. Unlike drum sanders, which are aggressive and used for heavy material removal, the OBS-18 is a gentler, precision tool perfect for smoothing floors, removing surface imperfections, and preparing them for finishing. It is popular with professional floor refinishers and DIY enthusiasts who want to achieve a smooth, consistent finish on their floors.

Key Features:

• 18-Inch Rectangular Sanding Pad: The OBS-18 features a large 18-inch by 12-inch sanding pad. The wide sanding area allows for quick, efficient sanding over large surfaces, making it ideal for both residential and commercial projects.
• Orbital Motion: This sander operates with an orbital motion, which means the pad moves in small, circular motions rather than a straight line. Orbital sanding is less aggressive than drum sanding, reducing the risk of gouging the floor and making it perfect for light sanding or between finish coats.
• Powerful Motor: The OBS-18 is equipped with a robust motor (around 1 HP), providing consistent power for smooth, even sanding. The motor is designed to handle continuous operation, making it reliable for extended projects.
• Dust Collection System: The machine comes with a built-in dust collection system, often including a dust bag or the option to connect to a vacuum. This helps to reduce airborne dust and maintain a cleaner work environment, essential for achieving a high-quality finish.
• Heavy-Duty Construction: Clarke is known for its durable machines, and the OBS-18 is built to withstand heavy use. It features a metal housing and durable components, making it long-lasting even in professional settings.
• Gentle, Fine Sanding: The orbital motion of the OBS-18 ensures fine sanding and polishing, making it ideal for final sanding passes after rough sanding with a drum sander. It is also used for sanding between coats of finish or stain to smooth out minor imperfections.
• Ergonomic Design: The OBS-18 is designed with user comfort in mind. It features ergonomic handles and controls for easy maneuverability, reducing user fatigue during long sanding sessions.
• Easy Pad Replacement: The sanding pad can be easily replaced or swapped out for different grits, allowing users to switch between coarse and fine sanding pads quickly. This feature makes the machine versatile for different stages of the sanding process.

Typical Applications:

• Fine Sanding of Hardwood Floors: The primary use of the OBS-18 is for fine sanding and finishing. It provides a smooth, even finish on hardwood floors after the initial rough sanding has been completed with a drum or belt sander.
• Sanding Between Finish Coats: The orbital sander is ideal for lightly sanding between coats of stain, sealer, or polyurethane to smooth out any bubbles or imperfections, ensuring a perfect finish.
• Surface Preparation: The OBS-18 is used to prepare the surface of hardwood floors before applying the final finish, creating a clean, smooth surface that is ready for staining or sealing.
• Sanding Delicate or Soft Woods: Since it is less aggressive than drum sanders, the OBS-18 is well-suited for sanding delicate or softwoods, where more aggressive sanding could cause damage.
• Commercial and Residential Projects: The large sanding pad and powerful motor make the OBS-18 suitable for both large commercial areas and residential hardwood floors, providing efficiency and high-quality results.

Benefits of Orbital Sanders vs. Drum Sanders:

• Less Aggressive: Orbital sanders like the OBS-18 are less likely to gouge or leave marks on the floor, making them perfect for delicate sanding and finishing work.
• Easy to Use: Orbital sanders are generally easier to handle, even for beginners, as they do not require as much technique to avoid damaging the floor.
• Great for Finishing: Orbital sanders are ideal for the final sanding stages, as they provide a finer finish and can be used between finish coats for a smooth result.

Summary of Popular Models:

1. Clarke OBS-18DC Orbital Floor Sander:
   • Dust Control (DC) Version: The OBS-18DC comes with enhanced dust collection, making it a cleaner and more efficient option for sanding projects. It includes a large dust bag or the ability to connect to a vacuum system.
   • Power and Precision: The 1 HP motor and orbital motion provide smooth, controlled sanding for fine finishes.
2. Clarke OBS-18 (Standard Version):
   • The standard OBS-18 provides the same high-quality sanding performance without the advanced dust collection system of the DC model. It is a great option for those who need a solid, reliable orbital sander for hardwood floor projects.

Operation Tips:

• Use the Right Grit: For fine sanding, start with a medium grit (like 80) and finish with a finer grit (100 or 120). This will ensure the smoothest finish on the floor.
• Keep the Sander Moving: To avoid uneven sanding, always keep the sander moving across the floor and avoid staying in one spot for too long.
• Clean Between Passes: Use the built-in dust collection system or vacuum the floor between sanding passes to remove dust that can interfere with the sanding process and final finish.
