How to Choose the Right Buffer for Floor Sanding

Posted on October 4, 2023


Choosing the Right Buffer for Floor Sanding: A Comprehensive Guide

When it comes to floor sanding, choosing the right buffer is crucial to ensuring both the efficiency of the job and the desired finish. The buffer, also known as a floor polisher or floor machine, is used to smooth out the surface of wooden floors and prepare them for sealing or refinishing. A misstep in this selection process can result in a poor finish, increased labour, and potentially irreversible damage to the wood. Here’s a guide to help you make the right choice. First, consider the size and power of the machine. For large, open areas such as ballrooms or commercial spaces, a larger, more powerful buffer is essential to cover the ground efficiently. However, for residential spaces or rooms with tight corners, a smaller buffer will offer more maneuverability. It’s also vital to look at the motor’s horsepower and the rotations per minute (RPM) the machine can achieve. A machine with higher RPM will generally provide a smoother finish but also require more expertise to control. Lastly, take into account the type of floor you’re working on and the finish you desire. Different buffers can accommodate various pads and screens, and each is suited to different floor types and finishes. For instance, if you’re working on an old, thickly varnished floor, you might need a coarser pad or screen to break through the layers. On the other hand, a newly installed or lightly worn floor might require a finer pad to achieve a smooth finish. Always consult with professionals or do thorough research to match the buffer to your specific needs.

Understanding the Basics of Floor Sanding

Floor sanding is a process that rejuvenates wooden floors, bringing out their natural beauty and enhancing their lifespan. Whether you’re tackling a DIY project or simply want to understand what professionals do, here’s a breakdown of the basics of floor sanding. 1. Preparation: Before sanding begins, it’s crucial to prepare the area. This includes removing all furniture, fixtures, and any loose items from the floor. If there are any protruding nails or staples, these should be set below the wood’s surface or removed entirely. The floor should also be cleaned thoroughly to eliminate any dirt or debris, as these can cause scratches or uneven sanding. 2. Selecting the Right Equipment: Depending on the condition of the floor and the desired result, the right sanding equipment must be chosen. This includes both the sanding machine and the sandpaper grit. For heavily worn floors or those with deep scratches, you might start with coarse grit sandpaper (like 36 or 40 grit) and then progressively move to finer grits (like 80 or 100 grit) as the floor becomes smoother. 3. The Sanding Process: Floor sanding usually involves three main stages:
  • Rough Sanding: This is the initial stage where most of the old finish, imperfections, and deep scratches are removed using coarse-grit sandpaper.
  • Medium Sanding: This intermediate stage smooths the floor further, preparing it for the final finish. Medium-grit sandpapers, typically in the range of 60–80 grit, are used.
  • Fine Sanding: The final stage uses fine-grit sandpapers (like 100–120 grit) to give the floor a smooth finish, ready for staining or sealing.
4. Edge Sanding: Since large sanding machines can’t reach the edges or corners of a room, an edge sander is used to ensure these areas are sanded down to the same level as the rest of the floor. 5. Finishing Touches: After sanding, the floor is vacuumed to remove any residual dust. Then, a tack cloth or a damp rag is often used to pick up any remaining fine dust particles. Once the floor is completely clean, it’s ready for staining (if desired) and sealing with a protective finish. Understanding the basics of floor sanding ensures that the process is done correctly, leading to beautiful, long-lasting wooden floors. Whether you opt to hire professionals or tackle the task yourself, being informed will ensure you get the best possible results.

The Role of a Buffer in Floor Sanding

Floor sanding is an essential procedure to bring out the elegance and charm of wooden floors. While many are familiar with the more aggressive drum and belt sanders, the buffer, often overlooked, plays a pivotal role in achieving the perfect finish. Understanding the function and benefits of a buffer in floor sanding can help one appreciate the nuanced steps involved in floor restoration. 1. Intermediate Sanding: After the initial aggressive sanding with drum or belt sanders, there can be minor imperfections or swirl marks left on the floor. Buffers, equipped with the appropriate sanding screens or mesh discs, are ideal for this intermediate sanding phase. They smooth these marks and prepare the wood for the finishing touches, ensuring an even and consistent surface. 2. Fine Finishing: Buffers excel in the fine finishing aspect of sanding. Operating in a circular motion, they are designed to delicately abrade the wood surface without removing significant material. This function is especially vital after the floor has been stained. A buffer ensures that the finish applied on top will adhere properly and look smooth and uniform. 3. Versatility in Tight Spaces: While drum and belt sanders are bulky and can’t reach into corners or tight spaces, buffers are more maneuverable. Their design allows for closer access to walls, corners, and other challenging areas, ensuring the entire floor has a consistent finish. 4. Polishing and Final Sealing: Beyond sanding, buffers are also instrumental in the application and polishing of sealants, oils, and varnishes. They can be fitted with various pads suitable for applying these finishes or for buffing them to a high shine, thus enhancing the wood’s natural beauty. 5. Adaptability with Different Materials: While primarily used on wooden floors, buffers are versatile enough to be used on other flooring materials like marble, granite, or concrete. This adaptability means they can smoothen and polish a variety of surfaces, making them valuable assets in the floor restoration industry.

Different Types of Wood Floor Buffers

Wood floor buffers play a critical role in the maintenance and restoration of wooden flooring. Their primary function is to smoothen and polish wood surfaces, but the type of buffer one should use depends on the specific needs and the size of the project. Here are the main types of wood floor buffers available: 1. Standard Rotary Buffers:
  • Description: These are the most common types of floor buffers. They have a single, large pad that rotates in a circular motion.
  • Usage: Suitable for both sanding and polishing tasks. Rotary buffers are versatile and can be used with various pads and screens for different stages of floor treatment.
  • Size and Speed: They typically range from 13 to 20 inches in diameter and operate at speeds between 150 and 350 RPM.
2. Orbital Buffers:
  • Description: Unlike rotary buffers, orbital buffers have a rectangular base that moves in a small, oscillating motion. This movement ensures a more even and consistent finish.
  • Usage: Ideal for fine sanding and polishing, especially for floors with intricate patterns or inlaid designs.
  • Size and Speed: Usually smaller than rotary buffers, they operate at a higher RPM, often between 1,500 and 3,500 RPM.
3. High-Speed Burnishers:
  • Description: These machines operate at very high speeds and are primarily used to achieve a high-gloss finish.
  • Usage: Best suited for polishing tasks, especially when looking to achieve a mirror-like shine on the wood or on coated surfaces.
  • Size and Speed: They typically have a pad diameter of around 20 inches and operate at speeds between 1,500 and 2,500 RPM.
4. Random Orbit Buffers:
  • Description: These buffers combine both rotary and oscillating motions, ensuring a swirl-free finish.
  • Usage: Great for both sanding and polishing tasks. Their dual motion helps achieve a smoother finish without visible swirl marks.
  • Size and Speed: Size varies but usually falls between standard rotary buffers and orbital buffers. RPM can range widely based on the model.
5. Multi-Disc Buffers:
  • Description: As the name suggests, these buffers have multiple discs, each rotating independently, providing more aggressive sanding or polishing.
  • Usage: Suitable for large-scale projects or when rapid floor treatment is needed. They’re particularly effective on tough finishes or when levelling uneven surfaces.
  • Size and Speed: Often larger than other types, with varying RPMs depending on the model and intended function.
Choosing the right buffer type is crucial to achieving the desired finish and ensuring the longevity of the wooden floor. It’s always essential to match the buffer type with the specific needs of the project and to consider factors like floor condition, desired finish, and project scale.
