The Ultimate Guide to Floorboard Sanding Techniques

Posted on May 1, 2023


A Comprehensive Guide to Different Types of Floorboard Sanding Techniques

Floorboard sanding is a crucial process in the maintenance and restoration of wooden floors. The technique helps to remove the top layer of the floorboard, which may have been worn out, damaged, or stained over time. By sanding the floorboards, you can create a smooth and even surface, which can then be finished with a protective coating to enhance the appearance and durability of the floor. In this comprehensive guide, we will explore the different types of floorboard sanding, the benefits they offer, and the best technique for your specific needs. Floorboard Sanding Techniques

1. Drum Sanding

Drum sanding is a traditional and common method of floorboard sanding. It involves using a large, heavy drum sander that has a cylindrical sanding surface. This method is powerful and efficient, making it suitable for large areas and heavily worn or damaged floors.   Pros:  
  • powerful and efficient for removing deep scratches, dents, and stains
  • Ideal for large areas and commercial spaces
  • Can handle various grit sizes for different levels of smoothness.
  • Can cause damage to the floor if not used correctly.
  • not suitable for thin or delicate floorboards
  • Can be difficult to manoeuvre in tight spaces.

2. Orbital Sanding

Orbital sanding uses a flat, rotating sanding pad, making it gentler than drum sanding. This method is suitable for small or tight spaces and offers better control for a more even finish. Orbital sanders can handle various grit sizes, making them versatile for different levels of smoothness.   Pros:  
  • more control and precision than drum sanding
  • Suitable for thin or delicate floorboards
  • Ideal for small or tight spaces
  • less risk of damaging the floor
  • less powerful than drum sanding
  • It may take longer to complete larger jobs.

3. Random Orbital Sanding

Random orbital sanding is a combination of both orbital and drum sanding techniques. It uses a sanding pad that both rotates and oscillates, providing a more aggressive sanding action than regular orbital sanders. This method offers the best of both worlds, with the power of drum sanding and the control of orbital sanding.   Pros:  
  • Combines the power of drum sanding with the control of orbital sanding.
  • Suitable for a wide range of floor conditions and sizes
  • Can handle various grit sizes for different levels of smoothness.
  • Can be more expensive to rent or purchase than other sanders.
  • May require more experience to operate effectively.

4. Hand Sanding

Hand sanding is the most basic and traditional method of floorboard sanding, involving the use of sandpaper and manual labour. This technique is best suited for small areas or spot treatments and is often used for detail work and fine finishing.   Pros:  
  • Offers the most control and precision
  • Inexpensive and requires minimal equipment
  • Ideal for small areas, spot treatments, and detail work
  • Labor-intensive and time-consuming
  • Not suitable for large areas or heavily worn floors

5. Dust-Free Sanding

Dust-free sanding is an innovative technique that utilizes a dust extraction system to collect and remove dust particles during the sanding process. This method offers a cleaner and healthier work environment, making it an ideal choice for homes or commercial spaces where air quality is a concern.   Pros:  
  • Minimises dust and debris during the sanding process.
  • Provides a cleaner and healthier work environment.
  • Can be used with various types of sanders (drum, orbital, random orbital).
  • Can be more expensive due to the specialised equipment required.
  • May not be completely dust-free, depending on the system used.

6. Belt Sanding

Belt sanding is another popular method of floorboard sanding, which uses a continuous loop of abrasive material (the belt) wrapped around two drums. The belt moves at high speeds, effectively removing the top layer of the floorboard. This method is suitable for large areas and can handle various grit sizes for different levels of smoothness.   Pros:  
  • Fast and efficient, especially for large areas
  • Can handle various grit sizes for different levels of smoothness
  • Suitable for heavily worn or damaged floors
  • Can cause damage to the floor if not used correctly
  • not suitable for thin or delicate floorboards
  • Can be difficult to manoeuvre in tight spaces.

7. Corner Sanding

Corner sanding is a specialised technique that focuses on the corners and edges of the room, where larger sanding machines may have difficulty reaching. This method typically uses a handheld or small sanding tool to carefully sand the hard-to-reach areas for a complete and uniform finish.   Pros:  
  • Ensures a thorough and even finish in corners and edges.
  • Allows for better control and precision in tight spaces.
  • Can be used in conjunction with other sanding methods.
  • Not suitable for large areas or as a standalone sanding method.
  • Can be time-consuming.

8. Buffer Sanding

Buffer sanding, also known as a floor polisher, uses a circular pad that oscillates to sand and smooth the floor’s surface. This method is typically used as a final step in the sanding process to create a uniform and polished finish. Buffer sanding can also be used to buff and polish the final protective coating applied to the floor.   Pros:  
  • Provides a smooth and polished finish.
  • Ideal for finalising the sanding process.
  • Can be used to buff and polish the protective coating.
  • Not suitable for heavy-duty sanding or removing deep scratches.
  • May require additional equipment, such as a floor buffer.
