Can You Sand Bamboo Floors: Unveiling the Truth

Bamboo flooring has gained popularity because of its environmental friendliness. It is durable, long lasting and versatile. This fast-growing grass reaches maturity in a quarter of the time of deciduous trees, making it less expensive than hardwood.

Coming Up On This Page

Bamboo floors attract more and more users because they produce sustainable building materials. However, care and refinishing are required for a longer life. Revive the look of your floor by protecting it from further damage, sanding it down and refinishing it with a wood floor varnish.

Exploring Bamboo as a Flooring Material

The unique characteristics of bamboo

  • Flexible 
  • Lightweight
  • Stronger
  • Affordable
  • Excellent permeability
  • Easiness to straighten 

Environmental benefits of bamboo flooring

  • Sustainable 
  • Flexible
  • Stable
  • Renewable 

Durability and resistance to wear

What makes bamboo flooring tough and durable is the dense and hardwood that is structurally stable, and tough. It lasts as long as fifty years. Give careful attention and maintenance. It is also termite-resistant.

When Sanding Bamboo Floors Makes Sense

Identifying signs of wear and damage

  • Discoloration
  • Warping 
  • Planks lifting up

Assessing the thickness of the bamboo layer

Bamboo flooring features thicknesses ranging from 10mm to 15mm, depending on the style and type of flooring you choose. The planks’ thickness depends on how the flooring has been designed and manufactured.

Reasons for considering sanding as a solution

Removing dust makes your workplace more efficient. A dust-free environment reduces time to completion, meaning short working hours. 

The Sanding Process: Step-by-Step

Preparing the room and floor

Start with a clean workspace, making sure to tape up the room to stop the dust from traveling elsewhere in your house. Clean the subfloor dry and level. Check for moisture using a concrete moisture meter for the newly laid concrete subfloor.

Choosing the right sandpaper grits

Each sandpaper grit matches a certain coarseness of the floor. For the best finish, the floor should be sanded in stages with finer abrasives. Start with grit 40, then grit 60, and grit 100. The first coarse abrasive removes the old surface coating and flatten the surface.

Using the appropriate sanding equipment

It would help to have a circular saw or jigsaw, an electric hand sander (orbital palm sander), a dust mask, and safety goggles. The sandpaper you use will depend on how smooth you want your bamboo floors to be. The standard fine-grit paper ranges between 60 and 80 grit. If your bamboo floors are already in good shape, try the 60-grit paper but if they are worn down, an 80-grit will be ideal (Toolstop.co.uk). .

Executing the sanding process correctly

Bear in mind that bamboo is softer than most of the hardwood species. The sandpaper used in the bamboo floor restoration has to be finer. For bamboo restoration and finishing after installation, buffing alone can be enough.

Potential Challenges and Risks

Risk of over-sanding and damaging the floor

Over-sanding in a single place can leave your floor uneven or distorted. It results from trying so hard to sand down a knot, bump, defect, or a hard patch of wood. You end up damaging the floor. 

Dealing with splinters and raised fibers

To remove splinters, use a vacuum cleaner with a soft brush attachment or a damp mop or cloth. Do not saturate your floors with water, which can damage the wood.

Minimizing dust and debris during sanding

Avoid pressing too hard or lingering in one spot when sanding. That could cause uneven sanding and create more dust. Consider a vacuum with a HEPA filter to remove dust from the floor and surrounding surfaces between each sanding stage.

Sanding Techniques for Different Bamboo Types

Solid bamboo flooring

Solid bamboo flooring is made from strips of bamboo laid in either a horizontal or vertical formation. These strips are glued to create the planks using a thin grain pattern (vertical) or a wider grain pattern (horizontal). Solid bamboo flooring is versatile and works on any subfloor.

Engineered bamboo flooring

Engineered bamboo flooring is from a cross-laminated wood substrate, in which layers of plywood are glued to one another using their grain directions alternating. It is durable, stable, and does not expand or shrink with climate change. 

Strand-woven bamboo flooring

Strand woven bamboo flooring is bamboo fibers, compressed under extreme pressure to form a plank. It is eco-friendly and hard-wearing. Strand woven bamboo flooring is durable and stable.

Finishing Options After Sanding

Staining bamboo floors

  1. Clean workspace
  2. Sand the surface
  3. Clean the floor and remove splinters
  4. Fill any scratches
  5. Apply the stain
  6. Apply the finishing coats

Applying protective sealants

Natural waxes can seal bamboo surfaces, giving a protective layer that repels moisture and enhances the bamboo’s natural beauty. Rub the wax onto the bamboo surface and buff it to a desired sheen. Linseed oil works better on old floors.

Choosing between matte, semi-gloss, and high-gloss finishes

For an elegant shine and durability, a high-gloss paint finish is one of the best options for your application. High-gloss paints offer reflectivity and are the easiest to clean compared to semi-gloss, satin, eggshell, and matte finishes.

Caring for Newly Sanded Bamboo Floors

Set up proper cleaning routines, use rugs and furniture pads to prevent damage, and humidity levels to maintain the finish. Vacuum, dust, or wipe with a dampened mop and remove marks and stains using water and vinegar.

Alternatives to Sanding: Bamboo Floor Restoration

Screening as an alternative to sanding

Screening involves a mesh encrusted with abrasive particles and fewer abrasive particles per square inch, making it less aggressive than sandpaper.

Replacing damaged bamboo planks

You may remove the damaged area between the two ends of the plank, or remove the section of the plank from the damaged area. 

Refinishing without complete sanding

You may not sand your floors but use a buffer to scuff-sand, then apply one or two coats of finish. 

Long-Term Maintenance and Preservation

Regular cleaning and maintenance tips

  • Remove dust and dirt daily 
  • Clean regularly
  • Wipe away spills promptly
  • Avoid scratching your bamboo floor
  • Remove outdoor footwear

Periodic resealing and finishing touch-ups

Sand them with fine-grit sandpaper until they are smooth with zero flaws. Apply a new protective seal coating. Make sure it is clean, sand it down, and refinish it using a wooden floor lacquer.

Increasing the longevity of sanded bamboo floors

  • Allow the floor to acclimatize for at least 48 to 72 hours post-installation before setting heavy furniture on it
  • Use felt pads under the furniture legs to prevent scratches on the finish
  • Consider professional maintenance services
  • Place protective pads under furniture legs
  • Lift furniture when moving it instead of dragging it
  • Use a dolly when moving heavy objects

  • Clean up spills as quickly as possible

Summary: Enhancing the Lifespan of Your Bamboo Floors

Sanding extends the life of your bamboo floors. Before you apply any seal or finish, sanding increases the adhesion of your surface. That means your finish becomes durable enough not to crack or peel sooner than expected. Keep the surface clean and dry. Do not put heavy furniture on top of the floors. 

Frequently Asked Questions (FAQs)

Can bamboo floors be sanded multiple times?

Bamboo floors can withstand multiple sanding sessions, but the limit hinges on factors like wear layer thickness, flooring quality, and sanding expertise. Thicker wear layers permit more sanding. Bamboo floors typically have 1.5mm to 4mm wear layers or more.

Excessive sanding can harm the floor by wearing down the wear layer. Sand bamboo floors sparingly to refresh their appearance or eliminate deep imperfections.

Professionals, well-versed in bamboo flooring, should handle sanding to prevent damage. They assess the floor’s condition and decide how many safe sanding rounds it can endure.

Routine upkeep and protective measures, like using rugs and mats in high-traffic areas, extend bamboo floor lifespan, reducing the need for frequent sanding.

What tools are required for sanding bamboo floors?

For effective bamboo floor sanding, you’ll need:

  • Sanding Machine: Choose between an orbital sander or a drum sander, depending on your experience and project size.
