DIY Floor Sanding Tips for Beginners

Understanding the Need for Sanding

1. The Ageing Process:

Wooden floors are susceptible to wear and tear. Foot traffic, furniture movement, pet scratches, or even sunlight exposure can lead to a dull and worn-out appearance.

2. Revealing Hidden Beauty:

Beneath the worn-out layer is a fresh wood layer, waiting to be unveiled. Sanding removes the top layers of damage, revealing the undamaged wood beneath.

3. Prepping for a Fresh Finish:

If you’re thinking of staining or resealing your wood, sanding is a crucial first step. It creates a smooth, even surface for the new finish to adhere to.

Getting Started: The Right Tools

1. Floor Sander:

A heavy-duty tool, it’s designed to sand large areas quickly. The most popular types include drum sanders or orbital sanders. They can be rented from hardware stores.

2. Edge Sander:

This smaller tool is perfect for corners and edges where the floor sander cannot reach.

3. Hand Sanding Blocks and Paper:

For the very fine details and hard-to-reach spots.

4. Safety Gear:

This includes dust masks, ear protection, and safety goggles. Sanding produces a lot of dust and noise.

The sanding process

1. Prepare the area:

  • Clear the room: Remove all furniture, rugs, and any other items from the floor.
  • Clean: Ensure the floor is free from dirt and debris. This helps prevent unwanted scratches during the sanding process.
  • Seal the room: Use plastic sheets to block doors and windows, preventing dust from spreading to other parts of your home.

2. Start with the floor sander:

  • Choose the right grit: For floors with deep scratches or old paint, start with a coarse grit like 36 or 40. For mildly worn floors, a 60-grit might suffice.
  • Go with the grain: Always sand in the direction of the wood grain to avoid cross-grain scratches.
  • Keep it moving. Never let the sander sit in one spot while it’s on. It can create divots or uneven surfaces.

3. Corners and edges:

Once the main area is sanded, switch to the edge sander. Use the same grit you started with on the floor sander. Sand until the edges are as smooth and even as the rest of the floor.

4. Progress to Finer Grits:

After the initial sanding, move to a finer grit paper, like 80-grit, and repeat the process. Finish with an even finer grit, such as 120, to ensure a super smooth finish.

5. Hand Sanding:

For areas where even the edge sander can’t reach or for spot treatments, hand sanding might be necessary.

Post-Sanding Tips

1. Clean Up:

Sanding produces a lot of dust. Vacuum the floor using a soft brush attachment. Follow this with a tack cloth to pick up any remaining dust.

2. Inspect:

After cleaning, inspect the floor for any uneven spots or missed areas. Lightly hand sand if necessary.

3. Finish or stain:

Once satisfied, you can apply your chosen stain or finish. Remember to follow the manufacturer’s instructions and ensure the room is well ventilated.

Common Mistakes to Avoid

Skipping Grits:

Do not jump from a very coarse grit to a very fine grit. This can leave deep scratches that the finer grit can’t remove.

Not Prepping the Room:

Failing to seal off the room or clean the floor can lead to more dust and potential damage.

Rushing the Process:

Sanding is labor-intensive. But rushing can result in mistakes. Take your time for a smooth, even result.

Not Assessing the Floor Condition:

Before you start, thoroughly inspect the floor for any signs of deep damage, warps, or persistent stains. Not assessing the condition can lead to unsatisfactory results and may even exacerbate existing issues.

Neglecting Safety Precautions:

Sanding can be a messy and potentially hazardous task. Not wearing appropriate safety gear, like masks and goggles, can put you at risk of inhaling dust particles or injuring yourself.

Not maintaining the sander:

Not properly maintaining the sander by not checking the belts or the sandpaper regularly can lead to inconsistent results. Always ensure the sander is in good condition before starting your project.


Anxious to get rid of imperfections, beginners might sand too much, which not only wears down the wood faster but can create dips and grooves in the floor, leading to an uneven surface.

Ignoring Room Corners:

Often, the corners of the room are neglected, which can result in a noticeably unfinished look. Make sure you pay attention to the corners and edges for a uniform finish.
