How To Fix Over-Sanded Wood?

Apr 8, 2024

Despite being a durable flooring option, wood surfaces often face staining, scratches, scuff marks, and more. And sanding is one of the best ways to fix these imperfections and restore your wood floors to their flawless state.

However, sanding can be an extensive process to carry out, which makes it very prone to mishaps, one of them being over-sanding. When sanding goes overboard, it ends up leaving the wood over-sanded. That results in an unsightly and uneven surface on your floors.

But, don’t fret! If you’ve mistakenly over-sanded your wood floors, here is what caused it and the way you can fix it.

What Causes Over-Sanded Wood?

Before we move on to fixing the problem, let us first briefly see what leads to it. Over-sanding is when you sand your wood floor beyond its need. It is often a result of either of these two actions.

→ Prolonged sanding in one spot in an attempt to fix a stain or imperfection

While sanding your floors, if you try to keep your sander working on the same spot in order to remove a stain, mark, or any fault, it can lead to an over-sanded spot on your wood. The longer the machine sits on a spot, the more the chances of getting an unevenly sanded surface.

→ Continuous sanding with increasingly fine grits beyond the limit

Oversanding also occurs when you do not stop after a certain fine grit and keep on sanding with even finer grits to achieve a smoother finish. This often happens when you sand beyond 180 grit level which leads to excess sanding and removal of too much wood material. The fine dust will clog the wood grain’s pores, hindering further staining and coating.

5 Steps To Fix Over-Sanded Wood

The solution to fix the over-sanded wood is to sand the rest of your wood floor down to the level of the over-sanded spot. By doing so, the spot will blend well with the entire floor and your wood will be levelled properly, fixing the issue.

Step 1: Clean the floor first

Before you start to fix the over-sanded wood, begin with cleaning the area first. Give it a sweep or a dust-mopping pass to ensure all the surface dirt is out of your way. This will remove the abrasive grit and protect your wood floors from damage.

Step 2: Identify and mark the over-sanded spot

Look for the portion, section, or area that has an over-sanding spot or dip. Once you’ve identified it, you need to mark it.

Take a pencil and shade the spot as well as the area around the spot lightly. This is a useful trick that experts use when fixing an over-sanded wood.

When you mark it with a pencil, the shade will tell you what level you need to keep sanding at. First, the pencil mark around the spot will disappear, and lastly, the mark in the spot will go away, which tells you’ve levelled up the wood.

Step 3: Choose the right sandpaper grit

But before you sand, choose the right sandpaper grit as per the severity of the spot. If the over-sanded area is deep, you will need to start with a coarse grit and keep moving to a finer one. And if the spot is light, starting from a medium to fine grit will do the job.

Step 4: Sand the wood

Once you’ve marked the spot with a pencil and chosen the grit accordingly, sand the wood floor as you normally do.

But be sure that, this time, you aren’t overdoing it. Going at a steady pace throughout sanding is ideal.

Start with 60-grit sandpaper and keep sanding until the pencil mark goes away. Mark the shade again and move on to a finer grit of 80. Repeat the process for 120, 150, and 180.

As you sand, you will gradually see the over-sanded spot on wood blending with the rest of the surface. The moment that happens and the pencil mark inside the spot goes away, you can stop sanding. This is where you’ll get your wood levelled and the over-sanded wood fixed properly.

Step 5: Final clean-up after sanding

Once you’ve sanded your floor and blended the wood, you can clean up the sanding dust. This step is crucial especially if you are planning to stain and refinish your newly-sanded wood after fixing it.
