Full Sanding vs Buffing: Why “Light Sanding” Isn’t a Real Process

If your timber floors are looking worn, patchy, or difficult to maintain, you may come across the term:

“light sanding”

It sounds reasonable.

But in practice, it creates confusion about what is actually being done to the floor.

The Two Real Processes

In floor sanding, there are two distinct approaches:

Full sanding

A full sanding process is used when the floor needs to be:

• cut back to remove a failing finish
• levelled
• cleaned back
• or properly prepared for a new coating

This involves working through the sanding sequence from coarse through to fine, finishing the surface ready for protection.

See our floor sanding page for full details on the sanding process.

Buffing and recoating

This is used when:

• the existing surface is still intact
• the goal is to refresh protection

It does not involve cutting back into the timber.

The Key Distinction

The real decision is not:

• full sanding vs light sanding

The real decision is:

Does the floor require full sanding,
or is it suitable for a buff and recoat?

When Full Sanding Is Required

Full sanding is typically required in three situations.

1. When an existing coating must be removed

Many floors are covered with:

• polyurethane coatings
• oils
• wax systems

If that surface has broken down, it needs to be removed.

This requires a coarse starting point.

Once that initial cut is made, the floor must be worked through the full sanding sequence to refine the surface properly.

2. When the floor needs levelling

New floors are not perfectly flat.

To produce a consistent, even surface, the floor must be levelled.

This process begins with a coarse abrasive cut.

Once levelling begins, the full sanding sequence follows.

3. When the floor is old, rough, or contaminated

Floors that have been:

• under carpet
• covered for years
• stained
• or exposed to heavy wear

must first be cleaned back.

Again, this requires a coarse starting point, followed by the full sanding process.

What Happens Once Sanding Starts

A coarse cut creates coarse scratch patterns.

Those scratches must be removed through a progression:

• coarse
• medium
• fine
• finishing passes

This sequence is what produces a flat, clean, finish-ready floor.

Once the coarse stage is required, the process is no longer partial.

It becomes a complete sanding system.

When Sanding Is Not Required

If the floor has:

• light surface wear
• no exposed timber
• no major defects

then it may be suitable for:

• buffing
• screening
• recoating

This does not involve full sanding.

Why the Difference Matters

These are not variations of the same process.

They are different approaches with different outcomes:

• full sanding restores the timber surface
• buffing and recoating refreshes the existing finish

Choosing the correct process depends on the condition of the floor.

The Bottom Line

• Floors either require full sanding, or they do not
• Full sanding follows a complete process from coarse to fine
• Buffing and recoating is a separate surface-level solution
• The correct method depends on the floor’s condition, not wording
