Best Detail Sander for Wood Restoration: 2025 Expert Review

Published 16 December 2025

Restoring timber, particularly sash windows, is a labour of love. In York's Victorian terraces, we often face windows covered in a century's worth of gloss paint. The hardest part isn't the structural repair; it is getting the timber back to a smooth finish without destroying the delicate mouldings.

A standard orbital sander is simply too bulky for glazing bars and corners. You need a detail sander (often called a mouse sander) that can get right into the rebate without rounding off the sharp edges of the joinery.

In this review, I'm looking at three sanders that suit different needs: a robust budget corded option for bench work, a cordless model perfect for working up a ladder, and a compact unit for those awkward tight spots.

Specs vs. The Real World

The Spec: "Dust Collection Claims"

The Theory

"Manufacturers claim the little plastic box catches all the dust, keeping your workspace clean."

The Reality

On a site, these boxes fill up in minutes and fine dust still escapes. For restoration work, especially with old lead paint, you must wear a mask and ideally connect the sander to a proper extraction unit.

The Spec: "High RPM (Speed)"

The Theory

"Higher speed (13,000+ RPM) means faster work."

The Reality

High speed creates friction heat. On pine sash windows, this can melt old varnish or paint, clogging your sandpaper instantly. Sometimes a lighter touch and better technique are worth more than raw speed.

My Top 3 Recommendations

Three options to cover different needs and budgets

Detail Sander Electric: DEKOPRO 180W Mouse Sander

Budget Pick
Detail Sander Electric: DEKOPRO 180W Mouse Sander

DEKOPRO

For a corded unit under £20, this offers impressive power (180W) compared to others in its class. It is aggressive enough to strip back flat timber sections on a sill or bottom rail but compact enough for corners. Ideally suited for bench work where you have easy access to a socket.

Price£16.99 (at time of writing)
Power180W Motor
Speed13,000 RPM
The Good
  • Powerful 180W motor handles stripped pine well
  • Includes 15 sanding sheets to get you started
  • Excellent value for money for DIY restoration
The Bad
  • Corded design can be a nuisance up a ladder
  • Dust collector is small (common for this size)

Installer Tip:

Because this has a punchy 180W motor, go easy on the pressure. Let the tool do the work. If you press too hard on softwoods like European Redwood (common in York), you'll create dips in the surface that show up when painted.

Cordless Detail Sander: DEKOPRO 20V Sander with Dust Collector

Quality Pick
Cordless Detail Sander: DEKOPRO 20V Sander with Dust Collector

DEKOPRO

When you are halfway up a sash window frame, the last thing you want is a trailing lead keeping the window open or tripping you up. This 20V cordless option provides the freedom to work safely on vertical stiles and headers. The dust-sealed switch is a vital feature for longevity in dusty joinery environments.

Price£37.99 (at time of writing)
Voltage20V Cordless
ProtectionDust-sealed switches
The Good
  • No trailing cables - essential for window restoration in situ
  • Dust-sealed components extend the tool's life
  • Pure copper motor runs cooler than cheaper alternatives
The Bad
  • Heavier than corded versions due to the battery
  • Battery life limits continuous sanding time

Installer Tip:

Keep the battery charger handy. For a full bay window restoration, sand the upper sashes with this cordless unit, then switch to a corded sander for the sills and lower sections to save battery life.

KATSU Tools Electric Detail Sander, 130W Palm Sander

KATSU Tools

Whilst less powerful at 130W, this lighter touch is actually a benefit when working on delicate glazing bars or fragile mouldings where a heavy-duty sander might be too aggressive. Its compact palm design allows for excellent control in tight corners.

Price£16.99 (at time of writing)
Power130W Motor
DesignCompact Palm Grip
The Good
  • Lower wattage offers gentle control for delicate mouldings
  • Very compact design gets into tight rebates
  • Effective hook and loop system
The Bad
  • Not powerful enough for stripping large flat areas fast
  • Vibration can be higher on smaller units

Installer Tip:

This is the 'finishing' tool. Use a scraper to remove the bulk of the old paint, then use this sander with 120 or 240 grit to smooth the timber before priming. It is perfect for the intricate profiles found on Victorian architraves.

Frequently Asked Questions

Can I use a detail sander to strip paint from sash windows?
Yes, but be careful. Detail sanders are great for the final smoothing. If you have thick layers of gloss paint (common in York homes), I recommend using a heat gun or chemical stripper first to remove the bulk, then using the sander to finish the timber. Sanding layer upon layer of paint will just clog your paper immediately.
What grit sandpaper should I use for old pine?
For Victorian pine, start with 80 grit to remove imperfections, but don't stay there too long as you'll scour the soft grain. Move quickly to 120 grit, and finish with 180 or 240 grit before oiling or painting. If you're using Accoya for repairs, 180 grit gives a lovely finish.
Is a cordless sander powerful enough for professional use?
Modern 20V tools are excellent. Whilst a corded 180W sander might have more raw torque for bench work, the cordless option is invaluable when working on a scaffold or ladder to restore upper sashes. The trade-off is runtime, so we usually carry spare batteries.
Do I need to replace my rot-affected sashes or just repair them?
It depends on the extent of the damage. At DR Joinery, we favour restoration. Often, only the bottom rail or sill is rotten. We can splice in new timber (ideally Accoya or hardwood) and keep the original box frame. It's cheaper and retains the property's character.
How do I deal with lead paint dust?
Many pre-1960 properties in York have lead paint layers. Safety is critical. Always wear a P3 rated mask, keep the area ventilated, and dampen the surface slightly if scraping. Using a sander with a vacuum attachment is better than the dust bag alone.
