What size sandpaper does the Clarke EZ-8 use?

Depends on which version. The older clamping-bar EZ-8 uses 8×19.5 inch sheets. The newer expandable-drum EZ-8 uses 8×19 inch belts. The half-inch difference matters — the wrong size will not seat properly.

How do I tell which Clarke EZ-8 version I have?

Look at the top of the drum. A clamping bar version has a metal bar that hinges up and down. An expandable drum version has no bar — you will see a lever on the side for expanding the drum. Call the rental company if unsure.

Is the EZ-8 the same as the DU-8?

No. Both are Clarke 8-inch drum sanders, but different machines. The DU-8 only comes in a clamping-bar design and uses 8×19.5 inch sheets. The EZ-8 comes in two versions — one uses 8×19.5 sheets (older), the other uses 8×19 belts (newer).

What should I check on an EZ-8 at the rental counter?

Drum balance (no wobble when spun by hand), clamp-bar or expansion-lever mechanism functions smoothly, dust bag zipper closes fully, power cord intact, tilt mechanism holds position. Two minutes saves three hours.

Clarke EZ-8 Sandpaper Size Guide: Both Versions, Specs

By Matt Lipman · Reviewed by Professional Sandpaper Guide editorial team · Updated May 28, 2026 · NWFA-aligned

The clamping-bar Clarke EZ-8 takes 8 × 19.5-inch sheets — the same size as the DU-8 and Hiretech HT8. The newer expandable-drum EZ-8 takes 8 × 19-inch belts. Look at the top of the drum: a hinged metal bar means sheets, a smooth drum with a side lever means belts. The version identification is the only thing that matters before you buy sandpaper. This guide walks the diagnostic, the loading procedure for each version, the rental counter inspection, and the troubleshooting specific to both versions.

Three pre-rental checks

Before any drum sander:

Engineered vs solid floor? <3mm wear layer = no drum. Check.
Pre-1978 house? Lead test before sanding. Why.
Two separate 15A circuits? Sander on one, HEPA vac on the other. Setup.

For the full process see how to sand hardwood floors.

How to identify your Clarke EZ-8 version

This diagnostic is the article’s reason to exist. Look at the top of the drum:

Clamping-bar version (older)

A metal bar hinges up and down at one end of the drum
Sheets slide under the bar and tighten with a lever or knob
The drum surface itself is smooth and solid
Looks very similar to (and functionally identical to) a Clarke DU-8

Expandable-drum version (newer)

No clamping bar; the drum top is smooth
The drum has a seam running its length (the expandable sleeves)
A lever on the side expands and contracts the drum
Belts wrap around the drum and the expansion locks them in place

If unsure: call the rental shop and ask “is it the clamp-bar version or the expandable drum?” They know instantly. Getting this wrong is a wasted trip to the supplier.

EZ-8 rental counter inspection — 90 seconds

Same drum-sander basics either version, plus a version-specific check.

Both versions:

Roll the machine with the drum down (motor off). Tracks straight, or pulls? Pull = swap machines.
Spin the drum by hand. Smooth, or wobble/tick? Wobble = swap.
Power cord end-to-end for nicks. Any damage = swap.
Dust bag zipper closes fully. Quarter-inch gap = ask for a new bag.
Tilt mechanism holds position when released. Loose tilt = how floors get dished.

Clamp-bar version only:

Open the clamp bar, close it, open it again. Should hinge smoothly and lock tight. Sloppy lock = sheet slips mid-pass.
Check the drum surface for old adhesive residue. Clean drum = sheet seats square.

Expandable-drum version only:

Pull the expansion lever fully and release. Should expand and contract crisply. Sticky lever = belt won’t seat properly and you’ll fight loose belts all day.
Check the drum for groove wear from previous renters. Worn grooves = belt won’t hold tension; you’ll see chatter marks.

If anything fails: next EZ-8 in the rack.

Clamping-bar version — 8 × 19.5” sheets

The older EZ-8 uses 8×19.5” clamping-bar sheets. This size also fits:

Clarke DU-8 — DU-8 machine guide
Hiretech HT8

It does NOT fit the newer expandable-drum EZ-8 (uses belts) or the Silverline SL-8 (uses 8×20-1/8”).

Loading sheets (clamp-bar version)

Turn off and unplug the machine.
Open the clamp bar (hinges down at one end of the drum).
Slide the new sheet under the bar, aligning the short edge with the drum edge.
Tighten the clamping lever — snug, not over-tightened. Stripped lever mechanism = no recovery in the field.
Walk the machine forward gently (unplugged) to check for wrinkles. The sheet should wrap smoothly.
Trim or fold any excess so nothing catches.

Tip: load the fresh sheet before you finish the current one. You’ll be in a rhythm and won’t fumble mid-room.

Sheet count, clamp-bar version

For a 400 sq ft room, red oak, full 36 → 60 → 80 → 100 sequence:

36 grit: 5 sheets
60 grit: 3 sheets
80 grit: 3 sheets
100 grit: 3 sheets (skip if oil-based clear poly)

Adjust +50% on 36 grit for heavy old polyurethane. +25% across all grits for hard maple/hickory. Always buy one extra sheet per grit.

That’s an 18-sheet job; Amazon sells these as 50-sheet packs, so one pack per grit is three to ten jobs of inventory — the per-sheet cost beats rental-counter singles several times over, and the spares keep.

For the full math and worked examples, see our sheet calculator.

Expandable-drum version — 8 × 19” belts

The newer EZ-8 uses 8×19” belts (loops, not flat sheets). The 0.5” difference from the clamp-bar version is because:

8×19.5” sheets are cut flat; the 0.5” overlap covers the drum when clamped
8×19” belts loop around the drum; the loop circumference plus drum expansion holds them

The wrong size won’t fit or won’t function properly.

No verified per-grit belt listings yet — order 8×19” EZ-8 belts from the Virginia Abrasives Amazon store, confirming the 8×19” belt size on the listing before checkout.

Loading belts (expandable-drum version)

Turn off and unplug.
Locate the drum expansion lever (usually side or back).
Pull the lever to expand the drum.
Wrap the belt around the drum, aligning one edge with the drum edge.
Release the lever — drum contracts and locks the belt in place.
Belt should be held snugly by the drum’s grip.

If the belt slips after step 5, the drum expansion mechanism is worn — ask the rental shop to swap the machine.

Belt count, expandable-drum version

Same per-grit quantities as the clamp-bar version above. The math is identical; only the format changes.

EZ-8 vs DU-8 — which do you have?

Factor	DU-8	EZ-8
Model badge	”DU-8” clearly marked	”EZ-8” clearly marked
Design options	Clamp-bar only	Clamp-bar OR expandable drum
Sandpaper format	8×19.5” sheets always	8×19.5” sheets (older) or 8×19” belts (newer)
Market position	Professional/reliable	Budget/easier loading

Both are Clarke 8-inch residential drum sanders. Functionally near-identical except for sandpaper format.

EZ-8 troubleshooting (both versions)

Sheet/belt slips during operation

Clamp-bar: clamping lever isn’t tight enough — re-tighten one notch. If still slipping, drum surface has adhesive residue or the clamp mechanism is worn.

Expandable drum: expansion lever isn’t fully engaging, or the drum sleeves are worn. Pull lever harder. If still slipping, the drum needs service — swap the machine.

Uneven sanding / chatter marks

Not overlapping passes enough — overlap 3–4 inches
Moving too fast — slow your walking pace
Drum is out of alignment — swap the machine
Sheet was tensioned unevenly (clamp-bar) — re-load
Belt is bouncing on a worn drum sleeve (expandable) — swap the machine

Sheet/belt tears

Over-tensioning (clamp-bar): loosen one notch
Drum expansion too aggressive (expandable): swap the machine
Hit a nail or staple — inspect the floor and pull anything protruding before sanding

Burning smell

Stop immediately. Either the abrasive is glazed (worn smooth — replace) or the motor is overheating (let it cool 15 minutes unplugged).

Drum drops without warning

Worn tilt mechanism. Hold the handle the entire pass. Report on return.

Sanding technique (both versions)

Technique is identical regardless of version.

Grit sequence

For the standard NWFA sequence and which grit to stop at by finish type, see our 80 vs 100 grit decision guide and the grit chart.

Sanding best practices

Sand with the grain — always
Overlap passes 3–4 inches
Walking pace, no rushing
Light pressure — the weight and drum speed do the work
Empty the dust bag every grit change — outside, into a metal can with a lid (fire risk from compressed dust)
Edge separately with a Clarke 7R or hand-sanding after main sanding

Version first, then sheets. Get the version wrong and the sheets won’t seat. Get the sheets right and the EZ-8 is the most forgiving rental drum on the market.
