Description
A genuinely clean prepared face starts with the DED7767G16 — the coarse-grade abrasive in the Dedra DED7767 range, a 370 mm grit-16 disc that strips thick paint, levels stepped substrates, and clears proud adhesive at full machine speed, opening up the surface before the finer grit refines it.
Where the DED7767G16 Grit-16 Pad Performs Best on UK Preparation Work
Grit 16 is the aggressive end of the DED7767 abrasive range — the disc to fit when the substrate carries thick paint, proud adhesive ridges, or visible steps that must come off before any finer work begins. The 370 mm face cuts fast across painted masonry, weathered substrates, and EPS board faces where heavier levelling is needed, clearing in a single pass what hand-sanding cannot match in a day. It is stocked in the Renders World power floats and sponges range as the coarse grade of the DED7767 abrasive line.
Grit 16 is the coarser pair to the grit 24 disc, and the relationship matters: grit 16 strips fast and leaves visible scoring, and grit 24 follows to refine the surface before the wear-pad sequence begins. Used in order, the two grades cover heavy preparation in less total time than running grit 16 alone — a counterintuitive result, but one consistently borne out on site.
Why Trade Specifiers Choose the DED7767G16 Grit-16 Pad
- Grit 16 aggressive face: a coarse-grade cutter — the disc the trade reaches for when paint layers are thick or substrate steps need significant levelling.
- True 370 mm working diameter: covers more area per pass than smaller-class machines, accelerating heavy preparation on full elevations.
- Multi-substrate capable: strips paint, removes proud adhesive ridges, levels uneven masonry, and roughs down EPS faces during EWI installation.
- Time recovery on heavy work: reduces hand-sanding on stripping jobs from days to hours, freeing skilled time for the finishing stages that genuinely need it.

The disc attaches via the four-point Velcro on the DED776701 mounting disc with no adapter, so swapping grit grades on the same machine takes seconds. It fits the DED7767 platform only — the geometry is not interchangeable with the smaller DED7769 (375 mm class) or competing brands, so confirming the machine model before ordering avoids the most common cause of returns in this category.
How to Apply the DED7767G16 — Stripping Passes and Grit Sequence
Run the DED7767 at full 110 rpm and keep the disc moving in steady overlapping passes, because the grit 16 face is aggressive enough that pausing in one spot cuts a visible depression — even pressure across the full 370 mm contact area is what makes the disc work as designed, and tilting onto an edge digs deeper still and produces gouges that take significant flattening to recover. The disc suits stripping thick or layered paint before re-rendering, levelling stepped substrates, removing proud adhesive squeeze-out from board joints, and roughing weathered faces to provide a mechanical key.
The grit sequence is where the disc earns its place correctly. Grit 16 opens up the substrate and leaves scoring; the grit 24 disc follows to refine before the plastic flattening pad takes over. Skipping the grit 24 stage pushes the scoring problem onto flattening, which takes longer to resolve there than it would have at the abrasive stage. Where the prepared surface leads into a basecoat, the EPS adhesives and basecoats range covers the next material stage, and the Renders World guide to power floats for render finishing sets out the full pad progression.
Installation Notes — Pressure, Loading, Replacement
Engage all four Velcro corners onto the mounting disc before powering up, and keep light, even pressure across the full 370 mm face during work, because overloading one edge dulls the abrasive prematurely and produces uneven cutting. Inspect the face regularly: when the grit loads with paint residue or adhesive, cutting speed drops sharply and heat builds in the disc, so replacing it at that point is faster than persevering with a loaded face.
Heat management matters most on EPS. A loaded disc runs hot enough to soften and glaze the foam face rather than abrading it cleanly, so clear accumulated residue before it builds — brushing the face periodically keeps the cut fast and the disc cool. Store the disc flat in a dry container between sessions to protect the abrasive grit and the hook-and-loop backing, and replace once cutting speed no longer recovers after cleaning.
Pro Tips From UK Installers Using the DED7767G16
Grit 16 has a way of making operators feel productive — the disc cuts fast, debris flies, and an elevation looks stripped within minutes. The temptation is to run it longer than the job needs, on the logic that more cutting means a better surface for what follows. The opposite is usually true: switching to grit 24 sooner, while there is still scoring to remove, produces a better platform in less total time. Applicators consistently report that the mistake on heavy prep is not buying grit 16, but treating the disc as the whole solution rather than the first stage of one.
- Don't run it too long: switch to grit 24 while scoring remains, so refinement happens on the abrasive stage rather than at flattening.
- Keep the disc moving: the aggressive face cuts a depression if paused, so steady overlapping passes are essential.
- Let weight do the work: even pressure across the full face out-cuts forced edge-loading and leaves a more uniform surface.
- Clear loading early on EPS: a clogged face runs hot and glazes the foam instead of roughing it.
- Ease off if scoring runs deep: lighter passes leave a more uniform surface that grit 24 clears faster.
How the DED7767G16 Compares to the Grit-24 Refinement Disc
The same-stage decision in the abrasive range is grit 16 versus grit 24, and it is settled by how much material has to come off — the two discs work the same sanding stage on the same machine, chosen by grade. Grit 16 is the first-pass stripper; grit 24 is the refinement pass that follows it.
| Variant | Key Spec | When to Choose |
|---|---|---|
| DED7767G16 grit-16 disc (this) | Grit 16 · 370 mm · coarse | First-pass heavy stripping, aggressive levelling, EPS roughing |
| DED7767G24 grit-24 disc | Grit 24 · 370 mm · medium-coarse | Second-pass refinement, EPS smoothing |
For light surface preparation with little material to remove, starting on grit 24 alone is often sufficient. After both abrasive stages, the plastic flattening pad sets wall flatness before the texture-setting and closing wear pads complete the surface.
Is the DED7767G16 Grit-16 Pad Right for Your Project?
- Heavy paint stripping, significant levelling, or initial EPS roughing: a strong fit — the coarse grade removes material fast where finer discs stall.
- Second-pass refinement after stripping: fit the DED7767G24 grit-24 disc as the next stage before the plastic and finer wear pads.
- Light surface preparation only: starting on grit 24 alone is often enough when little material needs removing.
- Power floats outside the DED7767 platform: disc geometry and the Velcro pattern will not match — confirm the machine model first.
FAQ — DED7767G16 Use, Grit Choice, Longevity
How long does one DED7767G16 disc last in heavy stripping service?
Working life depends sharply on substrate. Stripping thick weathered paint consumes the abrasive significantly faster than EPS roughing or adhesive clearance. As a working guide, a single disc covers a substantial elevation of paint-stripping before cutting speed noticeably drops, and lighter applications stretch its life considerably further.
Will this abrasive disc fit power floats other than the Dedra DED7767?
The DED7767G16 is sized for the DED7767 platform — 370 mm diameter and a four-point hook-and-loop pattern matched to the mounting disc. It is not reliably compatible with the smaller DED7769 (375 mm class) or with other manufacturers' machines, so confirming the model before ordering avoids fitment issues.
When is grit 16 the right choice rather than grit 24?
Grit 16 is the first-pass disc when there is significant material to remove — thick paint, stepped substrates, or proud adhesive ridges that finer grades cannot clear in reasonable time. The grit 24 disc takes over for the refinement pass that follows. For light surface preparation only, starting on grit 24 alone is often sufficient.
Can the disc rough down EPS insulation board faces?
Yes — grit 16 handles initial roughing of EPS faces where significant material removal is required, such as proud adhesive ridges or stepped board joints. For lighter EPS smoothing where the face only needs final levelling, the grit 24 disc is the safer choice, since it removes less material per pass and reduces the risk of cutting too deep.
What if grit 16 leaves scoring deeper than expected?
Visible scoring after grit 16 is normal and is removed by the grit 24 refinement pass. If scoring runs unusually deep, ease pressure on subsequent passes — the disc cuts through weight rather than force, and lighter, even passes leave a more uniform surface than aggressive loading does.
