Description
Renders World lists the DED776701 as a spare part rather than an add-on, and the paragraphs below set out what the Dedra manual fixes about the plate before the ordering detail follows. It sits in the power float and finishing sponge range alongside the machine it belongs to.
What the Backing Plate Does on a Dedra DED7767
A mounting pad for render power float work sits between the spindle and the wear disc on the 710 W Dedra DED7767, held by a single screw, so a tired hook-and-loop face is swapped without touching the machine. The manual describes exactly that arrangement: the plate goes onto the spindle pin and is tightened with a screw, and the working ends attach to the plate by hook-and-loop.
That makes the plate the one part in the assembly that every other disc depends on, and it is also the part the manual treats as structural rather than consumable — it appears in the assembly drawing as the mounting disc with hook-and-loop, alongside the screw and the spindle it locks against.
- Named in the assembly: the manual's parts list carries the mounting disc with hook-and-loop as item 3, with the screw as item 2 and the spindle as item 4.
- Fitted before anything else: the manual's preparation section puts the plate on first, and only then the sponge, plastic or working disc on top of it.
- Order unit: one plate at £35.90, shown as available, read from the product endpoint in August 2026.
Why This Plate Is a Spare Part, Not a Missing Component
One line in the manual changes how this listing should be read, and it is good news for anyone pricing a first kit. The plate ships with the machine, so a new DED7767 arrives ready to take a wear disc and needs nothing added for floating work.
- Supplied in the box: the packing list runs to the machine, the mounting disc, a plastic disc with mesh, a sponge plate, a set of screws, a screwdriver and a set of carbon brushes.
- Not on the accessory list: the three codes the manual offers for separate purchase are DED77671, DED77674 and DED77675 — the plate is not among them, which is consistent with it already being supplied.
- Bought when the face gives up: a replacement restores grip for every disc that attaches to it, which is cheaper than treating a slipping pad as a pad problem.
- Bought as a second plate: a spare keeps a machine earning while a contaminated face is cleaned properly rather than in a hurry between elevations.
- Identified by code: the Dedra DED776701 machine mounting pad is listed here under SKU DED776701 and EAN 5902628776839, which is the cleanest reference for a purchase order.

One row there deserves reading carefully rather than lifting. The Dedra DED7767 render smoothing machine declares a 390 mm disc diameter at 110 min⁻¹ in its technical data table, and the manual does not say whether that figure describes the mounting plate or the working disc fitted to it — so it is published here as the machine's declared figure and no diameter is claimed for the plate itself. Where a plate is being matched to discs already on the van, measure the one being replaced. No VAT treatment is displayed beside the £35.90 figure, so none is stated here.
Fitting a Replacement Plate in the Manual's Order
Assembly is short, and keeping to the documented order is what lets the new plate seat square. Every preparatory step is carried out with the machine disconnected from the supply.
- Isolate the machine and remove the existing plate by releasing its screw.
- Clear the residue from the spindle and the plate seat, which the manual's general instruction to keep the tool free of build-up covers directly.
- Fit the new plate to the spindle pin, matching the hole to the shape of the pin so it locates rather than sits proud.
- Tighten it with the screw, using one from the set supplied with the machine if the original is missing.
- Press the working disc onto the plate, where the hook-and-loop face holds it, and check that it seats evenly all the way round.
- Start the machine horizontally and clear of the surface, holding the safety button on the left of the main handle before the switch, and let it reach full speed before it touches the work.
Stance carries more of the load than downforce once work begins: the manual asks for a stable position with feet slightly apart and the torso leaning in, and for semi-circular movements with the pressure matched to the task. The Renders World guide to power float finishing techniques works through how those passes sequence across a wall.
Keeping the Plate, the Discs and the Motor in Service
The intervals on this platform are short, documented and easy to diarise, and keeping to them is what makes output steady across a working week.
- Check the disc before every start: the manual asks for a check that it is not worn out, and for work to be done with serviceable working ends only.
- Treat poor efficiency as a disc question first: the fault table gives a worn disc as the cause of low working effectiveness, with replacement as the remedy.
- Clean down after every session: the manual requires residue to be cleared from the tool at the end of work, which is what keeps a hook-and-loop face gripping.
- Clear the air inlets: flagged as very important, best done with compressed air, since blocked vents are the manual's stated cause of overheating.
- Work in spells: permissible working conditions are S2, 15 minutes, and the machine is Class II, IP20 with damp to be avoided.
- Watch the brushes: checked no less often than every 20 to 30 working hours and replaced below 5 mm, with a spare set already in the box.
Hearing protection is a manual requirement rather than a preference, alongside eye and respiratory protection: sound pressure is 83.4 dB(A) and sound power 94.4 dB(A), both with 3 dB(A) uncertainty, determined to EN 60745-1:2009. Declared vibration at the handle is below 2.5 m/s² with an uncertainty of 1.5 m/s², measured to EN 60745-2-3:2011.
Which Discs Attach to the Plate, and How to Order Them
The plate accepts the working discs by hook-and-loop, and the manual is clear about two of them while leaving a question open on the other two. Knowing which is which before ordering saves a return.
- Plastic disc with mesh — supplied: the manual gives it for floating larger unevenness, or plaster that has dried too far.
- Sponge disc — supplied: the manual gives it for the finishing pass on wall surfaces, and offers sponge discs in different hardnesses for internal and external lime-cement and gypsum plasters.
- DED77674 and DED77675 — ordered separately, and in dispute: the manual assigns those two codes to the opposite discs from the live product titles, in both its usage section and its accessory list, so order by the code printed on the disc being replaced rather than by function.
The plate itself is unaffected by that dispute, since it carries whichever disc is fitted. Where a slipping disc has been mistaken for a worn disc, replacing the plate is the cheaper first move; Renders World can confirm codes against current stock before dispatch.
Deciding Between a New Plate and a New Wear Disc
Ordering a mounting pad for render power float duty makes sense in some situations and not others, and the four below cover most of them.
- Discs will not hold on the face: the plate is the part that grips, so it is the component to change before buying another disc.
- The finish has fallen off but the disc looks sound: worth changing the plate, though the manual's own first answer to poor effectiveness is a worn disc — check that as well.
- A first kit is being priced: no purchase needed, since the plate is in the box with a new machine.
- A different make or model of float: the manual documents this platform alone, so confirm the spindle and fixing against that machine's own documentation first.
Confirm the code against the machine's model plate, then add the plate to the order beside the DED7767 plaster float it fits. The surfaces the machine works on come from the Renders World EPS adhesives basecoats range, with the decorative finish that follows drawn from the silicone render range.
FAQ — Fitment, What Ships in the Box, Care and Conditions
Which machine does the DED776701 plate fit?
The Dedra DED7767, and no other tool documented in the manual, locating on the spindle pin and tightened with a single screw. Other manufacturers' floats use different spindles, so check the model plate before ordering.
Do I need to buy one with a new machine?
No. The packing list includes the mounting disc along with the machine, a plastic disc with mesh, a sponge plate, screws, a screwdriver and carbon brushes, so a new machine is ready for floating work as delivered. This listing covers replacement and spare plates.
What shortens the life of the hook-and-loop face?
Residue left on it. The manual asks for the tool to be cleared of working residue after every session and for cleanliness to be maintained generally, which on this part means brushing the face before plaster fines have set into it.
Can the machine be used outdoors with this plate fitted?
Plan it for dry conditions: the machine is rated IP20 and the manual asks that damp be avoided, so exterior passes follow the weather window. Within a dry spell, the S2 15-minute duty cycle is the figure that shapes the session, with a cool-down between working periods.
