CORNER BEADS

Nose depth, not price, decides whether a corner bead vanishes into the finish or draws a bright line down the elevation. At the shallow end of the range, the no-mesh profile earns its place on the corners a mesh-wing bead cannot physically reach.

Which UK Corners Take a 6mm No-Mesh Bead

The 6mm PVC render corner bead no mesh suits shallow render corners and confined reveals, and Renders World lists it at £3.00 per 2.5 m length as fetched in September 2026, supplied as single lengths rather than packs. It sits inside the wider PVC, aluminium and steel corner profile range, and it is the profile to reach for when arm space rather than strength is the constraint.

What separates it from the mesh-wing profiles is the fixing mechanism. Render squeezes through the perforated arms and grips the bead mechanically, so there is no fibreglass wing waiting on a reinforced basecoat to bury it. That is why the profile keeps appearing in two situations that have nothing else in common.

• Shallow traditional coats: lime, fine sand-and-cement and light one-coat finishes, where the shallowest nose in the range is the one that finishes flush with the topcoat.
• Narrow reveals and tight internal angles: details with no flat run to press a mesh wing into, on elevations that are otherwise built deeper.
• Heritage and conservation corners: period work where the specifier is holding the build-up down rather than adding to it, and proportion at the arris matters.

Why Trade Specifiers Fit the No-Mesh Profile at Shallow Depths

Specification here is a geometry decision before it is a materials decision. The bead sets the finished plane at the arris, so the depth chosen is the depth the render then has to reach across the whole corner zone.

• Flush arris on a thin coat: the shallowest nose in the no-mesh range reads as part of the finish rather than as a trim line under raking light.
• Mechanical key without a mesh layer: render locks through the arm perforations, so the corner does not depend on a fibreglass wing bonding into a basecoat that a shallow system may not have.
• Single-stage corner detailing: bed and over-render in one continuous operation, with no separate mesh layup pass to programme around.
• Rigid profile holds its line: the bead keeps whatever line the installer gives it over the full length, which is what makes a long level worth using at bedding.
• Priced as a single length: at £3.00 per 2.5 m piece in September 2026, buying the right depth rather than the nearest one to hand costs almost nothing.

Corner Bead Dimensions Confirmed, and the Specs We Do Not Quote

No manufacturer datasheet for this profile exists in the Renders World document set, and a live search this session returned nothing product-specific. Nothing read this session gives a render-depth band, an arm width or a standard reference for the 6mm PVC render corner bead no mesh, so none is published below.

The practical instruction is a short one. Measure the finished render depth at the corner and match the nose to that measurement on site, rather than working back from a published band. On a profile costing a few pounds a length, a straight edge and a tape at three heights settles the specification more reliably than any table.

How to Fit the 6mm Bead in Reveals and Tight Returns

Back-buttering is the difference between a clean reveal and a fight with the geometry. Load both arm faces with render or adhesive mortar before the bead goes near the wall, then press it home in one movement, because a narrow reveal rarely leaves room to butter the substrate and land the bead on a wet face afterwards.

1. Butter both arms with a continuous bed rather than dabs, so there are no hollows behind the arms once the corner is over-rendered.
2. Press the arris square to the corner until render extrudes through every perforation along both arms.
3. Check the line with a long level while the bed is still open, since the rigid profile keeps whatever line it is set to.
4. Cut with a fine-tooth hacksaw or bead scissors; tin snips crush a shallow nose and take the arris out of square at the joint.
5. Butt cut ends tightly and render across each joint continuously, so the finished arris reads as one uninterrupted line.

For head and base terminations, and the order of work where corner, stop and bellcast profiles meet on the same elevation, the step-by-step corner bead installation guide carries the full sequence.

Bedding Conditions That Keep a Shallow Corner Tight

Fix the bead and render the corner in the same session wherever the programme allows. A shallow coat carries less material around the arms to absorb early movement, so bedding mortar and surrounding render perform best when they cure as one mass rather than a day apart.

Dust the corner down and damp high-suction masonry before bedding. A dry wall draws water out of the bedding mortar faster than the mortar gains strength, and on a shallow profile there is little else holding the arms in place.

Substrate condition drives the rest of the detail. Where the corner forms part of a water-management detail, or lands at a window or door opening, the right profile changes with the location, and the guide to render detailing at windows and doors works through each junction in turn.

Choosing Between the Three No-Mesh Corner Bead Depths

All three no-mesh depths do one job, which is a flush arris keyed into the render by perforated arms, so the decision is nose depth against finished coat depth. Renders World holds the three as separate lines priced within pennies of one another, which means matching the depth properly carries almost no cost penalty.

Depth bands for each profile are left out deliberately, because no datasheet for this range was readable this session. Step up a depth where a dubbing-out coat or a retained existing render will push the build-up deeper at the arris than the finish coat alone suggests.

Order the Right No-Mesh Depth for Your Render

Take off by measured corner length rather than by storey count. Add the vertical corners across each elevation, divide by the piece length and round up: 18 m of corner ÷ 2.5 m per length = 7.2, so eight lengths, and 8 × £3.00 = £24.00 at September 2026 pricing. Set the cutting allowance against the number of short returns on the job rather than a flat percentage.

• Shallow coats and confined reveals: this depth is the straight-through specification, fixed and over-rendered in one pass.
• Deeper or dubbed-out build-ups: step up to the 10 mm or 15 mm profile so the nose is buried rather than proud.
• Reinforced-basecoat thin-coat systems: a no-mesh profile brings no wings of its own, so field reinforcement is carried round the corner separately — Ceresit's sheet for CT 325 reinforcing mesh sets strip overlaps at about 10 cm within Ceresit ETICS build-ups.
• Delivery: Renders World despatches small parcels up to 25 kg on a next-day courier service, with all deliveries made curbside, under a policy that applies site-wide rather than to this line alone.

FAQ — Fitting and Ordering the 6mm No-Mesh Corner Bead

How many lengths does a two-storey corner take?

Measure the vertical run at each external corner rather than assuming a storey height, then divide by 2.5 m and round up per corner, since part-lengths rarely transfer usefully between corners. Adding the corners first and dividing once understates the count, because every corner ends in an offcut.

Does a no-mesh bead need separate mesh at the corner?

The perforated arms on the 6mm PVC render corner bead no mesh key mechanically into a traditional coat, and on thick-coat and lime work a separate corner mesh is not normally specified. Where the system uses a reinforced basecoat, the field reinforcement carries round the corner as its own layer, or a mesh-wing profile takes that role instead.

When is the 10mm profile the better buy?

Once the finished coat at the arris is deeper than the shallowest nose can sit within, the deeper profile stops the bead reading proud. Ten pence separates the two lines, so the deciding factor is the measurement at the wall rather than the price difference.

Can this profile be used at a plinth or a sill return?

Horizontal terminations where water tracks across the face want a drip or bellcast profile, which sheds water clear rather than holding it against the substrate. Profile selection by detail type is set out in the bead selection guide by render detail.
