Description
This 6mm stop bead with mesh is a Bella Plast BP22 profile: white PVC with a 6 mm edge and a glass-fibre mesh wing, sold in 2.5 m lengths. The mesh wing is what sets it apart from the plain 6 mm bead in the same range, and it is there so the bead can be bedded into the reinforcing layer of an insulated wall. Both sit in the Renders World stop bead range.
What the 6mm Stop Bead With Mesh Is
BP22 is the Bella Plast code for PVC stop beads with mesh, made to finish thin-coat render on an insulated facade and to divide one render from another where the colour or the grain changes. The render is ruled off against the edge of the profile.
- Edge height: 6 mm, the second of the four BP22 sizes (3, 6, 10 and 15 mm).
- Length: 2500 mm, the BP22 L250 version; the 2000 mm length is not in the range.
- Mesh wing: glass-fibre building mesh of at least 145 g/m², 100 mm wide.
The body is rigid PVC with plasticisers added for mechanical resistance and UV stabilisers against sunlight.
The listing names no maker. Its handle carries L250, the Bella Plast length code, it shows the same photograph as the 3 mm stop bead with mesh, whose earlier shop address carried the full BP22 code, and its size, length and mesh wing match the BP22 L250 6 mm. The figures here come from the Bella Plast data sheet for that profile.
6 mm With Mesh or Without
The range holds two 6 mm stop beads, and they are easy to confuse in a basket:
| Bead | Edge height | Mesh wing | What the listing gives |
|---|---|---|---|
| This bead | 6 mm | Yes, 100 mm | BP22 data sheet |
| 6 mm stop bead without mesh | 6 mm | No | Size, length and photograph only |
The mesh wing is bedded into the reinforcing adhesive together with the facade mesh, so this bead belongs to a wall that is being reinforced as the beads go on. The plain bead has nothing to bed into that layer.
Which Coat the 6 mm Edge Suits
The size follows from the fitting instructions:
- The maker's rule: the render is finished at the edge of the bead and must not be thicker than the height of the render stop on the profile.
- For this bead: the 6mm stop bead with mesh suits a finishing coat of up to 6 mm at that edge.
For a coat of 3 mm or less there is the 3 mm stop bead with mesh; the 10 mm and 15 mm stop beads in the range carry no wing.
Where the beads run on the facade is a decision for its designer; the maker states that BP22 is fitted on the outside of the building, in insulation systems on EPS or mineral wool boards finished with thin-coat render.
How Bella Plast Says It Is Fitted
- Adhesive: spread an adhesive intended for glass mesh, EPS or wool evenly over the boards with a trowel, no thicker than 2.5 mm.
- Bead mesh: press the bead's own mesh into it.
- System mesh: straight away cover it with the facade reinforcing mesh lapped 10 cm, in the same gluing operation, so both meshes sit in one layer of adhesive.
Once the adhesive is dry and primed, the render goes on evenly and is finished at the edge of the bead. A continuous layer of the system facade mesh must also run beneath the bead. Polyurethane foam must not be used to fix it. Cut it with shears for plastics or a fine-tooth saw, wearing gloves and eye protection because of the glass mesh. A facade mesh to lap over the wing is in the range as Ceresit CT 325 fibreglass mesh, and the stop bead fitting guide, render detailing at windows and doors and the guide to which render bead for which detail cover the details around it.
Heat, Solvents and Storage
- Surface temperature in use: no higher than 52 °C on the outer surface of the bead; the maker also states it is not resistant above +60 °C.
- Chemicals: it does not react with solid building materials and resists ageing, but organic solvents such as acetone and benzene attack it.
- Storage and transport: dry, cool, flat, between 0 °C and 50 °C, no more than 30 layers high for the 6 mm size.
Bella Plast packs 25 pieces to a carton; the 6mm stop bead with mesh is sold here as single 2.5 m lengths.
How Many Lengths an Edge Takes
Divide each edge where the render stops by 2.5 m and round up:
- a 5 m edge takes 5 ÷ 2.5 = 2 lengths;
- an 8 m edge takes 8 ÷ 2.5 = 3.2, so four lengths;
- the head and both sides of an opening count as three separate edges.
The maker's length tolerance is ±5 %, so measure a length before cutting the last piece of a run.
What the Data Sheet Does Not Give
Three things are not settled by the listing or the Bella Plast sheet:
- Profile dimensions: no flange width or hole size as figures.
- UK paperwork: the sheet refers to Polish national documents, not to a UK certificate.
- Maker on the listing: the listing does not print the maker's name.
If a specification needs any of these settled, ring 023 8200 2442 before ordering.

FAQ
Is this the 6 mm bead with mesh or without?
With mesh: a 100 mm glass-fibre wing runs along the profile. The plain 6 mm bead is a separate listing in the same range.
What render thickness is it for?
A finishing coat up to 6 mm thick at the bead; the maker's rule is that the render must not rise above the bead's edge.
How far does the facade mesh lap over a 6mm stop bead with mesh?
10 cm, bedded in the same layer of adhesive as the bead's own mesh, with the system mesh also running continuously under the bead.
Can it be fixed with expanding foam?
No. Bella Plast does not allow polyurethane foam for fixing BP22.
