6mm Stop Bead With Mesh, PVC Render Bead 2.5m

This 6mm stop bead with mesh is the Bella Plast BP22 profile in its 6 mm, 2.5 m version: white PVC with a 6 mm render stop and a 100 mm glass-fibre wing. The wing goes into the reinforcing adhesive of an insulated wall, so the edge of the render is locked into the same layer as the wall mesh.

Four Reasons to Pick This 6mm Stop Bead With Mesh

• A 6 mm render stop. For a finishing coat up to 6 mm thick at the edge — twice the depth of the 3 mm bead.
• Wing included. Glass-fibre building mesh of at least 145 g/m², 100 mm wide, ready to bed in.
• Stops and divides. Bella Plast makes BP22 to end thin-coat render and to split one render from another where colour or grain changes.
• For EPS or mineral wool. It belongs to insulation systems on either board, finished in thin-coat render.

Specification

The Two 6 mm Stop Beads

Renders World sells a 6 mm stop bead with this wing and one without. They finish the same depth of render, so the question is only whether the edge is being reinforced:

Is 6 mm the Right Depth?

The render is closed off at the edge of the bead and may not stand higher than its render stop. So measure the finishing coat where it will meet the bead:

• up to 3 mm — the 3 mm stop bead with mesh;
• above 3 mm and up to 6 mm — this 6mm stop bead with mesh;
• thicker coats — the 10 mm or 15 mm stop bead, which come without a wing.

Where the beads run on the elevation is set by the façade designer. All five sizes are compared in the render stop bead range.

Bedding It Into the Base Coat

1. Trowel an adhesive made for glass mesh on EPS or wool evenly over the boards, keeping it to 2.5 mm or less.
2. Lay the bead and press its wing into that adhesive.
3. In the same pass, run the wall's reinforcing mesh over the wing with a 10 cm lap, so the two meshes share one layer.
4. Let it dry, prime, then apply the render and close it off at the bead's edge.

The wall mesh also has to run unbroken behind the bead. Expanding polyurethane foam is not an approved fixing. For the lap, Ceresit CT 325 fibreglass mesh is in stock. The stop bead fitting guide, render detailing at windows and doors and the guide to which render bead for which detail show where the bead meets other profiles.

Handling, Cutting and Storage

• Cutting — plastic shears or a fine-tooth saw; wear gloves and goggles, as the wing is glass fibre.
• Heat — 52 °C on the bead's outer face is the working limit, and it is not made for surfaces above +60 °C.
• Solvents — keep acetone and benzene away; organic solvents attack the PVC, while ordinary building materials do not react with it.
• Storage — dry, cool, laid flat, 0 to 50 °C, at most 30 layers high.

Counting Lengths

Each length is 2.5 m. Take every edge on its own and round up:

• a 5 m edge needs 5 ÷ 2.5 = 2 lengths;
• an 8 m edge needs 8 ÷ 2.5 = 3.2, so four;
• a window gives three edges — the head and two reveals.

Because the maker allows ±5 % on length, check the last piece of a run against the gap before cutting.

Before You Order

• Coat over 6 mm at the edge? Move to the 10 mm or 15 mm bead.
• No mesh layer at that edge? The plain 6 mm bead is the simpler choice.
• Mesh for the lap. Add reinforcing mesh to the same basket as the 6mm stop bead with mesh.
