General Introduction to Plaster Stop Beads and uPVC Plaster Stop Beads
Finishing beads are construction accessories designed to make finishing works faster, more accurate and visually refined while reducing installation errors. They can be manufactured from various materials, including galvanized steel, stainless steel and uPVC.
uPVC finishing beads are engineered uPVC profiles available in various designs for building finishing works, including plastering, rendering, tiling and skim-coat application.
Plaster stop beads are manufactured from materials such as galvanized steel, stainless steel, uPVC or aluminium. They are installed at plaster and render terminations to create straight, flat and uniform finishing edges while helping reduce installation errors, cracking and edge chipping.
uPVC Plaster Stop Beads are manufactured from uPVC in L-shaped or fish-scale configurations. They are used at plaster and render terminations, including wall edges, wall bases and the exposed edges of external walls. The beads create straight, accurately defined edges, accelerate installation and help reduce chipping, cracking and workmanship errors while providing a refined and safer finish.

General Introduction to PVC, uPVC and Engineered uPVC
uPVC Plaster Stop Beads are manufactured from uPVC, also known as PVC-U. The full name of uPVC is “Unplasticized Polyvinyl Chloride”. It is a rigid form of PVC that contains no plasticizers. This rigidity gives uPVC enhanced mechanical, physical and chemical properties compared with conventional flexible PVC.
HAN develops engineered uPVC from a uPVC base formulation and adds specific mechanical, physical and chemical performance characteristics to suit different construction applications.
HAN uPVC Plaster Stop Beads are made from engineered uPVC to provide enhanced rigidity, toughness, elasticity, surface gloss, colour stability and chemical resistance, making them suitable for plastering and rendering requirements.
HAN uPVC Plaster Stop Beads are safe for installers and building users when used as intended.
The service life of HAN uPVC Plaster Stop Beads is compatible with that of plastered and rendered finishes under normal ambient and climatic conditions.

Selecting and Using uPVC Plaster Stop Beads for Plastering and Rendering Works
To achieve the best technical, economic and aesthetic results when using uPVC Plaster Stop Beads at the terminations and exposed edges of plastered or rendered areas, customers should consider the following:
| No. | Item | Key considerations | What to avoid |
| 1 | Product code | Identify the correct HAN product code when the construction specification has already been established. | |
| 2 | Design |
Select the appropriate design for the application: L-shaped or fish-scale profile. |
Do not select a lower-cost design without considering installation requirements, performance and finished appearance. |
| 3 | Size | The plaster or render thickness must be compatible with the bead height. The finished layer should be approximately 1 mm thicker than the bead height. | |
| 4 | Standard lengths | For small quantities, use HAN’s standard lengths of 2, 2.5 or 3 metres. For high-volume projects, custom-cut lengths can reduce offcuts, material waste and unnecessary costs. | Avoid ordering unsuitable lengths that create excessive offcuts, material waste and additional installation costs. |
| 5 | Quantity | Determine the required quantities and specifications accurately and include a reasonable allowance for cutting waste. | |
| 6 | Order lead time | Make sure the products are available in the site warehouse before installation begins to prevent delays to the construction programme. | Avoid placing orders too close to the installation date, as this may affect the construction schedule. |
| 7 | HAN product identification | Purchase from an authorized distributor or directly from HAN. The packaging should clearly display HAN’s product code, address and telephone number. | Products in packaging that does not clearly display HAN’s factory information may not be genuine HAN products. |
| 8 | Responsible personnel | Personnel with suitable technical knowledge and experience should consult directly with HAN’s technical advisory team before making purchasing decisions. | |
| 9 | Installation method | Follow HAN’s installation instructions: fully bed the bead in mortar, apply a suitable plaster or render thickness, set the profile at the correct line and level, and secure it firmly to achieve the best performance and appearance. For product codes supplied with temporary protective film, remove the film at the appropriate time to preserve the finished surface. | |
| 10 | Storage method | Follow the recommended transport and storage procedures to maintain product quality before installation. |
To achieve a high-quality finish, remove the temporary protective film at the appropriate time after installation, cleaning and completion of all related works. This helps protect the bead surface until the finished area is ready for use.
Correct Transport and Storage of HAN uPVC Finishing Beads
Transport recommendations for HAN uPVC Finishing Beads:
- Do not drag cartons along the ground or throw them from a height.
- Do not leave cartons standing vertically or leaning for extended periods.
- Use a vehicle with a flat loading platform and a covered cargo area or tarpaulin to protect the products from rain.
- When transporting different bead types in the same vehicle, place longer and heavier cartons underneath and shorter and lighter cartons on top.
- Do not place heavy or sharp objects on the cartons. Make sure the cartons are not bent, distorted or punctured during transport.
- Handle cartons correctly during loading and unloading to prevent tearing, bending or deformation.
Storage recommendations for HAN uPVC Finishing Beads:
- Store indoors on pallets in a dry, cool and well-ventilated area. Protect the products from direct sunlight, water, soil, mud, moisture, mould and high temperatures.
- Do not store cartons vertically. Individual beads should not be stored upright or leaning for extended periods, as this may cause them to bend.
- When the products are not in use, clean and repack them in their cartons to protect them from dust and preserve their colour, smoothness and gloss.
- Do not turn cartons upside down. Keep them in the orientation indicated by the arrows printed on the packaging.
Quality Standards for HAN uPVC Plaster Stop Beads
HAN uPVC Plaster Stop Beads comply with the following relevant standards and requirements:
- ASTM D638, ASTM D790, ASTM D1525 and ASTM D648.
- Relevant requirements of the current Vietnamese construction standards (TCVN).
- High-quality uPVC finishing beads should meet the criteria below.
 |
 |
| The mechanical, physical and chemical properties of the uPVC must meet installation, mortar-bonding and in-service performance requirements. | The finished bead must be flat, straight, uniform and dimensionally accurate. |
In building finishing works, plastering and rendering are among the most important activities affecting the overall quality and appearance of a project.
Finishing plaster terminations and exposed edges requires a high degree of accuracy and professional workmanship to achieve straight, even, precise and visually refined results.
When plaster termination edges are formed using conventional methods without uPVC Plaster Stop Beads, the following problems may occur:
- Termination edges may be uneven, misaligned, insufficiently flat or poorly finished.
- Exposed edges may be excessively sharp, creating a potential safety risk. They are also more susceptible to chipping during use, resulting in higher maintenance and repair costs.
- Installation may be slow and difficult, particularly when numerous termination edges are required, while the achievable finish may be aesthetically limited.
- Workers must maintain a high level of concentration, increasing fatigue and pressure and potentially affecting the construction schedule.
Using HAN uPVC Plaster Stop Beads provides the following benefits:
- Creates straight, flat, uniform and accurately defined plaster termination edges because the bead profiles are manufactured to consistent dimensions.
- Provides purpose-designed edges that are not excessively sharp, making them safer and more suitable for use.
- Helps protect finished edges against impact and reduces the risk of chipping during use.
- Simplifies the finishing of plaster terminations and exposed edges, accelerates installation and reduces labour costs.
To use HAN uPVC Plaster Stop Beads correctly at plaster and render termination edges, customers should observe the following guidelines:
- Select the appropriate stop bead profile for the application:
- L-shaped profile PRS0150: suitable for junctions and plaster termination edges.
- Fish-scale profile PBC0150: suitable for dividing large external rendered wall surfaces into smaller sections, helping reduce cracking and slow rainwater runoff to provide better protection for the wall surface.
- Select a bead size suitable for the plaster or render thickness. The bead height should be at least 1 mm less than the thickness of the finished plaster layer.
- Choose a suitable colour according to the design and aesthetic requirements. The three standard colours are white, red and grey.
- For areas subject to frequent contact or impact, consider using a gloss-finished profile for easier cleaning.
- Level and clean the substrate thoroughly before plastering or rendering. Dampen the surface to improve adhesion. At critical locations, reinforcement mesh may be fixed to the substrate to improve bonding and help reduce shrinkage cracking in the plaster layer and at material junctions.
- Prepare suitable setting-out and levelling tools. A laser level can accelerate installation by simultaneously aligning multiple vertical and horizontal edges within the same area.
- Use a specialized cutting tool to produce clean, accurate joints. Pay particular attention to cutting at 90° intersections to achieve a neat and visually consistent finish.
- Secure the bead firmly using mortar or screws. Do not drive screws through the exposed decorative face of the bead.
- Remove excess plaster or render promptly to prevent it from adhering to the exposed bead surface.
- Carry out final cleaning at the appropriate time and remove the protective film when suitable to preserve the quality and appearance of the bead.
- Store unused beads properly in accordance with HAN’s storage instructions.
