Introduction to PVC Corner Beads
PVC corner beads, also known as indoor corner beads, wall protection corners, architectural corner beads, etc. This product is a new type of building material specially designed for the difficult construction of wall corners, door edges, and window corners. It is characterized by unique features such as environmental protection, weather resistance, and anti-aging. Its strength and toughness have allowed it to be confidently used as a replacement for traditional materials such as steel, wood, and aluminum. The current wall corner construction process in China has followed traditional methods for decades, resulting in low efficiency and cumbersome engineering. Additionally, walls are very vulnerable to damage during use; on one hand, this is due to the high frequency of contact at corners, and on the other hand, it is due to inadequate sturdiness of the corners. Damaged corners often lack specialized repair personnel, leading to a decline in construction quality. Especially at door and window corners, residential buildings typically use edging treatments, but this approach wastes a large amount of wood and incurs significant costs, causing considerable pollution. Currently, internationally recognized PVC corner beads are manufactured from high-strength polyvinyl chloride material, which is environmentally friendly and corrosion-resistant. They exhibit shock resistance, anti-aging properties, and good weather resistance. Their widespread use can effectively address long-standing quality issues in construction, such as corners not being straight, unattractive appearances, and easy damage to wall corners.
Important Recommendations
1. According to research in Japan, the conclusion is: A project originally scheduled for 20 months was shortened by 3 months after adopting PVC corner beads.
2. It is recommended to use PVC architectural corner beads for professional protection in areas with concentrated stress or high contact frequency, such as inner and outer wall corners, doors, and windows.
3. According to domestic building height regulations, the general length of this product is 250 cm. If the site dimensions differ, it can be cut or extended; however, the joints must be neat.
4. The product can be used vertically or horizontally.
5. For larger corners and window sills or other areas needing special attention, it is recommended to use a two-wing widened type or PVC corner beads with mesh cloth.
Product Features
1. Made from PVC and additives, flame-retardant, environmentally friendly, and non-polluting;
2. Easy to operate during construction;
3. Wide range of applications, including balconies, stairs, indoor and outdoor wall corners, window sills, gypsum board connections, arched doors and windows, etc.;
4. The product has high strength and can bond well with putty; corner beads are fully integrated with the wall;
5. Replaces metal, wooden, acrylic, and other material corner beads, reducing costs and enabling widespread promotion;
6. Completely changes the traditional manual construction method of cement-sand corner, marking an important transformation in the construction field.
Main Advantages of the Product
1. Straight and aesthetically pleasing;
2. Impact-resistant and durable, effectively solving the recurring issues of damage, cracks, and detachment at wall corners;
3. Changes the traditional cumbersome construction process, reduces labor intensity, increases efficiency by 3-5 times, shortens construction time, and lowers project costs.
Construction Points
1. First, check the verticality of the wall corner and the flatness of the wall surface. If the discrepancy is too large, remove any protrusions or uneven depressions.
2. Prepare a special cement paste: Mix white cement and wood glue in a ratio of about 3:1, then add an appropriate amount of old powder and 801 glue, mixing well.
3. Use the special cement paste to smooth the wall corner and wall surface, keeping the paste at an appropriate thickness.
4. Visually inspect the straightness and toughness of the architectural corner beads; if there are professional limitations, we recommend choosing a brand with certain standards.
5. Press the corner bead tightly against the wall corner, allowing the paste to ooze out from the perforations; for added firmness, we suggest using nails to secure it. Subsequently, gently smooth the cement paste that has oozed out from the perforations.
6. After it dries slightly, apply a layer of specialized paste and smooth it out.
