Introduction
Finishing wall corners is one of the most delicate stages of plastering. Without proper reinforcement, corners are prone to cracks, chipping, and mechanical damage. The solution is aluminium corner beads for gypsum plaster, which ensure both durability and a clean, aesthetic finish.
1. What are aluminium corner beads?
They are profiled aluminium elements designed to be embedded in plaster. Their purpose is to:
-
reinforce wall and ceiling corners,
-
protect against mechanical damage,
-
make plaster application easier and more precise,
-
create straight, clean, and aesthetic edges.
2. Why aluminium?
-
Lightweight and strong – aluminium combines low weight with high durability.
-
Corrosion resistant – it does not rust, which is crucial in humid rooms.
-
Easy to cut and install – can be adjusted quickly to any wall height.
-
Precision finish – ensures perfectly straight corner lines.
3. Installation step by step
-
Cut the corner bead to the required length.
-
Apply a strip of plaster along the corner.
-
Press the bead firmly into the fresh plaster, checking alignment.
-
Cover and smooth the surface with gypsum plaster.
4. Common mistakes
-
Too little plaster → the bead does not adhere properly.
-
No level check → crooked corners.
-
Using unprotected steel profiles → corrosion and damage after a few years.
Conclusion
Aluminium corner beads for gypsum plaster are a small investment that greatly improves durability, aesthetics, and resistance to damage. They guarantee clean, straight corners and long-lasting walls.
