In the world of gypsum ceiling installation, a neat and smooth finish is the key to a perfect interior look.

What is the Function of Cornice or Compound in Gypsum Ceiling Installation?
Cornice is used in the finishing stage to cover the joints between gypsum boards, hide screws, and create a smooth ceiling surface that's ready to be painted. Cornice is also used in conjunction with joint tape to prevent cracks and ensure a long-lasting result. With proper use, cornice will provide a professional and aesthetic ceiling finish.
The Right Way to Use Cornice
Here are the general steps for using cornice during gypsum ceiling installation:
1. Prepare Materials and Tools
- Use high-quality cornice
- Prepare a clean container, water, and tools like spatulas, mixers, and scrapers
2. Mix Cornice with Water
- Mix according to the instructions on the packaging
- Stir until the mixture is smooth, not too thin or too thick
3. Apply to Gypsum Joints
- Use a scraper to level the cornice on the joints between boards
- Apply a thin and even layer
4. Apply Joint Tape
- When the cornice is still wet, apply joint tape to prevent hairline cracks
- Make sure it's applied evenly without bubbles
5. Apply Another Layer
- Add another layer of cornice on top of the joint tape
- Level the surface well
6. Wait for it to Dry and Sand
- After it's completely dry, sand it smoothly until it's even and ready to be painted
Tips for Using Cornice for Maximum Results
- Use cornice in moderation, don't apply it too thickly
- Mix in small amounts so it doesn't harden quickly
- Make sure the gypsum boards are clean from dust before application
