How to plaster a ceiling

GypCeil Classic Flush Plastered ceiling consists of steel branders fixed at 300mm centres in one direction onto which Gyproc RhinoBoard 6.4mm is fixed at right angles to the branders with printed side up using Gyproc RhinoBoard Sharp Point Screws 25mm spaced at 150mm centres.

 

Note: When plastering a ceiling all joints are to be covered with Gyproc RhinoTape (double over butt joints) and the ceiling plastered with a 3 - 6mm coat of RhinoLite / CreteStone.

You can buy Gyroc products at your local Builders Warehouse.

1. Use a tape measure to establish ceiling height; measure and mark the desired height in one corner of the room.

2. Using a spirit level, water level or a laser level, transfer the height mark (as per previous step) to all corners of the room.

5. Mark at 400mm centres.

6. Install suspension brackets using 2 x Gyproc RhinoBoard Sharp Point Screws 35mm per suspension bracket. Use the chalk line as a benchmark.

7. Measure and cut steel brandering to size and clip onto suspension brackets.

8. After installing the steel brandering, install ceiling insulation according to SANS 10400-XA for new buildings.

9. Measure and cut RhinoBoard 6.4mm to size. Install the board and fasten using Gyproc RhinoBoard Sharp Point Screws 25mm spaced at 150mm centres.

10. Install the next RhinoBoard 6.4mm. Repeat steps 9 until entire area is covered.

11. After boarding is complete, apply RhinoTape to all joints.

12. Apply Gyproc RhinoLite to all joints (pre-filling of joints) using a 150mm taping knife.

13. Apply RhinoLite to the entire surface using a 300mm steel trowel.

14. Leave the RhinoLite to set for a minimum of 40 minutes. Using a block brush lightly sprinkle water onto the RhinoLite surface. Use a sponge rubber float, and float the entire surface.

15. Using a 300mm steel trowel, scrap off the dead plaster (Fat).
