How to Prepare Walls and Ceilings for Plastering
Proper wall and ceiling preparation is critical for a smooth, long-lasting plaster finish. Without correct preparation, plaster may crack, peel, or fail to adhere. Professionals follow a step-by-step process to ensure flawless results.
Step 1: Inspect Walls and Ceilings
Check for cracks, water damage, hollow areas, or previous repairs. Identify surfaces that need reinforcement or replacement.

Step 2: Remove Loose or Damaged Material
Any flaking plaster, wallpaper, or debris should be removed before plastering. This ensures proper adhesion of the new plaster layer.
Step 3: Repair Cracks and Holes
- Small cracks: Use jointing tape and filler.
- Large cracks or damaged boards: May require partial reboarding.
- Water-damaged areas: See how to repair water damage before plastering.
Step 4: Sand and Clean Surfaces
Sanding rough spots creates a smooth base. Clean dust and debris thoroughly to ensure plaster sticks properly.
Step 5: Apply a Bonding Agent
On older walls or smooth surfaces, a professional may use a primer or bonding agent to improve plaster adhesion.
Step 6: Reinforce Weak Areas
Hollow spots, loose boards, or previously patched areas may require reinforcement. Experts use mesh or backing boards to prevent cracks.
