8 Crucial Steps for Proper Internal Plastering Preparation

  1. Surface Cleaning: Begin by thoroughly cleaning the surface to remove dust, dirt, grease, or any loose particles. This can be achieved using a brush, vacuum cleaner, or a damp cloth.
  2. Repairing Cracks and Holes: Identify and repair any cracks or holes in the surface using a suitable filler or patching compound. Smooth out the repaired areas to create a seamless surface.
  3. Priming the Surface: Applying a primer is crucial for promoting proper adhesion between the surface and the plaster. Choose a primer suitable for your specific surface type and follow the manufacturer’s instructions.
  4. Applying a Base Coat: The base coat acts as a bonding layer between the surface and the final plastering. It helps create a strong foundation and improves the overall durability of the plaster.
  5. Installing Reinforcement: In areas prone to stress or movement, such as corners or joints, it is advisable to incorporate reinforcement materials, such as mesh or tape, to minimize the risk of cracking.
  6. Applying the Final Coat: Once the base coat is dry, it’s time to apply the final coat of plaster. Ensure an even and consistent application, taking care to achieve the desired thickness and texture.
  7. Curing and Drying: Allow sufficient time for the plaster to cure and dry according to the manufacturer’s guidelines. This step is crucial to ensure the plaster sets properly and attains its maximum strength.
  8. Surface Finishing: After the plaster has dried, you can proceed with surface finishing techniques such as sanding, polishing, or texturing to achieve the desired aesthetic appeal.
