Exploring Plastering Techniques

There are several plastering techniques, each suitable for different needs and preferences:

  • Wet Plastering: Known for its durability and soundproofing capabilities, though it requires longer drying times and can be prone to cracking.
  • Dry Plastering: Involves attaching plasterboard to walls, followed by a plaster coat, which is quicker and allows for added insulation.
  • Skim Plastering: Focuses on applying a final, smooth coat to walls, perfect for minor repairs and paint preparation.
  • Rendering: Used for exterior walls, involving multiple plaster coats to achieve a smooth and protective finish.

Factors Affecting Plastering Costs

Several factors can influence the cost of plastering a room:

  • Type of Plastering: Different methods involve varying degrees of labor and material costs.
  • Room Size: Larger areas generally cost more due to increased material and labor.
  • Access Difficulty: Hard-to-reach areas may increase the time and cost of plastering.
  • Time and Labor: Longer projects will naturally incur higher labor costs.
  • Desired Finish: High-quality finishes and additional features like painting or decorative touches can add to the cost.

Key Takeaways for Successful Plastering

Plastering can repair damages, smooth out surfaces, and add significant insulation to your home. While DIY plastering is possible, the complexity and potential for mess make it a task generally best left to professionals.


Whether you’re repairing a few cracks or plastering entire rooms, understanding the types of plastering available and what factors affect the cost can help you budget more effectively. Always consider the scope of your project and seek professional advice to achieve the best results.
