Yes, you can install natural stone wall cladding directly over existing brickwork, provided the brick wall is structurally sound, clean, and properly prepared. You do not necessarily need to demolish the old wall, making it a highly cost-effective way to modernize your home’s facade.

Essential Steps for Cladding Over Bricks

  1. Check Structural Integrity: Ensure the existing brick wall can handle the additional weight of the natural stone (which can be up to 80kg per square meter).
  2. Clean the Surface: Remove all dirt, loose mortar, and painted surfaces. Paint must be ground off to expose the raw brick for proper adhesion.
  3. Apply Primer/Scratch Coat: For maximum grip, apply a masonry primer or a cement scratch coat over the bricks.
  4. Use Premium Adhesive: Always use a high-grade, polymer-modified stone adhesive specifically rated for heavy exterior natural stone.
