REMOVING RENDER FROM BRICKWORK
REPAIR AND CLEAN

Removing render from brick and stone surfaces can be a challenging yet necessary task, especially if the render is damaged, has deteriorated, or is not suited to the underlying materials. Render can trap moisture, lead to damp issues, or simply become unsightly over time (https://www.remedialbrickwork.co.uk/removing-render-from-brickwork.html).

​Understanding the process of render removal, the tools required, and the precautions to take is essential for achieving a clean and effective result without damaging the underlying masonry. 

SOLUTION.

Here’s a comprehensive guide on how to remove render from brick and stonework:

1. Assess the Condition of the Render
  • Inspect the Render: Begin by examining the render for signs of damage, cracking, or peeling. Identifying the extent of the issues will help determine the best approach for removal.
  • Check the Underlying Material: Ensure the condition of the brick or stone underneath is satisfactory. If the masonry is already compromised, you may want to consult a professional before proceeding.

2. Gather Your Tools and Materials
Prepare the following tools and materials before starting the render removal process:
Tools:
  • Hammer and chisel
  • Angle grinder with a masonry blade (for larger areas)
  • Stiff-bristle brush
  • Scraper or putty knife
  • Safety goggles and gloves
  • Dust mask or respirator
  • Bucket or container for debris
  • Tarps or plastic sheeting (to protect surrounding areas)
Materials:
  • Water (for wet removal)
  • Chemical render remover (optional, for tough cases)

3. Protect Surrounding Areas
  • Use Drop Cloths: Lay down tarps or plastic sheeting to protect the surrounding areas from debris and dust generated during the removal process.
  • Safety Gear: Ensure you’re wearing safety goggles, gloves, and a dust mask or respirator to protect yourself from dust and debris.
4. Choose a Removal Method
There are two primary methods for removing render: mechanical and chemical. The choice of method will depend on the thickness of the render, the condition of the underlying masonry, and personal preference:

Mechanical Removal:
  • Chisel Method: For small areas or thin layers of render, use a hammer and chisel to chip away the render carefully. Start at the edges and work your way inward. Be cautious not to damage the underlying brick or stone.
  • Angle Grinder Method: For larger areas, an angle grinder fitted with a masonry blade can speed up the process. Hold the grinder at a slight angle and carefully cut through the render, avoiding excessive pressure to prevent damage to the masonry.
Wet Removal:
  • Soaking the Render: If the render is thick, consider wetting it down with water. This can help soften the material, making it easier to remove with a scraper or chisel.
  • Use a Scraper: After soaking, use a scraper or putty knife to lift and remove the softened render from the brick or stone surface.
Chemical Removal:
5. Clean the Surface
  • Remove Debris: Once the render is removed, use a stiff-bristle brush to clean off any remaining debris, dust, or loose particles from the brick or stone surface.
  • Rinse Thoroughly: If you used water or a chemical remover, rinse the surface thoroughly with clean water to remove any residues. This will help prevent future damp issues.

6. Inspect the Underlying Brick or Stonework
  • Check for Damage: After render removal, inspect the underlying masonry for any damage, such as cracks or spalling. Address any issues promptly to maintain the structural integrity of your brick or stonework.
  • Repair as Needed: If the brick or stone surface has been damaged during the render removal process, consider repointing or replacing affected areas as necessary.

7. Apply Protective Measures
  • Consider Re-rendering: If the render was removed to replace it, consider applying a breathable render suitable for brick and stone surfaces to protect against future weathering and moisture infiltration.
  • Seal the Surface: After ensuring the brick or stone surface is in good condition, you may want to apply a breathable, water-repellent sealant to enhance protection (https://remedial.shop/products/remedial-works-masonry-sealer).

PREVENTION:

CONCLUSION:

Removing render from brick and stonework can be a labour-intensive process, but with the right tools, techniques, and precautions, it can be done effectively. By following these steps, you can restore the natural beauty of your masonry and prevent potential moisture issues associated with poorly applied or deteriorating render.

If you encounter significant difficulties or structural concerns, consider consulting a masonry professional for expert advice and assistance. Remedial Repair can advise on this (https://www.remedialrepair.co.uk/contact.html).
