How To Repair Mortar Joints in Brickwork

NP Digital

Key Takeaways:

  • Granular Finish for Realism: Unlike standard sealants, Repair Express Cement contains a granular texture. This ensures the repair blends in with the original mortar rather than looking like a smooth plastic bead.
  • Prep the Joint: You must remove any loose or crumbling mortar before starting. If you apply the product over loose debris, the repair will eventually fall out as the old mortar continues to fail.
  • Paintable Results: Once fully cured, this product is paintable. This is useful if your brickwork or mortar has been previously painted or if you want to match a specific colour.
  • Indoor and Outdoor Use: This cement is highly weather-resistant. It is suitable for repairing exterior brick walls or interior masonry features like fireplaces.

Professional Mortar Repair for Brickwork

Damaged or crumbling mortar joints can lead to water ingress and structural issues over time. Soudal Repair Express Cement provides an easy solution for filling cracks and joints in masonry. It comes in a standard cartridge, making it much faster to apply than traditional mortar mixes.

Step-by-Step Application Instructions

  1. Prepare the Joint: Use a wire brush or a small chisel to remove loose mortar. The joint should be clean and solid.
  2. Clean the Surface: Blow out any remaining dust or grit. A clean surface is essential for the cement to bond to the bricks.
  3. Prepare the Cartridge: Cut the tip of the cartridge and screw on the nozzle. Cut the nozzle to match the width of the mortar joint.
  4. Apply the Product: Place the cartridge into a caulking gun. Apply the cement directly into the joint, ensuring you fill the gap completely.
  5. Smoothen the Joint: Use a damp pointing tool or your finger to press the cement into the joint and smoothen the surface.
  6. Clean Up: Wipe away any excess product from the face of the bricks using a damp cloth before it dries.
  7. Curing: Allow the product to dry. It will harden to a stone-like consistency that matches the surrounding mortar.
