Can I install Brickwebb over a cinder block wall?

Yes, installing Brickwebb on a cinderblock wall is easy to do.

Installing Brickwebb on Cinder Blocks

Materials Needed:

  • Modified thin-set adhesive (such as a polymer-fortified thin-set)
  • 3/8” notched trowel
  • Brickwebb sheets
  • Grout (Type S mortar or sanded tile grout)
  • Grout bag or tile grout float
  • Masonry sealer (optional)
  • Sponge and water for cleanup

Installation Steps:

  1. Prepare the Surface:
    • Ensure the cinder block wall is clean, dry, and free of debris or loose material.
    • If the surface is painted or sealed, scuff it up with a wire brush or grinder to create better adhesion.
  2. Apply Thin-Set Adhesive:
    • Use a polymer-modified thin-set suitable for exterior masonry.
    • Apply with a 3/8” notched trowel in small sections (to prevent drying before placing bricks).
  3. Install Brickwebb Sheets:
    • Start with corner sheets first, then work inward with flat sheets.
    • Press each sheet firmly into the adhesive, ensuring good contact between the brick and wall.
    • Overlap the mesh backing for seamless spacing.
  4. Allow to Set:
    • Let the adhesive cure for 24 hours before applying grout.
  5. Apply Grout:
    • Use a grout bag or tile float to fill the joints.
    • Once the grout is stiff but not fully dry, use a joint tool or sponge to smooth the grout lines.
  6. Finishing Touches:
    • Once fully cured, consider applying a masonry sealer to enhance durability and protect against moisture.
