APPLICATION

  • Surface Preparation:
    • Ensure cleanliness: Clean the surface thoroughly, removing oil, grease, dirt, and organic growth like moss and lichen. Fungicidal Wash can be used for organic growth removal.
    • Rust removal: Wire brush rust from bolt heads on roof sheets before sealing them with Trowel Mastic.
    • Priming porous surfaces: Prime porous surfaces with Bituminous Primer to seal them, allowing for thorough drying.
  • Method of Application:
    • Lubrication for tools: To aid application, lubricate tools with white spirit or paraffin.
    • Application process: Use a trowel or putty knife to apply Trowel Mastic, ensuring it is forced into cracks and joints and smoothed on both sides.
    • Reinforcement for larger cracks: For cracks or joints exceeding 3mm, reinforce them with glass fibre scrim and cover with a second application of mastic.
