Repointing is the process of renewing the mortar joints between bricks, restoring both the structural integrity and visual appeal of masonry. At North Shore Brickwork Milwaukee, we emphasize using the right materials to ensure long-lasting, weather-resistant results.
Essential Materials for Repointing Brickwork
1. Mortar
The most important material is the mortar mix itself. The right blend depends on the age and type of your brickwork:
- Lime mortar for historic or softer bricks, allowing flexibility and breathability.
- Cement-lime-sand mortar for modern structures, providing strength and durability.
- Color-matched mortar to ensure the repair blends seamlessly with the existing joints.
2. Sand
Clean, sharp sand is critical for strength and texture. The particle size is chosen to match the original mortar, ensuring consistency in both appearance and performance.
3. Portland Cement (when appropriate)
Used in combination with lime and sand for newer buildings. It creates a harder mortar suitable for high-strength masonry while maintaining flexibility.
4. Lime
Essential for workability and breathability. Lime-based mortars are particularly important in Milwaukee’s freeze-thaw climate to prevent cracking.
5. Water
Clean, potable water is used to mix the mortar. Water quality directly affects the mortar’s strength and setting process.
6. Additives or Pigments
For specialized projects, additives improve workability, durability, or water resistance. Pigments are often added to achieve a perfect color match.
