• Q: What makes ProMason Supply different?
  
  
• A: We specialize in high-quality materials for historic masonry, understand the unique needs of these projects, and offer individual project-quantity materials. Please feel free to contact us via email if you need help with material selection at info@promasonsupply.com

• Q: Why shouldn't I use any mortar from the hardware store on historic buildings?
  
  
• A: Modern mortars often contain high concentrations of Portland cement, which is too hard for old brick and stone and can cause damage. Our lime-based mortars allow the structure to move and breath without modern control or expansion joints or building envelopes.

• Q: What's the difference between hydraulic and non-hydraulic lime mortar?
  
  
• A: Hydraulic lime sets with water, suitable for damp conditions and a faster set. Non-hydraulic lime hardens by absorbing CO2 from the air and is typically suitable for interior work. Hydraulic lime mortars are also appropriate for interior applications.

• Q: How do I choose the right mortar color?
  
  
• A: Consider the existing mortar color as well as brick/stone color, architectural style, and surrounding environment. We offer small-quantities to help you find your match or find what colors might be combined/mixed for a great match.

Understanding Lime Mortars

• Q: Why is lime mortar preferred for historic masonry?
  
  
• A: Lime mortar is softer and more flexible than modern cement mortars, allowing historic structures to move, breathe, and also have a self healing property that is sympathetic to historic structures. This prevents moisture buildup and damage.

• Q: What are the different types of lime used in mortar?
  
  

We offer various types of lime mortar concentrates which are used for making brick or stone mortar with general guidelines as follows:

PHL 2.0 (Feebly Hydraulic)

• Strength: Lowest compressive strength among the PHLs.
• Setting Time: Sets slowly.
• Uses:
• Ideal for very soft and fragile masonry, where minimal strength is required.
• Often used for interior plastering and repointing delicate historic structures.
• Provides good breathability and flexibility.

PHL 3.5 (Moderately Hydraulic)

• Strength: Medium compressive strength.
• Setting Time: Sets at a moderate pace.
• Uses:
• The most versatile type, suitable for a wide range of applications.
• Commonly used for repointing brick and stone, both interior and exterior.
• Offers a good balance of strength, breathability, and workability.

PHL 5.0 (Eminently Hydraulic)

• Strength: Highest compressive strength of the PHLs.
• Setting Time: Sets relatively quickly.
• Uses:
• Suitable for demanding applications where higher strength is needed.
• Often used for structural repairs, foundations, and exterior walls exposed to harsh weather.
• Provides greater durability and resistance to moisture.

• Q: How do I mix lime mortar?
  
  
• A: Proper mixing is crucial. Generally, you'll combine lime, sand, and water in specific ratios. Our products come with detailed instructions. We can also provide guidance on achieving the right consistency.

• Q: What is the "cure" time for lime mortar?
  
  
• A: Lime mortar cures slowly, taking weeks or even months to fully harden. This slow curing allows for proper carbonation and ensures a strong, durable bond. Protect the mortar from rain and frost during the initial curing period.

Common Masonry Repairs

• Q: How do I repair cracks in my brick wall?
  
  
• A: Minor cracks can often be repaired with mortar. Larger cracks may require professional assessment to determine the underlying cause and appropriate repair method.

• Q: What is "repointing"?
  
  
• A: Repointing involves removing deteriorated mortar from the joints and replacing it with fresh mortar. This restores the structural integrity and appearance of the masonry.

• Q: My chimney is leaning. Can it be fixed?
  
  
• A: A leaning chimney is a serious issue and requires professional attention. It may need to be rebuilt or stabilized.

• Q: How do I remove efflorescence (white deposits) from my brick?
  
  
• A: Efflorescence is caused by soluble salts migrating to the surface. Dry brushing can remove light efflorescence. We also offer specialized cleaners for more stubborn cases.

Cleaning and Maintenance

• Q: What's the best way to clean old brick?
  
  
• A: Cleaning methods depend on the brick and soiling. We offer a gentle masonry cleaner for brick which works well with a plastic bristle brush. Always test in an inconspicuous area first.

• Q: How often should I inspect my masonry?
  
  
• A: Annual inspections are recommended to identify any issues early on. Pay attention to cracks, loose mortar, and signs of water damage.
