Customer Questions & Answers

  • Question: What is Otterbein Natural Hydraulic Lime 3.5 used for?

    Answer: Otterbein Natural Hydraulic Lime 3.5 is primarily used for construction and masonry applications. Its unique hydraulic properties allow it to set and harden in various environments, making it ideal for creating durable, breathable mortars and plasters. This lime is particularly beneficial in heritage restoration projects, where preserving the original building materials is crucial. It's also suitable for modern construction, enabling a balance between flexibility and strength in structures.
  • Question: What benefits does hydraulic lime have over traditional lime?

    Answer: Hydraulic lime, like Otterbein Natural Hydraulic Lime 3.5, sets quickly and can harden under water, offering superior durability compared to traditional non-hydraulic lime. This makes it a versatile option for various weather conditions and environments, ensuring stability in both dry and damp applications. Additionally, its properties lead to better adhesion and reduced cracking, which is essential for long-lasting masonry work, especially in demanding climates.
  • Question: Can Otterbein Natural Hydraulic Lime be used for eco-friendly building projects?

    Answer: Absolutely! Otterbein Natural Hydraulic Lime 3.5 is an excellent choice for eco-friendly building projects. As a natural product, it has a low carbon footprint and offers sustainability benefits. It contributes to energy efficiency in buildings by allowing moisture regulation and promoting healthy indoor air quality. Its ability to breathe well helps prevent mold and mildew growth, which is crucial for both the environment and occupant health.
  • Question: How should I mix Otterbein Natural Hydraulic Lime for mortar?

    Answer: To mix Otterbein Natural Hydraulic Lime for mortar, use a blend of the lime with sand in a 1:3 or 1:4 ratio. Begin with a dry mix, combining the lime and sand thoroughly before slowly adding water to achieve the desired consistency. Aim for a workable paste that is neither too dry nor too wet. Proper mixing is essential to ensure that the mortar can bond effectively with bricks and stones, ensuring robust construction.
  • Question: Is Otterbein Natural Hydraulic Lime suitable for exterior applications?

    Answer: Yes, Otterbein Natural Hydraulic Lime 3.5 is well-suited for exterior applications. Its hydraulic properties allow it to set effectively even in damp conditions, making it ideal for outdoor projects. Whether you're repairing stone facades, repointing brickwork, or applying lime plaster to external walls, this lime offers resilience against environmental stressors while maintaining breathability and flexibility in the structure.
  • Question: How long does it take for mortar made with Otterbein Natural Hydraulic Lime to set?

    Answer: Mortar made with Otterbein Natural Hydraulic Lime typically begins to set within a few hours, depending on environmental conditions such as temperature and humidity. Full curing can take several days to weeks, allowing the mortar to reach optimal strength. This gradual curing process is beneficial, as it helps the mortar adapt to settling and any shifts in the masonry structure, thereby enhancing durability and longevity.
  • Question: What type of finish can I achieve with Otterbein Hydraulic Lime?

    Answer: Using Otterbein Natural Hydraulic Lime 3.5 allows for a variety of finishes, from rough-textured rustic looks to smooth, polished surfaces.
