Buildings face many challenges: moisture, cracking, and weakening over time. Fortunately, hydrated lime offers a natural solution. It improves strength, durability, and workability in plaster and mortar. Using lime ensures buildings last longer while reducing maintenance costs.
Why Traditional Plaster Fails
Many plaster and mortar mixes crack or degrade quickly. Key reasons include:
-
Exposure to moisture and weather conditions
-
Poor workability leading to weak application
-
Materials that do not allow walls to “breathe”
-
Long-term maintenance costs that add up over time
These issues reduce the lifespan of buildings and increase repair costs, making traditional plaster less reliable over time.
How Hydrated Lime Strengthens Buildings
When added to plaster or mortar:
-
Increases durability, making walls stronger over time
-
Improves workability, filling cracks and voids easily
-
Enhances weather resistance, reducing moisture damage
-
Allows breathable walls, ideal for heritage or traditional buildings
-
Provides cost savings through fewer repairs and faster application
Consequently, lime ensures structures remain solid and protected for decades.
Benefits for Builders and Homeowners
-
Longer-lasting walls with fewer cracks and fractures
-
Smooth, easy-to-apply plaster that saves time and effort
-
Reduced moisture damage for safer, healthier buildings
-
Cost-effective solution minimizing maintenance expenses
-
Ideal for restoring older or heritage structures
Overall, using hydrated lime enhances strength, durability, and workability, creating safer, longer-lasting buildings while reducing maintenance costs.
Interesting Fact
Hydrated lime undergoes a natural chemical reaction with carbon dioxide in the air, called carbonation, which gradually hardens the plaster. This process not only strengthens the walls over time but also creates a naturally water-resistant surface. As a result, lime-based plaster becomes more durable, protects against moisture damage, and maintains a breathable structure that helps prevent mold and structural decay.
