Loam and lime plaster

Loam plaster and lime plaster are both natural plasters with unique properties, applications and benefits.

1. Composition
   • Loam plaster: consists of clay, sand and sometimes straw or other natural fibers. It contains no chemical binders and is completely natural and reusable.
   • Lime plaster: made from lime, sand and sometimes marble powder. It may contain air lime (lime that hardens by CO2 absorption) or hydraulic lime (which hardens by water and chemical reactions).
2. Breathability and moisture management
   • Loam Plaster: Very vapor-permeable and moisture-regulating, absorbs moisture and releases it gradually. Ideal for indoor areas with varying humidity (such as living rooms and bedrooms). Not waterproof and less suitable for surfaces in direct contact with water.
   • Lime plaster: Breathable but less hygroscopic than loam. Has a moisture regulating effect but is more resistant to moisture than loam. Is suitable for bathrooms and exterior walls.
3. Application and processing
   • Loam plaster:
     • Application: mainly for interior walls, suitable for ecological and bio-ecological construction projects.
     • Application: first a thick base coat and can be finished with a thin finish in a color of your choice. It is easy to repair.
     • Drying time: Dries slowly, depending on humidity.
   • Lime plaster:
     • Application: both indoor and outdoor
     • Application: Cures chemically, making it firmer than loam
     • Drying time:Dries faster than clay and hardens over time
4. Sustainability and environmental impact
   • Loam plaster:
     • 100% natural, completely reusable and recyclable
     • Very low CO2 emissions in production
     • non-waterproof
   • Lime plaster:
     • Also a natural product, but producing lime requires more energy (CO2 emissions) than loam.
     • not completely reusable like loam
