Product Overview
EcoMortar® F2.0 Finish is a dry, ready-mix lime mortar made with Saint-Astier® Natural Hydraulic Lime NHL 2.0. Engineered as a finishing coat for historic or sensitive structures, it offers excellent breathability, flexibility, and adhesion — all without the use of cement or synthetic additives. EcoMortar® F2.0 is crafted for restoration projects where existing masonry surfaces are aged, delicate, or friable. It provides a gentle, breathable finishing coat that bonds softly without disturbing underlying layers, making it perfect for conservation work where preserving the original structure is essential. As it sets, it gradually transforms into stone, reinforcing the building while respecting its original character. This isn’t just about repair — it’s about thoughtful restoration, bringing strength and life back to historic walls without overwriting their past.
Key Benefits
● Vapour Permeable: Facilitates moisture movement, reducing the risk of trapped moisture and associated damage.
● Cement-Free Composition: Composed solely of natural hydraulic lime, ensuring compatibility with historic masonry and sustainable building practices.
● Enhanced Elasticity: Offers superior flexibility compared to cementitious products, accommodating minor structural movements.
● Environmentally Friendly: Produced with lower energy than cementitious mixes and contributes to CO₂ re-absorption during curing.
Recommended Applications
● Finishing Coat for External Lime Renders: Provides a durable and breathable top layer in lime render systems.
● Restoration Projects: Ideal for use in the conservation of historic buildings requiring breathable and compatible materials.
● Eco-Friendly Construction: Suitable for new builds aiming for sustainability and natural building practices.
