Supplied as pre-blended, breathable dry powders, EcoMortar® delivers exceptional workability, durability, and long-term performance for both restoration and new construction. Designed to support natural moisture movement and structural flexibility, EcoMortar® creates surfaces that age gracefully while providing superior resistance to cracking, weathering, and deterioration — all without cement or synthetic additives.
EcoMortar® Base is a cement-free lime mortar designed to serve as the scratch and brown coat in traditional stucco and lime render systems, providing a strong, breathable foundation for exterior and interior applications.
EcoMortar® Finish F3.5 is a high-performance finishing coat crafted with NHL 3.5, offering enhanced strength and weather resistance for durable, refined exterior surfaces.
EcoMortar® Finish F2.0 is a soft, slow-curing, highly breathable finish coat made with NHL 2, specifically designed for historic restoration and fragile masonry substrates. Its gentle curing process allows it to bond gradually with deteriorating surfaces without trapping moisture or placing excessive stress on the substrate, making it ideal for preserving and restoring delicate historic walls.
Together, EcoMortar® Base, F3.5, and F2.0 form a complete natural lime stucco system that blends European tradition with modern performance – refining both contemporary architecture and heritage structures.
EcoMortar® is designed for professionals who value material honesty, long-term performance, and architectural integrity. Rooted in traditional lime construction, EcoMortar® allows walls to breathe, move, and mature naturally – supporting healthy building envelopes across both contemporary and historic projects.
Applied in traditional multi-coat applications, EcoMortar® forms durable lime render and stucco systems that protect masonry while allowing it to age naturally. Whether used on stone, brick, or masonry substrates, EcoMortar® provides a natural, breathable solution that strengthens the wall without sealing it shut.

EcoMortar® Lime Stucco System forms resilient, enduring exterior surfaces that work with the natural movement of masonry. Ideal for exterior façades and traditional or modern substrates, EcoMortar® builds layered lime systems that safeguard walls while preserving their inherent balance, offering exceptional flexibility and far greater crack resistance than conventional cement-based renders.
Ideal for stone, brick, and masonry substrates, EcoMortar® supports restoration work, new construction, and architectural detailing where compatibility, breathability, and performance matter. As it cures, the lime gradually hardens into a stone-like finish, reinforcing the structure beneath while allowing moisture vapor to pass freely.
The result is a stucco system that evolves with the building – developing character over time while delivering dependable performance in a wide range of climates and architectural styles.
EcoMortar® forms lime surfaces that are both resilient and expressive, allowing walls to breathe and age gracefully while revealing depth, texture, and enduring natural character.
EcoMortar® is a fully integrated lime stucco system engineered for new construction, crafting walls that are durable, breathable, and naturally beautiful. From scratch coat to brown coat to finish coat, each layer is carefully designed to work in harmony, providing superior performance, long-lasting adhesion, and a finish that honors the natural movement of masonry while meeting modern construction standards.
Breathable & Balanced: Allows moisture to move naturally through walls, preventing trapped water and promoting healthy substrates.
Crack-Resistance: Adapts to structural movement, reducing cracks and extending the life of your stucco system.
Durable Foundation: EcoMortar® Base creates a strong scratch and brown coat that supports the finish and ensures long-term adhesion.
Refined Finishes: EcoMortar® F3.5 provides a resilient finishing coat for high-performance façades, while F2.0 offers a softer, slow curing finish for delicate areas.
Architectural Versatility: Works on stone, brick, and masonry substrates, ideal for residential, commercial, and design-driven projects.
Sustainable & Safe: Cement-free, zero VOC, and environmentally responsible – a natural choice for eco-conscious construction.
Older masonry and historic buildings require care – traditional cement-based plasters can be too rigid and fast-drying for delicate substrates. When applied over aged or fragile surfaces, cement can dry hard and quickly, pulling away or damaging the underlying material.
EcoMortar® F2.0 is different. Formulated with NHL 2.0, it starts soft and pliable, allowing it to wrap gently around delicate masonry. As it cures, it gradually hardens over time, strengthening the surface without disturbing the original substrate. By the time it reaches full stone-like durability, the historic fabric beneath remains intact and preserved.
With EcoMortar® F2.0, restoration professionals can repair, protect, and reinforce fragile surfaces while maintaining the authentic character and breathability of the building – a natural, careful solution for conservation and historic projects.
For areas that demand higher strength or greater exposure, EcoMortar® F3.5 delivers durable, breathable performance.Formulated with NHL 3.5, it provides enhanced durability and weather resistance while still remaining flexible and breathable, making it ideal for new pointing, repairing worn joints, or finishing exterior lime surfaces. F3.5 gradually hardens into a strong, stone-like finish that reinforces the masonry without compromising the delicate underlying substrate, allowing restoration projects to achieve both structural integrity and visual authenticity.
Whether you’re creating new masonry joints or repointing historic structures, EcoMortar® F3.5 delivers superior performance and compatibility. Unlike traditional cement mortars, which can dry too quickly and crack or damage surrounding masonry, EcoMortar® F3.5 is formulated with NHL 3.5 to provide the ideal balance of strength, flexibility, and breathability.
It allows joints to perform naturally, accommodating subtle movement while gradually hardening into a durable, stone-like finish. The result is strong, long-lasting pointing that protects and reinforces masonry without compromising the integrity or appearance of the surrounding surfaces.
Ideal for stone, brick, and masonry in both new construction and restoration projects, EcoMortar® F3.5 ensures joints that are visually seamless, structurally sound, and architecturally authentic.

EcoMortar Base F3.5 – Mix for 4 to 5 minutes with a whisk mixer (450 to 500 rpm). High-speed mixers (more than 500 rpm) are not recommended as they can over-mix the product and modify its performance. Manual mixing is not recommended. WATER ADDITION 1.5 to 2 gallons (192-256 fl oz.) of water per 35kg bag.
EcoMortar Finish F3.5 – Mix for 4 to 5 minutes with a whisk mixer (450 to 500 rpm). High-speed mixers (more than 500 rpm) are not recommended as they can over-mix the product and modify its performance. Manual mixing is not recommended. WATER ADDITION 1.3 – 1.7 gallons (167-217 fl oz.) of water per 35kg bag.
Apply on dampened, clean, and sound substrates. Do not apply to frozen surfaces or in direct sun on hot days. Ensure proper mechanical keying for optimal adhesion (e.g., open texture or scoring). Do not apply in layers thicker than 3/8″ per coat. For thicker builds, apply in multiple coats, allowing each layer to partially set before the next. Wait a minimum of 6 days between scratch and brown coat. Spray the scratch coat with water daily for the first 3 days, then moist it again 20 minutes prior to the brown coat application. Let the brown coat dry for 5 to 7 days, before application of the EcoMortar® Finish. Wet the brown coat for the first 2 days, then moist it once more 20 minutes before applying the EcoMortar® Finish coat.
WORKING TEMPERATURE
Apply between 8°C and 30°C (46°F to 86°F). Lightly dampen substrates before application. Avoid rapid drying from heat or wind; cure gently with water misting if needed. Protect fresh mortar from frost and drying winds for at least 10 days after application. Seal opened bags immediately after use. On hot or windy days, lightly mist the surface every few hours for the first couple of days to prevent premature drying.
