OPTOLITH Optoplast EcoFinish 03 –

Fine-Grained Mineral Render with 0.3 mm “Lamb” Texture

OPTOLITH Optoplast EcoFinish 03 is an ultra-fine, thin-layer mineral render with a 0.3 mm “lamb” texture, designed for decorative and protective façade finishing in ETICS systems and on traditional mineral substrates. Thanks to its delicate structure, it is ideal for projects requiring a smooth, subtle, and modern visual effect. Based on natural mineral components, the product offers excellent vapor permeability and biological resistance—without the need for biocides.

Applications of OPTOLITH Optoplast EcoFinish 03:

• Decorative finishing of façades in ETICS insulation systems (EPS or mineral wool)

• Thin-layer rendering on mineral substrates such as cement and cement-lime plasters, concrete, brick

• Recommended for modern and minimalist architectural designs, as well as for the renovation of historic buildings

Key Features and Benefits:

• Ultra-fine 0.3 mm “lamb” texture – smooth, elegant, and modern façade finish

• Mineral-based composition – naturally resistant to algae, fungi, and mold

• High vapor permeability – allows walls to breathe and moisture to escape

• Excellent adhesion to mineral substrates – long-lasting stability and durability

• Eco-friendly and safe formula – free from synthetic resins and solvents, environmentally and user friendly

Technical Data:

• Type: mineral, thin-layer render

• Texture: “lamb” structure, 0.3 mm grain size

• Color: white (can be tinted in selected colors)

• Consumption: approx. 1.5–1.8 kg/m² (depending on substrate smoothness)

• Open working time: approx. 20 minutes

• Application temperature: from +5°C to +25°C

• Packaging: 25 kg paper bag

Application Guidelines:

The substrate must be dry, clean, stable, and primed with a suitable primer (e.g., Optogrund). Apply the material evenly using a stainless steel trowel, then create the texture with a plastic float. To avoid streaks and inconsistencies, apply using the “wet-on-wet” method over entire façade sections. Protect freshly applied render from rain, direct sunlight, and wind until fully dry.
