Product Overview
Fermacell Fine Surface Treatment supplied in a 10L container. This ready-to-use dispersion filler is formulated for fine finishing and joint filling of Fermacell Gypsum Fibre Boards and other interior wall or ceiling substrates.
Designed to produce a smooth, even surface, it achieves high-quality Q3 and Q4 finish standards where superior surface uniformity is required prior to decoration. The product offers a creamy, easily workable consistency with strong adhesion and excellent sanding characteristics.
Suitable for both manual and mechanical application, it ensures efficient coverage, quick preparation, and a flawless final surface ready for paint or wall coverings.
Features & Benefits

Installation Guidance
- Preparation: Ensure substrate is clean, sound, dry, and free from dust. Apply only at temperatures above +5°C.
- Application: Use a Fermacell spatula or similar stainless-steel trowel; apply in layers not exceeding 0.5mm.
- Sanding: Once dry, sand lightly with 100–120 grit paper to achieve a smooth finish; remove dust before further coating.
- Drying time: Dependent on substrate, layer thickness, ambient temperature, and humidity.
- Safety: Wear goggles and a mask during sanding operations; dry spatulas thoroughly after cleaning to prevent corrosion.
Compliance & Performance
- Material type: Ready-to-use dispersion filler designed for gypsum fibreboard and mineral substrates.
- Finish quality: Suitable for Q3 and Q4 level finishes in accordance with surface quality classifications.
- Workability: Long open time for easy application and levelling.
- Environmental compliance: Solvent-free, plasticiser-free, and low-VOC for safe indoor environments.
- Important note: Apply in thin layers; do not exceed 0.5mm thickness per coat to maintain adhesion and drying performance.
