Supplied Finish Options
Uncoated / Natural Mineral Grey
Supplied without factory paint film. Suitable where on-site architectural painting, industrial post-coating, or raw mineral aesthetics (subject to datasheet suitability) are planned.
Pre-Primed (Ready for Topcoat)
Factory-applied alkali-resistant primer equalises board absorption and prepares the face for compatible exterior acrylic/silicone facade topcoats.
Factory-Coated (Surface-Painted)
Industrial multi-layer opaque or semi-transparent architectural facade coating applied over a mineral grey core. Cut edges expose the natural core and require matching edge sealer/touch-up where specified.
Through-Coloured (Mass-Pigmented Core)
Mineral pigments are integrated throughout the board core so face, chamfers, and cut edges share the same tonal family, typically paired with a transparent hydrophobic or matte protective treatment.
Hydrophobic / Water-Repellent Impregnation
Transparent vapour-permeable treatment reducing capillary rain absorption and efflorescence risk while preserving natural mineral matte appearance.
UV-Stabilised Architectural Topcoat
Formulated for high solar exposure elevations to support colour retention; exact binder chemistry (pure acrylic / PVDF / polyurethane) is confirmed per selected series.
Easy-Clean / Anti-Graffiti Protective Coat (Enquiry-Based)
Project-specific protective surface film evaluated for ground-floor public facades, schools, and transit buildings subject to minimum order volume.
Sanded & Calibrated Precision Surface (SF-SANDED / SF-CALIBRATED)
Mechanically sanded face or double-sided calibrated thickness tolerance engineered for industrial coating lines, laminating substrates, and precision CNC facade fabrication.

Frequently Asked Technical & Commercial Questions
What is the technical difference between Factory-Coated and Through-Coloured fibre cement panels?
Factory-coated panels feature an opaque or semi-transparent architectural paint system applied onto a natural mineral grey fibre cement core; saw-cut edges expose the grey core and require compatible edge sealing. Through-coloured panels incorporate mineral pigments throughout the entire board matrix so face and cut edges share the same colour family, typically finished with a matte hydrophobic or translucent protective coat.
Can uncoated (natural grey) fibre cement boards be painted on site after installation?
Yes, provided boards are dry, clean, dust-free, and coated with an alkali-resistant mineral/acrylic primer followed by a breathable exterior facade paint recommended for fibre cement substrates. Ordering pre-primed boards reduces site preparation risk and improves topcoat uniformity.
Why must texture orientation and rear sanding arrows be tracked during cutting?
Woodgrain (TX-WD), coursed stone (TX-ST), brick (TX-BR), linear ribs (TX-LN), and sanded matte boards (TX-SD) interact directionally with daylight. Rotating one panel by 90° or 180° on a facade elevation creates visible shade differences even within the same production batch.
Do mineral concrete-look and through-coloured boards exhibit natural shade variation?
Yes. Because fibre cement is manufactured from natural mineral raw materials (cement, silica, mineral fillers, and cellulose/reinforcing fibres), subtle clouding and lot-to-lot tonal character are part of authentic mineral surfaces. For continuous architectural elevations, order the complete elevation quantity in a single production lot.
How are architectural colours and RAL references verified before production?
Screen swatches provide initial palette orientation only. Standard factory-coated shades and project-specific RAL/NCS coating enquiries are always confirmed against physical hand samples and minimum coating batch thresholds before proforma invoice approval.
What is included in a SerFibro architectural sample box and how is courier dispatch arranged?
Sample dispatches contain cut hand-specimens (commonly ~150 × 200 mm or ~200 × 300 mm) showing true core cross-section, relief depth, and surface finish state, labelled with reference codes. Qualified architectural practices, contractors, and importers can request samples directly via our Sample page or WhatsApp desk.
