Glazed Metallic Stone Coating for High-End Building Facades
JOSME has introduced a Glazed Metallic Stone Coating, which uses weather-resistant acrylic emulsion as the foundation material, mixed with calcined sand aggregates and metallic pearlescent pigments. Final coating has layered colour gradation, ceramic surface roughness and metallic shimmering appearance. The total weight is managed to be less than 4 kg/㎡, realising lightweight facade decorating. This product is suitable for the facade construction of office buildings, hotels, homes, banks, hospitals and government buildings. Standard packaging 40kg/drum,colors,surface effects and packaging options may be customised according to varied project specifications.
What Is Glazed Metallic Stone Coating
Glazed Metallic Stone Coating is different from normal stone paint. It combines sintered stone aggregates and high-purity metallic colours to modified resin substrates to create multi-angle light refraction surfaces, recreating the ornamental impact of premium granite and glazed ceramic surfaces.
This solution tackles three typical challenges in facade engineering construction: high structural strain produced by natural stone slabs, flat and single ornamental appearance of standard architectural coatings, and colour fading of common coatings under long-term UV exposure. Together with comprehensive primer, intermediate coat and topcoat systems it creates solid facade finishing layers, combining lightweight construction and long-term outdoor colour stability.

Core Product Advantages
Metallic Effect: Ceramic texture with metallic shimmer that changes with the angle of light, in matching aluminium panels with less weight and expenditure.
Fine cracking is prevented by crack-resistant film with an elongation of 150%-200%. Ideal for new construction and maintenance.
Weather Resistance – 2,000+ hours, ASTM G154. Resists changes in temperature and UV, keeps colour long time.
Self Cleaning - Smooth covering repels dust. Rain washes dust away for less upkeep.
Low VOC & Light weight — Water base; <4 kg/㎡ for old-building restoration and EPS / XPS boards.
Quality Control
The Glazed Metallic Stone Coating is fully inspected during the entire process before delivery, which may stabilise the quality of the batch.
Particle Size Calibration - Uniform distribution for uniform texture of surface in batches.
colour Detection – Spectrophotometer with Delta E < 0.5 to match the arrangement of pigment and colour presentation.
Alkali Resistance – 48 hour soak in saturated calcium hydroxide; no burning or peeling on fresh concrete.
Freeze-Thaw integrity — 50+ cycles simulate low temperature conditions, ensuring structural integrity.
Keeps the shine Mechanical abrasion testing is to determine long term endurance of metallic glaze refraction.
A sample from each manufacturing batch is retained for long term file reference for project colour and performance verification at subsequent phases.
Application Scenarios
Office Buildings & Government Facilities – Clean style of facades; self-cleaning lowers daily upkeep.
Hotels & Luxury Villas – Aluminium panel effect on curved and contoured surfaces where stiff cladding cannot be put.
Hospitals & Banks Stable immaculate look for long-term high standards of functioning.
Coastal & High Humidity Areas – Compact film resists efflorescence and chemical attack.
Renovation & ornamental Components – Trowel application is ideal for ornamental columns and curved panels that do not lend themselves to aluminium curtain walls.
Customization & Ordering
JOSME provides diversified project customization services to meet personalized engineering demands, including custom color matching with physical sample confirmation, adjustable particle size for different texture effects, exclusive surface finish design and private-label packaging solutions.
Standard products can be delivered within 2–3 working days. Custom color matching and private-label orders take 7–15 working days for production. Product physical swatches and samples can be provided for pre-order confirmation.
FAQ
Q1: What is the ornamental effect of coating?
A1: Trowel structure produces ceramic texture with metallic lustre. The aluminium panel with multi-angle refraction is suitable for the facade of a light-luxury hotel, office and government.
Q2: How does the self-cleaning operate in practice?
A2: Dense coating prevents dirt adherence. Rainwater washes away everyday dust and stains reducing facade maintenance expense.
Q3: What are the benefits vs aluminium curtain wall panels?
A3: Lighter , no structural loads . Rigid aluminium is not able to handle curved and shaped components. The flexible trowel method can.
Q4: Will the metallic glaze wear off or oxidise outside?
A4: The pigments are encapsulated to avoid oxidation. Withstands over 2,000 hours of ASTM weathering and will keep its colour and sheen for years to come.
Q5: Are they suitable for external insulation systems?
A5: High-elastic film, adaptable to EPS/XPS. For project specific compatibility please contact our technical staff.
