GRC Crystal Diamond Sand Paint

Product Category

GRC Crystal Diamond Sand Paint is crafted with a unique silicone-acrylic emulsion, specially chosen combustion sand and high-quality additives. Once applied, it offers a sophisticated look with a strong European flair.

This paint merges the benefits of elastic coatings and stone-like finishes, highlighting the strengths of both. Not only does it enhance appearance and texture, but it also makes application easier, making it ideal for high-end construction projects. Since no spraying is required, it significantly reduces on-site application complexity.

Key Characteristics:

1. Environmentally Friendly and Non-Toxic: made from ceramic sand and inorganic water-based coatings fired at high temperatures, free from toxic emissions
2. Colourful and Diverse: rich colours, diverse textures and a 3D effect that brings walls to life
3. High-Strength Self-Cleaning: a hydrophobic surface that resists dirt, acid, alkali and corrosion
4. Crack Resistance: the durable surface resists scratches and cracking, maintaining strength like ceramic over time
5. Super Weather Resistance: resistant to mildew, moisture and temperature extremes
6. Bright and Lasting: calcined at high temperatures, the colours remain bright and unfaded

Best Applications:

• Interior and exterior wall decoration of high-end buildings; wall and cylindrical decoration of enterprises, institutions and commercial buildings.

Advantages:

• Self-Cleaning Surface: rain washes the film clean, so an exterior wall keeps its brightness instead of streaking and greying
• Handles Thermal Movement: flexible enough to take the expansion and contraction of a façade through a full year of seasons without crazing
• Crisp or Rustic, Same Product: the grain is set by the trowel, so the same material delivers a fine plain texture or a pronounced rough finish

Where the Sand Comes From

Every stone-effect finish lives or dies on its aggregate. Ours comes from Nanzhao County in Nanyang, Henan — the district GRC's own mineral resources sit in, and one of China's four major heavy calcium carbonate bases.

Nanzhao's coloured sand is quarried from marble and granite rather than manufactured, so the colour is intrinsic to the stone instead of dyed into it. That distinction decides how a façade ages: dyed and sintered sands fade under UV and bloom white where rain runs off, while a mineral colour has nothing to lose. The grain runs at Mohs 7, and it is large-scale, carefully sorted quarrying that holds the shade steady from batch to batch — the inconsistency that has historically kept natural sand out of large projects.

The coat underneath draws on the same district. Calcite from Nanzhao runs to 98% CaCO3 at 92–95 whiteness, and as a functional filler it builds film thickness, hardness, water resistance and scrub resistance into the film rather than simply bulking it out.

About Our Company

From a plant in Nanyang, Henan, GRC has supplied building coatings for more than 16 years. Annual output reaches 60,000 tons across interior and exterior wall paints, floor coatings, waterproofing, primers and decorative finishes. Every batch clears the same quality gates before it ships, which is what keeps delivery dates reliable for contractors, specifiers and distributors working to a programme.

Why Choose Us

Annual output runs to 60,000 tons, and every batch passes the same quality-control gates before it ships, which is what keeps delivery dates reliable. Formulations are built on low-emission, eco-friendly chemistry that satisfies international standards. GRC coatings now reach customers in more than 60 countries, and that export record rests on a simple proposition: coatings that look right, last, and stay affordable.
