GRC Super Weather Ability Sun & Rain Exterior Wall Paint

Product Category

GRC Exterior Wall Paint — Super Weather Ability is a water-based acrylic coating built for façades that take the full force of the weather. Sun and rain are what age an exterior wall fastest, and this system is formulated against both: UV-stable pigments that hold their colour, and a water-repellent surface that keeps rain on the outside where it belongs.

The cured film stays breathable, so any moisture already in the substrate can still escape rather than pushing the coating off the wall from behind. Supplied as CR-FG708 in 20 kg barrels, it applies by roller, brush or spray over a primed mineral substrate.

Key Characteristics:

1. Super Weatherability: Engineered to resist the combined effects of intense sunlight and heavy rainfall, maintaining long-lasting performance without fading, chalking, or peeling.

2. Sun Protection: Excellent UV resistance helps prevent color fading and gloss loss caused by prolonged sun exposure.

3. Rain Protection: Strong water resistance repels rain and moisture, reducing water penetration and protecting the wall surface.

4. Breathable Film: Allows the substrate to breathe while blocking external water, minimizing blistering and cracking.

5. Alkali & Mildew Resistant: Protects against alkali attack from masonry and inhibits mold and algae growth.

6. Strong Adhesion: Bonds firmly to exterior substrates for durable, long-term protection.

7. Color Retention: Keeps exterior walls looking fresh and vibrant for longer.

8. Easy Application: Suitable for roller, brush, or spray application with good leveling and coverage.

Best Applications:

• Exterior Façades in Strong Sun: south- and west-facing elevations where UV exposure bleaches ordinary emulsion within a couple of seasons
• Rain-Exposed and Coastal Walls: buildings that take driving rain or salt-laden air and need the surface to shed water rather than absorb it
• Alkali-Prone New Masonry: fresh render and concrete, where the coating has to resist alkali attack while the substrate cures
• Refurbishment Over Sound Coatings: recoating weathered exterior walls without stripping back to the substrate

Advantages:

• Built for Two Enemies at Once: most exterior emulsions answer either UV or water; this one is formulated against the pair, which is what a façade actually faces
• Colour That Stays Put: UV-stable pigments mean the wall still matches the swatch after a few summers instead of drifting chalky and pale
• Breathes While It Repels: water stays out but vapour still escapes, so trapped moisture does not blister the film from behind

Construction Steps

Where the Filler Comes From

Heavy calcium carbonate is the backbone of a water-based coating. It decides how the film builds, how hard it dries and how well it stands up to scrubbing — and it is the mineral that lets a formulator pull back on titanium dioxide, the most expensive ingredient in the can.

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 alongside Haicheng in Liaoning, Qingyang in Anhui and Hezhou in Guangxi. It is the largest calcium carbonate cluster in central China, and its calcite runs to 98% CaCO3 at 92–95 whiteness: the grade that carries opacity and brightness into the film instead of simply adding bulk.

Because GRC owns the mine as well as the plant, that material reaches the mix directly rather than through a broker. Whiteness and particle grading stay steady from batch to batch — and so does the cost base when mineral prices move.

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

Output of 60,000 tons a year means volume orders move without drama, and the same quality-control gates apply to every batch. The chemistry is water-based and low-emission, formulated to clear international standards including RoHS, REACH and France A+. Shipments reach more than 60 countries, and the reason customers come back is straightforward: a finish that holds up, at a price that works.
