Case Study of the Micro-Renovation Coating Project in Liufu Community, Liwan District, Guangzhou

I. Project Overview
● Project Name : Liufu Community Old Xiguan Micro-Renovation and Street Facade Improvement Project
● Project Location : Liufu Community, Jinhua Subdistrict, Liwan District, Guangzhou City, Guangdong Province (the area bounded by Shibafu Road, Liufu Road, and Shisanhang Road)
● Construction Units : Jinhua Subdistrict Office and Liufu Community Residents Committee, Liwan District
● Scope of renovation : Exterior walls, fences, and alleyway facades of several old arcade buildings, traditional residences, and other structures within the community.
● Completion time : Phased completion in 2023-2024
● Design Concept : Following the principles of "restoring the old as it was, maintaining harmonious style, and making subtle improvements," the design uses classic beige as the main color to restore the warm sandstone texture of the old Xiguan arcade buildings and cobblestone alleys, giving the community both a historical and lively atmosphere, as well as a clean, tidy, and aesthetically pleasing appearance.
● Paint supplier : Guangdong Yongrong New Building Materials Co., Ltd. (direct supply from the source)
This project uses our company's water-based sand-like stone paint (Guanjing Stone series) + ceramic stone system, perfectly balancing the traditional Xiguan style with modern durability requirements, becoming an excellent example of micro-renovation of old communities in Guangzhou.

II. Material Combination Scheme (Yongrong Old Xiguan Beige Classic System)
Core products:
1.Water-in-sand (crown crystal) YR-9802-22
○ Main color: Old Xiguan Beige YR-9802-22-GX
○ Applications: Large areas of arcade walls and alleyway exteriors, showcasing the natural granite grain and layers.
2.Ceramic Stone YR-9802-15
○ Same color beige ceramic crystal
○ Applications: Plinths, columns, window frames, walls, and other areas close to people; finely textured and wear-resistant with a sandstone-like feel.
3.Collocation Logic
○ Water-coated sand is responsible for the natural stone texture of the large areas of "yellow sandstone," giving it a warm and unified appearance from a distance.
○ Ceramic crystal stone is used in frequently touched areas; it has finer particles and is more resistant to scrubbing.
○ The two materials, in the same color, blend seamlessly, presenting a warm beige tone unique to the old Xiguan area. It is both retro and not overly bright, perfectly integrating with the cobblestone road and blue brick wall.

III. Detailed Explanation of Construction Technology
1.Base layer cleaning: High-pressure water gun + manual removal of loose layer and mold.
2.Crack-resistant treatment: Alkali-resistant mesh cloth + polymer mortar applied in full coat to prevent cracking.
3.Alkali-resistant sealing primer: Apply one coat by roller to completely block alkali and prevent staining.
4.Flexible putty leveling: Apply two thin coats, sand smooth while preserving the subtle texture of the old wall.
5.Water-based sand-textured intermediate coat: Spray one coat of beige intermediate coat to unify the base color.
6.Water-based sandblasting material: Apply two coats of water-on-water spray using a special multi-color spray gun to create a full granite effect.
7.Ceramic stone area: Apply two coats by hand (total thickness 2-4mm) to smooth out imperfections.
8.Hand finishing: Lightly sand down any burrs to ensure a smooth, seamless transition between the two materials.
9.Breathable silicone acrylic topcoat: Apply 2 coats to enhance stain resistance and self-cleaning properties.
10.Natural curing for 7-14 days, during which time it should be covered to protect from rain.
The entire process involves low-pressure spraying and manual finishing, preserving the warmth of the old Xiguan hand-pulled sand walls while achieving the durability and easy cleaning of modern coatings.

IV. Panoramic View Display
● The beige hue appears especially warm in the alleyways of Xiguan, complementing the blue bricks, cobblestone streets, and red window decorations.
● The water-coated sandstone has large, naturally jumping particles, resembling an old yellow sandstone wall from a distance, while revealing vivid details up close.
● The ceramic crystal plinth and column body are smooth and delicate, completely eliminating the troubles of traditional exterior wall paint turning black and peeling.
● The renovated Liufu community is clean yet retains its lively atmosphere; stepping inside feels like stepping back into the old Xiguan streets of the 1950s.
● Having withstood more than two years of typhoons, torrential rains, and scorching heat, the walls remain as new as ever, resulting in extremely high resident satisfaction.
