Craftsmanship Canlon | Urban renewal requires the inheritance of history, Canlon put invisible waterproof coats on old buildings

Not long ago, the General Office of the CPC Central Committee and the General Office of the State Council issued the Opinions on Continuously Promoting Urban Renewal, which emphasized "promoting the optimization of urban structure, improvement of functions, continuation of cultural heritage, and improvement of quality, and building livable, resilient, and smart cities". Urban renewal is not only the reconstruction of urban space, but also the reshaping of urban functions, the improvement of living quality, and the inheritance of historical culture.

A city is an organic life form, and its renewal is linked to history on one end and the future on the other. Urban renewal must first handle the relationship between protection and development, and renew itself while protecting and inheriting. A city’s historical relics, cultural relics, and humanistic heritage are important parts of the city’s life form.

As people's living standards continue to improve, they have gradually developed a sense of respect and love for historical and cultural heritage, and have gradually established a sense of protection. Governments at all levels have also paid more attention to the protective repair of historical and cultural blocks and immovable cultural relics, avoiding the situation of "all cities and towns look the same". Instead, they should follow the principle of "repairing the old as it is" and "repairing the new as it is", protect the authenticity and integrity of historical and cultural heritage, preserve its material form and historical information, and continue the lifestyle and cultural memory it carries.

In promoting urban renewal while protecting and inheriting historical and cultural heritage, we often face the problem of not damaging old walls or the appearance of the base . We follow the principle of "physical examination first, then renewal, no physical examination, no renewal", and take protective measures such as waterproofing and anti-corrosion to avoid water leakage, rotting, moss and damage to decorative layers of historical value . We carry out high-quality repairs, "micro-transformations" and "organic renewal".

In order to provide the market with a waterproof coating that can effectively prevent water leakage from the substrate without affecting the original appearance of the substrate and the decorative effect, in June 2025, Canlon officially launched the RC280 weather-resistant transparent waterproof coating for walls. This product is based on pure acrylic copolymer emulsion synthesized by advanced polymerization technology and is a one-component water-based waterproof coating developed with a variety of functional additives. After film formation, it is transparent and has almost no visual changes when attached to the substrate, thus achieving "invisible protection" and "traceless protection" .

When urban renewal refuses to be “uniform”, waterproof solutions need to be “tailored to the needs”. We can see that whether in laboratory results or in practical applications, when RC280 weather-resistant wall transparent waterproof coating is applied to the rough stone surface, it will not affect the original shape and effect of the wall, truly achieving “silent moisturizing”. Let old buildings be covered with invisible waterproof coats, and urban renewal construction will have a more humane choice.

Urban renewal is a long journey of practice. Canlon is willing to use waterproof technology as a pen and ingenious engineering as ink to write stories of protection and innovation in every inch of the city's texture, so that every building has reliable waterproof protection and every block retains a unique cultural memory.
