JCDecaux is a wholly-owned enterprise established in China by the world-renowned specialty mortar company - Parex Group, and has participated in the drafting and compilation of many national industry standards such as "Polymer Cement Waterproof Coatings", and is also the designated supplier for the construction of the Bird's Nest Stadium.
 
Pali Group is a global chemical building materials enterprise that provides special dry-mix mortar technical solutions and coating products for the construction industry, and one of the leaders in China's special mortar industry, K11 waterproof slurry, TTB tile adhesive, beauty joint, putty and other products have won praise from major real estate developers and the general public for their reliable quality, and have become a high-quality brand in the Chinese market.
 
As the core of the globalization strategy of Parex Group, JCDecaux is responsible for the operation of China and even the entire Asian region, with relatively complete sales channels, with offices in major cities in China, sales outlets all over the country, channels sinking to second-tier cities, and a series of JCDecaux waterproof products can also be found on online platforms, with a wide range of types.
 
JCDecaux household waterproof coatings are mostly cement-based formulas, including polymer cement waterproof coatings (referred to as JS or K11), polymer cement waterproof slurry, cement-based permeable crystalline waterproof coatings, and on this basis, two categories of general and flexible are developed, both of which have excellent impermeability and durability, and the drying time of 1-3 hours is also more efficient than other coatings.
 
Generally speaking, JCDecaux's general-purpose coatings can be waterproof on both sides and have stronger aging resistance, and are often used in basements, garages and other long-term humid closed environments, but general-purpose coatings are more rigid, and they are not well resisted to deformation and cracking caused by large temperature differences or ground subsidence, and their performance in outdoor environments such as roofs and exterior walls is slightly inferior. The flexible coating that achieves the purpose of waterproofing through film formation has a better coverage effect on cracks below 2mm, and the flexibility of 30% can also withstand slight shocks and slight displacements, making up for the shortcomings of general-purpose coatings, but the price is much more expensive, and it is mostly used in the corners of walls and pipes around the water-permeable parts.
 
"JCDecaux Color Universal K11 Waterproof Paste" and "JCDecaux Color Flexible K11 Waterproof Paste" are new series in 2017, which have not only passed the Ministry of Environmental Protection Ten Ring Certification and ISO certification, but also passed the French A indoor environment testing certification, which is more environmentally friendly. The price of a single barrel of general-purpose 17.7kg is about 400 yuan, and the price of a flexible 18.2kg single barrel is about 500 yuan. If the waterproof area is large, it is more affordable to choose the two-barrel package, and it also comes with two packs of 2kg of water without leakage, which is better for use.
 
For some older houses, the problem of water leakage caused by wall cracking is very common, but after all, it is not a large-scale decoration, and the selection of the above two waterproof slurries is obviously too wasteful, it is recommended to choose "Degao Roof Repair King", which is still a cement-based formula, which can be used both indoors and outdoors, and the price of 1kg is about 120 yuan, and the area of about 1 square meter can be painted.
