In order to provide space for heat expansion and contraction, and avoid reasonable dimensional errors, all tile tiles are left with gaps. For aesthetic and hygienic reasons, caulking has always been an indispensable part of tile tiling. From ordinary black and white cement, to modified cement-based caulk, to waterproof and anti-corrosion epoxy resin caulk, the development of caulking products has been quite perfect.
 
Around 2011, a unique domestic product gradually became the star of tile grouting, that is, the beauty of the joint. Although the controversy between sewing agent and caulk has always existed, with its unique enamel texture and color of adding sequins, sewing agent has been recognized by many users. Manufacturers often claim that the sewing agent has excellent waterproof and mildew resistance, because the sewing agent also uses epoxy resin as a raw material, but unlike the traditional epoxy caulk, the sewing agent is constructed with a glue gun, the texture is close to that of ceramic tiles, and more attention is paid to the decorative effect. Due to the consistency with the caulk audience, the traditional caulk brands have some opportunities in the field of beauty sewing agents, and JCDecaux is the representative of this type of brand.
 
JCDecaux is a wholly-owned subsidiary of Parex in China, a first-class special mortar brand, and has participated in the compilation of national standards for ceramic tile adhesives and cement-based waterproof coatings. In the 2018 Real Estate 500 Summit, JCDecaux was one of the top 10 paint suppliers. Since there is no such product as a sewing agent abroad, most foreign brands are absent from this market. Brands such as Mapei and Thunderty already have similar epoxy caulk products, while Henkel Black & Decker and Saint-Gobain Weber are not active in the field of sewing agents, and only the more local JCDecaux is at the forefront of this category and has launched many sewing agent products.
 
Unlike many brands that only launch one or two items, JCDecaux has a complete product line, ranging from entry-level to mid-to-high-quality. The price of the entry-level dazzling series ranges from 60~100 yuan, and the specific price is related to e-commerce activities and dealers, and it is a cost-effective product. The diamond series goes one step further, the biggest feature of this series is that the color selection space is large, a total of 24 colors are available, surpassing the vast majority of products on the market, and there are several uncommon soft light colors such as soft white and soft gray. Compared with traditional sewing agents, these products have a softer luster and a slightly more low-key style.
 
JCDecaux's current main upgraded sewing agent is the "Colored Porcelain" series, and the basic "Wall and Floor General" is priced at 129 yuan, which is better than the entry-level "Dazzling" in terms of toughness and delicacy. In addition, the special model for floor heating is also worth mentioning, and the biggest feature of this beauty sewing agent is that it has good temperature tolerance. The hardness of traditional sewing agents is relatively low, and some sewing agents may crack in the case of large temperature differences. In a room with floor heating, the probability of this happening is even higher, and the "colored porcelain" series of floor heating models are more reliable in this environment. At present, the price of the special model for floor heating is about 160 yuan, and the cost performance is also good.
