In the initial stage of the construction of ceramic tiles, we have experienced many events that affected the beauty of the whole building due to pasting and caulking auxiliary materials, which confirmed that Dingcheng must have its own brand of auxiliary materials to complete each project elaborately, perfectly and with high quality. In Shanghai Tongji University and Zhejiang University Laboratory and the company jointly developed, Dingcheng brand special clay brick binder jcta-300, caulking agent jcta-360 came out, Dingcheng comprehensive strength has been comprehensively improved. Because of this, strategic partners have also given high praise and encouraging praise.

Dingcheng brand special clay brick binder jcta-300 is a new type of machine-free binder in China. The product is specially developed to prevent the spreading of alkali in the paving of clay split brick. It has the characteristics of low alkalinity, mildew resistance, water resistance, freeze-thaw resistance, high bonding strength, good aging resistance and convenient construction.

Jcta-360 special caulking agent is a kind of solid powder. Can be added with a variety of colors, mainly used for a variety of internal and external walls, floor tile caulking. The width and thickness of caulking can be selected by users. In winter, jcta-360 caulking agent can prevent water from seeping into the wall and prevent cracks. In addition, the use of caulking agent can also reduce the precipitation of free calcium in cement mortar without affecting the appearance of decorative tiles. According to the test of Shanghai Institute of building science, its performance has reached and surpassed the technical indexes of "ARDEX" in Germany and "ncobond-c.t300" in Britain, and reached the advanced level of similar products in China. It is recognized by many real estate developers and listed companies as the most ideal material for pasting and caulking clay split brick.

Construction method


※ The construction wall should be wet (dry outside and wet inside) and keep a certain flatness. The uneven or extremely rough parts should be leveled with cement mortar and other materials.

※ The base course must be cleaned of floating ash, oil, wax, etc., so as not to affect the adhesion.


※ This product can be adjusted into thick paste with water when used. It can be moved within 5-20 minutes after gluing brick, which is convenient for correction. The water cement ratio is about 1:4, and the adhesive can be used up within 5-6 hours (20 ℃)


※ Apply the mixed adhesive on the back of the pasted brick, and then press firmly until it is flat. Tile or perforated brick should be soaked before use, paste marble, mosaic and paper tile should be a thin (2-3mm) adhesive layer.


※ The solidification time varies from one factor to another (high temperature and fast solidification, low temperature solidification slow) and initial hardening for 6-7 hours (20 ℃), and complete hardening for about 17 hours.


※ During shipment and storage, the product should be protected from rain, moisture and stored for 6 months.


※ The actual consumption is different due to different materials. Generally, it is about 3-4kg per square meter, and the thickness of adhesive is about 2-3mm. It takes about 6 kg to stick mosaic and paper layout tiles.



matters needing attention:

The adhesive is not suitable for paint, plastic, wood or metal surfaces.
