What are the disadvantages of using sewing agent?

The caulking agent is a new type of caulking product and an upgraded product of the caulking agent for building materials. Consists of high molecular polymer and high-grade pigment. Solves the problem that the traditional caulking agent is easy to get dirty and crack. After use, it can make the tiles not dirty and black, waterproof and antifouling, even if they are dirty, they will be clean as soon as they are wiped. While understanding its advantages, let's talk about its disadvantages. The caulking agent is a new type of caulking product and an upgraded product of the caulking agent for building materials.

What are the disadvantages of sewing agent?

1, construction defects

Although some videos prove that the construction is very simple, when the construction is finished, you will find that scraggy has shortcomings and can't be wiped with anything, which will be even more ugly. It is the intersection of two seams, which is difficult to level off.

2. Appearance defects

Because the caulking agent is only a variant of one-component acrylic sealant, its wear resistance is very poor, and it can only be much lower than that of ceramic tiles when priming, and it will not be rubbed. But the disadvantage of doing so is that it is easy to hide evil people and shelter evil people. Moreover, for microcrystalline stone, polished glazed tile and vitrified brick, its concave surface makes feet feel uncomfortable. Especially some tiny cracks, such as 1mm or so, can't adhere to the surface.

3. Performance defects

Insufficient adhesion, uneven tiles, when the four seasons are alternately looking for shrinkage, the facade of the gap between sealant and tiles is easy to crack, which is mostly manifested as peeling and peeling of sealant. Because of the nature of the sewing agent, it can't be waterproof for a long time, and it will age quickly in the environment where it is easy to contact water, such as bathroom and kitchen. Poor wear resistance. If it is tested according to the standard of ceramic tile sealant, it will be ground with a wear tester and white corundum. Compressive strength, flexural strength and shrinkage can't pass these four indexes, only water absorption can. Therefore, it can only be called beauty sealant, which cannot be counted in the category of tile sealant, and there is no national standard.

4, the service life is short

At present, most domestic ceramic tile joints use caulking agent or jointing agent. Although economical and practical, with the progress of science and technology, caulking agent has entered people's lives. However, the common caulking agent on the market has low technical content and short service life, about three or two years. Type ⅱ caulking agent is more cost-effective, which makes up for the deficiency of type ⅰ (all the same industries in China are type ⅰ). Unique formula, rich colors, flexible collocation and antibacterial ingredients.

The caulking agent has entered people's lives and has been recognized by everyone. It is a kind of building material tailored to solve the problem of dirty and black tiles. The common caulking agent on the market is not high in technical content, and one of its characteristics is to make the cracks of ceramic tiles never dirty or black!
