Is the sealant hard or soft when it dries?

When it is dry, it is usually hard.

The purpose of leaving cracks in ceramic tiles is to prevent porcelain from collapsing, because everyone knows that it expands with heat and contracts with cold. Now everyone has seen the caulking agent, especially the owners who buy the caulking agent have seen the slogans advertised by the merchants. Hard as porcelain, you can think about it. If the caulking agent is really as hard as ceramic tile, won't it collapse when it expands with heat and contracts with cold? It can be imagined that the sewing agent is not necessarily as hard as possible, but has good flexibility. It can be restored to its original shape after being pressed down, and this kind of sewing agent is a good sewing agent. Can the beauty agent be softened with a hair dryer?

1. When removing the beauty agent, since it has solidified, we must first find ways to soften the beauty agent, and the final removal will be much easier. It is completely feasible to soften the caulking agent with a hair dryer, and it should be set to high temperature, because the caulking agent will soften at high temperature. The power of the selected hair dryer is slightly higher, one is about 2 watts. After blowing for a period of time, this hot air hair dryer can soften the caulking agent, and then shovel it off with a shovel to speed up the construction.

2. However, when blowing the adhesive with a hair dryer, you must keep a certain distance from the ceramic tile, reaching 2 ~ 3cm, otherwise the ceramic tile or plate will be easily burnt out at high temperature.

3. In addition to using a hair dryer, there are also softeners on the market that can dissolve the sewing agent. Spraying in the cracks of ceramic tiles, waiting for a period of time, causing a chemical reaction, can soften the caulking agent, and then eradicate it later, with twice the result with half the effort. How to shovel the sewing agent again

1. If the types of sewing agents are different, the methods of eradication will be different. Among them, one-component caulking agent is water-based and its adhesion is generally not strong, so it is easier to shovel. As long as the gap position of ceramic tiles is scraped continuously with a utility knife, it can generally be easily eradicated.

2. The hardness of two-component sewing agent will be higher, and it will be more difficult to clean. If you want to clean, you need to use a two-kilowatt blower to continuously blow the gaps between tiles until the sealant becomes soft, and then use a shovel or a utility knife to clean the sealant.

3. If you want to clean the two-component sewing agent, you'd better use a more powerful hair dryer. If the power is too low, it is difficult to reach the temperature of softening and beautifying agent, and if the hair dryer is used for too long, it may damage the hair dryer. To avoid hot air burning, it is recommended to wear gloves.
