After finishing the seams, if they are ugly, can they be wiped off? What should I do if the seams agent is too hard when scraping the glue?

This depends on what kind of caulking material you use. If the caulking is ugly after using a two-component caulking agent, you cannot easily wipe off the caulking agent on the surface. If you use ordinary caulking agent, which has low hardness and viscosity, and find it ugly before the caulking material dries, you can wipe it off with a wet towel or rag.

If the seams are ugly after finishing, can they be wiped off?

First, if you haven't done a good job of applying the caulking agent, wait for the caulking agent to dry, then use a sharp paper cutter to gently cut the two sides of the tile gap, and then gently tear it upwards a little bit. It is best to cut and tear a section at a time, so that it is not easy to break and it can be torn more cleanly. After tearing, use a small spatula to clean the uncleaned parts, and then vacuum it up.

If you are using a caulking agent that is a dry powder like white cement mixed with water into a paste, use a paper cutter or a small awl spatula to scrape all the fillers in the tile joints into powder, then use a vacuum cleaner to clean up the powder, and then make the beautiful joints you like.

What to do if the caulking agent is too hard when scraping glue

Of course it is better to be hard after curing. Otherwise, it is better to use a single-component caulking agent, which is cheaper.

It is generally recommended to use a two-component real porcelain glue with a certain toughness for the caulking agent used for floor tiles. However, it does not mean that it is soft. In fact, it is still very hard on the surface, but it has a certain flexibility compared to ceramic tiles. When the ceramic tiles shrink and expand due to the influence of the environment, they will not collapse or crack. At the same time, it has good hardness and is not easily scratched. It can keep the surface smooth and flat, and it is not easy for dust to be embedded and discolor and become dirty. This is toughness under the premise of being hard. Don't mistake it for soft. The caulking agents of brands such as Weigang and Baoshijie on the market are all of this type.

The best steps for seaming

The first step is to cut the nozzle of the hose as close to the size of the tile gap as possible, so that when applying glue, the glue can just fill the gap without overflowing too much.

The second step is to fill the gap as much as possible when applying the caulking agent. The speed should not be too fast. If it is too fast, the caulking agent will only form a layer of film on the surface of the gap, but the inside will not be filled.

The third step is to use the tool provided when you buy the caulking agent to firmly press the caulking agent in the gap. This step is particularly important. Most of the problems mentioned by the original poster are caused by not doing this step well. Be sure to press as hard as possible, and don't be afraid of hurting the tiles. The harder you press, the more obvious the caulking agent on the edge will separate from the caulking agent in the tile gap. Finally, it will be easier to scrape off the excess caulking agent.

The fourth step is to shovel. Depending on the weather temperature, wait 24 to 48 hours, and wait until the grout is completely dry before shoveling. If the third step is done well, this step is very easy. As long as there is a corner that is lifted up, you can pull up a large piece with your hands. If the third step is not done well, you will either be unable to shovel, or the grout in the tile joints will be pulled up with a shovel.
