The beautiful seams of tiles can destroy everything in a few millimeters!

Don’t look at the gap between the tiles is only a few millimeters. If they are not done well, these millimeters may become a fly that “destroys a pot of soup”, destroying the appearance of the entire floor and the quality of the tiles. If you fill the gap casually at the beginning, it will take a long time to look up, but you wo n’t see your head down. The blackened tile seams are always reminding you. It ’s ugly.

Today we will talk about those things about the cracks in the tiles:

1. I filled the gap, but it turned black. What happened?

2. Can Misumi come by myself?

3. What should I do to make the color of the gap between the tiles and the similarity of the tiles a little higher?

The material is not selected correctly, no wonder the seam turns black

Speaking of caulks, it really has to be said. Jointing agent, beautiful joint agent, porcelain joint agent, real porcelain glue, white cement … There are various scientific names, and the difficulty is comparable to distinguishing who is Zhang Xinyu, Zhang Yuxi, Zhang Yiyi, Zhang Yixin, Zhang Yixing … Regret your life.

White cement

White cement is a relatively early joint filling material, which is mainly used to hook the gaps of white porcelain. Generally it is not used for walls because the strength is not high.

However, due to its high whiteness and bright color, it is generally used more as a variety of building decoration materials. Of course, many small partners will choose to use white cement to repair the wall.


Can be understood as an upgraded version of white cement, because it is based on white cement, and then adds a small amount of inorganic pigments, polymers and traces of antibacterial agent to form a dry powdery material.

Compared with white cement, although it has stronger adhesion and anti-cracking performance, it is not resistant to water and dirt. Therefore, it was only when the home was filled with cracks, but it turned black.

Beauty sewing agent

The upgraded version of the joint sealer has high color value and rich and bright colors, which can be used with tiles of various colors. The appearance of the beauty seam is easy to wipe and clean when it is dirty. What’s more important is that it is waterproof, moisture-proof, oil-resistant and stain-proof, which can effectively avoid the embarrassing situation of “crevices turning black.”

However, one of the disadvantages of beauty joints is that they tend to collapse after curing, so they can only be filled in form, not fully. It is not suitable for use in bathrooms and kitchens, which are often exposed to water.

Porcelain jointing agent (true porcelain)

It is an upgraded version of the beauty joint. It is wear-resistant, water-resistant, stain-resistant, and mildew-proof. It can make tiles, wash basins, toilets, and other gaps.

Construction began:

1. clear the gap

Use a small awl or a spatula to scrape the dirt in the gaps between the tiles, and then use a bristle brush to leave a gap depth of 1.5 mm.

If you want to clean the gap efficiently, you can use a small car vacuum cleaner to clean the gap when scraping the gap. The effect is very ideal.

2. Textured paper

Stick the texture paper horizontally and vertically along the edge of the tile. When you paste it, the paper should overlap the edge of the tile as much as possible. It can be less than a bit, but you should not stick it to the seam beyond the edge of the tile. There will be holes in the paper.

3. Caulking

Insert the rubber tube in the beautifying agent and install it in the glue gun together. Squeeze the beautifying agent directly along the gap. The important point is to pay even force.

After filling the gaps, use a spatula or ice cream stick to smooth it while the beauty agent is still flowing (note: do not wait until the whole surface is filled).

Two lessons were summarized during this process:

First make the wall, then the ground, horizontal to vertical, vertical to vertical (that is, only do one direction at a time, or horizontal, or vertical, wait for one direction to dry and then do the other direction, otherwise the intersection is easy to stick flowers, Don’t do it crosswise)

In terms of the amount of glue to squeeze, it is still recommended to squeeze as full as possible, more is better than less, otherwise when it is smoothed out, holes or unevenness are likely to occur.

4.Tear textured paper

After smoothing, immediately tear off the sewing paper. If it is not timely, either the textured paper cannot be removed, the gap is rough, or the dried sewing agent is taken out and needs to be filled again.

However, there are also those that can be directly applied with no need for textured paper, but it is limited to polished tiles, polished glazed tiles, and ceramic tiles with smooth surface. Beauty sewing agent.

How does the color of the tile gap match the tile better?

To sum up briefly, there are three better matching methods:

Light tile with dark grout

The most intuitive feeling of this combination is bright and concise, and the biggest benefit is that you no longer have to worry about the white grout getting dirty alone!

Light-colored grout for dark tiles highlights texture

Dark tiles with light grouts are the easiest way to highlight texture. Light-colored gaps make the horizontal and vertical arrangement of dark tiles clearly visible.

The same color system is more natural

This combination is suitable for those who choose antique bricks or complex tile patterns and don’t want to highlight the gap.
