Two ways to deeply analyze cracks in tiles

Tiles have always been a very important aspect in the entire home renovation, not only the proportion of the cost it occupies, but also the most contacted building materials products in daily life at home, so the choice of tiles Good or bad, it is very important whether construction is performed according to the specification during construction. Tiles are also involved in more aspects, mainly in two aspects, one is the problem of leaving the size of the joint, the second is the problem of jointing. From the above two aspects, we will introduce the problem of gap handling in the re-decoration construction of tiles.

Ethino tiles

One, left seam

Because the brick is straight or trimmed, the brick surface and the side surface are at right angles of 90 degrees, so when two pieces are tiled together, the gap between the brick and the brick is very small, so that due to the small gap, the overall Sexuality is stronger, so the friends who pursue the effect let the workers make a seamless paving. Not only does this approach fail to achieve very good results, it is also a very wrong practice.

1、The reasons why tiles cannot be tiled seamlessly:

1) Tiles have errors

As we all know, any product can not be produced in the same size, weight, etc., as long as it is consistent with the relevant standards, we can call it an error, for the same batch of tiles of the same model of the product There may be deviations in length, straightness, straightness, etc., and there is no such thing as a tile with no error in these areas.

2) There will be some errors in the construction process

In the construction process, apart from non-standard construction methods, workers will have some errors in the collage.

3) Effect of hot rising and shrinking on tiles

The most important point is: any object has a thermal barrier shrinkage, tiles are no exception. If the gap is too small, the ability of the ceramic tile to adapt to the environment will be deteriorated. Due to the temperature change, the tile will be broken and the normal service life of the tile will be reduced.

2, the decoration of commonly used tiles joints suggested

1) When laying tiles, such as seamless bricks, and polished tiles, the size of the joints should generally be between 1 and 1.5 mm and not less than 1 mm. Gas nails can be used as a reference.

2) Archaic bricks generally have a slightly wider seam, typically 3–5mm.

3) The outer wall of the balcony culture bricks generally leave about 5mm.

Second, pointing

Tiles in the paving process, you must leave the seam, the size of the left seam depends on the specific product, in general, the tiles need to be caulking after the paving, the following will introduce the material used for hooking and hook The timing of the problem.

1) Stitching material

The materials used for the conventional jointing are cement, caulking agent, putty powder and so on. Among these types of materials, putty powder and white cement are more traditionally used materials. Nowadays, the use of cement bricks as the jointing material is mainly used for balcony culture bricks. For example, paving balcony bricks directly use ordinary cement mortar. can.

Putty powder, white cement waterproof performance, resistance to scrubbing performance is worse, now, the family decoration process, in the kitchen floor, the living room floor tile joints generally do not use, now basically choose a professional tile caulking Agent (also known as caulking agent).

2) The type and selection of seaming agent

Grafting agent is mainly divided into sand and sand-free in the market. In general, light-walled tiles and vitrified tiles are suitable for use without sand, and paving matt bricks and antique tiles are suitable for sand.

There are two ways to choose the color of the seaming agent. One is the proximity method, the choice of the seaming agent is similar to the color of the tile, and the second is the contrast method. The color and the tile color form a strong contrast.

3) Selection of the sewing time

Generally, the time selected is 24 hours after the tiling, that is, after the tile is solidified, the time of the jointing is too early, which will affect the tile that is tiled, resulting in uneven or loose. In addition, before the jointing, you need to clean the dust in the cracks in the tiles.
