What causes uneven scraping of tile adhesive?

It may be that the thickness of the tile adhesive is not enough, the mixing is uneven, the tile adhesive coating is not full, we must ensure that the tile adhesive is stirred evenly before it can be used. Although tile adhesive has a tendency to replace traditional cement with its excellent performance, if the construction details are not controlled, the performance of tile adhesive will be greatly weakened, and the mixing is not sufficient or uneven, and the proportion of water added is wrong. The temperature was outside 5 40 at the time of construction, and no protective measures were taken.

Before the tile adhesive is completely dried or damaged by external factors during curing, such as rain and man-made damage. Other reasons. Question 2:

Tile adhesive is still not strong and soft after 2 to 3 days after construction. Reason: The thickness of the tile adhesive scraping is too large to harden normally.

The water absorption of the base surface or the tile itself is too low. The tile size is too large. The outside temperature is too low, no protective measures are taken, and the hardening speed is slow

How long does cement-based tile adhesive take to dry and solidify after pasting. Reason: Usually cement-based adhesives take 24 hours to cure.

The period of low temperature or poor ventilation will be relatively prolonged. Question 4; Small cracks will appear in the glazed tiles after pasting. Reason:

The glaze of the brick is too thin. The tile adhesive used is rigid, which leads to greater shrinkage after drying.

Reason: There are no seams between the tiles during construction. Cracks are caused by thermal expansion and contraction of ceramic tiles.

Problem 6: The tile cracks after pasting for a period of time. Reason:

Base surface settlement or telescopic displacement. Deformed after compression. The tiles themselves cause cracking.

Tile paste is not left or the gap is insufficient. The thickness of the tile adhesive is not enough. Question 7:

There is a hollowing problem with tiles. Reason: Unqualified base surface treatment.

If the layer is uneven, the base surface should be leveled first; The thickness of the tile adhesive is not enough, and the coating of the tile adhesive is not full; Toothed scraper residue dry tile adhesive; The scraping speed is too fast, and the scraping speed needs to be slowed down; The tile adhesive is unevenly stirred, and there are dust particles, which affects the scraping of the tile adhesive, so it is necessary to ensure that the tile adhesive can be fully stirred before use. Tile adhesive is mixed with cement, sand, etc. Tile adhesive is already a good ratio of products, no need to add other things, if added will destroy the ratio of the product, the quality can not be guaranteed, tiling is prone to hollowing, falling off and other problems.

Place the tile glue on the ground and stir with a shovel. First of all, putting it on the ground will lead to the loss of the effective chemical components of tile adhesive; Secondly, it is impossible to mix evenly with a shovel, and the proportion of water added to manual stirring is difficult to be accurate, which changes the ratio of materials and leads to a decrease in adhesion.

The one-time gluing area is too large, and the surface of the glue is dry and solid, resulting in uneven scraping. Use time process, and then add water to stir and use: the active ingredient of tile adhesive has undergone a chemical reaction, and adding water will only change the operation performance, which will lead to insufficient bonding strength in the later stage; Tile adhesive should be used with stirring, the use time should be controlled within 2 hours, and it should be discarded after drying.

Put the tile adhesive in a bucket and soak it with water: the construction master still uses the method of soaking cement to soak the tile adhesive, which is wrong, which will cause the tile adhesive to have no adhesive strength, and cause the tile to fall off in the later stage. The correct splitting and scraping process should be:

First of all, on the horizontal base surface, use the tooth scraper to evenly form a strip tooth layout of the tile glue. Then, pick up the tile and press it downwards and rub it up and down evenly. We can clearly see through the glass that the tile adhesive is very evenly distributed under the glass.

If the floor tiles are uneven with adhesive tiles, you can try the following methods to return to the bridge:

1.Re-paste: If the tiles are not dry or the glue is insufficient, it may cause the tiles to be uneven. At this point, the uneven scales or bricks can be removed and re-paved.

2.Adjust the height difference: If the floor tiles have been fixed, but there is a height difference, you can use a grinder, electric hammer and other tools to adjust it. First, use a grinder to smooth out the high parts, and then use an electric hammer to thicken the low parts until the surface of the floor tiles is flat.

3.Use caulk: If the gaps between the floor tiles are uneven, they can be filled with caulk. Apply caulk to the gaps, then use a spatula to smooth them out and wait for them to dry.

4.Use a Tile Grader: A Tile Grader is a tool that can help adjust the height difference of the floor tiles. Place the tile grader on the uneven floor tiles and press the grader until the surface of the floor tiles is flat.

Please note that when carrying out repairs and disposals, the appropriate method is selected on a case-by-case basis and the relevant safety norms and standards are observed. If you are not sure how to proceed, please seek professional technical support or service.

1. Trample on the condition that the tile is not dry after pasting, and the tile will sink due to the disturbance of the antcheon. You can ask the decorator to help you gently beat it back to leveling. If there is a lot of sagging, it can be removed and repaired again.

2. If the tiles are completely solidified on the ground, they can only be broken and removed with tools, then filled with cement and replaced with new floor tiles.

3. In the case of large-scale unevenness, it is difficult to correct the local slowing down and making up for the envy of the object, so it can only be restarted. Be sure to find a professional floor tile master, the effect of the paste is really different, whether it is durability and aesthetics.
