What are the causes of the hollowing of the tiles in the construction steps of the tile hollow drum grouting injector?
After the new decoration is used for a period of time, many owners will find that there are empty tiles in the tiled area. At this time, the master must rework the shop and the amount of work is quite large and the cost is not low. Very annoyed, then Xiaobian took everyone to look at the construction steps of the tile hollow drum grouting syringe . It can easily deal with the empty tile to bring magical effect.
Construction steps of tile hollow drum grouting syringe :
1, empty parts statistics:
Before the construction, tap the wall or floor with a small hammer to perform detailed statistics, and then clearly mark the position of the empty drum.
2, drilling positioning:
It is very important to position and position the holes, which will directly affect the effect of grouting. It is recommended that the masters with rich construction experience should design and position each empty drilling hole.
3, permeability test:
Before using the high-pressure pump for grouting, first test the permeability of the borehole to ensure the perforation of the borehole and smooth the grouting.
4, crack closure:
Before the grouting, it is also necessary to close the gaps between the board seams and the tiles. In this way, the slurry will not flow out when the grouting pressure is applied.
5, pressurized grouting:
Using a special grouting nozzle, together with low-pressure or high-pressure grouting equipment, the grouting resin is evenly pressed into the pulp hole.
6, check the fullness:
When grouting, it is recommended to use a small hammer to tap and check the direction and fullness of the slurry.
7, grouting resin has high curing strength and is difficult to clean. It is necessary to clean spilled resin at any time. Wipe the cloth with ethanol.
8. After the hollow drum grouting syringe is used for treatment, the hardening time of the grouting resin needs about two days. In this case, it must not be stomped.
What causes the hollowing of the tiles :
1, caused by the construction process
Wet tile tiles are prone to hollowing. Due to wet paving, the moisture content of the cement mortar is high, water penetrates into the base layer, and many voids are formed after drying. As a result, the floor tile and the base layer cannot be fully bonded and empty drum phenomenon occurs.
2, construction technology issues
The grass-roots level has not been thoroughly cleaned and sand grains have been left behind. The cement mortar has not been integrated with the grass-roots layer. As a result, empty drums have appeared for a long time.
3, cut corners
In order to save time and material, the construction only applies sand and ash to the four corners of the tile, and then spreads it. Because there is no sand in the middle of the tiles, it will naturally cause a kick from a long time.
Summary of the article: The above is for everyone to introduce the construction steps of the tile hollow drum grout syringe and the reasons for the cause of tile hollowing. I believe we have a certain understanding after reading, if you need to learn more about the later Welcome to follow this site.
