How to repair tile hollowing and formulate solutions

Ceramic tile hollowing is one of the common problems in home decoration, which not only affects the appearance, but also may cause more serious damage. So, how to effectively repair tile hollowing? This article will provide you with detailed steps and practical suggestions to help you easily solve this problem.

1、 Causes of empty drum

Before repair, understanding the cause of the empty drum is crucial to prevent the same problem in the future. Common reasons include insufficient wetting of ceramic tiles when pasting, improper cement mortar ratio, and incomplete cleaning of the back of ceramic tiles.

two Construction steps of hollow microporous grouting treatment technology:

1. Statistics of empty drum parts:

Before construction, make a comprehensive and detailed statistics on the hollowing of the ground and wall on the site, knock with a small hammer, and mark the hollowing parts on the drawings.

2. Drilling positioning:

The layout of hole location is very critical, and the selection of hole location has a great impact on the grouting effect. It is necessary for experienced construction personnel to design and locate the location of each empty hole.

3. Permeability test:

Before using the high-pressure grouting machine for grouting, the permeability test shall be carried out on the borehole to ensure the permeability of the borehole and lay the foundation for the smooth grouting.

4. Crack sealing and installation of grouting nozzle:

In order to ensure that the grout does not flow out when grouting is pressurized, the cracks shall be closed before grouting and the grouting nozzle shall be installed.

5. Pressurized grouting:

Use special high-pressure grouting machine or low-pressure grouting machine to Grouting resin Evenly press into the grouting hole.

6. Check plumpness:

Check and judge the flow direction and fullness of grout by knocking with a small hammer while grouting.

7. Cleaning and patching:

Since the grouting resin has high strength after curing and is difficult to clean, the spilled resin should be cleaned at any time during grouting and can be wiped with a rag dipped with ethanol. For the treatment of stone and face brick, in order to ensure the bonding of hollow stone and face brick with the wall, after the grouting effect is determined, it can be loaded, supported or anchored with stainless steel nails. After the resin is solidified, the grouting nozzle can be removed and the grouting hole can be repaired.

3、 Measures to prevent hollowing

1. Ceramic tile pretreatment : The back of the tiles should be cleaned and soaked with water until no bubbles appear to ensure full wetting.
2. Base treatment : The base course shall be solid, flat, dry and free of oil stain, and the interface agent can be applied if necessary.
3. Construction skills : The tiles shall be fixed by tapping gently when laying to ensure that the mortar is full and even.
