1. Repair, sew and repair holes.
This is the most common treatment. Clean up the dust and sundries at the crack first, then soak the soft gypsum and gypsum powder in water, and then smear them on the crack. After the gypsum is dried, the surface is trimmed and leveled with sandpaper.
Step 2: Strengthen treatment
If the cracks on the wall surface are found to be serious, you can choose to reinforce the wall surface. You can open two small holes at both ends of the wall, then insert nails or steel bars into the holes, and then fill them with cement mortar or other suitable materials. This can strengthen the bearing capacity of the wall and make it stronger.
3. Partial renovation
If the cracks are large or exist for a long time, the cracks may have damaged the internal structure and need local reconstruction. When necessary, some walls can be removed for repair, and then plastered or tiled again.
No matter which method is adopted, we should pay attention to ensuring the stability of the wall and not destroying the structure of other parts. In addition, in order to avoid cracks on the wall again, it is suggested to choose high-quality materials and carry out reasonable construction to ensure the flatness and seismic performance of the wall.
