How to repair the inorganic terrazzo crack?
Although the Inorganic Terrazzo stone itself has good crack resistance, but sometimes there will be accidents, such as man-made damage, building expansion, grassroots settlement, construction method, and other problems will lead to the damage of the inorganic stone.
However, there is no need to worry too much. In most cases, the cracking damage problem can be repaired. Here we introduce the repair method of inorganic terrazzo.
Step 1: Find out why
Finding out the cause is the most important step in repairing an inorganic terrazzo, because if you do not know the cause of the crack, then the crack will crack again, which will not only waste the cost but also waste a lot of time. We need to follow the following steps to find out:
1. Is it due to temperature?
2. Is it due to settling or shrinkage?
3. Is it caused by the construction method?
If the cause of the crack cannot be empirically determined, then the cracked area needs to be cut open to see if the underlying concrete is cracked, and if the concrete layer is fine, the repair can proceed directly.
Step 2: Ground repair
Measure the size of the damaged position;
Make parallel cutting according to the region block;
When cutting, pay attention to whether there are cracking symptoms around the damaged area;
According to the ratio, the master material and aggregate are evenly stirred and spread to the cut position;
Pour the material into the cut area, in order not to appear color difference, to clear the cutting position of the color and aggregate;
If the area is small, use a spatula to smooth it on the ground;
Wait 24 hours for the ground to cure, then prepare for sanding.
In fact, inorganic terrazzo repair is not difficult, experienced construction personnel can repair it in a very short time, if it is in a few months after the installation of cracks, then the possibility of restoration is very high, will not form an obvious color difference.
