The problem of hollow floor tiles is still serious, so how to avoid it?
There are many problems that lead to the hollowing of floor tiles, one of which is very important, that is, sprinkling water on the brick surface after paving. Maybe you seldom or never see the maintenance of sprinkling water on the brick surface, but this maintenance is really necessary.
Today, the thick craftsman will talk about it.
Function of sprinkler maintenance on floor tile surface
The purpose of sprinkler maintenance is to avoid loosening and hollowing of floor tiles, and its functions mainly include the following two points:
1, in order to avoid the rapid evaporation of water in cement mortar, the hardening of cement needs to be carried out at a certain humidity, while the dry paving method commonly used in floor tile paving has less water in cement mortar itself. If the environment is dry and the temperature is high, the water in the cement mortar will evaporate rapidly, which will affect its bonding with the floor tile, and the direct consequence is that the floor tile is loose and empty. By sprinkling water on the surface of the floor tile, a certain amount of water can be added to keep the humidity of the ground and prevent the cement mortar from evaporating too fast.
2. It can cool cement mortar.
The hardening process of cement is an exothermic process. If the heat emitted in the process of cement hardening is not released in time and the temperature is too high, it is also harmful to cement hardening. The ultimate performance of this hazard is that the bonding strength of cement is not enough, which leads to the loosening and hollowing of floor tiles. Sprinkling water on the surface of floor tiles can cool cement mortar, especially in the case of high temperature in summer, the benefits are more obvious.
Problems needing attention in floor tile maintenance
The maintenance of floor tiles is relatively simple. Sprinkle water on the tile surface about 7 days after paving. However, there are several issues that should be noted as follows:
1. Don't pour water on the wall.
When sprinkling water to maintain floor tiles, be careful not to pour water into the wall. Because the wall will absorb water, if the wall is not completely dry, the putty layer may fall off or become moldy when scraping putty on the wall in the later period.
2. Don't use too much water.
As long as there is water on the surface of the floor tile, the water quantity of the floor tile can be maintained without running water. Because the floor of the living room is not waterproof, if there is too much water, there may be water seeping into a corner downstairs. This situation is quite common in practice. Therefore, in order to avoid the problem of water leakage, it can be used in a small amount and sprayed several times.
3, tile jointing before maintenance
Watering and curing of floor tiles must be carried out before jointing, and it is meaningless to water the floor tiles after jointing. Because water can't penetrate into cement mortar, premature jointing also has a certain influence on the heat dissipation of ceramic tiles.
