When it comes to the words "falling off exterior wall tiles", people will think of the incident of falling off exterior wall tiles and hurting people. This situation is not uncommon. So, what are the solutions to the problem of exterior wall tiles falling off? So let’s take a look at today’s topic: What are the solutions for dealing with falling off exterior wall tiles?
1. Reasons why exterior wall tiles fall off
1. External reasons
Exterior walls have been exposed to wind and sun for many years, and tiles are prone to aging, cracking, hollowing and falling off. This is an objective factor that cannot be changed.
2. The tile itself
(1). The quality of ceramic tiles on the market now varies from good to bad. The state stipulates that the water absorption rate of ceramic tiles shall not exceed 18%. However, the water absorption rate of many ceramic tiles is much greater than this standard. The higher the water absorption rate of ceramic tiles, the easier it is to cause swelling and cracking situation.
(2) The larger the size of the ceramic tile, the greater the weight. The greater the weight, the easier it is to cause falling off.
2. What are the solutions for peeling off exterior wall tiles
1. Clean the base surface of the area where the wall tiles have fallen off. At this time, you can use a wire brush to polish the floating sand and clean it to a solid part.
2. Spray water on the base surface of the treatment area again, use a waterproof sealant to smooth and compact it, and then proceed to the next step of construction after the curing reaches the strength.
3. Re-apply the polymer waterproof mortar coating. At this time, the integrity of the waterproof layer will be in this range. Before the coating is applied, it is still necessary to ensure that the base layer is moist to ensure that no water is lost during the reaction and curing process of the coating film.
4. After the coating film is completely cured and reaches strength, the exterior wall tiles need to be pasted again. The wall tiles should be moistened by sprinkling water before pasting, and moistened and cured after pasting.
3. Things to note when constructing exterior wall tiles
1. When the weather is hot, early-strength cement cannot be used.
2. The bonding layer of cement slurry must be painted evenly, and the painting time cannot be too long, otherwise it will dry and harden, resulting in hollowing.
3. The mortar must be dry and hard, and the best thickness should be controlled at about 2~3cm.
When laying ceramic tiles, first clean the floating dust on the ceramic tiles, then water them to moisten them to ensure good adhesion.
4. If only the tiles fall off, the mortar does not. You can clean the mortar on the bricks, then add an appropriate amount of cement to the special glue and stir it into a paste. Then apply a thin layer to the back of the tile and finally lay the tile.
5. If the tiles and mortar fall off at the same time. First, make some small pits on the wall where the tiles have fallen off. Then add special glue and mortar to re-attach it. After pressing it, wait until the mortar is basically hardened.
So after reading the above content, you will find that the reason why the exterior wall tiles fall off is not only the tiles themselves, but also related to external factors.
