Common problems parsing large tile

2016-07-22

First, ceramic tile hollowing

Take a small hammer to knock a piece of floor and wall tiles, by the sound to determine whether there is hollowing. If there is no hollowing sound more boring, if there hollowing, sound more crisp. In accordance with the relevant provisions of the acceptance of Beijing, local paving tiles hollowing not exceed 5% of the total.

CAUSE: tile hollowing causes are many common scenarios are:

1. Before paving tiles soaked enough time or too long.

2. paving, cement mixing mortar or cement mortar is not uniform ratio is not in place, resulting in too little cement brick can not stick to the wall.

3. tiling, craft workers not at home, did not make the tile and cement compaction or dense tiling will not, will cause the tile adhesion decreases. When the seasons change, larger temperature changes make these issues more prominent.

4. Currently lightweight wall, use of the riser pipe and wall insulation within the wall of the keel plus cement pressure plate method of making that first hit the keel layer and then with cement pressure plate closed. On this wall tiles, ceramic tiles since the self-important, easily deformed keel stress, displacement, cement pressure plate will therefore certain changes occur, with the evaporation of water, cement and other materials shrink tiles are also prone hollowing.

In order to reduce the likelihood of the occurrence of hollowing tile, usually have to hang in front of the tiling layer steel mesh or use a mortar interface agent, or ratio, to reduce the hollowing problems.

Treatment: If only one corner or the middle of a little hollowing, this is normal. If more than two corners or the middle of multiple tiles hollowing, even arched tiles, the wall is disengaged, it must require workers paving bricks pry resurfacing. And if more than 1/3 of the pavement area there hollowing, you need to put all the tiles Qiaodiao resurfacing.
Second, tile bagging, shedding

CAUSE: a construction team to cut corners, the ratio of cement and sand do not come standard; 2 process time discount, no sand cement mix, and also omitted after a good "Xing" of time, generally 3-4 minutes;. 3. workers after tiling without further compacting brick wall binding directly covered trouble; 4. more serious part of the original primary treatment is poor, the construction team did not do before tiling roughed; 5 glazed tiles soaked. not enough time.

Treatment: Experts said that as long as there are two reasons exist, the tile will inevitably fall off. In general, the paving is not dense, primary treatment is not good enough and soaked in water is the most common reason, you can use tile Adhesive glue tiles to fall off.

Third, the tiles crack

1, wall tile surface cracks large area

CAUSE: cracks in the wall because of subsidence caused mostly new room, the room is relatively old and even less, if the grass-roots produce settlement, will lead to the surface of the brick, wall paint cracking. Cui Tao, Beijing eras Decoration Engineering Branch manager, if several bricks appear regular or irregular cracks, the owners can be taken down to determine whether the grass-roots issues. Consistent If a good few tiles fracture direction, and runs through the room, the other rooms tiles did not change, there may be a house bottom surface of the base deformation, such as floor in cracking or deformation of the ground leveling layer cracking and other infrastructure leads tiles cracking.

Solution: Check the grass-roots change is serious, the worst case may affect the safety of buildings, is not serious will not affect the use, you can not control, keeping attention to grassroots change.

2, ceramic tile surface cracks

CAUSE: 1. The tile itself much inferior in quality may also lead to cracking or cracked case, but Cui Tao said that the current situation is more rare, "quality brick really very time, tensile too bad that there may be case. " 2. Paving not soaked before conservation, resulting in cracking brick by cement mortar tension occur. 3. waterproofing and other primary treatment is not in place, it can also cause cracking of the wall tiles.

Solution: If you do not cause hollowing, shedding, cracking tile mostly affects the appearance, if troublesome, can not control.
