First, despise waterproofing
1, wrong consequences
Waterproofing is a very important home improvement project. It is generally assigned to bricklayer construction. Before the formal paving, the wall and floor of the bathroom, kitchen, etc. need to be waterproof. However, it is considered that the waterproof layer made by the developer is qualified, and there is no need for waterproofing in home improvement; the quality of the waterproof material used is poor; only some key areas do waterproofing is a common mistake. Waterproofing works are not done well. Once leaked, the furniture and walls will be mildewed, while the damage will be destroyed and the neighborhood will be damaged.
2, the correct approach
To avoid the problems of moisture and leakage, it is necessary to understand the mistakes of waterproofing and to supervise good quality.
Second, tiles are not treated with water
1, wrong consequences
When laying tiles, the fit of the tile to the wall is greater than the gravity generated by the tile itself. Because the ceramic tile itself has many small holes, strong water absorption capacity, dry tiles will dry the moisture of the cement, making it less fit, hollowing and falling off easily after laying.
2, the correct approach
In order to ensure that the tile fully absorbs water, it is best to soak in advance, suck enough water, and then remove it. After the surface is dried, it must be soaked twice and used for fishing.
Third, tile without leaving any gaps
1, wrong consequences
When laying tiles, many people want to achieve a small gap. However, the thermal expansion and contraction of ceramic tile requires tile joints to leave seams. If the gap is too small, the ceramic tile's ability to adapt to the environment will deteriorate. Due to the temperature change, the tiles will be broken and the normal service life of the tiles will be reduced.
2, the correct approach
Tiles need to leave gaps, the size of the seams left by bricks should generally be about 1-1.5mm, not less than 1mm; special effects can also widen the gap, such as 5mm and so on.
Fourth, casual mixing of wall tiles
1, wrong consequences
In the bricklayer construction process, one mistake that is easy to make is to mix and match tiles and tiles. Need to know the physical and chemical properties of different tiles are not the same, such as wall tiles and the water absorption rate of the tiles are not the same, high wall tiles, floor tiles, the two are not the same bending strength, and different space parts There are differences in the performance requirements of the tiles.
2, the correct approach
In the construction, it is best to operate according to the packing box or the manufacturer's statement, taking into account the performance of the tiles. In general, floor tiles can be used as wall tiles, but ordinary glazed floor tiles cannot be used as wall tiles. Exterior wall tiles can be used as inner wall tiles, but inner wall tiles cannot be used as exterior wall tiles.
