One.Tile adhesiveWhat is it?
Mortar is a modern renovation material used for adhering tiles, mosaic tiles, and floor tiles. The main advantages of mortar include strong adhesion for tiles, waterproofing and moisture resistance, and resistance to aging. It is commonly used for exterior wall renovations and is easy to apply, requiring no pre-soaking of the tiles. only a thin layer of mortar is needed when adhering tiles, which also saves space compared to using cement.
Compared to cement, tile adhesive is significantly more expensive. The market for tile adhesive is also fragmented, making it difficult to distinguish between genuine and inferior products. Poor-quality tile adhesive can also release harmful gases, posing a threat to human health and exhibiting relatively poor environmental performance.
Two. Is it good to apply tiles directly onto cement?
Cement is a common construction material. Due to the mechanical interlocking force created when cement hardens and interacts with other materials, it is frequently used for building walls and laying bricks.
Disadvantages include: large application thickness, poor adhesion, increased material usage and the tendency to form voids, leading to issues such as tile detachment or peeling due to thermal expansion and contraction of concrete after several years of use.
Three. Which is better, tile adhesive or cement?
1、Regarding construction aspects
Applying tiles with cement is a complex process that requires steps such as wet wall preparation, brick soaking, and support installation. This process is not only inefficient but also results in poor tile adhesion (prone to issues like blistering and detachment). Tile adhesive can eliminate these complex steps, making it a more practical and efficient solution.
2、Adhesion of materials
Currently, the quality of tiles has improved significantly, resulting in lower water absorption rates even for wall tiles. This means that traditional cement-based mortar is no longer suitable for tile installation. Furthermore, tiles are becoming larger, making it easier to bond them with tile adhesives. Unlike cement-based mortar, tile adhesives are less susceptible to expansion and contraction due to temperature and humidity fluctuations, which can lead to tile detachment.
3. Aesthetics
The ratio of materials used for tile adhesive is reasonable and uniform, resulting in consistent shrinkage during application. This ensures that the tiles are applied smoothly and completely, preventing air pockets and detachment.
