Why is it that today's tiles do not adhere well to cement and peel easily?

Increasing consumer demand for quality and aesthetics requires suppliers of  tiles to constantly improve, diversify designs and specialize in different use areas from a dry place. to wet places such as:  living room, bedroom, kitchen,  house bath… Meanwhile, the vast majority of construction methods for tiling are still in the traditional way, which is to use cement oil paste. So the question is why the cement paste is no longer compatible with today's ceramic tile technology? It is not difficult for us to see images of bricks peeling, cracking and falling in buildings, public works, and even in high-class apartments. There are many causes leading to brick problems in tiling; These can be mentioned as: arising from the texture of the tiling surface, construction methods, construction techniques, types of materials such as bricks, adhesives ... This article will mention one of the many reasons above, which is the type of construction material chosen for construction. It is easy to see that the brick trend changes very quickly and dramatically, but the construction method of gluing the wall and the floor stays the same.

 

Tiles peeling, why? Previously, ceramic tiles, also known as ceramic tiles , were very popular on the market, with simple designs, low features and small sizes like 30x30cm. And because ceramic tiles have many limitations, porcelain tiles were born and almost dominated the market. Porcelain tiles meet the most stringent requirements of consumers: from delicate patterns, to hardness, water absorption, scratch resistance; can even make very large bricks like 80x80cm or more than 1m… Along with this trend, the material for tiling porcelain tiles on walls and floors sànensures good adhesion, aesthetics and high durability for a beautiful house is a big problem. While, cement paste is no longer the solution due to its compatibility in terms of adhesion.

With a porous texture and many voids, ceramic tiles can be applied with cement oil. The oil can then penetrate the capillaries created by the pores of the ceramic tiles. Between them create a purely mechanical bond with each other for adhesion. However, with porcelain tiles with a solid structure and extremely low porosity, the cement paste does not have the opportunity to work. Imagine two surfaces of brick and oil lake touching each other without a solid anchor point, will "slip" each other sooner or later.
