The traditional method of pasting tiles or stone is to adopt the on-site preparation, mixing cement, sand, 108 glue and water according to a certain proportion and then pasting. Since the water retention of mortar of this kind is low, tiles should be soaked and wetted in water beforehand, and then put mortar onto the back of tiles. Also, due to poor flexibility of mortar, the mortar needs thick layers of coating, generally with a thickness of about 10mm. Put the tiles coated with mortar onto the pre-wetted wall surface, and then tap the tiles in order to ensure the flatness of tile surface consistent. In this traditional approach, if the coating of cement mortar is uneven, tiles are prone to hollowing and shedding. Since the adhesion of ordinary cement mortar is poor, large tiles or stone coated onto the mortar layer must be mechanically fixed or reinforced. And because this ordinary cement mortar does not have slip resistance, tiles must be pasted from the bottom and locators should be used between tiles to ensure the pasted tiles smooth vertical and horizontal, as well as surface neat. Thus, it can be seen that this method is very time-consuming and inefficient, with large consumption of materials and high requirements for manual construction techniques. Due to restrictions of their own performance of such materials, the construction quality is difficult to guarantee, and such quality problems as tile hollowing and shedding often occur.
With the development of modern construction technique, the use of this traditional mortar is faced with many restrictions. Currently in most industrialized countries, the use technology of thin-layer mortar has replaced the construction method of the thick-layer mortar. Such thin-layer mortar is a mixture of cement, aggregates, polymers, special additives and fillers, called tile adhesive mortar, non-toxic, and belonging to green products. By using cellulose ethers and redispersible latex powder for modification, it has greatly improved the water retention, flexibility and bonding properties of mortar. In construction, it only needs to mix the tile adhesive mortar and water evenly, to put the mortar smeared large-area onto the substrate surface to be pasted with the use of serrated trowel to form a uniform adhesive mortar layer with a thickness of 3-4mm, and then just to slightly rotate the tile and press into the mortar layer. No fixation is needed between tiles, and tiles will not slide either. Furthermore, pasting from top to bottom can be achieved. Neither the tile nor the substrate needs to be soaked or wetted beforehand, reducing the process and keeping the construction environment clean and tidy. Therefore, compared with the thick-layer mortar technology, the thin-layer mortar technology is more cost-effective, uses fewer materials, has a wider range of applications, and is simpler, faster and safer to operate.
