What’s the traditional way of pasting tiles?And what are the weakness?

- Jan 10, 2018 -

The traditional way to paste ceramic tile or stone is to use the site preparation,mix cement,sand 108 glue and water together,and then paste.Due to the low water retention of this type of mortar,the brick should be soaked in water in advance,and the mortar will be placed behind the tile.In addition,due to the poor elasticity of mortar,the mortar shall be coated with thick layers,generally about 10 mm thick.Apply plaster to the pre-wet wall and then use tile to ensure that the surface of the tile is flat.In this traditional way,if the coating of cement mortar is not uniform,the ceramic tile is easy to be hollowing out and falling off.Due to the poor adhesion of ordinary cement mortar,large tiles or stones coated on the mortar layer must be mechanically fixed or reinforced,And there is silding resistance due to the ordinary cement mortar,so must be from the bottom of the paste ceramic tile,and between the tiles should use a locator to ensure stickup ceramic tile smooth vertical and horizontal,as well as the surface clean.Therefore,it can be seen that this method is time-consuming and inefficient, requiring a large amount of materials and high requirements of manual comstruction techniques.Due to the limitation of the properties of there materials,the construction quality is difficult to guarantee,and the quality problems such as the cavity and peeling of ceramic tiles are often present.


With the development of modern architecture techology,the use of traditional mortar has been limited.In most industrialized countries,the use of thin layer mortar has replaced the construction way of thick layer mortar.This kind of thin layer mortar is a mixture of cement,aggregate,polymer,special additives and filler.It is called “viscose mortar”.It is non-toxic and belongs to green products.By using cellulose ether and dispersible emulsion powder,the water retention,flexibility and bonding properties of mortar were greatly improved.In architecture,it only need to ceramic tile adhesive mortar mixed with waer evently,smear mortar paste using sawtooth trowel to large area in the substrate surface to form a unified adhesive mortar layer 3-4 mm thickness,and then a little bit the ceramic tile to the mortar layer.The tiles do not need to be fixed,and the tiles do not slide.In addition,you can paste from top to bottom.Neither ceramic tile nor substrate need to be soaked or pre-wet in advance,reduce the process and keep the building environment clean and tidy.Therefore,compared with thick layer mortar technology,thin layer mortar technology is more cost-effective and USES less materials,which has a wider range of applications,simpler,faster and safer.
