Do you need 801 glue for bathroom and kitchen tiles?

First of all, 801 glue is mainly used to prepare paint putty or add to cement mortar or concrete to enhance the adhesive strength of cement mortar or concrete, and play a role in the bonding transition between the base layer and the coating. That is, it is to increase the strength of the wool or add it to the cement.

Now there is basically no need for 801 glue, which is prepared by polyvinyl alcohol and formaldehyde through polycondensation reaction in acidic medium and then amination. In particular, there is no standard on the market, the amount of formaldehyde contained in 801 glue is as long as 3-10 years, which not only makes people feel astringent, itchy nose, poor breathing, but also causes throat, nasal cavity, pneumonia, and even cancer. It is precisely because of the long-term harm of toxic 801 glue that the Ministry of Construction of the People's Republic of China clearly stipulated on July 4, 2001 that toxic glue should be eliminated in home decoration!

So what is it used for now?

Now concrete interface treatment agent, commonly known as wall solid, reinforcing agent interface agent, is used. Mainly by increasing the roughness of the surface of the base layer such as concrete and cement mortar or the strength of itself, the bond strength between the base and other products is significantly improved, and it is widely used in the surface treatment of various cement bases, which is more environmentally friendly.

Of course, you have to choose big brands, and some small brands are basically glue filling. So choose carefully when buying.

Without 801 glue, cement and sand ash are used.
