What materials do plastering walls need besides cement?
When cement is used to paint the mud wall, nano-silicon waterproof glue can also be used to paint the surface for waterproof construction.
Nano-silicon refers to crystalline silicon particles with a diameter less than 5 nanometers (654.38+0 billion (654.38+0 grams) one meter). Nano-silicon powder has the characteristics of high purity, small particle size and uniform distribution. Large specific surface area, high surface activity and low bulk density. The product is non-toxic, tasteless and has good activity. Nano-silica white emulsion, non-toxic, non-irritating, non-flammable, PH 12, density 1. 15 ~ 1.2. It has excellent waterproof and seepage-proof effect when used on the base surfaces of brick, cement, gypsum, lime, paint, asbestos, perlite and insulation board. It has the functions of preventing buildings from weathering and frost cracking, cleaning external walls, preventing pollution, mildew and moss; Reliable quality, good durability, acid and alkali resistance, good weather resistance, no corrosion to steel bars, safe use and convenient construction. Mortar impermeability ≥S 14, concrete impermeability ≥S 18. Technical performance conforms to JC 474- 1999 [Waterproofing agent for mortar and concrete] and JC/T902-2002.

In JS coating, both polymer and cement have gelling effect.
Polymer: refers to those compounds with relative molecular weight greater than10,000, which are mainly composed of many atoms or groups of atoms through covalent bonds.
Hundreds of atoms are covalently bonded to each other to form compounds with particularly large relative molecular weight and repeated structural units. Cement: Cement can be divided into (1) ordinary cement according to its use and performance;
Cement commonly used in general civil engineering. General purpose cement mainly refers to six kinds of cement specified in GB 175—2007, namely portland cement, ordinary portland cement, slag portland cement, pozzolanic portland cement, fly ash portland cement and composite portland cement. (2) Special cement: special purpose cement. For example: G-class oil well cement and road portland cement. (3) Characteristic cement: cement with outstanding performance. Such as: quick-hardening portland cement, low-heat slag portland cement, expanded sulphoaluminate cement, phosphoaluminate cement and phosphate cement.
