Application of redispersible polymer powder in putty

In the external insulation system for exterior walls, the application of the putty layer must follow the "flexible transition" principle: the flexibility (deformation resistance) of the putty layer must be higher than that of the underlying plaster mortar base, while being lower than that of the decorative coating layer on its surface. This ensures that each layer of material can gradually release and absorb stress, preventing cracking due to incoordination of deformations. Therefore, putty used in insulation systems often requires the addition of a sufficient amount of redispersible polymer powder to ensure adequate flexibility.

The important role of redispersible emulsion powder in self-leveling

By incorporating 2% to 3% of redispersible emulsion powder, the wear resistance of self-leveling mortar can be significantly improved. The redispersible polymer powder disperses and forms a film within the mortar paste, filling the pores of the paste and interlocking with the hydration products of cement to form a three-dimensional network structure, thereby making the mortar structure denser.

Three major impacts of redispersible polymer powder on tile adhesive

In the production of tile adhesive, redispersible polymer powder (RDP) plays a crucial role. It does not only significantly enhances the performance of tile adhesive but also effectively addresses common issues during construction, such as tile detachment, hollowing, and cracking.

The Characteristics of Insulating Mortar

The insulating system made from inorganic materials is composed entirely of pure inorganic substances. It is resistant to acids and bases, corrosion, does not crack or peel, and has high stability, eliminating aging issues, thus lasting as long as the building walls.

Waterproof mortar in dry mixed mortar

Waterproof mortar refers to a rigid waterproof material that achieves waterproofing and impermeability by improving the compactness and crack resistance of mortar. Mainly used for waterproofing projects that will not cause harmful cracks due to structural settlement, temperature, humidity changes, and vibration. There are three types of waterproof mortar used as waterproof layers in waterproofing projects: (1) rigid multi-layer plastering cement mortar; (2) Waterproof mortar mixed with waterproofing agent; (3) Polymer cement waterproof mortar:

What properties of mortar can be improved by redispersible polymer powder (RDP)?

RDP redistributes in water and, after curing, forms a continuous polymer network/film inside the mortar pores and around cement hydration products. This strengthens bonding between particles, improves flexibility, and blocks part of the pore channels—so the hardened mortar becomes stronger in adhesion, more flexible, and more durable.

Let’s get to know basecoat (render) mortar

Basecoat mortar is made by mechanically mixing cement, quartz sand, a polymer binder (redispersible polymer powder, RDP), and various additives. It is mainly used as the crack-resistant protective layer on the outside of the insulation layer in an EPS thin-coat external insulation system (ETICS/EIFS), so it is also called polymer-modified crack-resistant basecoat mortar. It is applied on different types of insulated wall surfaces to form an excellent crack-resistant and water-resistant coating layer. This helps protect the overall performance of the insulation base layer, improves adhesion/compatibility at the interface of the insulation surface, and provides an excellent substrate for the installation of subsequent finishing materials. Basecoat mortar is required to have good workability to make application easier. It also needs high bond strength so that the mortar layer bonds firmly to the substrate, ensuring long-term resistance to cracking and preventing hollowing/debonding and detachment. In addition, when used in humid environments or areas subject to external impact, it should have good water
