What is the material of the interface agent in the plastering project?

In plastering projects, the interface agent is used to treat the surface of the object. The treatment may be physical adsorption or coating, and is often a physical and chemical effect. The purpose is to improve or completely change the physical and technical properties and surface chemical properties of the material surface. Products that aim to change the physical and chemical properties of the interface of an object can also be called interface modifiers. Treating the surface of an object to improve the surface properties of the material is called surface treatment. Interface agents are used in different fields, and the process methods and purposes of surface treatment are different. The common interface agent treatment and modification of the interface of an object can be divided into four process types: wetting and impregnation, coating treatment, coupling agent treatment and surface modification.

Do I need to apply interface agent before puttingty on the wall?

1. Apply interface agent before puttying the wall.

2. Because there is a lot of dust on the wall, if you don’t apply the interface agent, it will affect some of the later processes. After applying the interface agent, different materials can be well integrated and used together.

3. After the putty is scraped, if you want to paste wallpaper or make diatom mud, you must also apply a layer of base film. If you directly spray latex paint, then you do not need to apply a base film.

When applying the interface agent to the wall, you can choose to use a roller or a machine.

The role of wall interface agent

The role of the wall interface agent is to play a connecting role, consolidate the base and allow other substances to cover it. If there is some powder on the interface to be processed, it can be used as a bottom sealer. The interface agent has excellent permeability and can fully infiltrate the surface of the material of the wall base, make the base more dense through gluing, and improve the adhesion of the interface. Improve the bonding strength between mortar or putty and the wall surface to prevent hollowing. It is suitable for brick-concrete wall plastering and compacting the base before scraping putty. The interface agent can improve the adhesion of the smooth base and is also suitable for the bonding of wall cloth and wallpaper. Due to the convenient coating, thin film, and appropriate initial viscosity, it is particularly suitable for the bonding of wall cloth and wallpaper, and is not easy to produce dead folds and bulges. It can also be used for base surface hair creation. Before scraping putty, it is generally applied on the cement sand leveling layer of the plastering layer. The main function is to strengthen the bonding between the two layers of materials, so that the putty can be better bonded to the wall surface, and reduce the probability of quality problems such as hollowing and delamination.
