What is the function of wall curing agent

Wall curing agent (commonly known as "wall curing") is a water-based polymer interface material used for pre-treatment of the base layer before decoration. Its core function is to comprehensively improve the stability of the wall base layer and the adhesion of subsequent construction materials through physical penetration and chemical bonding. The following is a systematic analysis of its functions:

Core mechanism of action

Penetrating and solidifying loose base layer

Wall fixing can penetrate into the wall by 2-5mm and react with free calcium ions, calcium carbonate and other components in cement mortar to form a mesh like crystalline structure, effectively locking loose sand particles and floating ash into a whole and solving the problems of sanding and powder falling on the walls of rough and old houses. If no more dust falls off when touched by hand, it is the completion of curing.

Enhance bonding strength

Applying putty, latex paint, wallpaper, or tile adhesive before construction can increase the bonding strength between the base and surface layers by more than 30%, significantly reducing the risk of hollowing, cracking, and peeling. Its function is similar to "double-sided tape", but it acts on the microstructure level rather than surface adhesion.

Sealed capillary pores, dustproof and moisture-proof

After drying, a dense transparent film is formed to block the infiltration of water vapor and dust overflow inside the wall, providing a clean and stable base for subsequent construction. However, it should be noted that wall reinforcement cannot replace waterproof layers, and special waterproof coatings are still required for wet areas such as bathrooms and kitchens.

Applicable scenarios

|Scenario type | Recommended use | Reason explanation|

|New house rough wall| Highly recommended | Cement plaster layer generally has insufficient strength and sanding problems, and wall fixing is a necessary pre-treatment|

|Renovation of old houses| After removing the old coating, the base layer is exposed and the strength is severely reduced, requiring re curing|

|Lightweight partition wall (gypsum board)| Recommendation | Prevent putty from drying, cracking, and falling off due to the substrate absorbing water too quickly|

|Smooth concrete wall| Recommendation | Increase surface roughness to enhance bonding and anchoring strength|

|The wall has become damp/moldy again|  Prohibited use | Wall fixing cannot solve structural water seepage, but may instead seal off moisture and cause coating peeling|

|As a waterproof layer|  Absolutely prohibited | can only seal micropores, cannot withstand water pressure, strictly prohibited for use in kitchen, bathroom, basement waterproofing|

Key differences from similar products

|Comparison item | Wall curing agent (wall curing) | Interface agent | Primer|

|Main functions | Penetrating curing, enhancing base strength | Increasing surface roughness, roughening bonding | Sealing and alkali resistance, isolating putty layer|

|Construction stage | Before putty construction (bottom layer) | Before putty construction (smooth surface) | After putty polishing, before latex paint|

|Color characteristics | yellow lotion, easy to identify missing coating | white or milky white, transparent after drying | white or colored, strong coverage|

|Typical application scenarios | Sanding cement wall, old building base | Smooth concrete, before tiling | Putty layer anti alkali, color matching|

|Is it replaceable | non replaceable | non replaceable | non replaceable|

Note: Wall curing is a type of "interface agent", but in the market, "wall curing" specifically refers to yellow products with penetration curing as the main function, while "interface agent" refers to all base treatment agents. There is a significant difference in functional emphasis between the two.

Key points of construction

Grassroots treatment: Remove floating dust and oil stains to ensure that there is no loose material on the surface.

Dilution ratio: Generally diluted with 1:0-10% water, depending on the product instructions; The "wool making" process does not add water and is mixed with cement to form a paste like consistency.

Construction method: Use a roller or brush to evenly apply 1-2 coats, ensuring no omissions.

Drying time: Dry at room temperature for 2-4 hours before proceeding to the next process.

Environmental requirements: Construction temperature ≥ 5 ° C, avoid working in rainy or high humidity environments.

Industry Trends and Environmental Tips

The current mainstream products are water-based and environmentally friendly, in compliance with the GB 18582-2020 "Limit of Harmful Substances in Interior Decoration Materials and Interior Wall Coatings" standard.

There are some unscrupulous merchants in the market who use construction glue (such as 107 glue) to impersonate wall fixing. Such products have excessive VOC, are prone to aging and cracking, and the wall surface is prone to yellowing and peeling after construction. It is necessary to choose legitimate brands (such as Nippon Paint, Jibaishi, etc.) and check the testing report.
