The core function and working principle of wall curing agent

Wall curing agent, also known as "wall curing", is a water-based interface treatment material used to enhance the strength of the wall base, improve adhesion, and prevent dust and moisture. It is widely used in scenarios such as new house rough walls, old house renovations, and cement mortar sanding walls. It is a key primer process before the construction of putty, latex paint, and tile adhesive.

1、 Core functions and operating principles

Infiltration reinforcement: the curing agent penetrates into the wall base 3 – 5mm deep in the form of water-based lotion, reacts with free calcium ions in cement, forms a dense three-dimensional network structure, and significantly improves the surface hardness and compactness.

Dust and powder prevention: effectively seal the sand and loose cement particles, and prevent the problems of "powder falling" and "delamination" that may occur during subsequent putty application.

Enhance adhesion: A micro rough film layer is formed on the surface, which increases the bonding strength between materials such as putty, latex paint, and tile adhesive and the wall by more than 30%, significantly reducing the hollowing rate.

Auxiliary moisture prevention: It has certain water resistance performance and is suitable for pre-treatment of the base layer in damp areas such as kitchens and bathrooms, delaying water vapor erosion.

Applicable base: cement mortar wall, concrete wall, lightweight partition wall, gypsum board joint, exposed base after old wall removal.

Not applicable: Finished wall surfaces, wooden substrates, and metal surfaces that have been coated with latex paint.

2、 Mainstream types and product parameters

|Type | Representative Product | Solid Content | Penetration Depth | Drying Time | Environmental Protection Level | Applicable Scenarios|

|Water permeable type | Permanent G-6, Zhengxiang Z2 | ≥ 30% | 3-5mm | 4-8 hours | GB/T 23999 (formaldehyde free) | Sanding wall surface, newly built cement wall, industrial plant|

|Polymer lotion type | Nippon wall solid, Degao interface agent | 15 – 25% | 1 – 3mm | 2 – 6h | low VOC | civil residence, putty front primer|

|Epoxy modified type | Shandong Guanghan wall fixing | 20-30% | 2-4mm | 6-12 hours | Environmental certification | High humidity environment, heavy-duty wall|

Purchase suggestion:

For civil decoration, water-based lotion is preferred, with good environmental protection and convenient construction;

For severe sanding or industrial scenarios, choose high solid content permeable type (such as permanent G-6), which has a more durable curing effect;

Avoid using inferior products containing 801 glue and urea formaldehyde resin, as they can easily release formaldehyde.

3、 Construction technology and key points

Grassroots treatment:

Remove floating dust, oil stains, and loose particles, and repair cracks with putty;

The moisture content of the base layer should be ≤ 8%, and damp walls need to be dried or ventilated.

Mixing ratio and painting:

Generally, it is not diluted with water. Some products can be diluted with 0-10% water (according to the instructions);

Use a roller or brush to evenly apply 1-2 coats. After the first coat is dry (about 4-6 hours), apply the second coat;

The process of "making wool": Mix the wall and cement in a 1:1 ratio to form a paste, and use a spatula to scrape a thin layer to enhance the mechanical biting force. It is suitable for extremely loose base layers.

Environmental requirements:

Construction temperature ≥ 5 ℃, humidity ≤ 80%;

Good ventilation to avoid construction in confined spaces;

Do not touch or apply putty within 24 hours after painting.

Post construction effect: The wall appears uniformly milky white, with a slightly astringent texture, no stickiness, and no obvious odor.

Priority should be given to products labeled with "GB/T 23999", "formaldehyde free", and "solid content ≥ 30%";

Real time quotes can be obtained by searching for "Linyi Wall Fixing Manufacturer" on "Baidu AiGou", and some companies support free sample shipping.

5、 Common Misconceptions and Avoiding Pits Guide

Misconception 1: "If a new wall doesn't sand up, there's no need to fix it with a brush

Even without obvious sanding, there are still micro pores in the base layer. Brushing the wall can significantly improve the adhesion of putty and avoid later hollowing.

Misconception 2: "The thicker the wall, the better"

→ High consistency ≠ strong penetration. High quality wall reinforcement shall be lotion with good fluidity, which can naturally penetrate into the base course.

Misconception 3: "Wall fixing can replace putty"

The wall reinforcement is only used as a base coat and cannot be leveled or replaced by a putty layer. It must be scraped later.

Misconception 4: "Mixing other adhesives for use"

→ It is strictly prohibited to mix with 801 glue, white latex, and tile glue, as it will damage the chemical structure and cause bonding failure.
