Bubbling after wall putty application is a common problem. It can be effectively solved by identifying the cause and taking targeted measures. The following are specific solutions: 1. First, identify the cause of the bubbling • Improper base treatment: oil stains and dust on the wall have not been cleaned, or the base is damp.. read more →

First, the reasons for putty blistering 1. Uneven mixing. 2. Putty with too much water, mix too wet. 3. The moisture content of the base is too high, while the density is too large or too small. Due to containing abundant voids. Putty with high water content, and thus impermeable, easy to make the construction.. read more →

Crack-resistant mortar Crack-resistant mortar is a mortar made from a crack-resistant agent made from polymer emulsion and additives, cement, and sand mixed with water in a certain ratio to meet certain deformation requirements and prevent cracking. Features The mortar waterproof layer is corrosion-resistant and alkali-resistant, which can prevent surface damage caused by weather conditions. The.. read more →

1. Do you understand the importance of the “open window period” in construction? In floor construction, the “open time” of self-leveling mortar is one of the key indicators determining the overall construction quality. The open time refers to the time window during which the material maintains good construction fluidity after mixing. If the open time.. read more →

Density of waterproof mortar To make a good waterproof mortar, it is not only necessary to improve its water repellency but also to enhance its water pressure resistance, which often depends on the density of the mortar. What methods can be used to improve the density of waterproof mortar? Optimal aggregate mix Use aggregates of.. read more →

Because polyvinyl alcohol has higher bonding strength than latex powder, it can be used to replace part of the latex powder in crack-resistant mortar within the scope of cost control. However, polyvinyl alcohol cannot be used entirely because latex powder has the following characteristics that polyvinyl alcohol cannot compensate for. Flexibility and crack resistance Since.. read more →

In construction, plaster materials are widely used in plastering, wall leveling, and decorative coatings due to their environmental friendliness and light weight. However, one of the most common and headache-inducing problems at construction sites is hollow drums, delamination, and flaking. The underlying cause is often insufficient plaster adhesion and poor water retention. So, how can.. read more →

Water-Reducing Agent Polycarboxylic acid-based water-reducing agents have developed and been applied rapidly. They are widely used in major and key engineering projects such as water conservancy, hydropower, water engineering, marine engineering, and bridge construction. Mechanism of Polycarboxylic Acid Water-Reducing Agent When cement is mixed with water, due to the intermolecular forces between cement particles, the.. read more →

Polycarboxylic acid water reducing agent is a commonly used concrete additive, which can effectively reduce the amount of cement in concrete, improve the fluidity of concrete and reduce the shrinkage of concrete. However, the use of polycarboxylic acid water reducing agent also needs to pay attention to some problems. The following is a detailed introduction.. read more →

Differences Between Dry-Mix Mortar and Traditional Mortar One of the significant differences between dry-mix mortar and traditional mortar lies in the use of small amounts of chemical additives for modification. If a single additive is added to dry-mix mortar, this is referred to as primary modification; if two or more additives are added, it is.. read more →
