On construction sites, there are two common base layers: brick walls and concrete walls. Bubbling typically occurs on concrete walls, primarily due to numerous through-pores present in the concrete surface. Therefore, to resolve bubbling when applying wall putty/gypsum, we must seal these through-pores. 1. Sealing Substrate Pores The most common method is applying a primer … Continue reading
The weather resistance of waterproof mortar The weather resistance of waterproof mortar is a critical performance indicator in practical applications. Enhancing this resistance helps the mortar withstand climate erosion, extend building service life, improve reliability and durability in complex environments, and reduce long-term maintenance costs. To improve the weather resistance of waterproof mortar, we offer … Continue reading
Dry-mix mortar is widely used in modern construction, from masonry and plastering to tile laying and self-leveling floors. However, in practical applications, dry-mix mortar often faces the following issues: Insufficient water retention → leading to premature moisture loss in the mortar and reduced bonding strength; Poor workability → Difficult to apply, requiring extra effort for … Continue reading
Waterproof mortar crack resistance While ensuring the density of waterproof mortar, its crack resistance cannot be ignored. This will ensure better and longer-lasting waterproofing, as cracks make it easier for water to seep through. How can this be improved? 1.Latex powder Add an appropriate amount of high-quality latex powder to improve the flexibility and deformation … Continue reading
In modern architectural coating systems, HPMC (hydroxypropyl methylcellulose) has become an indispensable key additive. Many people still view it solely as a “thickening agent,” but in reality, HPMC’s functions extend far beyond this. Thickening — The “Scaffolding” for Stabilizing Coating Systems HPMC’s most well-known function is thickening. By forming a network structure, it significantly enhances … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
