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 […]
The weather resistance of waterproof mortar The weather resistance of waterproof mortar is a critical performance indicator in practical applications. If it can withstand climatic erosion, extend the service life of buildings, enhance reliability and overall durability in complex environments, and reduce long-term maintenance costs, it is of great importance. How can the weather resistance […]
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 […]
Shanghai, August 2025 — Vitchem, a global leader in concrete additive solutions, will showcase its high-performance concrete additive series at the 2025 World of Concrete Asia (WORLD OF CONCRETE ASIA).The exhibition will take place from August 13 to 15, 2025, at the Shanghai New International Expo Centre (SHANGHAI NEW INTERNATIONAL EXPO CENTRE). Vitchem cordially invites […]
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 […]
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 […]
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 […]
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 […]
DÜSSELDORF, GERMANY – June 28, 2025 – VITCHEM, a global provider of dry-mix mortar additives, concrete admixtures, and cellulose ethers, was represented at the EUROPEAN MORTAR SUMMIT 2025 by Amina from its German headquarters. The summit took place from 26–27 June 2025 at the Courtyard by Marriott Düsseldorf Seestern, gathering key stakeholders across the construction […]
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 […]
