Dry mix mortar cracking problem 1. What is plastic cracking of dry-mixed mortar? Plastic cracking refers to the cracking of the mortar before or during the hardening process. It generally occurs in the early stages of mortar hardening, and plastic cracking cracks are generally thicker and shorter in length. Reason analysis: Shortly after plastering, the

Reasons for applying interface agent in self-leveling construction

By |2024-05-27T06:35:57+00:00May 27th, 2024|Industry knowledge|

In gypsum-based self-leveling construction, the main reasons for applying interface agent are as follows: 1. Sealing the base layer: The main function of the interface agent is to seal the base layer. Prevent the base layer from absorbing water, causing self-leveling to lose water too quickly and cause cracks. 2. Enhance bonding strength: The interface
