Overview of Gypsum Waterproof Agent

The Gypsum waterproofing agent is a compound specifically designed to enhance the performance of waterproofing Gypsum-based products (such as gypsum board mortar containing gypsum and so on.). It is able to effectively stop moisture from entering and enhance the longevity and durability of gypsum products widely employed in the construction industry. Here is an in-depth review of gypsum’s waterproofing agents:

Definition: Gypsum repellents are a category of chemical compounds added to the gypsum substrates in order to increase their waterproofing properties, and to reduce the chance of water absorption and destruction to the structure.

Method of operation: By making a hydrophobic coating or closing the pores on the surface or inside the gypsum, it blocks water from leaking in; simultaneously, certain of the agents for waterproofing can enhance the microstructure of Gypsum, which increases its density and the strength.

Application of Gypsum Waterproof Agent

Gypsum board: used for indoor partition walls, ceilings and other parts to prevent mold and deformation in humid environments.

Gypsum mortar: applied to internal and external wall plastering to improve the waterproof performance of the wall and prolong its service life.

Repair materials: used to repair cracks and broken areas in old buildings to enhance overall waterproofing.

Decorative materials, such as gypsum lines, reliefs, etc., protect these fine components from moisture.

The Advantage of Gypsum Waterproof Agent

Enhance waterproofing performance: Significantly reduces water intrusion and keeps the plaster dry, avoiding moisture-induced expansion and contraction problems.
Extended service life: makes plaster more durable by increasing its stability and resistance to aging.
Improved construction quality: makes gypsum easier to work with and reduces the likelihood of rework.
Environmentally friendly: many modern waterproofing agents are formulated to be environmentally friendly and are not harmful to the environment or human health.

FAQs

Q1

How does gypsum waterproofing affect the hardening process of concrete?

Answer: 

Gypsum waterproofing agent reacts with calcium hydroxide in concrete to form hydrated calcium sulfoaluminate, which promotes the hardening process of concrete. At the same time, gypsum waterproofing agent can also inhibit the shrinkage of concrete and reduce the occurrence of cracks.

Q2

What effect does gypsum waterproofing agent have on the strength of concrete?

Answer: 

Appropriate amount of gypsum waterproofing agent can improve the strength of concrete. Because the gypsum waterproofing agent can fill the tiny gaps in the concrete and reduce internal defects, thereby improving the compactness and strength of the concrete.

Q3

How durable is plaster waterproofing?

Answer: 

The durability of gypsum waterproofing agent is related to many factors, such as the quality of concrete and environmental conditions. Generally speaking, high-quality plaster waterproofing agents can provide waterproof protection for a longer period of time and maintain good performance.

Q4

How to choose a suitable plaster waterproofing agent?

Choosing a suitable gypsum waterproofing agent needs to consider factors such as project requirements, concrete type, and environmental conditions. Gypsum waterproofing agents should be selected that have good compatibility with the concrete materials used, stable performance, and meet environmental protection requirements.

Q5

Are plaster waterproofing compounds compatible with other additives?

Answer: 

When choosing to use other additives, testing and verification should be conducted first to ensure compatibility and synergy between the gypsum waterproofing agent and other additives. Avoid performance degradation or material deterioration due to chemical reactions.

Q6

How to deal with the impact of gypsum waterproofing agent on the human body?

Answer: 

When using gypsum waterproofing agent, appropriate protective measures should be taken, such as wearing masks, gloves, etc. If it accidentally comes into contact with skin or eyes, rinse immediately with clean water and seek medical advice promptly. At the same time, long-term inhalation of dust or gas released by gypsum waterproofing agents should be avoided.
