Waterproofing agent is a waterproof material commonly used in home decoration. As one of the new products, silicone waterproofing agent has quickly won people's recognition with its unique product features and advantages. So what is silicone water repellent?


At present, China is in the stage of large-scale construction. Concrete and reinforced concrete are the most important materials in construction. Concrete often affects the service life of buildings due to insufficient durability. A major factor affecting the durability of concrete is the intrusion of moisture. The intrusion of water is a necessary condition for concrete carbonization, sulfate corrosion, and corrosion of steel bars by chlorine salts. As a transport carrier, water is used to bring CO2, SO2, SO42+, Cl- dissolved in water into concrete, causing corrosion damage to concrete. At the same time, the intrusion of moisture causes the cements Ca(OH)2 and CSH-gel to dissolve, seriously affecting the durability of the concrete. Therefore, waterproofing the concrete to improve the impermeability of the concrete is an effective method for improving durability.


What is silicone waterproofing agent?
Silicone waterproofing agent is an ideal waterproofing agent. It not only has good water resistance, but also has good acid resistance, alkali resistance and high temperature resistance. It also has good antifouling properties and can prevent concrete soiling.


Silicone waterproofing agent is a new type of waterproof material that is non-polluting and non-irritating, and is widely used in the world's advanced countries. When the silicone water repellent is sprayed (or painted) on the surface of the building, it can form a colorless transparent, UV-resistant breathable film on the surface that is invisible to the naked eye. When the rain blows on it or encounters moist air, the water droplets It will naturally flow, and the moisture in the address will invade. At the same time, the dust on the surface of the building can be washed away, so as to protect the interior wall from moisture, mildew, clean the exterior wall and prevent weathering.

Silicone waterproofing agent waterproof life
Silicone water repellent is a new type of water-soluble waterproofing agent made by a variety of fatty acids and more than ten kinds of inorganic materials through high-temperature chemical reaction. The waterproof life is determined by the specific use.

Mechanism of action of silicone waterproofing agent
The silicone waterproofing agent is a water repellent waterproofing agent. When the silicone water repellent is on the surface of the silicon-based substrate, it penetrates into the interior of the substrate under the capillary action of the capillary. The silicone molecule dehydrates with the silanol group in the substrate to form an oriented silicone water film on the surface of the substrate and the surface of the capillary. The water-retaining film is a few nanometers thick and does not affect the appearance of the concrete. It prevents the capillary action of the substrate capillary against water, thereby preventing the intrusion of moisture. At the same time, the capillary is not blocked, so that the concrete maintains good air permeability.


Silicone waterproofing agent features
1. Excellent waterproof performance. Anti-seepage, leak-proof, waterproof, color retention, anti-pollution, anti-weathering, anti-salt and anti-weathering, anti-freeze and detachment of exterior walls, tiles and marble of buildings.


2, good ventilation. It does not block the pores and micropores on the surface of the building, and does not affect the emission of moisture inside and inside the wall. If the wall treated by it is put on a drowning coat, the wall is always dry.


3, strong durability, anti-pollution, anti-weathering and color retention, can penetrate into the wall a certain depth, so it is less affected by ultraviolet radiation and atmospheric aging.

Silicone waterproofing agent use method
1. Cleaning: Clean up the surface pollutants on the cement so that there are no floating soil, mortar and garbage.


2. Drying: Let the cement dry naturally.


3. Spraying: After the cement surface is dry, spray it evenly on the cement surface with a spray gun, brush and roller until the treated surface is completely saturated.


4. Drying: Allow the cement to dry naturally for 24 hours without contact with rainwater. After 24 hours, it can be installed and installed.


5, maintenance: no water, no pollution within 24 hours. Suitable for construction temperature 0~40oC


6. After painting, let the treated surface dry naturally, and then brush the surface a second time before the surface is dry. It can be applied by immersing, spraying or brushing with a rag, sponge, brush, roller and sprayer. After 5-10 minutes of application, wipe off the excess liquid with a soft cloth and keep it for at least 24 hours without water.


Silicone waterproofing agent is no better, these three shortcomings can not be avoided!
Many users have reported that the house has leaked after using silicone waterproofing agent, especially outside the outer wall. It is also a serious leak. Many people are wondering whether the waterproofing agent can really start. To the effect of waterproofing, if leakage still occurs after the waterproofing agent is applied, is it still necessary to apply the waterproofing agent?


It is true that the silicone waterproofing agent on the market is bound to have drawbacks, because the creation and development of any new type of thing is accompanied by many uncertainties. However, the phenomenon of water seepage and even repeated water seepage can only indicate that it is not The problem with silicone water repellents, but the products purchased are not true water repellents.

There are countless fake water-repellent agents on the market, most of which are even only poured out with tap water. The waterproof effect comes from the seller’s false-empty claims. These are destined to have waterproofing agents that use the effect of the effect, so that the reputation of silicone waterproofing agents has also changed. Not good, remind consumers to pay attention, when buying waterproofing agents, we must be cautious, as long as the requirements for waterproof, you must want to buy the most suitable.


Of course, the real silicone waterproofing agent is not all-around waterproof. He also has good waterproof performance only for the waterproofing of the outer wall. Even most people think that he is more of a material that is resistant to penetration. Instead of being truly waterproof, the M1500, for example, has more features to enhance the compactness of cement concrete.


Waterproofing agent can not form a dense impervious protective film, without any flexibility, and the density cannot be guaranteed. These three shortcomings make the waterproofing agent market more environmentally friendly, water resistant, weather resistant and more willing to choose silicone waterproofing. The agent can adapt to the deformation of the base layer and also improve the impermeability of the cement concrete food.
