Who said what are the characteristics of reactive waterproofing coatings?

Features and advantages: Strong adhesion to the substrate - the active ingredients in the slurry can penetrate into the pores, microcracks and chemical reactions in the substrate to form crystals that block the passage of water, and integrate with the substrate to play a waterproof role. And the wet area can be constructed, the waterproof layer can be directly paved with tiles and painted, and the waterproof layer has high wear resistance.

Resistant to high hydrostatic pressure—As the crystals penetrate deep into the pores of the substrate, they remain robust and waterproof under high hydrostatic pressures. It has the waterproof effect of negative water surface - the crystalline formed by the product forms an integral part with the substrate, which can block the passage of water in all directions, so it has obvious waterproof effect on both the frontal and negative water surface. Reactive types are divided into two types: two-component and one-component.

The two-component component is composed of a powder part and a liquid part in a certain proportion. The powder is composed of high-quality cement fine sand and a unique active substance, while the liquid is composed of high-tech polymers and additives. The two sets of materials are mixed and painted on the cement base surface to achieve a waterproof effect.

The one-component waterproofing material is composed of high-quality cement fine sand and unique active substances, while the liquid additives are made of high-tech polymers and additives. Driven by the action of water, the active substance penetrates into the capillary pores of the substrate, and a chemical reaction occurs to form branch-like crystals, which inhibits the passage of water from all directions. Strong adhesion to the substrate - the active ingredients in the slurry can penetrate into the capillary pores, micro-cracks and produce chemical reactions in the substrate to form crystals that block the passage of water, and integrate with the substrate to play a waterproof role.

And the wet area can be constructed, the waterproof layer can be directly paved with tiles and painted, and the waterproof layer has high wear resistance. Resistant to high hydrostatic pressure—As the crystals penetrate deep into the pores of the substrate, they remain robust and waterproof under high hydrostatic pressures. It has the waterproof effect of negative water surface - the crystalline formed by the product forms an integral part with the substrate, which can block the passage of water in all directions, so it has obvious waterproof effect on both the frontal and negative water surface.

At present, there are four types of waterproof coatings for indoor use on the market according to their properties: flexible mortar, rigid mortar, one-component polyurethane and acrylate, which have different properties and have their own advantages and disadvantages.

Flexible mortar: The ratio of emulsion to mortar is 5:4, which is elastic, and will not affect the waterproof effect even if the base layer is deformed and cracked.

It is mostly used on the front surface of the wall and the ground, and can not be used on the back water surface such as the top surface. There is also a type of silicone waterproof coating in the flexible mortar, which belongs to the high-grade flexible mortar, with good elastic tension and flexibility, but it is more expensive and very rare in the market.

Hard mortar, also known as rigid mortar: the ratio of emulsion to mortar is 1:4, and there is no need to treat the coating after brushing, and it can be directly tiled, which is more convenient.

After curing, it forms a cement hard block, which will not bubble and seep water, and its biggest advantage is that the waterproof effect of the back surface is very good. The disadvantage of this coating is that this kind of mortar has a high hardness and is easy to crack with the deformation and cracking of the base layer, so it is generally used for waterproofing the back surface.

One-component polyurethane: both indoor and outdoor, the coating is very thick, about 3 mm, and the elastic tension is more than 300%, the cracking of any substrate will not make it crack, and the waterproof effect is the best. Although the safety performance is controlled within the environmental protection requirements, the smell of this waterproof coating is larger, which is difficult for ordinary people to accept, and the environmental performance of very few brands is not up to standard.

Polyurethane is gelatinous and very thick, and it requires the use of a scraper, which is laborious and complicated. After brushing the paint, it is necessary to carry out surface treatment (brushing or sanding) to increase friction and make it easy to tile.

Flexible—can cover cracks as thin as a hair and can withstand slight vibrations. Concrete remains breathable – crystals formed within the concrete capillary will still have pores equivalent to fine ones, through which water cannot pass through, while air and water vapor can still pass through. Non-toxic and harmless—can be used directly in drinking and fish ponds.

Two-component coatings are generally divided into two types: flexible and general-purpose! According to the main components of film-forming substances According to the main components of coatings, they can be divided into the following four categories: synthetic resins, rubber, and rubber asphalt.

Waterproof coatings can be divided into five categories: asphalt, polymer modified asphalt (also known as rubber asphalt), synthetic polymer (which can be further divided into synthetic resin, synthetic rubber), inorganic and polymer cement. According to its state and form, it can be roughly divided into three categories: solvent-based, reactive, and emulsion-based.

Summary. Reactive waterproofing coating is a coating material that can chemically react with the substrate to form a waterproofing layer. According to different chemical compositions and application scenarios, reactive waterproofing coatings can be divided into the following types:

1.Cement-based reactive waterproof coating: mainly composed of cement, polymer, etc., which reacts with free calcium ions in the cement substrate to form hydration products, and then fills the micropores of the substrate to improve the waterproof effect.

2.Polyurethane reactive waterproof coating: mainly composed of polyurethane resin, curing agent, etc., the two components are mixed and reacted during construction to form an elastic polymer film, which has good weather resistance and chemical resistance.

3.Acrylic reactive waterproof coating: mainly composed of acrylic resin, cross-linking agent, etc., the resin and cross-linking agent cross-link reaction during construction to form a continuous and dense waterproof layer, with good durability and temperature resistance.

4.Polyurea reactive waterproof coating: mainly composed of polyurea resin, amino curing agent, etc., after the coating is constructed, the resin reacts with the curing agent to form an elastomer to form a continuous and uniform waterproof film, which has good freeze-thaw resistance.

These reactive waterproofing coatings all have good waterproofing results and are suitable for different substrates and use cases. When selecting and using, it is necessary to make a reasonable choice according to the specific needs and circumstances, and follow the instructions of the paint manufacturer for construction.

You can refer to the red apple paint js composite waterproof coating.

General-purpose waterproof coating, also known as JS waterproof coating. It is a two-component waterproof material composed of acrylic emulsion and additives and a powder composed of cement, sand and mineral powder in a specific proportion. After the two materials are mixed, a chemical reaction occurs, which not only forms a surface coating for waterproofing, but also penetrates into the base material to form a crystal to block the passage of water, so as to achieve a double anti-hidden water effect.

Rigid waterproof material, outstanding bonding performance, mainly used for waterproof and moisture-proof treatment of toilets, kitchens and bathrooms. Compared with other solvent-based waterproof coatings and waterproofing membranes, the biggest feature of Wanshibo waterproofing material is environmental protection and safety.

Under the action of external force, it does not peel off or delaminates, and can form a stable waterproof whole.

Solids refers to the proportion of solids contained in a waterproofing coating. Since the solid components in the paint form a coating film after brushing, the solid content is closely related to the thickness of the film and the quality of the coating film. Heat resistance refers to the fact that the waterproof film after the waterproof coating is formed does not soften and deform at high temperatures.

Non-flowing performance, i.e., high temperature resistance. Flexible Hu Pei refers to the ability of the film layer after the formation of waterproof coatings to maintain flexibility at low temperatures. It reflects the application and use performance of waterproof coatings at low temperatures.

Impermeability refers to the performance of waterproof coating without leakage at a certain water pressure (hydrostatic pressure or dynamic water pressure) and within a certain period of time. It is the main quality index of waterproof coatings to meet the requirements of waterproof function. The ability of the extended waterproof coating film to adapt to the deformation of the base layer.

After the waterproof coating is formed, it must have a certain extensibility to adapt to the deformation of the base layer caused by temperature difference, dry and wet and other factors, and ensure the waterproof effect.

If the base layer is treated before painting. The brushing of waterproof paint has a lot to do with the condition of the ground base, the more uneven the base, the more paint is used. Therefore, before applying waterproof coatings, it is best to treat the base layer simply and try to smooth the base layer as much as possible.

Secondly, the ground should be guaranteed to be dust-free, soil-free, oil-free, and the cloth can be carefully mopped to remove all the dust, otherwise it will cause cracking and peeling of the waterproof coating, affecting the waterproof effect. The purchase of products should focus on the nature, the names of waterproof coatings on the market are varied, such as; Slurry; Mortar; Some people say that the type is more suitable for indoors, but according to relevant professionals, the most important thing is to look at the nature of the waterproof coating, which is generally marked as is; General Purpose; or flexible; , and then look at the ratio of mortar to emulsion, such as 12kg+8There are also product labels; Kitchen and bathroom talk about only use; In fact, this is just a gimmick, and the general indoor waterproof coating can be used in the kitchen and bathroom.
