Acrylic resin waterproof coating

The ingredient is acrylic resin, an environmentally friendly, safe and non-toxic water-based waterproof coating. It is easy to operate and suitable for DIY application. It is the most common type of waterproof paint.

Elastic cement

(Bulletproof mud)

• Elastic cement (abbreviated as elastic cement) is a common building waterproof material, which is a mixture of water-based resin (such as acrylic resin EAV) and hydraulic powder (cement sand, etc.). Compared with ordinary cement, elastic mud has higher elasticity and better waterproof performance, but compared with pure resin materials, the waterproof effect is still slightly inferior.

• Since elastic mud is a mixture of resin and cement sand, if the coating is too thick, it will not be easy to dry. Therefore, during construction, multiple thin coats must be applied, and each layer must be completely dry before the next layer can be applied to eventually form a complete waterproof membrane. Generally speaking, at least two layers of elastic mud are required to ensure good waterproofing effect.

• Depending on the resin composition, elastic cement can be further divided into acrylic elastic cement and EVA elastic cement. The main difference between the two is the hardness. However, no matter which type it is, the construction method and basic properties are the same, making it a functional material widely used in building waterproofing projects.

Vinyl 

(Emulsified asphalt)

• The main components of emulsified asphalt are asphalt and emulsifier. If polymer resin is added, it is called rubberized asphalt. If water-based PU and acrylic acid are added, it is called water-based PU black glue. Emulsified asphalt is a more traditional waterproof material and is suitable for waterproofing projects in various areas. However, the adhesion between emulsified asphalt and exterior wall finishes (tiles) is poor and it is not suitable for exterior wall waterproofing projects.

• But now there are many polymer resins, rubber, asphalt elastic aggregate copolymer modified, more as a waterproof local reinforcement use

• Black glue is a black waterproof material that only needs to be applied to the waterproof part by brushing, and then it will form a waterproof layer after it dries and hardens naturally. This type of material is generally suitable for local repair projects, but if it is to be used for comprehensive waterproofing, reinforcing fibers must be added.

PU waterproof coating

• PU waterproof coating is made of a polymer material called polyurethane. Its properties are between rubber and plastic, similar to resin, and it has excellent elasticity and waterproof properties.

• Since PU waterproof coatings have high requirements for the construction surface, if the ground or wall is uneven, or there is residual moisture, the waterproof layer will not be able to adhere tightly, which may cause cracking problems in the future. Therefore, during construction, it is necessary to ensure that the surface is dry and flat to enhance the waterproofing effect and durability.

• The method of applying PU waterproof coating is similar to elastic cement. The next layer can only be applied after the previous layer is completely dry. In addition, if there is still moisture remaining on the ground, it is not suitable for coating, otherwise it may affect the integrity of the coating and cause surface defects.

• Due to its excellent wear resistance, PU waterproof coatings are widely used in places that require high durability, such as underground parking floors, laboratory floors, and clean room floors. However, if you need to lay tiles or PC materials on the PU waterproof layer, it may affect the adhesion and damage the waterproof layer. In addition, if the waterproof layer fails, it must be completely scraped off and reapplied, which will greatly increase the maintenance cost. Therefore, special consideration must be given to environmental requirements during application.

Permeable crystalline waterproof coating

• Permeable crystallization is a waterproofing technology that penetrates into the concrete through the material, forming crystals in the pores, effectively blocking the moisture channels. This technology is particularly suitable for local or small-scale water leakage problems. It can quickly block water seepage and provide immediate and long-lasting waterproofing effect.

• This material has excellent permeability and can penetrate deep into the concrete structure. Even without destroying the original structure, it can still perform a good waterproof function. It is particularly suitable for use in high water pressure environments or building surfaces that are prone to water seepage. In addition, it is suitable for substrates of various shapes, has flexible construction, and can effectively improve the overall waterproof ability of concrete.

Transparent waterproof glue

• Waterproof glue is a waterproof coating whose main component is acrylic emulsifier. It has high transparency and will not affect the color and appearance of the original material. Therefore, it is particularly suitable for waterproofing projects that need to maintain their original appearance. Due to its simple construction, it is suitable for DIY and can be applied to all kinds of walls and floors such as tiles, cement, and washed gravel.

• Many people choose to buy waterproof glue by themselves as the most convenient waterproof coating. However, the coating of waterproof glue is relatively thin, and the waterproof effect is relatively short-lived. If it is in a waterlogged environment for a long time, the effect will decline rapidly. Therefore, it is not suitable for areas prone to water accumulation, and in outdoor environments, the waterproof glue is easily deteriorated due to weather conditions, reducing its waterproof performance.
