Base Treatment Agent

Base coating is the first coating in waterproofing projects. Its main function is to enhance the adhesion between waterproof coating and substrate and ensure the firmness of waterproof layer. Base coating is usually in liquid state and can be quickly cured after construction to form a strong bonding layer. During the construction process, base coating, as an important part of waterproof system, can not only improve the adhesion of waterproof coating, but also fill the tiny pores and cracks on the surface of substrate and reduce water penetration. Its properties include excellent adhesion, good permeability and air permeability. Base coating can penetrate into the pores of substrate, penetrate deeply and firmly adhere to substrate, and provide strong support for subsequent waterproof coating. At the same time, base coating has good flexibility and crack resistance, can adapt to the slight changes of substrate, and avoid cracking of waterproof layer due to temperature change or external force. The construction of base coating is simple and fast, and the subsequent process can usually be carried out in a short time after the construction is completed, which saves the construction period. It has a wide range of uses and is suitable for waterproof treatment of various building structures, especially when the substrate is uneven or cracked, it can effectively improve the waterproof effect.

Advantages

Enhance adhesion: The base coating can enhance the bonding force between the waterproof coating and the base layer, ensure that the waterproof layer is firmly bonded to the substrate, prevent the coating from falling off or bubbling, and extend the service life of the waterproof system.

Fill the cracks and pores of the base layer: The base coating can penetrate and fill the tiny cracks, pores and uneven parts on the surface of the base layer, provide a uniform coating foundation, effectively prevent moisture from penetrating into the base layer, and improve the waterproof effect.

Improve waterproof performance: As the first line of defense of the waterproof system, the base coating can provide a better foundation for the subsequent waterproof layer, making the entire waterproof system more complete and durable, and preventing moisture leakage.

Good flexibility and crack resistance: The base coating has good flexibility and crack resistance, can adapt to the slight deformation or temperature difference of the base layer, prevent the waterproof layer from cracking due to changes in the base layer, and ensure the waterproof effect.

Easy construction: The base coating is easy to construct, usually by brushing, rolling, etc., which is easy to operate and can be completed quickly, saving construction time.

Fast drying speed: The base coating dries quickly after construction, and usually solidifies in a short time, providing a quick progress for the subsequent waterproof layer construction.

Wide applicability: The base coating is suitable for a variety of different

Improve durability: The base coating can effectively improve the entire type of base, such as concrete, masonry, metal, wood, etc., and can be widely used in waterproofing projects in building roofs, basements, kitchens, bridges and other parts.

The durability of the waterproof system reduces the risk of leakage caused by base problems and ensures that the waterproof layer can play a long-term and stable role.

Cost savings: By using the base coating, the difficulty of subsequent waterproof layer construction can be reduced, and poor waterproofing effects caused by base defects can be avoided, thereby reducing the cost of repairs and rework.

Work Suggestions

For cracks, holes or uneven parts in the base layer, cement mortar, repair glue and other materials should be used to fill and repair them first to ensure that the base layer surface is flat and solid.

The base layer should be dry, and the moisture content of substrates such as cement and concrete should be controlled below 8%. Overly wet base layers will affect the adhesion and curing effect of the coating. Before construction, the base layer should be completely dry.

Single-component coating: Use directly from the barrel. Stir thoroughly before construction to ensure uniform coating.

Two-component coating: Mix components A and B according to the proportion required by the manufacturer, stir evenly to ensure that there are no bubbles. The stirring time is usually 3-5 minutes. After stirring, it should be used within the specified time.

Brushing: Use a brush or paint brush to evenly apply the coating on the surface of the base layer, which is suitable for construction of small areas and complex parts.

Rolling: Use a roller to evenly roll the coating on the base layer, which is suitable for large-area construction and convenient operation.

Spraying: Use spraying equipment to spray the coating, which is suitable for large areas and construction environments that require higher efficiency.

The thickness of each coat of paint should be kept between 0.5-1.0mm to avoid excessive coating that causes sagging or incomplete curing.

The paint should be fully stirred before use to ensure that there is no sediment inside the paint, especially for two-component paint. Uneven stirring will affect the quality of the coating.

Avoid too thick a coat at a time when brushing. Too thick a coat will cause the paint to sag or incomplete curing, affecting the waterproof effect and adhesion of the coating.

Transportation And Storage

The base coating is usually packaged in barrels or barrel boxes. The packaging should be well sealed to ensure that it is not damp or leaking. Avoid violent collisions during transportation to prevent packaging damage. The basic information and precautions for use of the waterproof coating should be clearly marked on the packaging.

When transporting the base coating, avoid exposure to extreme weather conditions, such as high temperature, severe cold, rain and snow. Especially in hot seasons, avoid direct sunlight to prevent the paint from curing prematurely during transportation.

Base coatings such as polyurethane are sensitive to temperature and should be kept at a moderate temperature during transportation. It is usually recommended that the transportation temperature be between 5℃-35℃ to avoid freezing of the coating due to low temperature or premature curing of the coating due to high temperature.
