What Should Be Done When Using Cement Boards Outdoors

When using cement boards outdoors, a series of treatments are required to ensure their durability, aesthetics, and functionality. The following are the main handling measures:

1、 Waterproof treatment

Applying waterproof coating:

Waterproof coatings can effectively prevent water from seeping into the interior of cement boards, thereby protecting them from water erosion.

Before painting, the surface of the cement board should be cleaned thoroughly to ensure that there are no impurities such as dust and oil stains.

When applying, it should be evenly covered and the coating thickness should not be too thin. It is recommended to apply twice to achieve better waterproof effect.

Using waterproof adhesive:

Apply waterproof adhesive evenly on the surface of the cement board, allowing it to fully penetrate into the interior of the cement board, thereby enhancing its waterproof ability.

Setting up waterproof layer:

A waterproof layer can be installed on the surface of the cement board, such as using a waterproof film or adhesive to press it onto the surface of the cement board to achieve better waterproof effect.

2、 Sunscreen treatment

Adding sunscreen pigments: Sunscreen pigments can absorb ultraviolet rays and prevent the surface of cement boards from being damaged by ultraviolet rays. When choosing sunscreen pigments, the selection should be based on actual needs and color preferences, and consult professionals to obtain the correct addition method and proportion.

3、 Moisture-proof treatment

Applying moisture-proof agent:

There is a specialized cement board moisture-proof agent available on the market, which can be applied to the surface of the cement board. This moisture-proof agent has good moisture-proof and durability, and can effectively prevent moisture from entering the interior of the cement board.

When applying, attention should be paid to even application. It is recommended to apply twice to ensure moisture-proof effect.

Closed treatment:

Use sealing materials (such as plastic film, PVC flooring, etc.) to completely seal the cement board and avoid water infiltration. This method is relatively thorough, but requires high cost and technical level.

4、 Other handling measures

Control environmental humidity:

Install dehumidifiers or use air conditioning methods in the area where cement boards are installed to control the environmental humidity within an appropriate range (such as below 50%), in order to reduce the chance of cement boards getting damp.

Add drainage system:

When installing cement boards outdoors, it is important to ensure that the drainage system is unobstructed to reduce moisture issues caused by accumulated water. Drainage systems can be added on roofs or walls and regularly inspected and maintained to ensure their normal operation.

Regular inspection and maintenance:

Regularly inspect the condition of the cement board, and promptly address any issues such as damage, cracking, or water seepage. Regularly cleaning and maintaining the surface of cement boards, keeping them dry and clean, is also an important measure to extend their service life.

In summary, when using cement boards outdoors, waterproofing, sun protection, and moisture-proof measures need to be taken to ensure their long-term stable performance and service life. At the same time, it is also necessary to pay attention to measures such as controlling environmental humidity and increasing drainage systems to reduce the risk of dampness.
