How to Use Waterproof Breathable Membrane?

As a unique material, waterproof breathable membrane has dual functions: it can effectively prevent water penetration and allow water vapor to pass through to keep the internal environment dry and comfortable. In practical applications, its installation steps mainly include the following links:

1. Preliminary preparation

First, we need to conduct a comprehensive inspection and preparation of the installation foundation. If there are defects such as cracks and unevenness in the foundation, they need to be repaired in time. At the same time, remove dust, sand and other debris on the surface of the foundation to ensure that the foundation is dry and smooth, laying a good foundation for the laying of waterproof breathable membrane.

2. Substrate treatment

After completing the foundation preparation, the next step is to carry out substrate treatment. This step usually involves applying primer, which serves to enhance the adhesion between the foundation and the waterproof breathable membrane while reducing the chemical reaction between the two. After the primer is applied, wait for at least 24 hours to ensure that it is completely dry.

3. Laying of membrane

When the substrate is treated and dried, we can start laying the waterproof breathable membrane. During the laying process, it is necessary to ensure that the size of the membrane is consistent with the design plan to avoid unnecessary wrinkles or deformation. When laying, it should start from the bottom and gradually cover upwards to ensure the integrity of the membrane material. At the same time, special treatment is required at the joints of the membrane material to ensure the tightness and waterproofness of the joints.

4. Connection and sealing

After laying, the joints and peripheral seals need to be carefully treated. This usually includes heat fusion treatment of the joints to ensure the tightness and waterproofness of the joints. At the same time, the peripheral seals are reinforced to ensure that the waterproof breathable membrane is completely sealed with other parts of the object, thus forming a complete waterproof and breathable barrier.

Through the above steps, the waterproof breathable membrane can be successfully installed and function, providing long-lasting and effective waterproof and breathable protection for the object.
