The open air balcony is made of membrane, and there is a water leak, what waterproof material is use

The balcony area is small, and it is generally better to use waterproof coatings, such as polyurethane and JS waterproof coatings. Because when burning the coil, the area is small, and the edges and corners are difficult to burn in place. In the event of a water leak, it is best to brush it with JS white paint, the corners of the edges.

If the membrane has been channeled water, basically this layer of membrane has no waterproofness, and the membrane is suitable for outdoor large-scale engineering construction, for home decoration it is recommended to use waterproof coatings and other environmentally friendly, convenient construction waterproof materials.

The waterproofing of the open balcony requires a combination of rigidity and flex construction

1.The first layer is made of flexible waterproofing, such as K11 waterproof slurry flexible type.

2.The second time do mortar waterproofing (mortar waterproofing agent) as a protective layer.

Open balcony waterproofing can not use a single waterproof material, must be rigid and flexible combination construction, flexible waterproof stretch is good, a little settlement or deformation will not damage the waterproof layer. Rigid waterproofing (i.e., mortar waterproofing agent) can play a protective role while waterproofing, and the waterproof layer is not easy to be damaged.
