In order to make waterproof bitumen on a roof, the sodium asphalt sulfonate following process is generally required:

Before laying waterproof roofing asphalt, it is necessary to clean up the corridor above the ground, and most importantly, the dust and other materials on the exterior of the corridor roof.

Before roof construction, a layer of waterproof asphalt should be added to the railings, water outlets, pipe roots, eaves, and yin and yang corners. use it. In order to ensure the waterproof effect, the modified hot-melt asphalt coiling material can be selected in the construction.

3. After the materials are transported, the building materials related to the roof waterproofing asphalt are transported to the construction site, and then transported to the rafters of the roof.

4. When laying the waterproof asphalt coiled material, it is necessary to use a flame gun to preheat the coupling between the bottom layer and the waterproof asphalt coiled material, and it needs to be heated continuously. Assuming that the waterproofing bituminous paper only melts, then roll forward and bond the waterproofing bitumen roll.

5. The hot smelting edge of the fuel injector is heated at the waterproof asphalt joint of the coiled material, so that the waterproof asphalt coiled sodium asphalt sulfonate material is firmly connected with the outer gear, and then the end of the cladding asphalt coil is compacted and then filled with sealant.

First time using waterproof paint. After the asphalt membrane is used up, it is necessary to apply waterproof paint first. When spraying for the first time, the waterproof material supplies clean and monotonous soil. Foaming.

Second coat of waterproof paint. You will have to wait a while after the first waterproof coating is built. After the monotony, the first layer of waterproof paint is applied, and the second layer of waterproof paint is applied. The detailed time is confirmed according to the actual situation, but the interval should not be too short, otherwise the waterproof paint will definitely decline.

8. Apply a protective coating. In order to avoid damage to the waterproof layer and affect the waterproof effect, it is necessary to apply a protective coating on the waterproof layer. When laying the protective layer, it is necessary to cover it completely and not to throw it away. To avoid cracking, blistering and dropping, it is necessary to create a strong connection between the protective layer and the bottom.

After all, a 24-hour experiment with shut-off water on the roof is required. In closed water experiments, the water depth is not less than 20 mm, generally 30 to 100 mm. Assuming that the water level does not drop significantly, this means that the waterproofing roof can be modified. If water leakage is found, the waterproof layer must be repaired, and a water storage inspection shall be carried out after repairing.If you have any other sodium asphalt sulfonate questions, please contact us for details or contact us directly.
