Who knows how the elevation of SBS waterproofing membrane is rolled up?

The base is a cement mortar screed-coat, which must be solid and flat, without looseness, bulging, rough surface and inequality, otherwise it must be treated. The base must be dry, and the moisture content should be within 9%. During the test, the coiled material is laid on the surface of the base, and after 3-5 hours, if there is basically no water drop on the lower surface, the construction can be started.

Before construction, carefully clean up the cement mortar residue, dust and sundries left on the surface of the base, and then coat the bottom oil evenly, and dry for more than 8 hours at a time (depending on the temperature, it is advisable not to stick feet). Treatment of complex parts: the corner of yin and yang should be made into a figure of eight, and the corner parts such as parapet, pipe root, chimney, exhaust hole, water outlet and expansion joint should be made into additional layers. , generally 30cm wide, overlapping 6-8 cm.

Precautions:

1, construction should pay attention to the construction environment, especially the temperature, to ensure that it is below -5 degrees, so as to ensure better construction effect. When the full paste method is adopted, the use temperature of SBS waterproofing membrane should be controlled above 5 degrees.

2. Additional layers shall be made in special parts during construction.

3, but also to ensure that they are neatly arranged and cannot be bent. After the construction is completed, we have to wait for a few days to conduct post-construction inspection to ensure that the construction is qualified.

4. In the construction of SBS waterproofing membrane, we must first understand the characteristics and adopt reasonable construction methods according to the characteristics to ensure the best construction effect. In addition, attention should be paid to avoid exposure and extrusion during transportation, and SBS waterproofing membrane should be stored in a relatively dry environment.
