Ethylenepropylene diene monomer (EPDM) is a commonly used waterproof membrane, which is often used in waterproof construction of roofs, basements, toilets and other places. The following are the correct use skills of EPDM rubber:
Cleaning and preparation: Before applying, make sure the surface to be applied is clean, dry, flat and free of sharp or rough objects. The construction surface can be cleaned with a broom or electric cleaning tool to ensure that it is free of dust, oil and debris.
Cutting and positioning: According to actual needs, use suitable tools (such as knives or scissors) to cut the EPDM rubber roll into appropriate size. Lay the roll on the construction surface, positioning and adjusting as necessary to ensure correct coverage.
Seam treatment: It is an important part of waterproofing to do a good job in the seam treatment of the EPDM membrane. Generally, special seam glue can be used to seal the seam. First use a scraper to evenly spread the seam glue on the seam, and then use a flat scraper to flatten it to ensure that the seam glue is completely attached to the rubber sheet.
Edge Securing: The edges of EPDM membranes need to be secured to prevent the membrane from moving or loosening. Special edge glue can be used to fix the membrane and the construction surface together. First apply a layer of edge glue on the edge of the roll, then use a scraper to flatten it, and stick the roll to the construction surface to ensure that the edge glue is firmly bonded.
Inspection and Repair: After laying the EPDM rubber, it is necessary to carry out a comprehensive inspection to ensure that there are no trapped air or air bubbles, and to see that the joints are well sealed. If any problems are found, repair them in time.
It should be noted that during the construction process, relevant operating specifications and instructions for use should be followed to ensure safe construction. At the same time, the temperature and humidity of the construction environment will also affect the construction effect of EPDM rubber, so it should be adjusted and controlled according to the actual situation. In case of any doubt or difficulty regarding construction using EPDM, it is recommended to consult a professional waterproofing technician or consult the corresponding manufacturer.
