Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement needs that require external wall waterproofing and leak repair, it is recommended to prioritize confirming the material's UV resistance level and tensile strength. For high-rise buildings, more weather resistant elastic coatings should be selected.
  • When construction is carried out in humid and rainy areas, attention should be paid to the adhesion and permeability parameters of the product to avoid secondary detachment caused by the moisture of the base layer. Targeted selection is required for scenarios such as basements and balconies.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information.
  • For different base surfaces such as concrete or ceramic tiles, it is necessary to distinguish between using permeable or film-forming waterproof materials. It is recommended to use base treatment agents for repairing old walls.
