If there is no such report, the Contractor shall be urged to immediately entrust a testing agency with such qualification to carry out special test, and the qualified test can only be used.

Light color, color, transparent sealant has poor UV resistance, which is only suitable for indoor engineering; generally, black sealant should be used outdoors. The environment for storing glue shall meet the requirements of temperature and humidity to ensure a longer service life of sealing.

Building sealant has the function of waterproof and sound insulation. Waterproof is very important. It will often be washed by rainwater. In terms of sound insulation, sound insulation materials will be selected basically. In this respect, the requirements are not very strict.
