6. The wall shall be solid, waterproof, dry, smooth and clean.
If it has been eroded by mold, it should be cleaned first and the pollutants eroded by mold should be removed
7. Do not add too much water during thinning construction with clear water to avoid construction sagging, dry film powder removal and covering Poor force and other defects.
8. Please wash and dry the tools immediately after use,

9. general interval construction coating time to 6~12 hours/above 25℃, depending on the specific construction environment and to Stop construction when the temperature is lower than 5 degrees;

10. If spraying on smooth objects or other plates, it is recommended to spray one layer of special transparent seal first.
It depends on the thickness.Primer, after the primer is completely dried (24 hours /25℃), spray sound-absorbing and sound-insulating paint topcoat Implement relevant national standards Sound absorption; GB/T16731-1997 code for measurement of sound absorption coefficient by chamber method GBJ47-1983 classification of sound absorption performance of building sound absorption products GB/T20247-2006 sound absorption measurement of acoustic reverberation room
