Q: What’s the reason that after used Neutral silicone sealant, there are some bubble on the surface?
A: When use the silicone sealant into the gap, the gap is damp, after the sunlight contact, it will make the steam effect the un-cured silicone sealant. That’s the reason why there are some bubble on the silicone surface.Q: What’s the reason that after the silicone sealant cured, it will be crack out of the base material?
