8. FAQ

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?

A: The base material is not match for silicone sealant or there are some duct on the base material surface when use the silicone sealant. In order to avoid this happen. Before use the silicone sealant, please kindly clean the base material surface and recommend to do the compatibility test.
