3.APPLICATION OF GNS® HIGH-TEMP 265℃ SILICONE SEALANT
--Thoroughly clean and dry surface from oil, dirt and grease. Allow to dry completely before applying silicone.
--Cut the seal at the top of the cartridge and cut the nozzle at a 45° angle, to the size of the gap opening. Screw the nozzle to the top of the cartridge.
--Place the cartridge into a caulking gun.
--Hold the caulking gun at a 45° angle. Press the nozzle opening against the joint, apply steady pressure to the caulking gun and extrude the silicone sealant forcing the sealant into the gap and move in a pushing motion, along the joint in one smooth action.
--Sealant will cure fully in 48 hours. As this point any unwanted sealant can be removed by trimming with a sharp blade, but avoid under cutting the seal.

6.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 impact of silicone sealant with bubble?A. No bubble on the silicone sealant surface is a common performance for a good quality PU foam; if the silicone sealant has bubble, the silicone rubber is easy to break after curing.
