Making A Seal
When making a seal the best working position is to hold the sealant gun at an angle of 45° and to pull the gun towards yourself. To apply the sealants neatly you need to find the right working speed. If you move too slowly you’ll get a bumpy, irregular sealant surface, and you’ll waste sealant unnecessarily. If you move too quickly you won’t get good filling of the gap. When you reach the end of the seam release the handle and press the button or lever at the back of the sealant gun. This releases the pressure so the flow of sealant stops immediately. If you don’t do this the sealant will keep coming out of the nozzle.
Finishing off the sealant line
Wet your finger with some soapy water in a dish or basin and then smooth out the seam. The soap prevents the silicone sealant from sticking to your finger. You can also apply some soapy water with a plant spray. Remove any remaining traces of sealant with the soapy water. After the sealant has dried you can remove it with a knife and a hard sponge. Special spatulas and cleaners are available to apply and remove silicone sealant.
