From making windows airtight to filling in the gap between the bathtub and the wall, applying silicone is hugely satisfying. Not only are these gaps unsightly, but they also become perfect places for mould and mildew to creep into and take hold.

The best way to combat both of these problems is with fresh silicone, which can be satisfying both in the knowledge of a job well done, and in seeing those gaps getting steadily filled in by smooth, clean lines. For best results apply masking tape to cover both sides of the line to be sealed, apply the sealant across the area, smooth out and then remove the tape before the sealant is dry.
