Putting Down Fresh Silicone

If you have used white spirit to help you remove silicone then you really need to make sure the surface you removed the silicone from is completely dry before putting down some fresh silicone.

The white spirit will prevent the new silicone from sticking to whatever surface you want it to. meaning It may just fall or peel off!

The white spirit will simply evaporate away over time. So just give it a good dry with a rag and then leave it for a few hours to make sure it has completely evaporated.
