Finish silicone

To give silicone a smooth finish, some people use a bit of saliva on the end of their finger. Then six months later they wonder why their silicone has started to go mouldy. The bacteria in your mouth will happily grow in silicone, which creates those darks stains. To get a smooth finish that won’t discolour, use a wet rag dipped in fresh water instead.

Step by Step Instructions

1 Scrape inside the gap
2 Cut along where the silicone joins the wall
3 Wipe the surfaces clean
  • Step 1. Scrape inside the gap

    Use a flexible plastic or metal blade to scrape out the deeper silicone. Push and pull the blade backwards and forwards between the gap. The silicone will grip the surface of the blade and start to come loose. 
  • Step 2. Cut along where the silicone joins the wall

    Use a sharp knife to cut along the length of the silicone and separate it from the wall. Then run a flat-blade chisel in between the silicone and the wall to get rid of as much silicone as possible. It might not all come up in one go, but you will get the bulk of it out this way.
  • Step 3. Wipe the surfaces clean

    Once you have removed most of the silicone, wipe the remnants off using a cloth. You can make the job a bit eaiser by soaking the cloth in methylated spirits. The methylated spirits act as a solvent, breaking down the last of the silicone, making it less sticky and easier to wipe up.
