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 Apply silicone sealant to the gap
2 Wipe off the excess silicone
  • Step 1. Apply silicone sealant to the gap

    To give the silicone the best bonding surface possible, clean and dry all your surfaces before you start. Then use the caulking gun to apply silicone to the gap, working smoothly and evenly. Don’t worry if it looks a bit rough, you can fix that in the next step
  • Step 2. Wipe off the excess silicone

    Use a damp rag over the tip of your finger to wipe along the newly sealed gap. This will wipe off any excess and push sealant further into the gap to help give you a neat finish. For tight corners, use a chisel to neaten the edge. Clean off any excess with the rag.
