Seal it with silicone!

Choosing the right clear silicone

Wondering what type of clear silicone is best for your next project? Start off on the right foot and read on to find out how to use clear silicone caulk!

What is clear silicone?

Silicone sealants and adhesives are extremely versatile. They bond to almost anything and retain flexibility over a long period of time.   

Clear sealants fall into two main categories: silicone, and acrylic. 

Silicone sealant is very flexible, thus allowing for thermal expansion, and it forms a strong bond between non-porous materials such as glass and metal. However, it can be a challenge to paint over some clear silicone sealants.

Clear acrylic caulk is a water-based product, so it can be cleaned easily using ordinary tap water. It’s also virtually odorless and can be painted over.

Clear latex caulk is often referred to in DIY articles as a paintable alternative to clear silicone, but it is basically another name for acrylic. This water-based form of acrylic does not contain latex (rubber) compounds.

How to easily apply clear silicone

For best results, follow our steps below. Before starting any job, you want to prep the workspace.

  1. Failing to prepare is preparing to fail. Get everything ready before you start. For instance, try looking at cleaning instructions when your hands are covered in sealant! Some clear silicone caulk may contain VOCs (volatile organic compounds), so make sure you work in a well-ventilated space.
  2. Read the safety requirements. Gloves are recommended, as long as they don’t interfere with your work. If you do get sealant on your hands, have a paper towel ready to wipe it off straight away. This is also good for removing overspill.

Clear silicone for adhesive purposes

Roughen the surfaces. It is always best to work the contact surfaces with fine grit sandpaper first to provide more adhesion and remove any grease or dirt.

Apply the silicone to one surface. Apply evenly or in dabs. If you are using clear silicone in place of nails or screws, you don’t need a full line of adhesive.

Apply pressure. As you bring the surfaces together, you may need to use a clamp or add some weight on top.

Remove excess adhesive. Use a cloth or paper towel and leave to set.

Clear silicone for sealing

As you would with adhesive, to provide a seal, the clear caulk bead needs to be continuous.

When sealing a joint. The width and depth of the joint determine the type of sealant you can use. Packing can be used behind a deep joint if necessary. Always check the instructions.

Tidying up

Paper towels are best as they can be disposed of afterwards.

Remove all sealant from visible surfaces. Do this before it starts to set (usually within 30 minutes).

Remove residual sealant. Once cured it can be a challenge to get silicone off, so a special removal tool may be necessary for large areas. Isopropyl alcohol is also useful.
