What Are Sealants?

Sealants are a type of material that is used to seal fluid against movement. They are used in the construction and the glazing industry to prevent fluids and other substances from passing through surfaces, joints and openings.

Sealant offers superior elasticity and water resistance because it primarily contains silicone as the main ingredient. This is why it makes it super beneficial for those in the glazing industry.


The Reasons for Using a Finishing Tool?

When the sealant has been applied to a crack, it will overflow causing a messy look. It is near impossible to apply sealant evenly without the need for a tool to help smooth it down. Sealants are meant to look smooth and seamless and this is why sealant finishing tools are excellent.

Owning at least one type of sealant finishing tool will be money well spent, they are super durable and can be used for a variety of different jobs.

Once a continuous bead of sealant has been applied to the area that needs sealing, smooth it down by running your tool of choice along the sealant. This will neatly trim down the sealant whilst pushing it tightly into the gap for a smooth and professional-looking finish. Minimum effort is required with one of these handy tools.

Before You Seal

Before you compete in achieving that perfect seal, it is important to remember that any worn or old seal must be removed before you continue. The old and weathered seal is likely to contain mould spores and mildew as well as not effectively holding a water-tight seal.

Sealing straight over the old seal might seem like a quick fix but it is never a good idea and your new seal will not last as long either.


How to Remove Old Sealant

A top tip to remember is that you can actually use your sealant finishing tool as a tool to help remove the old sealant. Use your tool with some silicone sealant remover as the most effective way for removing sealant. Make sure you have the right remove for the type of sealant that you are trying to remove.

Gently scrape away the silicon sealant with your finishing tool. Always clean the area well afterwards and dry completely before attempting to add the new sealant.

Alternatives to Sealant Finishing Tools

If you desperately need to do some sealant finishing and don’t have a tool to hand, do not worry. You can use your finger to press the sealant into the gap.

It is useful to moisten your finger before you do this so that the sealant doesn’t stick to your finger too much. If your finger becomes too caked in sealant you will not achieve that smooth finish. For more information on homemade sealant finishing tools then read our blog post.
