Sealant finishing tools are exactly what the name suggests, a tool used to finish off your sealant. These tools are typically plastic and designed with specific angles for use on all sizes of sealant gaps. This includes smaller sizes for use on standard joints and larger sizes for joints bearing excessive loads and pressure. At GGR Glass we have been trading for almost 30 years and have a range of all the best glazing tools on the market. Below we discuss the best ways to use sealant finishing tools.

What to Avoid

Although finishing sealant may seem simple there are plenty of areas you can go wrong if you are inexperienced or are sealing something new.

Homemade Sealant Finishing Tools

Although this is a cheap and quick alternative to going out and buying a new sealant finishing tool it can cost you more in the long run. Homemade tools can leave a lumpy and patchy finish on your joints which at best can result in an unattractive finish or at worst can result in leakages and mould along your window or bath sealant edges.

Don’t Leave Old Sealant

While it may be a quick fix to put sealant over the existing silicone it may end up covering existing issues. If your old sealant is mouldy then it is very likely mould will grow through the new sealant too. Or if it is patchy the new sealant will struggle to hold onto the sealant and fall off or become patchy as well.

Don’t Use the Wrong Size Tool

Sealant joints vary in size which is why most sealant finish tools have a range of angles to accommodate this. Using the wrong size tool can mean that you might not achieve a tight seal which can cause leaks. Our Sealant Finisher Tool Set however contains four different pieces which can be used to finish up to 16 types of joints.

How to Get the Perfect Finish with Your Sealant Finishing Tools

You should start by removing any old sealant and cleaning up the area to ensure the new sealant will stick.

After setting up your sealant and sealant gun test it on some scrap material so you can get used to the flow.

Once you feel confident apply the sealant from one end of the joint to the other.

Now the sealant is applied grab your sealant finishing tool and ready the corner with the size you need.

Press your tool against the sealant and run it along the entire length. You should maintain even pressure to ensure a slick finish.
