How to apply silicone sealant

Silicone sealants are a useful product to have around the house. They are a strong adhesive that can be used to seal windows to frames as well as been used in appliances and even cars. The reason for this is that sealants are extremely powerful and resistant to adverse weather conditions meaning that rain and wind will have no effect.

Additionally, the sealant also works in high-temperature conditions making them ideal for repairing oven doors and windows in warmer climates.

What do I need before applying the sealant?

As previously mentioned, you will need the silicone sealant, rather than canned sealant. You will also need a silicone gun. This is a medium-sized plastic product in which the silicone sealant tube is placed. The gun has a trigger function that allows the user to apply the product.

What steps are needed to apply a sealant?

There are several steps to undertake to apply the sealant. Firstly, you will need to make sure the surface on which you are applying the sealant is clean. Dirt or dust could affect the success of the adhesive and affect its longevity. To clean the surface, you can use some soapy water and a sponge and wipe the surface. Then thoroughly dry the surface with a towel. Having done this task, you can begin applying the sealant using the following steps:

• Push the gun’s release tab and then pull up the pressure valve – which is the long metal contraption at the back of the device. Once pulled, you can insert the silicone sealant.
• Place the silicone in the gun and apply pressure to ensure it is firmly in place. The nozzle of the tube will be sticking out of the other side of the gun if inserted correctly.
• Ensure that the trigger of the gun is calibrated with the tube’s size. To test this, you can squeeze the trigger slowly and this will adjust the tube into place. From here it will be locked in position.
• Following this step, you need to create a hole at the top of the silicone tube so that the substance can be squeezed out by the gun. Make the insertion as close to the nozzle’s tip as possible. Scissors would be preferable for this job, however, if need be you can use a knife. Make sure you are taking your time and acting carefully when using a knife to avoid injury.
• Before applying the sealant to your window, for example, you should test it on a piece of excess metal. This way you can make sure there are no surprises.
• Carefully pull the trigger on your gun and apply the sealant to the chosen surface. Slowly pull the gun along and this will create a neat line. You can even wet your finger and spread the sealant out evenly to ensure that it covers all the area you want. Alternatively, use some masking tape and place it on the bead line. As long as you pull the tape away before the adhesive becomes tacky this is an effective way of spreading the sealant evenly.
• Finally, give the sealant enough time to dry. It may feel dry after 30 minutes, but we recommend waiting at least 24 hours before using the window or appliance. Using a hair drier or fan can speed up the process however 24 hours should still be the target.
