Silicone Bonding - A versatile sealing option

Gluing with silicone is used in many areas. This is especially due to the good properties of silicone. It is easy to apply and can be brought into the desired shape. In addition, it is very resistant to heat, cold and moisture. It is ideal for filling and sealing joints. These include, for example, the joints between tiles. The new sealing with the silicone can be necessary for many reasons. It may, for example, the old joints have been repainted or even new joints have been misplaced. Regardless of the reason of the application, there are some helpful tricks when using silicone.

The following sections explain the procedure with silicone adhesive and give valuable tips in dealing with it.

Preparing the application area

Before starting the actual work comes, some preparations have to be made. This includes, among other things, the cleaning of the application area. Silicone is often glued in joints of tiles. Since these are in kitchens and bathrooms, it can often lead to grease or oil residues. Dust and liquid can also influence the adhesive properties. Therefore, an extensive cleaning is essential. Then the cleaned area should then also be dried. Another preparatory step may be the measurement of the joints. The width is especially important for later steps. However, the survey can also be helpful in estimating the total amount of silicone.

Get a little too much silicone, rather than too little. Interruptions in the work can lead to premature curing of individual sections.

Preparations for the silicone spray gun

The silicone spray gun must also be prepared first. It is a tool that allows the silicone to be applied evenly and precisely. Although the preparation may depend on the model, it is usually necessary first to insert a cartridge with fresh silicone. This cartridge can be opened with a cutter knife or similar. In some cases, then a top must be attached to the top of the cartridge. Then the cartridge can be used and the attachment can be cut to the correct size or width. Under certain circumstances, the correct size was already measured in the preparations and should correspond approximately to the joint width.

The choice of silicone should be made depending on the intended use. Especially damp rooms need special materials.

Applying the silicone

A skilled handling of the silicone spray gun, as well as a feeling for the exit speed of the silicone are recommended at this time. The application itself requires first and foremost a steady hand. The silicone spray gun must first be applied at the desired location. After that, it is particularly important to spread evenly. Failure to do so can lead to unwanted clumping in individual locations. These points must then be subsequently improved. When applying the silicone can also survive a piece. This makes it possible for the silicone to spread out later and as much as possible to cover all areas. After use, some models recommend relaxing a spring in the gun.

Adhesive tape can be used to correct irregularities in the application. To do this, simply tap beforehand and peel off afterwards.

Further processing of the silicone with a finger

After the silicone has been roughly applied from the gun, it must be further processed. There are several possibilities. For one of the two options, only household items are needed. A spray bottle should be filled with water and detergent. Then the silicone can be sprayed with it. Then the silicone can be easily distributed with your finger. For this you only have to move the finger evenly over the place with your finger.

The mixture of detergent and water prevents the silicone from adhering to the finger. If in doubt, the finger can also be sprayed again with the mixture. The pressing is intended to ensure that the silicone completely covers and fills the joint. So a good seal should be achieved. Caution should be exercised as some silicones are poorly tolerated by the skin. Please observe the instructions on the packaging. In these cases, use the following method.

Working with a silicone puller

There is also the slightly more professional version. Here, a silicone puller is used instead of the finger. The principle is the same. This too is used for smoothing the previously applied silicone. This is an advantage for skin-incompatible silicones. Even with the puller, the mixture of detergent and water is needed. It is also important to apply the silicone evenly and finally. Afterwards, it is easy to remove excess residues. For this purpose, knives are particularly suitable in marginal areas. The silicone must then first dry out and then be cut off later.

Before using and loading the newly glued area, it is essential to observe the curing times of the manufacturer!

Conclusion and final assessment

Gluing with silicone offers many possibilities , In particular, the properties are given for sealing. It is in the form of the silicone spray gun while also somewhat more professional material needed, however, the work steps are very easy to perform and require only a short settling time.


The sealing of joints is to implement with the help of silicone. It only needs to be applied and later distributed in a sealing manner. The effort is very low with the time required for drying.
