Why using a silicone caulking nozzle spatula results in clean corner finishes

When performing silicone work, many people experience difficulties because the corners become unevenly protruding or the finish is not clean. According to a video from the YouTube channel Jipsuritong, when using a standard silicone gun, beginners often struggle with insufficient finishing, making the work results look messy. To solve this, a method utilizing a 'silicone caulking nozzle spatula' was introduced.

Features and selection methods of the silicone caulking nozzle spatula

The silicone caulking nozzle spatula is a tool designed to be attached to the front part of an existing silicone gun. The presenter in the video explains this product as a 'two-piece glue nozzle set' and states that it is useful for window sealing or working on angular corners on both sides. When selecting a product, one must check the 'R-value.' The R-value refers to the size of the finished round, and the video mentions that a larger number, such as 13R, results in a larger round being formed. The products are divided into about three types, allowing for selection based on the work environment.

Smooth finishing method using the nozzle spatula

The usage is simple. After cutting off the front part of the silicone gun you were previously using, you can attach the prepared nozzle spatula in its place and use it. The video compares the uneven finish that occurs during general silicone work with the difference when using the nozzle spatula. If silicone is applied in the conventional way, the ends come out uneven, but if you push it while maintaining a constant angle with the nozzle spatula attached, a much smoother and sleeker curved finish is completed.

The presenter advised that while there are various ways to make corner work clean, such as shaving the surface or using fire, it is efficient for beginners to use specialized tools. This tool is good for use in places where corner finishing is important, such as bathrooms, and having one on hand allows for convenient use during repetitive corner work.
