This is an excellent sealant and adhesive for anyone looking to do repairs or DIY work. It is designed for repairing anything from broken soles in your shoes to damaged insulation on cables.

While we cannot find a specific release date, we know that Loctite has been providing products of this nature for over 50 years now. They are known globally, and their products are trusted and recommended.

Who Is This Product For?

It has many applications and uses, and it requires minimal effort on your part as the user. All you need to do is treat it as you would any other superglue: gently squeeze and spread it on the area you want sealed. This easy-to-use product and its low price make it an excellent choice for anyone, not just professionals.

What’s Included?

Purchasing this item comes with the adhesive and an additional nozzle for finer sealing. Otherwise, there isn’t anything else you need to use this product. It works like any standard sealant would and is very user-friendly because of this.

Overview of Features

Loctite Clear Silicone is a 100% pure silicone sealant and adhesive. It is perfect for waterproofing and repairing gaps, cracks, and breaks in a variety of items and materials. It is a tried and tested sealant that many recommend for indoor and outdoor use to waterproof and weatherproof, as well as make repairs.

As a completely silicone-based sealant, it comes with the standard features of strength, flexibility, and being waterproof. It works and binds well with metal, ceramic, porcelain, and glass. Also, it is immune to cracking, peeling, or changing based on temperature. Its durable nature makes it well-suited for use in just about any situation. It can be applied in any season at any temperature and is excellent for imperfect surfaces.

If you’re instead looking for a sealant for filling gaps or waterproofing joints between tiles, a silicone-based caulk might be a better option.


Owing to the rather simple nature of this sealant, there isn’t a tutorial in the traditional sense. The way one uses Loctite Clear Silicone is like you would any other form of tubed adhesive and sealant. Gently squeeze the tube until the clear liquid comes out of the nozzle and then spread this liquid over the desired area.


  • It dries to be completely clear
  • Sealant remains durable under extreme temperatures and weather conditions
  • It is temperature resistant and won’t crack or peel due to shrinking and expanding with temperature changes
  • The sealant is multipurpose and can be used as a sealant on multiple surfaces


  • Some types of plastic are incompatible with Loctite Clear Silicone
  • It takes up to 24 hours to fully set


If some of the drawbacks of the Loctite Clear Silicone are too much for you, you’ll want to look for other options to this brand. While this is a fantastic product, it isn’t perfect, so here are some alternatives that can do things that Loctite Clear Silicone cannot.

Gorilla 100% Silicone Adhesive

Gorilla 100% Silicone Adhesive is a fantastic alternative that is just as versatile as Loctite Clear Silicone. It works well with any and all surfaces, except for wood. It also features the same easy-to-use design with a similar tube and nozzle that Loctite Clear Silicone uses. Thus, it will feel familiar to the user. The only downside is that this is not too great when working with wood.

Anti-Seize RTV Silicone Sealant

Anti-Seize RTV Silicone Sealant is another alternative that many recommend and swear by. Featuring the same level of versatility and strength, it can be used on basically any surface, including plastics and wood. Those are the surfaces that Loctite Clear Silicone and Gorilla 100% Silicone Adhesive cannot be used on. It comes with anti-seize material and can be used indoors and outdoors without worry.

It responds well to heat, shock, impact, moisture, and vibrations. Its only real weakness is that it may crack when put under too much torque. Otherwise, if you still aren’t sold on Loctite Clear Silicone, then this is the next best option. According to many, it may actually be the better option.


To make a final pitch for Loctite Clear Silicone, this adhesive is a versatile and robust sealant. It is only matched by other top-of-the-line sealants from other big name brands. This naturally puts it in an excellent position as one of the best silicone adhesives on the market.

Able to fulfill almost any task, it can be used to make repairs to damaged wires or glue the sole of a shoe back on. It can also repair cracks in window panes or even be used to seal the joints of a small fish tank. With Loctite Clear Silicone, you are guaranteed impressive quality.
