Buying Guide For The Best Glue For Silicone 

Now that you have gone through all 4 products, are you able to make a choice? Something tells us you are still confused about which product to go with. Well, to be honest, we are not surprised as just the brand names, specifications, and a few pros and cons are barely enough information when buying the best silicone glue. 

You see, there are a few other factors that you need to keep in mind in order to make the right choice. The following buyer's guide will help you in selecting the product that will meet all your requirements. As such, we strongly recommend reading the entire section carefully; otherwise, you might miss a thing or two.

  1. Color Tint

More often than not, silicone glues are available in a wide range of color options. So, before buying, check the color mentioned on the package and ensure it's the same as the color of the surface on which you are going to apply it. 

However, if you get confused, simply go with the 'clear' color option, as they work well on most surfaces.  

  1. Drying Time

The drying time is a very crucial factor that you must consider when buying the right glue for silicone. In most cases, it is advisable to go for a fast-drying product so that the users don't have to wait around too long. 

That said, slow drying also helps on certain occasions, especially when there's a need to make small corrections in a project. Slow drying time allows time for moving pieces if required. So, choose as per your requirements. 

  1. Waterproof

Your silicone glue should be able to resist water, especially if it's used in bathrooms. Otherwise, water will affect the strength of the bond, and eventually, it might shrink and crack. So, before buying, make sure you check the specifications to ensure that it is resistant to water.   

  1. Versatility

Versatility is also an important factor that people often tend to overlook. Since buying silicone glue requires a significant investment, you will want to make sure that you can use it on multiple projects and a wide variety of surfaces without any difficulty. So, be sure to check the surfaces it adheres to before buying. 

  1. Steps To Glue Silicone

If you are a first-timer, you need to know the process of bonding with silicone glues. In this section, we have explained each step in detail.

  • Materials Required

You will need the following items to glue with silicone

    • Clean-up liquid
    • Soft cloth
    • Caulk gun
    • Silicone glue
  • Surface Preparation

Before you start with the process of bonding the silicone, make sure that the surface is thoroughly cleaned and free of debris. You can clean it by using water or other cleaning agents such as acetone and isopropanol. 

Once you are done cleaning, let the surface dry entirely before you start the silicone bonding process. If the surface has uneven areas, ensure that you fill them up. After that, you can prepare the cartridge and put it together with a caulk gun for use.

  • The Process Of Bonding

We strongly recommend practicing on a piece of cardboard before applying the silicone glue to the surface. If you are able to handle it properly, you can start by applying silicone beads on one side of the surface. If the surface is too big, make sure that you use more silicone glue and lay down the beads tightly.

Now, you can join the two surfaces by exerting high pressure. If you notice some silicone glue escaping, be sure to pick it up with your finger or a spatula and wipe it off using a soft cloth.    

  • Allowing It To Dry

This is the part where you wait. The drying time mostly depends on the silicone glue you have used. So, refer to the instruction manual that came along with it to know the drying time. In general, it takes about 24 hours for silicone adhesives to completely cure. 

That said, if you can afford to wait a few more hours, we suggest you do it.  

Glues for Silicone FAQs

  • What does ‘RTV’ mean in silicone glues?

    RTV stands for Room Temperature Vulcanization. If your silicone glue is an RTV one, it means it will start curing as soon as it is exposed to air.

  • Can silicone sealants be painted on?

    Unfortunately, glues for silicone are not paintable, unlike latex-based glues, also known as caulks.

  • What is the right temperature for applying silicone glue?

    For best results, it’s important to apply silicone glue at room temperature.

  • Best Glue for Silicone


    So, we have finally reached the end of our review-based guide and you know that choosing the right silicone glue is not complicated. 

    You just need to consider a few factors to make the right buying decision. But before we call it a day, we will let you in on our favorite products from this list.

    The J-B Weld is the best model overall, mainly because it sports an affordable price tag and provides a durable seal. Moreover, the GE Sealants Silicone II Household Glue & Seal is a great option if you want a product that has a low odor and is backed by a lifetime warranty.
