A buyer’s guide is important to inform you of a specific type of product and what you can expect from it. This will help you when you are looking for that certain product and the right one that suits your needs.

It is better to look around and ask questions regarding that specific product and the special features included with it. All products are not made equal and have their own specific characteristics that make them differ from each other.

It is these features we are looking for that makes them perfect for the purpose it is needed for.

For what Surfaces is it Suitable?

Silicone caulk is mostly used to seal off cracks and small spaces where water can seep through to make it water-proof. It is also used to seal cracks in walls where insects or cold air or heat can come in.

It can be used on glass or any type of metal as well as plastics to create a bond between two surfaces. Quite a common application of silicone sealing is in the use of making fish tanks water-proof by joining the corners of the glass.

It can be used on many types of surfaces as long as the surface is adequately cleaned and dried from moisture.


Even if you are not able to paint over silicone caulk, they are available in a wide variety of colors. You are able to color most silicone caulk with a water-based coloring if you want to change the color.

To be on the safe side, it is always better to get professional advice in the coloring of the silicone caulk sealer. Some manufacturers made the job of coloring the silicone sealer much easier for you by supplying a variety of colors.

But this extra feature comes at an additional cost, and the problem is that you are stuck with the available colors.


Silicone caulk sealer comes in a standard size of 10 ounces, but they are available in some other sizes as well. Some manufacturers will supply containers and cartridges in sizes that are enough for a specific job, and you get just enough.

There are other commercial sizes available as well, such as 29-ounce cartridges. The problem with the much larger containers is that you will need to buy a larger caulking gun to use it with.

There also are much larger containers available for use on construction sites and other bulk uses of silicone sealers.

Water Resistance

Silicone caulking sealers are the most common type of sealers used in the industry to achieve a water-proof effect. They are very flexible and can be used in extreme weather for external water-proofing applications on a variety of materials and surfaces.

They can be used in many types of places and on many types of materials where a watertight seal is needed. Silicone has a high heat resistance as well as a complete water resistance for a 100% sealing effect.

The high water-resistance characteristics of silicone are the main reason why it is so effective in sealing water pipes and other plumbing.

Mold And Mildew Resistance

Silicone caulk sealants are commonly used in the water-proofing of plumbing and bathrooms because of the presence of moisture where mold may appear. Even where silicone is used, mold or mildew may grow when there is moisture around or on it.

There are a few ways to prevent mold from growing on silicone, which involves chemicals that are anti-bacterial to kill it. Or you can just buy a silicone caulk sealer that is already treated with the chemicals to prevent mold growth.

Mold-resisting silicone is normally not a food-grade silicone and can not be safely used with kitchenware or where food is prepared.


How To Open a Silicone Caulk Tube?

To open a caulk tube, cut open the tip by using a utility knife or tip cutter included on the caulk gun. For a more precise application of the silicone bead, you may cut the tip of the tube at a 45-degree angle.

To open the seal that lies behind the screwed-on tip at the top of the tube, use the built-in rod. This rod is integrated at the front end of the caulk gun to make it much easier to break the seal.

You may also use a long nail that is strong enough to break the seal when you push it through the tube nozzle.

How To Apply Silicone Caulk?

To apply the silicone bead to the job, you need to put it inside the cradle of the caulk gun. Then by holding the point of the tube close in place, apply pressure to the caulk gun trigger to push forward.

With the nozzle close to the place where you want the silicone while pressing the trigger, move the caulk backward. This will help to evenly apply the silicone to where you want to seal or bond with other material.

After application of the silicone, wet your finger and lightly run it along the silicone strip. Remember to release the caulk gun trigger when you get close to the end to prevent the silicone from running out.

How Long Does Silicone Caulk Take To Dry?

Some silicone caulk sealers may dry quite fast, and others may take some time to cure before they are completely dry. The humidity levels in the air may also influence the speed at which the silicone may dry completely.

According to the experts, it is better to give the silicone 24 hours to completely dry before it is exposed to water.

Is Silicone Caulk Paintable?

In the case of most standard silicone caulk sealers, the paint will not bond with the surface of the silicone. There are specially treated silicone caulks that may be able to allow for it to be painted over with certain treatments.

You may apply a thin layer of silicone latex over the sealer that will allow the sealed area to be painted.

How Do You Smooth Silicone Caulk?

After the application of the silicone caulk bead to the place you want to seal, you can spray some denatured alcohol. You can now use your finger to lightly smooth all along the line of silicone before the alcohol is dry.


All these silicone caulk sealers are a great choice for your needs. However, the GE012A all-purpose silicone sealant caulk is the one that stands out more than the other types.

The fact that it can be used in many applications makes it quite the favorite sealer. It can be used in extreme weather and will resist for a long time.

Now that you have the information you need about silicone caulk, you can ensure that any sealing needed in your kitchen or bathroom can be taken care of quickly, easily, and properly the first time around.
