Review ended –

This was the end of the whole product review section and if you have come so far, I am sure that you might already have decided at least one product for your own purpose.

So, which caulking is best for a shower?

If you are still deciding, then let me share more information with you about the shower caulks.

Yes, wait a minute!
Let me talk about different types of shower caulk. So you would have a better understanding of the product.


Different Types of Shower Caulks

This is an essential bit that we cannot fail to address when it comes to choosing the best caulk for shower.

You would wonder to know that!

For most people, they only know of the silicone caulks, because these are quite popular. As a matter of fact, most shower caulks will either be made of silicone or latex.

But, yes some companies have broken this limitation for you!

They have ventured into making caulks that are a combination of latex and silicone. Let us look at the different types of caulks, so as to gain a deeper understanding:

1. Silicone Caulks

The most common type of shower caulk and is preferred by many users due to the numerous benefits that it carries. This type of caulk is waterproof and quite flexible, irrespective of the temperature.

Silicone caulk is usually highly resistant to mildew and mold and bonds easily, with most surfaces. The silicone caulk comes in two different types:

  • Neutral Cure: This is ideal for wood and metal surfaces.
  • Acid Cure: You will need to use this one for nonporous surfaces like glass or glazed tiles. Acid cure silicone can corrode metal and may also cause damage to plastic materials.

Caution: Silicone caulk is the best option for your shower, but it is worth noting that it will not hold paint. As long as it has been applied in the right manner, it will hold in place for a very long time.

2. Latex Caulk

In recent times, latex caulk has gained popularity, especially among DIYers. It is said to have a lifespan of up to 20 years when it is applied properly. It is quite flexible and offers the convenience that you can paint it over to match any surface that you desire.

So, latex caulk is considered among the best paintable caulks around the market. This is ideal for interior use as you will not have to worry about your interior decor. Latex caulk is easy to use and you can have it at home to fill up cracks around the house.

Caution: Unfortunately, latex caulk does not adapt well to temperature changes. This may not be the best option for your shower but will be suitable for door and window frames, as well as wood sliding.

3. Polyurethane Caulk

This is another type of caulk that is ideal for outdoor tasks. It comes with a lot of benefits like the fact that it adheres to almost any surface, it is tear resistant and also non-corrosive. So whether you are using it on metal surfaces or glass, you can be sure that this is a good choice.

It is quite flexible when it comes to the application, as opposed to silicone caulk. If you are looking for caulking that is waterproof, durable and has superior attributes, then you should consider polyurethane caulk.

Caution: The only drawback is the fact that it is not resistant to UV rays and as such, it is advisable to apply a coat of paint on the joints that are exposed to UV rays. As far as pricing goes, this is the most expensive of all the other types.

4. Specialty Caulks

Specialty caulks are designed to serve specific purposes. This type of caulk will vary, in terms of the price, depending on the specific one that you want. Here are some of the specialty caulks on the market:

  1. Roof sealants.
  2. Caulks for doors and windows.
  3. Mortar caulk resists high temperatures.
  4. Shower caulk with properties to resist mold and mildew.

Caution: Just remember that this caulk might not serve all the caulking purposes, meaning that this one is NOT appropriately multipurpose.


These are the different types of caulks and it is advisable to be familiar with each one. This makes it easier to pick the ideal one for your shower.

Now, you should have a look at the important points that are to be considered before buying a shower caulk.


Things to Consider When Shopping for Shower Caulk

There are a number of factors you need to know and that will help you pick the ideal shower caulk.

Caulk for the shower is ideal for anyone would want to prevent mildew and mold from growing in the walls.

Here are some of the key considerations to inform your decision and help you find an appropriate caulk for the shower:

  • Surface to be caulked:

    There are certain caulk products that will work better than others, depending on the surface. As such, it is important to consider the material of the surface so that you can pick the right caulk.

  • Temperature Variation:

    Is the area being caulked subject to different temperatures? You should find caulk that can be able to withstand the specific temperature in your shower. For instance, latex caulk may not withstand extreme temperatures, like silicone caulk.

  • Moisture and Wetness:

    Bathrooms are prone to be moist and wet most of the time. This is a vital consideration and in this case, you will need to find caulk that is waterproof and can resist wetness. Such caulking products will also be highly resistant to mold and mildew.

  • Location to Apply Caulk:

    The other factor that you need to bear in mind is the exact location where you will be applying the caulk. This allows one to pick the best caulk to be able to handle any movements of the joints and other elements.

  • Application Process:

    There are some caulks that are easier to apply than others. Also can be cleaned easily, after application, while others will require strong solvents to clean up. While at it, you may want to consider the odor that the caulk emits during the application.

  • Price:

    Finally, just like any other shopper, one has to consider the price of the caulk. You should have a budget in mind when you go out shopping. There are types of caulks that are more expensive than others. However, while looking at the price, it is critical to note that some of the caulks are expensive because they have superior strength.

With these pointers, it should be easier for anyone to narrow down to the choices of the shower caulk that will work best for your case.

Have a look at some trending topic of shower caulk products.


Dap vs GE silicone caulk

Let me discuss the specifications of the two different types of caulk –

GE Silicone:

Among the silicone versions, GE is one that is silicone based caulk, especially for your shower and kitchen. It has two different types that –

  1. Contains mildewside, which is for your “Kitchen and Bath”.
  2. Without mildewside, this is for your “Windows and Doors”.

Mildewside containing caulks has high waterproof and mold protection capability that has made it a widely used caulk for shower and kitchen surroundings.

And as you use the caulk in your shower tile gaps, bathtub surroundings and sink joints, doors and stall areas where you need not painting. If the GE is 100% silicone then you will not be able to paint over.

But also, some are paintable caulks that are silicone based. That you may use around your doors and windows. So, the multipurpose versions are popular too.


Dap caulks are longer lasting and mildew protective. It is water resistive and has very low odor. Combination of latex and silicone has made it paintable that you can start painting over in just 30 minutes. It has the ability to cope up with high temperature that reaches from 20-120 degrees.

Applying it in your chimney surroundings is a better use of the caulks. They are easy to apply both for indoor and outdoor uses.


Silicone vs Acrylic caulk

Both silicone and acrylic caulking seems to serve the same purpose.

However, there are some differences in terms of the quality of the caulking. We will look at the pros and cons of each so that we can have a clear picture. Let’s dive right in and spot the differences.

Silicone Caulking

Silicone caulking is known to adhere and last for a very long time. Once you have finished sealing any cracks or caulking your applications using silicone-based caulk, then you can rest assured that it will not distort.

This is one of the best options for your bathroom as it creates a waterproof barrier and will also keep moisture out. Some of these traits, like inhibiting moisture is what makes the silicone based caulking an ideal choice even for outdoor use.


  1. Comes in different colors
  2. It is elastic and as such, it adheres well to any surface, as long as it is smooth
  3. Has the capacity to repel moisture and ideal for places where there is a lot of moisture in the bathroom, laundry room, and the kitchen area.
  4. Can tolerate movement on joints due to its elasticity and will not distort.
  5. Besides being waterproof, silicone caulking is also heat and cold resistant.


  1. You cannot paint over silicone due to its ability to repel moisture


Acrylic Caulking

There are some people who prefer to use acrylic caulking due to its ease of use. At the end of the process, you will have very clean and neat caulking, with the use of acrylic caulking. This is best suited for the ceiling, woodwork trim, painting applications as well as walls.

Acrylic caulk can be used to seal gaps and cracks in your windows and doors. As far as prevention against water and moisture, this may not be the best option as it will peel and distort after a while.


  • Acrylic caulk dries up much faster than the silicone based caulk.
  • Before drying up, you can actually remove it with a damp piece of cloth.
  • Ideal for filling gaps in places like skirting boards, furniture and picture rails.
  • You can easily apply varnish or paint over acrylic silicone.
  • When it dries, it is actually harder than the silicone caulking.


  • It is less tolerant and cannot be used in places where there is movement
  • As it dries up, it will shrink and in most cases distort
  • It is not water resistant

 So, if you are looking for an option to repel moisture and protect your home from the wet weather conditions, the best choice would be silicone caulking.

However, when you choose to use silicone-based caulk, you cannot paint the surface as the paint will peel off.

Seeing that each has its own pros and cons, it will really depend on what you are caulking. Over and above, silicone based caulking has so many advantages and appears to be a lasting option. Silicone caulking is quite versatile and is more reliable.


So, why is a Shower Caulk Essential?

There are a fair number of homeowners that assume shower caulk is for aesthetics only. While this may be true to a certain extent, there is a bigger role played by the caulking.

When you have tile walls in your shower, there is a very high possibility of water leaks between the bathtub and the tiles. When water gets into the crevices, the damage can be unimaginable. This is why you should re-caulk your shower, annually, as part of the maintenance process.

It is essential for your bathroom to prevent mildew and mold in your bathroom. You know how frustrating the mildew stains can be and the best way to get rid of mildew is by using a high-quality shower caulk.

Clearly, it goes far beyond the aesthetics of your bathroom and is essential.


Now, head over to some asking questions that might give you some mind-blowing information to note down.


Frequently Asked Questions

1. Question: Is it okay to apply a new caulk over an existing one?

Answer: This is not advisable and we highly advocate that you should remove the old caulk before applying a new layer. When you apply it over old caulk, the bond will not be as strong as applying it to the surface directly.

2. Question: Do caulk products expire?

Answer: Certainly, everything that is manufactured has an expiry date and as such, caulk products will also expire. Remember to check the expiry date while shopping, otherwise you may end up with one that has gone bad and will not give you the desired results.

3. Question: What is the proper way to store my silicone caulk?

Answer: Once you are done caulking, you should ensure that you push out all the air out the nozzle before placing the cap back on. The cap should be locked tightly and the silicone caulk needs to be stored in a cool place.

4. Question: What is the difference between caulk and sealant?

Answer: Although these terms are commonly used interchangeably, there is a difference. Generally, caulk refers to general products that usually fill in gaps and have low contraction and expansion qualities. They are best suited for interior use and have a moderate adhesion.

Sealants on the other hand, are said to have superb adhesion properties and will adhere to most surfaces. They withstand most weather conditions.

5. Question: How long will it take for the silicone caulk to cure?

Answer: There are different products that come with different curing times. However, the average time that a silicone caulk will take to cure is 20-24 hours. The moisture in the air will influence this time significantly.

6. Question: Does caulk products vary depending upon calking gun?

Answer: Well, almost all the caulking guns are designed in such a way that they allow all kind of caulk tubes to fit in. But, there are some caulks that do not need any caulking gun like the peel and stick caulk or, caulk stripe seal.

7. Question: What if my old caulk tube gets cold and becomes hard to squeeze?

Answer: It can happen for cold weather. So, you can try to keep the caulk tube in softly warmed water for about 20 minutes to see if is solved yet.


Field of Uses of Caulk 

Whether you have a silicone or an acrylic caulk, you can use it for a wide range of applications. In most cases, caulks are used to seal gaps in showers, bathrooms, countertops, kitchen backsplashes, walls, attic, chimney, windows and doors among others.

So, not only the shower but also caulks are also applied for many other purposes too.

While the field of uses can be quite diverse, it is essential to note that the different types of caulks will have different uses. This is an essential product for most repairs and maintenance tasks.

For shower caulk, you should stick to the silicone-based caulks, as they are quite effective.

On the other hand – for the kitchen, you should consider that the temperature may vary as of when you use the kitchen and when not.

So, in this case, you should use a caulk that can cope with the kitchen environment.


Bottom Line
When you have to buy caulk, it is important to be very clear on the specific use. Some will be better than others, although they are almost close to each other. But still, each one comes with its unique benefits.

The common caulk, as we have already established, is acrylic latex and the silicone caulks. There are those that will be made by combining both latex and silicone to enhance performance.

Getting a caulk that can be used in an extensive range of applications is advisable as this will serve you in different areas. Shower caulking is a critical process that ensures that you have a safe and clean environment.

Silicone caulks are highly recommended for use in the shower, as they have a high resistance to water and moisture. When you are keen on finding the best caulk for shower, you will need to consider all the factors that we have discussed so far.
