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:
- Roof sealants.
- Caulks for doors and windows.
- Mortar caulk resists high temperatures.
- 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

Caulk for the shower is ideal for anyone wants to prevent the growth of mildew and mold on 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.
Is the area being caulked subject to different temperatures? You should find a 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:

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 topics of shower caulk products.
Dap vs GE silicone caulk
Let me discuss the specifications of the two different types of caulk –
Among the silicone versions, GE is one that is silicone-based caulk, especially for your shower and kitchen. It has two different types that –
- It contains mildewside, which is for your “Kitchen and Bath”.
- 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 a 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 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.
- It comes in different colors.
- It is elastic and as such, it adheres well to any surface, as long as it is smooth.
- It 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.
- It can tolerate movement on joints due to its elasticity and will not distort.
- Besides being waterproof, silicone caulking is also heat and cold resistant.
- You cannot paint over silicone due to its ability to repel moisture
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 caulks. 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.
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.
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.
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.
