1. DAP 18128 Alex Plus Acrylic Latex Caulk
If you want a Caulk that can be an efficient solution for all your baseboard needs, then it is hard to beat the DAP 18128 model. Not only can this model survive water and mildew, but it can also seal up all cracks and be painted over. Despite the relatively steep price, this model is worth a look at and steals the top spot for the best caulk for baseboards.
Moisture resistant: The DAP 18128 caulk is composed primarily of acrylic latex, but also includes silicone in it. The silicone is especially helpful since it allows the caulk to remain moisture-resistant. This means that you can apply it to any baseboards, even those in your bathroom!
You can similarly use this caulk itself on almost all surfaces that would require some, making it great for those that want to use caulk for multiple applications. However, it can not withstand constant pressured water, and would thus not be suited for water pipes and the sink.
Mildew resistant and paintable: One of the primary issues that people tend to face with caulk is how bad it can look when applied to any surface. Mildew tends to grow on it, it can grow yellow, and many are not paintable.
You won’t face these issues with the DAP 18128 caulk though. This model is mildew resistant and ensures that your baseboard remains clean. Similarly, it is composed of acrylic latex, which allows you to paint over the caulk if you wanted to do so.
High durability, bad quality control: The DAP 18128 is one of the highest quality variants of caulk that you can buy. One application of this product ensures a 35 year sealing of cracks. With this ridiculously long period of resistance, you will find very few products that can match the durability the DAP offers.
While the quality of the paste itself is great, the quality control seems to be lacking. Many reviews state that the product came with lesser quantity, unsealed, repackaged, or leaked and taped together! With these quality control issues, the caulk might not be a worthy investment.
However, replacements are offered were you to require them, so that partially sorts out the problem.
Expensive but good value: The product is in no way cheap. The package comes as a pack of 3 5.5 oz tubes, which means that you get 16.5 oz of the paste. The price charged for this quantity is marginally higher than what the competition charges for acrylic latex caulk.
However, it is also important to note that this product has added silicone that helps with moisture resistance. Silicone is expensive, and can greatly raise the price of a product. Given that, we believe that the product is a good value, despite the steep price tag that it hosts.
2. Sashco Big Stretch Acrylic Latex Caulking Sealant
The product by Sashco lives up to its name and provides you with a caulk that can stretch and cover large gaps. This earns it a spot among the best caulk for baseboards, given how it can cover up the cracks of any size and do so very efficiently.
High quality: With an almost perfect rating on Amazon, Sashco certainly ensures that you run into no quality issues. The caulk works well, and will quickly be able to close up any and all gaps between your baseboard and the adjoining areas.
The product is not defective, and the quality control seems high. This is particularly helpful to anyone that does not want to go for exchanges. The durable sealant lasts long but is not as long-lasting as others on the list. Nonetheless, you shouldn’t have to replace it for years, which works well enough for most people.
Paintable: The Sascho provides us with an acrylic latex caulk, which means that it can be painted over. This is particularly helpful for those of you that have a coloring scheme to match up with your baseboard.
Many caulk can not be painted over, which means that they might appear as ugly blotches in your house. Luckily, the Sashco offers you easily paintable caulk that you can use anywhere.
Limited applications: While the Sascho model does let you paint with ease, it can not withstand water. This means that it would not be the right caulk for you if you are looking to use the caulk anywhere with a lot of moisture.
For those of you seeking to apply the caulk in their bathrooms, you should consider our top pick instead!
Elastomeric: This caulk is stretchable, and that means that it is perfect for joining areas that might have to stretch. This can include joints. With a stretching capacity of up to 500% of the original size, you never have to worry about moving parts again!
Great value: While the price might seem a little expensive at first, you should factor in the fact that you get 126 ounces of paste for that much. With this volume, you are never running out!
The product gives you almost double the paste per dollar when compared to the DAP model, and that makes it a great value. It’s a great bang for the buck if you aren’t going to be working around water pipes!

- It spans gaps up to 2" wide and stretches up to 500% of original joint...
- Interior and exterior applications including windows, doors, siding,...
3. White Lightning W13000010 Painter’s Acrylic Latex Caulk
If you want a caulk that sticks to the basics, the white lightning will suit you well. It does stick to its name and provide you with lightning fast-drying and is easy to paint over. Other than that, it provides nothing fancy and sticks to the basics to get you the best value.
High quality: With near-perfect ratings, this product does not fall short on quality despite the price-drop that it offers. The caulk has great quality control, and all products seem to work great out of the box.
However, given that it is acrylic latex, it does not last you as long as some other caulk might. Nonetheless, it does give you over 20 years under the hood, and that is more than enough for the needs of most people, especially given the price!
Fast-drying: if you don’t want to sit around watching your baseboards all day to ensure that your cat doesn’t decide to scratch on them, this caulk will save you the hassle. While most caulk takes hours upon hours to dry, this one would be set and ready within an hour of application.
This is particularly helpful if you’re a busy person, and can save you a lot of time!
Paintable: While this white-colored caulk should match most baseboards well, if you decide to paint on it, you’ll find it to be as easy as it gets. The caulk is made for painting, and will not give you any trouble as you run the brush over its lightning-fast finish.
Not water or mildew resistant: Despite the many features that it does offer, this caulk is not water or mildew resistant. This might be fine for people that do not have to deal with higher humidity or plan to use it away from the bathroom, but this caulk would fail you if you try to use it near or on water pipes or the sink.
If you have had problems with mildew, or want to use caulk in your bathroom, you may consider some of the silicone-added or silicone-based products instead!
Excellent value: While the product comes in a 10-ounce pack, it offers unprecedented value. The price per ounce effectively comes down to about a third of what our top pick gives, which means that this product has an even better value than Sashco.
Add the lightning-fast finish and easy paint jobs, and you get a blast for every dollar that you spend.
- This product adds a great value
- Elegant design and smooth finish
- The product is manufactured in United States
4. DAP 18065 Alex Plus Acrylic Latex Caulk
DAP outdoes itself again by providing us with a caulk that we can not ignore. If you were surprised by the value offered by White lightning, then this would definitely not fail at impressing you. Let’s see what sets this caulk apart!
High-quality control: While the previous product of DAP seemed to have many quality control issues, this one manages to remove them. DAP has ensured that every product delivered to you is of the highest quality, and isn’t leaking or pre-used.
The durability is similar to the white lightning product and rests at over 20 years, which should last you long enough. Nonetheless, it isn’t the best that you can get in the market, and we have seen caulk that can far surpass that, including our top pick.
Paintable and fast-drying: While the caulk does not dry as quickly as the white-lightning, it doesn’t take more than a few hours to settle. This means that you should be getting about your caulk application in a couple of hours, and it would save you a lot of time.
The caulk is also easy to paint and will ensure that your baseboard does not seem off. You can easily color up this caulk in whatever fits your need, without breaking a sweat.
Easy cleaning: if you want your caulk to be cleaned easily, then you have the perfect solution in this DAP model. The model offers easy water clean-up, which means that you can simply apply a wet cloth over it to clean up any dust or particles that it may have accumulated.
Not water-resistant: Despite the number of features that this product offers, it is not water-resistant. This means that if you let water on it for extended periods, you will find it breaking down much quicker.
If you plan to use the caulk on baseboards within a bathroom or on other such places, then you should consider the DAP 18128 instead, which has silicone added into it to help with that.
Best value: This product offers the best value in the market right now. Granted that it does not dry as quickly as the White Lightning, and lacks the flexibility of the Sashco, but it costs just a fraction of their price!
The product will cost you nearly half as much as the White Lightning would have, and provides you with 10.1 ounces in that price. This is the best-valued caulk that we found and can be perfect for anyone that plans to use it only for places away from water.
- Indoor/outdoor Alex white painters caulk, 10. 1 oz. - 441230
- This is highly durable

5. GE Ultra Seal Siliconized Acrylic Latex Caulk
If you want a product that can last your bathroom baseboards as well, and would not be affected by the humidity, then the GE Ultra might be the solution. While this product is not as effective as our top pick, it slashes prices enough to make its way into our list of the best caulk for baseboards.
High quality and durability: The product boasts a perfect 5-star rating on Amazon, which is a testimony to the high quality that they offer. Each product will work perfectly, and you will not find the products being ineffective or the packaging broken.
The product also has silicone added to it, which means that the durability is enhanced. The product can easily last you for as many as 30 years, which puts it nearly at par with our top pick!
Versatile applications: The product is water-resistant, and can thus offer you a number of versatile surface applications. You can easily use this caulk on any baseboard in your house.
Other than surfaces that are constantly exposed to water, such as a sink, pipe, or a bathtub, you will find that this caulk can seal up any and everything. It is perfect for your baseboards, and can also work in most other areas.
Paintable, stretchable, and mildew resistant: The features of this product do not end with water resistance. This product can easily be painted as well. While you will need either latex or oil-based paints for application, you can easily paint on this caulk.
The caulk is also stretchable and elastomeric. The flexibility is in no way comparable to the stretch that Sashco offers but still sits at a healthy 200%, which means that you should be fine applying it on joints or moving parts as well.
To top all of that off, this product also resists mildew and mold. That means that you can ensure that your baseboards remain free from defects. The product is also easy to clean with water and soap, so you can keep your baseboard sparkling!
Great value: The product is more expensive than most models that we reviewed. When we factor the per ounce price of the product, it vaguely equals that of Sashco. However, this 10.1 ounces bottle does offer us a great value.
With the number of features that are offered by this product, we believe that you get great value, especially if you plan to use the caulk in very humid areas!
- WATER RESISTANT: Seals and helps protect against water damage...
- MOLD AND MILDEW RESISTANT: Protects against humidity and moisture,...

6. Red Devil 0405 Siliconized Acrylic Caulk
If you want a caulk that will provide you with a better stretch, and mildew and water resistance than the GE ultra, then the Red Devil might be the right fit for you. While it doesn’t do as great as our top pick does with water resistance, it definitely deserves a spot on our list!
High quality and durable: The product is of high quality, and quality control seems to be well in place. Defective products are not delivered, and you should get the right caulk for your needs.
The product is also very durable and should last you a long time. For most siliconized caulk like this one, we see the sealing lasting for over 30 years!
Water-resistant: The product is water-resistant, and that makes it perfect for application at baseboards, especially in areas around your sink or bathroom. It will easily be able to survive in the humidity.
However, it does not resist water, as well as the DAP model, does, and if you apply it on the bathroom tiles or tub, you’ll find that it breaks over time. The product might not even last you a month when applied to those areas!
Long drying periods: No one wants to sit around and wait for the caulk to dry. Unfortunately, with this product, you will have to. It takes hours to dry, and may sometimes even take days depending on the humidity of the area of application.
If you want a quick-drying caulk that you won’t have to look over constantly, you may want to check out the White Lightning’s offer instead.
Flexible and mildew resistant: The product manages to do everything that GE does, but better! The caulk is both flexible and mildew resistant, which makes it perfect for application on joints or baseboards that are susceptible to mildew.
It is also paintable, and available in three colors if you decide to not paint on it. The clean-up for this caulk is also very simplistic, and should not take much of your time.
Expensive: The Red Devil might offer a lot of features, but it does not do so cheap. The price for the 5.5 ounces matches the price of the GE Ultra. However, GE offers you 10.1 ounces of sealant.
The hefty price does give you greater flexibility though, so it might be worth the money if you wish to use it on joints and other similar areas.

7. Red Devil 0777 Elastomeric Acrylic Latex Caulk
To those that seek better value, the Red devil offers their 0777. This caulk provides you with a significantly greater value than the 0405 does, but the value comes at a price. The features in this product are nowhere near as great as that of the Red Devil 0405!
Quality control issues: The product itself isn’t bad, and will work just fine. However, getting the right product can be somewhat difficult. Multiple reviews suggest that the wrong product was delivered to them, or one that had defects.
With these issues in quality control, you might want to consider moving to another product if you seek to get the highest quality. The durability of this product is also not as great as most others, and it should last only about 20 years.
Long curing times: The product takes a long time to dry, which can be very stressful if you have kids or pets around. You should consider shifting to another product if you want your caulk to dry quickly.
Paintable: The product can be easily painted over, which makes it perfect for your baseboards if you plan to cover them in a particular color. To make things easier for you, you are also able to choose between seven different colors when buying the product!
Mold, mildew, and microbes resistance: While the product can not resist water and would not work well anywhere near your bathroom, it does do a good job of removing all forms of fungi and bacteria.
Using this caulk, you can expect your baseboard to remain clean at all times. The anti-microbial feature also ensures that your home remains relatively microbes-free, which is a nice touch.
Good value: The product manages to cut costs and provides you with three times more value than the Red Devil 0405. This means that this product equals the White Lightning caulk when it comes to price, despite lacking the quick-dry features.
That should make this product perfect for the cost-conscious that seek mildew and mold-free caulk that they can paint over.

8. Gorilla White Silicone Sealant Caulk
All of the caulk that we have reviewed previously were unable to withstand direct water for long times. That makes them unsuitable for usage on sinks and other such areas that are constantly in contact with water. This caulk, however, manages to withstand water and thus makes its way into the list of best caulk for baseboards.
High quality: The tube can be hard to use and might not be the easiest to apply, but it definitely has a high quality. The product quality is well controlled, and you won’t find pieces that won’t live up to your expectations. This high quality sets the product apart.
The product is also very durable, and can easily last at least 35 years. This means that you will not have to reapply this caulk on a surface any time in the near future!
Water-resistant: The caulk is truly water-resistant, and will easily handle any amount of water. That means that you can use them on your bathroom baseboards without a second thought. In fact, you can easily use them on your sink or water pipes as well!
That makes this caulk perfect for multi-purpose usage. You can use it on any material that you like!
Mold and mildew resistant: If mold and mildew bother you, then this caulk won’t disappoint. It is made with a formula that resists all forms of mold and mildew, and you can rest assured that they would not be bothering you any time soon.
Can’t be painted on: Being a true silicone sealant, this caulk can not be painted on. This might not be the greatest disadvantage of water pipes, but they can look ugly on your baseboards. The will not mellow, but it remains a translucent white.
Expensive: The pack contains 10 ounces of caulk. The pricing per ounce is almost double that of most of the products that we reviewed, which makes it a little expensive.
However, it is important to realize that the product does base on pure silicone, which is naturally expensive, so the price is ultimately justified.

- Indoor/outdoor; 100% waterproof
9. DAP 18275 DYNAFLEX 230 Elastomeric Sealant Caulk
If you want nothing short of the best, then the DAP 18275 may just satiate your demands. This caulk includes a number of features that set it apart from the competition and is noticeably low on emissions. It does, however, charge a premium price.
High quality and durability: The product can be difficult to squeeze out of the tube at times, but is generally of high quality. The control over the quality is exceptional, and you can expect to have the perfect product delivered to you.
The durability of the product is also commendable, and it should last you at least 35 years, which means that reapplication would not be necessary.
Water-resistant: The silicone mixed into this sealant makes it water-resistant, which means that baseboards in humid areas can be covered with this caulk. However, it won’t withstand constant contact with water.
Elastomeric: The product can easily flex and bend, as well as stretch. This means that you can easily use it on joints or on moving parts, which makes it perfect for people that want to use this caulk on multiple surfaces and areas.
Paintable: This caulk can be painted over, which means that you can easily blend it in with your baseboard. You don’t have to stick with the bland looking caulk. The product also doesn’t emit any odor, and that makes it perfect for you if you wish to maintain a low-profile caulked gap.
Expensive: The offerings of this product sadly don’t come at a reasonable price. This product charges higher than Gorilla, and Gorilla is pure silicone!
We thus believe that you should look for other products if you want a budget-buy. If you want the best stretch and quality though, this product is definitely hard to beat.
- Premium window, door, siding and trim sealant
- Blocks drafts and keeps out moisture and pests
- 100% waterproof and weather-proof
10. DAP 18001 Kwik Seal Caulk
The DAP 18001 somewhat follows suit to the 18275 but isn’t flexible. It does offer you some additional features at a slightly higher price. The reason that this caulk made it into the list of the best caulk for baseboards is because of how easy it is to clean. If you plan to use it in places you won’t be cleaning, we recommend buying something else.
High quality and durability: The product has silicone added to it, which means that it will last a long time. The quality of the product is generally good as well, which adds to the appeal.
The quality control is noticeably high, and not many people have complaints. It does seem to take an unreasonably long time to settle though, which might be concerning.
Water and mildew resistance: The product has added silicone and can thus resist water. This means that it can be perfect for usage in the bathroom baseboards or other such humid areas.
The formula is also resistive to mildew and mold and leaves your baseboard sparkling and clean.
Easy to clean: if the mold resistance isn’t enough for you, then you’d be glad to know that this product is supremely easy to clean. All it takes is a quick wipe with a wet cloth, and you would have cleaned any dust that the caulk accumulated.
Most caulk is much harder to clean. The fact that this caulk also tends to get less mellow is definitely an added bonus. If you still find the yellowing concerning though, you can always paint this caulk. It is paintable.
Expensive: If you want to buy this product purely because of the ease of cleaning that it offers, that’s your choice. Other products provide way better value to you than this one would. To compare, you can get around four times more caulk at the same price if you choose to go for the GE Ultra!
This price difference is one of the reasons that we had to dip this caulk this low, despite the great features that it offers. However, discounts are often offered, so look out for them!

Best Caulk for Baseboards: Buyer's Guide
Now that we have gone through the various caulk that you can buy, you may have already set your eyes on one or some of them. Making choices can still be hard. Fortunately, we’re here to help you make the right choice!
Acrylic latex caulk vs silicone
The most important aspect when buying a caulk comes down to the base material. There are more materials that you may be able to choose from as well, but most household caulks are either acrylic latex, silicone, or a combination of the two.
Acrylic latex caulk can handy for areas that would not be exposed to water. The caulk is usually much cheaper than the other varieties and is supremely easy to paint over. That makes this type of caulk the best for you if you wish to not use it in humid areas and want to paint over it.
If you want to work in humid areas like bathroom baseboards, but do not want to lose out on the paintability, then you’re best going for an acrylic latex caulk with silicone added into it. This caulk can resist mild water contact, and will not immediately melt away.
If you want a caulk that would work on surfaces that are consistently in contact with water, then you are best off going for silicone caulk. These are very durable and can resist water with ease. However, they can not be painted and are typically more expensive.
Ultimately, each type of caulk has some tradeoffs, and it comes down to you on which one you decide to buy. For baseboards, we recommend either the acrylic latex caulk or one that includes a little silicone in it if you have baseboards within your bathroom as well.
However, if you will be using your caulk on your sink and other such areas as well, and do not mind being unable to paint it, then a silicone-based caulk will serve you the best. It is also important to remember that if anyone claims to provide paintable silicone caulk, it’s not pure silicone and has limited effectiveness.
Quality and durability
A caulk is meant to last a long time and seal up holes or gaps for you. That means that any form of compromise on quality is not acceptable, and you should only get the higher quality caulk, even if they charge a little more.
For durability, you should aim for at least 20 years from the acrylic latex caulk and 35 years from silicone caulk. Anything below that is simply not competitive, and you can easily find better caulk in the market.
Odor and color
We have already decided on the paintability of the caulk. The odor of caulk is also something that might be concerning to you. Silicone caulk typically tends to have harsher odors.
However, you can often buy odorless caulk as well, if you find the odor too repulsive to work with.
Curing time is the time that it takes for caulk to fully settle and dry. This can range from a single hour to over 2 days!
If you have pets or kids that might touch the caulk, then you should ideally search for lower curing times. It’s a hassle to sit and watch a caulk to ensure that nobody ends up touching it!
Otherwise, curing times can be a secondary concern since you can simply let the caulk dry on its own without needing to check up on it.
Mold and mildew resistance
If your home has previously displayed trouble with mold and mildew, then you might want to consider getting a caulk that is mold and mildew resistant.
These are typically more expensive, but don’t mellow and ensure that your baseboards do not get attacked by mold and mildew.
Most types of caulk are now elastomeric. This means that they can stretch and bend. While working on baseboards would not require such caulk, you may opt for an elastomeric one if you want to work on moving parts as well.
Some models such as the Sashco are great at stretching and can stretch up to 500%. These can make them perfect for your needs if you need to fill up gaps in moving parts.
If you’re going for silicone caulk, you can typically find great caulk for under 2 dollars per ounce. You can find acrylic latex-based caulk for under a dollar per ounce.
Generally, anything above these prices is simply too expensive when compared to the market, but if you find a product that you really like, you may choose to go above these guidelines.
