Best Caulk

Caulk is a sealant that's used to create weather and water tight seals in gaps around your home, like doors and windows or around bathroom fixtures. It's sometimes used like an adhesive as well for things like affixing a ceramic tile backsplash in your kitchen.

The main thing you have to remember when looking to purchase caulk is to keep in mind what you want to use it for and where you want to use it. There are many different kinds of caulks and each are formulated for different uses. For instance, perhaps you need a caulk to use with the plumbing in your bathroom. In that case, you'd want to take a look at our tub & tile caulk list. Or maybe you need a good painter's caulk. In that event, you'd want to check out our best paintable caulk list.

No matter what you need it for, we have a list for you to help you decide what product is best to buy.

Loctite Polyseamseal All Purpose Adhesive Caulk

The Loctite Polyseamseal All Purpose Adhesive Caulk is the top all purpose caulk because it’s designed to be used as both an adhesive and a sealant. Furthermore, it can be bonded to pretty much anything, including metal and concrete (which can be hard to bond). This makes it more valuable. It’s also water based, which is great because that makes it environmentally safe (non-toxic) and can be cleaned up with soap and water. My final favorite part about this caulk is that it is both mold and mildew resistant. This is good if you want a long lasting caulk as it inhibits the growth of mold and mildew.

Liquid Nails All Purpose Adhesive Caulk

Liquid Nails All Purpose Adhesive Caulk

The Liquid Nails All Purpose Adhesive Caulk is a great caulk to buy because like the Loctite caulk, it can also be used as an adhesive. This caulk also makes the final seal mildew resistant, which makes it a long lasting caulk. Another thing I loved about this caulking is that it fully dries in five days. This is pretty fast. In my experience, most caulks take somewhere between seven and 14 days to fully dry, so five is good if you’re on a time constraint.

DAP Alex Plus Acrylic Latex Caulk Plus Silicone

The DAP ALEX PLUS Acrylic Latex Caulk Plus Silicone is on this list because it is flexible. This makes it more durable because it can move with whatever surface you’re working on. This also makes the waterproof seal more efficient. I also like this caulk because it’s paintable, which means you don’t have to worry about it ruining the aesthetic value of what you’re working on. My final favorite thing about this caulk is that the final, dried product doesn’t crack when exposed to seasonal temperature differentials. This makes it a great caulking to use outside of your home.

Red Devil 0816 100% Silicone Sealant

The Red Devil 100% Silicone Sealant (White) is worth considering for purchase because like the Loctite caulk, it can be used as an adhesive with surfaces that can be difficult to bond such as glass, aluminum and plastic. Like the DAP caulk, this caulk doesn’t crack, shrink or peel when exposed to seasonal temperature differentials. This is a long-lasting caulk. Just in case you were still worried about that though, it comes with a 50-year warranty. This makes your purchase a lot easier.

Eco-Bond 10.1 oz. Multi-Purpose Adhesive

The Eco-Bond 10.1 oz. Multi-Purpose Adhesive is the final caulk on this list because for one, it is completely non-toxic. This is great if you have children or pets in your home. As an extension, it produces little to no odor. This is good if you have a job to work on in a small space, such as in your bathroom. It’s also UV resistant, which makes it great to use for outdoor applications. The final best thing about this caulk is that it can be applied and the bond dries underwater. This is good if you need to work on something like a fish tank.

Loctite Polyseamseal Tub & Tile Ultra Sealant

The Loctite Polyseamseal Tub & Tile Ultra Sealant is the top tub and tile caulk because for one, BioGuard, the agent that makes the caulk antimicrobial, helps prevent any stains and odors that may come from bacteria in addition to hindering its growth. This is good if you’re worried about the aesthetic value of what you’re working on. It also comes in three different colors, so you can better suit it to whatever room you’re working on. Furthermore, it’s a very durable caulk thanks to the addition of silicone. My final favorite thing about this caulk is that it can be cleaned up with soap and water, and it’s non-toxic. This is good if you have small children or pets in your home.

DAP Kitchen & Bath 100% Silicone Rubber Sealant

The DAP Kitchen & Bath 100% Silicone Rubber Sealant is another great tub and tile caulk to consider buying because for one, it has silicone. This makes it more durable. It’s also safe for surfaces that will come in contact with food, which makes it great to use on kitchen counters. Like the Loctite caulk, this one is available in more than one color. My final favorite thing about this caulk is that it comes with a 50 year guarantee. This ensures your caulk lasts as long as possible.

General Electric GE286 Kitchen and Bath Silicone II Caulk

The GE Silicone II Kitchen & Bath caulk is one of the best on the market because it has a very fast dry time. This caulk can be used on your bathtub or shower and be ready for bathing use in only three hours. This is very quick as most caulks put your bathtub out of commission for at least a day after applying. This caulk is also great because it’s guaranteed to keep your seals mold and mildew free for five years if cleaned regularly. This is good because it lengthens the time that you don’t have to worry about bacteria growth as much. In addition to that mold free guarantee, it also comes with a lifetime durability guarantee. These combine to make it a long lasting, durable caulk to buy.

Red Devil DuraGuard Kitchen & Bath Siliconized Acrylic Caulk

I have included the Red Devil DuraGuard™ Kitchen & Bath Siliconized Acrylic Caulk on this list because for one, it provides a strong seal that won’t shrink or crack thanks to the silicone. This is great if you want a long lasting caulk. This product can also be painted over once dry. When you combine this with the fact that it comes in several different colors, you can match up the caulk perfectly to the color of whatever you’re working on. This is good if you’re particularly worried about how the finished seal will work. The final reason for including this caulk on this list is that it can be cleaned up with water, which is good because it’s safer.

ECO-BOND Kitchen-Bath-Plumbing (KBT100)

The ECO-BOND Kitchen-Bath-Plumbing (KBT100) wraps this list up because it’s completely, 100-percent non-toxic. It doesn’t give off any odor while it’s curing and no ventilation is required. This makes it perfectly suited for homes with children and pets. It’s also a UV resistant caulk, which means it’s good to use around windows in your bathroom or kitchen, where sunlight exposure would be more common. The final best thing about this caulk is that it can be applied to your tub or shower and be ready to use for bathing in only 30 minutes. This is insanely quick, which is awesome because of reasons I mentioned above.

Loctite Polyseamseal Rain Guard Washout Resistant Exterior Sealant

The Loctite Polyseamseal Rain Guard Washout Resistant Exterior Sealant is the top, completely non-toxic exterior sealant because for one, it is washout resistant. This is good if you’re working in an area prone to rain because an unexpected rain before the sealant is cured won’t rinse it off. It’s also paintable, which is great if you want a caulk that won’t affect the aesthetic value of the exterior of your home. Finally, it’s mildew and mold resistant, which is good because mildew and mold can yellow and stain the caulk with age.

Liquid Nails Window & Door Supercaulk White (LC-130)

The Liquid Nails Window & Door Supercaulk White (LC-130) is a great exterior caulk to consider buying because its seal, which is both air and water tight, doesn’t crack or peel with age and exposure to temperature variations. This is good if you want a seal that will last as long as possible. Furthermore, it cleans up easy with water, which is good if you don’t want to use mineral spirits on the outside of your home. My final favorite thing about this caulk is that it comes in five different common colors used in architectural styles (almond, clear, grey, sandstone and white). This is a lot more colors than most caulks come in and it’s great if you want to perfectly suit your caulk to the outside of your home.

DAP Silicone Plus Premium Window & Door 100% Silicone Rubber Sealant

The DAP Silicone Plus™ Premium Window & Door 100% Silicone Rubber Sealant is an exterior caulk worth buying because like the Liquid Nails caulk, the seal doesn’t shrink, crack or peel with age. Furthermore, this caulk produces low odors, which is good if you’re applying caulk in an area frequented by children or pets. I also like that this product is also mildew and mold resistant. My final favorite thing about this caulk is that it comes with a lifetime guarantee.

DuPont AIRTITE Siliconized Acrylic Caulk

I have included the DuPont™ AIRTITE? Siliconized Acrylic Caulk on this list because it stays flexible even in low temps. This is good if you’re home is located somewhere that frequently sees freezing temps. It’s also paintable, which makes it great if you’re worried about the aesthetic value of your home. This caulk even comes with a 40 year guarantee, which is a great feature to have if you want to buy a durable, long lasting caulk. Finally, I have decided to include this caulk on this list because brand name is important to a lot of people and DuPont has been in business for over 200 years. It evokes a bit of trust in the product.

Red Devil 0876 Window & Door Siliconized Acrylic Clear Caulk

The Red Devil Window & Door Siliconized Acrylic Caulk is the final exterior caulk I have placed on this list because it can be cleaned up easily with water. Like a few other caulks on this list, it’s also paintable. Finally, like other caulks, this product comes with a guarantee of durability. This caulk will stay strong for at least 35 years, which is great for those seeking a long lasting product. Plus, it’s only around $3 a tube, which is insanely cheap for how top quality it is.

Titebond Painter's Plus Caulk

The Titebond Painter's Plus Caulk is the top painter’s caulk on the market because it can be used both inside and outside. This increases the amount of places the product can be used, which gives you more value for your dollar. It can also be painted with one coat without bleeding through the paint. This saves you time and money because it decreases the likelihood you have to use more than one coat on the seal. I also love that the caulk is eliminated of all air. This allows the caulk to extrude in a single smooth line, which makes cut off a lot easier. Again, this saves you time on the job. The final thing that makes this caulk worth a buy is that it’s mildew resistant, which means your caulk won’t discolor with age.

Loctite Polyseamseal Painter's Complete

Loctite Polyseamseal Painter's Complete

The Loctite Polyseamseal Painter’s Complete caulk is one of the best paintable caulk available because it can be painted over in only 20 minutes. This saves you time because you don’t have to wait for the seal to fully dry before applying paint. It also remains flexible with age, so you don’t have to worry about it cracking or breaking. Like the Titebond caulk, it can also be used both inside and outside. My final favorite thing about this product is that it comes with a 50 year durability guarantee. This allows you to have faith in the fact that the caulk is durable and long lasting.

DuPont Painters Caulk with Speed Dry Technology

DuPont™ Painters Caulk with Speed Dry™ Technology is another great paintable caulk worth a buy because it allows spray paints to be applied immediately and brush applied paints to be applied in only 30 minutes. This saves you immense amounts of time, particularly if you use a paint sprayer. Like the Loctite caulk, it also doesn’t crack with age, which is great if you want a strong caulk. This product also is both mold and mildew resistant, which is awesome because it inhibits bacteria growth and prevents discoloration. My final favorite thing about this caulk is that it adheres to glass, a surface not many caulks work well with.

Liquid Nails Painter's Caulk (LC-135)

I have included the Liquid Nails Painter’s Caulk (LC-135) on this list because for one, it is paintable by all kinds of paints in only an hour. It may not be as good as the DuPont or Loctite waits, but it’s still a lot better than most paintable caulks. It’s also flexible, which makes it durable and works both inside and out. The seal that this caulk provides is also mildew resistant, which is nice for reasons I touched on above. My final reason for including this caulk on this list is that like the DuPont caulk, it also adheres well to glass, which can be difficult with most caulks.

DAP ALEX Painters Caulk

The DAP ALEX Painters Caulk is the final paintable caulk mentioned on this list because it’s resistant to both cracking and chalking. This means it’s a durable product that you can trust will last a long time. Like some of the other caulks on this list, this one can be used both indoors and out. This caulk also comes with a 25 year durability guarantee, which makes it so you don’t have to worry so much about getting a long lasting product for your money.

Red Devil Create-A-Color Caulk

The Red Devil Create-A-Color™ Caulk is the top colored caulk available because it can be customized.

Color Rite Exact Color Match Caulk

The Color Rite Caulk is one of the best caulks available for one, because it comes in 450 different colors. This increases the chance that you’ll find a color most like the surface you’re working on. Like the Red Devil caulk, this product is also both mold and mildew resistant. Another cool thing about this product is that the company offers immediate, same day shipping for it. A great choice for professionals. My final favorite thing about it is that it can be used both inside your home and out of it, which is a great feature to have.

Sashco eXact Color Sealant

I have placed the Sashco eXact color™ sealant on this list because it’s customizable with latex paint, stain or pigment.

Furthermore, this caulk can be painted over, which again, is good if you’re working on a paint job. The final best thing about this product is that it comes with a limited lifetime warranty. That makes your purchase a lot easier because you can have more faith your caulk will stay durable.

Wilsonart Color Matched Caulk

The Wilsonart Color Matched Caulk is one of the best colored caulks because it doesn’t contain any ethylene glycol, a mildly toxic chemical found in a lot of different caulks. This makes it safer to use. It also stays flexible with age, which is great if you want a durable, long lasting caulk for your money. Finally, like some of the other caulks on this list, this product is stain, mold and mildew resistant.

Furthermore, since it’s made to use with construction, it’s both non-hazardous and non-flammable. This makes it safer to use because it helps to protect against any potential accidents. Finally, this caulk can also be painted over, which is good for reasons I touched on with the Sashco caulk.
