12 best exterior caulks

Exterior caulks are essential products used in construction and maintenance to seal gaps and joints in exterior surfaces and protect them from moisture, air infiltration, and other environmental elements. These caulks are specifically designed to withstand the harsh outdoor conditions and provide a durable, long-lasting seal. Here is what you need to know about exterior caulks:

Silicone Caulk: Silicone-based exterior caulk is a popular choice for outdoor applications due to its excellent durability and resistance to moisture, UV rays, and temperature fluctuations. It remains flexible over time, which prevents cracking and ensures a watertight seal. Silicone caulk is commonly used around windows, doors, and other exterior openings.
Caulk Types: While silicone caulk is a common choice, there are other types of exterior caulks available, including acrylic latex, polyurethane, and butyl rubber. The choice of caulk depends on the specific project requirements, such as the substrate material, expected movement, and environmental exposure.
Adhesives, Sealants, Lubricants: Exterior caulks fall under the broader category of adhesives, sealants, and lubricants used in various industrial and construction applications. They serve to bond, seal, or lubricate different materials, and in the case of exterior caulks, they serve as a weatherproof barrier.
Applications: Exterior caulks are used for a wide range of applications, including:
- Window and Door Sealing: Caulking around windows and doors prevents drafts, water infiltration, and energy loss.
- Siding Joints: Caulking gaps in siding helps maintain the structural integrity of a building and keeps out moisture.
- Roof Flashing: Caulk is used to seal gaps around roof penetrations like chimneys, vents, and skylights.
- Concrete Joints: Exterior caulk is applied to joints in concrete structures to prevent water damage and erosion.
- Expansion Joints: In large concrete slabs or pavements, caulk is used in expansion joints to allow for movement while maintaining a watertight seal.
Industrial and Scientific Use: Exterior caulks have various industrial applications, including sealing joints in transportation infrastructure like bridges and highways, protecting against corrosion in marine environments, and sealing joints in commercial and industrial buildings.
UV Resistance: UV resistance is a critical feature of exterior caulks as they are exposed to sunlight. UV-resistant caulks maintain their integrity and prevent cracking or fading when exposed to the sun's UV rays.
Paintable Caulks: Some exterior caulks are designed to be paintable, allowing them to blend seamlessly with the surrounding surfaces. This feature is particularly useful for achieving a clean and finished appearance.

In conclusion, exterior caulks, including silicone caulk and other types, play a crucial role in maintaining the integrity and weatherproofing of buildings and structures.They are versatile products used in various outdoor applications, protecting against moisture infiltration, air leakage, and environmental factors, ultimately contributing to the longevity and durability of construction projects.

User questions & answers

Question:	My contractor used this at wall/floor joint and toilet/floor joint. It's very sticky and attracting dust. Was this an appropriate use of the product
Answer:	I used this to caulk around tub and wall several months ago and it has held up so far, so I would have no problem with dust. After reading the specs, I would have not used it on floor. I am not a contractor, just a 78 year old fossil. There are a tons of different caulk applications out there.
Question:	I'd like to know if the brown is light, medium or dark, if somebody can describe it? I wonder if the dark bronze is darker
Answer:	It is a reddish brown
Question:	can this be used over 100% while silicone caulk that was recently put down? I want to cover up in this almond color so I don't have to paint
Answer:	I would still paint it because dirt will stick too caulk and make it look terrible pretty quickly
Question:	Is this good to use in the shower
Answer:	Just because a caulk is waterproof, doesn't mean its good for shower areas. If you go the DAP website you can see that they have caulks for bath areas and caulks for exterior siding. Dynaflex is soft and flexible to seal joints in moving substrates such as siding. Siding expands and contracts with temperature and moisture content. Dynaflex is designed to keep up with that movement, but to do that in a latex formula, means that it is inherently soft and prone to damage. Frequent scrubbing such as in a bathroom environment would quickly destroy any adhesion. It might be fine (though not ideal) for caulking the top of a counter backsplash or where the tile meets drywall, but its not suitable for shower use where you would expect a waterproof joint. You won't see any fish tanks assembled with Dynaflex.

User questions & answers

Question:	when used outside, how many years will this last? only answer if you really know this
Answer:	Thank you for your question. GE Max Shield line of paintable Acrylic sealants are guaranteed to last for as long as you own your home when applied properly. Please consider that it is common for most homes in America to require painting every 7-10 years depending on climate. Most reseal their homes after they paint. Also note products will have different performance characteristics in different environments and acrylic product that has been painted over could last for decades in a mild climate.
Question:	how many catridges for a small one person shower
Answer:	Thank you for your question. One 10.1 ounce tube is enough to caulk two bathtubs and one sink, or three standard doors and four windows.
Question:	I'm confused. The product description says it fills 3-inch gaps, yet the instructions say you need a backer rod for gaps over 1/2-inch. Which is it
Answer:	It's both. It can fill up to 3 inches but anything over 1/2 inch should/needs to have a backer rod to help stabilize it.
Question:	Can this product be used to caulk a tile shower
Answer:	Thank you for your question. Yes, GE Max Shield All Weather can be used in your shower.

Question:	Is it wateroroof
Answer:	I used it to seal my ice shack roof. It was a bit chilly when I applied it. Let's just say when the snow and ice started melting off the roof, it was raining inside my shack. I think it would have been ok if I had applied it when the temp was right.
Question:	Can I use this to fill gaps or imperfections on exterior fascia board before painting
Answer:	You should be able too, this is for exterior or interior use. But you probably want to use an exterior wood fill if the fascia board is wood so you can sand and then paint.

User questions & answers

Question:	Would it be good for rv
Answer:	Depends on what and where. This stuff is great I would say more than likely yes
Question:	If I seal drywall butt joints, can I mud over it once it's dry
Answer:	Yes. Later, if the joint stretches or flexes, the caulk will move with it and the drywall joint will crack.
Question:	does it last 25 or 40 years outdoors? does anyone know
Answer:	I would expect this to last that long, i have several properties where this has been installed for years, needed to remove it for renovation work. It was nearly impossible to get the caulked seams apart. I rate this as some of the best caulk sold. As long as you prep you application area correctly I would expect this to outlast the trim it was applied to.
Question:	Can it be use for a butt seal for fiber cement lap siding
Answer:	Yes should work

Question:	Does this adhere concrete to concrete? I’d like to secure top basin of birdbath to the pedestal so it doesn’t fall over
Answer:	yes this will stick concrete to concrete concrete to Wood concrete to
Question:	Will it glue polyethylene foam to painted wood and to stuccoed drywall
Answer:	As long as the gluing surfaces are dry / clean / even as possible then yes. If a surface is questionable you can "brush" it to increase the adhesive ability since it is being covered.
Question:	Is this clear
Answer:	No, not clear. Sort of grayish or off- white.
Question:	Will this adhere to outdoor stucco walls for hanging hooks and decor
Answer:	I can't say that it will only because I have not tried it for that purpose. However, I used it to attach some large rocks inside a terra cotta bowl and the attached surface is underwater at most times. It has held for over a year in that application.

User questions & answers

Question:	Does this caulk dry shiny or matte
Answer:	When you say shiny I assume you mean patent leather like shiny??? If so, the answer is definitely not!!!! It's a matte black when fully cured.
Question:	Is this caulking paintable
Answer:	It claims to be paintable
Question:	can this be used on my aquarium
Answer:	My guess is no. There is caulking made just for aquariums but it is more expensive. http://www.amazon.com/All-Glass-Aquarium-AAG65010-10-3-Ounce/dp/B0002ASD34/ref=sr_1_1?ie=UTF8&qid=1410170477&sr=8-1&keywords=aquarium+caulk
Question:	do you need caulking gun to use this tube? Can it be used on its own
Answer:	Yes, you will need a medium duty caulking gun. There are products (that don't require a caulking gun) that come in squeezable tubes that are okay for small jobs and/or hard to reach locations. However, it is difficult to lay a professional looking bead of caulk with these tubes and comparatively they are very expensive. If you own a home, especially an older one, you will need to do a lot of caulking and a caulking gun is a wise and inexpensive investment. You should purchase a decent one with a rotating metal wire at the end of the gun (where the nozzle of the caulk tube goes) that is used to pierce foil seals in the nozzles of most painter's (acrylic non-silicone) caulks, and will help to break through any hardened residue in an old tube of caulk if you want to use it after it has been sitting around for awhile.

User questions & answers

Question:	Can this work on shower tile
Answer:	You can use silicone on tile, but it is better to use ceramic tile adhesive to secure the tile to the wall. If you are doing caulking in the shower use tub and shower silicone caulking.
Question:	Does it dry "crystal clear" or does it have a "milky" appearance when it sets? I want to use this for a shower door and I want a truely "clear" caulk
Answer:	As "crystal clear" as any silicone glazing/sealant I've ever used. I used it to seal clear corrugated acrylic roof panels.
Question:	Hi, I would like to glue glass dishes to an old window. Will this product keep the dishes when the window is hanging? Thanks
Answer:	It likely will, provided you add sufficient amount and tape the dish to the window til the caulk complete cures. The other consideration is that the caulk is not clear as glass when it cures, it is a bit cloudy.
Question:	Will this work gluing Styrofoam ceiling tiles to metal ceiling thank you
Answer:	Not permanently. Silicone has very little grip on styrofoam. Look for a specialized styrofoam cement for this job.
Question:	If this caulk is used out in the weather and it is colored will the color (cedar) hold up or does it turn a whitesh color over time
Answer:	I have used this on the knots that where missing on my cedar siding and its been just over a year now and the color is the same.
Question:	Will this smooth into grooves using a dampened finger or silicone caulking tool
Answer:	Yes, it smooths just as well as any other type of caulk I have used. The silicone caulking tool works best.
Question:	Does this work well to re seal existing windows
Answer:	Yes it does an excellent job of resealing
Question:	Will this smooth into grooves using a dampened finger or silicone caulking tool
Answer:	I would liken it to silicone caulk. It is more sticky than regular caulk, but I did use a wet finger. Don't know how a caulking tool would work on it.

Question:	How many linear feet with this cover with an 1/8 inch bead
Answer:	Hello, A 10oz. cartridge of Gorilla White 100% Silicone Sealant will cover 52 linear feet using a 3/16 inch bead. This is approximately enough to caulk two bathtubs and one sink, or three standard doors and four windows.

Thank you, The Gorilla Glue Company
Question:	If used in the shower will it get moldy from the constant water
Answer:	Hello, Gorilla 100% Silicone Sealant contains fungicide and is mold and mildew resistant. Silicones are inherently resistant to microbial growth because they are inorganic. But, because they are frequently used in high humidity environments with the potential to collect dirt, soap, and other deposits commonly found in bathroom spaces, mold and mildew can grow on the surface of the sealant and consume these deposits as food sources. The fungicide leeches to the surface of the sealant to provide continuous (though not unlimited) control and resistance to growth. If we can be of further assistance, please contact our Consumer Affairs team at 800-966-3458 or through our website at www.gorillatough.com/contact and reference case #243740.

User questions & answers

Question:	Can this product be used for better soundproofing windows
Answer:	Thank you for your question. GE Silicone 2 can be used for sealing cracks and holes but it is not certified for soundproofing. If you would like discuss this further, please contact customer service at 1-866-275-4372.
Question:	Is this safe to use on PCB
Answer:	The product will cure to form a contiguous skin/surface. The clear caulk will also adhere to many well cleaned surfaces one would encounter in many construction and home improvement situations. My personal opinion is that I would not expect this silicone-based caulking to encase any hazardous solvents such as PolyChlorinated Biphenyls. PolyChlorinated Biphenyls are very difficult to encase or block as they easily penetrate nearly all organic "coatings" (such as paint) which is why PolyChlorinated Biphenyls are used.for solvents in the first place. The letters "P C B" have numerous meanings to chemists, chemical engineers, and electrical engineers. For example, you may be referring to "PRINTED CIRCUIT BOARDs."
Question:	Can this be used on aftermarket headlights to create a better seal and avoid fog/water collection
Answer:	Yes
Question:	How is this different from the red version labeled for kitchen
Answer:	Thank you for your question. GE Silicone 2+ Window & Door and Kitchen & Bath are similar products that can be used indoors and out. Both GE Silicone 2+ Kitchen & Bath (red label) and Window & Door (blue label) have a lifetime guarantee not to crack, shrink, breakdown or yellow.
