Siding caulk is a sealant designed for fixing wooden and vinyl sidings, but it is generally not recommended for wood siding. It can be applied anywhere needed, but is typically only used for certain areas of siding. To caulk exterior siding, thoroughly clean the area to be caulked, remove any old caulk or debris, and fill any cracks. If working with wood siding, apply primer before caulking, choosing the appropriate caulk, such as silicone or a silicone-latex combination, for exterior windows.
Wood siding should not have siding caulk applied, as this would impede the natural expansion and contraction of the material. Fiber cement siding should not be caulked either. The bottom of siding boards should not be caulked, as it can cause permanent damage. Caulking along the corners and gaps that allow insects to enter is recommended. Paintable caulking should be painted with silicone.
Siding caulk can be used on several different areas of your exterior siding to help prevent water damage and moisture buildup. Apply a coat of primer to the area that will be caulked, working the primer into the gaps as best as possible. Seams should only be caulked as a last resort, and the underneath side should never be caulked. Trim and siding should only be caulked where the trim butts up to the siding, like Hardie Plank or other lap siding. Properly sealing with caulk prevents moisture from getting behind the boards, eliminating the need to let moisture weep out. Air circulation helps dry the water from behind, but the main reason is to allow for expansion and contraction from the seasons.

In the event that the gap is backed with a minimum 4-inch-wide flashing, the application of sealant or joint molding is not required.
What is the best finish for exterior wood siding?
Oil-based stains are a type of wood stain that uses oil as the base for pigments and other ingredients. They penetrate deeper into the wood, providing better protection and bonding with wood fibers. They are ideal for highlighting wood grain on siding, but have higher VOC content and are more difficult to clean. Water-based stains, like water and acrylic, have lower VOC content and are easier to clean with soap and water. However, they don’t penetrate as deeply as oil-based stains, making them less effective in protecting the wood.
Hybrid stains are a combination of oil-based and water-based stains, aiming to combine the best aspects of both types. They are more durable than pure water-based stains but without the high VOC content associated with pure oil-based stains. Overall, these stains offer different options for exterior wood staining.
📹 How to apply exterior caulking properly…
In this “how to” segment, we talk about the proper way to use exterior caulking and get the job done clean and correct.
That is a very neatly shot sealant bead, but if you don’t use the proper size caulk nice to tool it in, it won’t be 100% bonded to the substrate, and be able to pass a pull test. I work in the commercial world, so that has been burned into my habits and it’s how I teach the new guys. Also, your sealant width must be at least twice the depth for a proper cure. So if you have a skinny but deep joint, you must use backer rod foam to fill in the depth to get closer to the 2:1 width/depth ratio.
This is wrong and right. Some caulking says cut the tube end square and some on an angle. Self-tooling caulks require you to cut the tube end square and keep the gun 90 degrees to what you’re caulking. Caulking is not static and one way across the board. I keep a bucket of water with a clean sponge and rag around and do use my finger. Just not in the self-leveling/tooling caulks. READ THE TUBE
Wrong Wrong Wrong on every last recommendation this guy made,Ive been a journeyman turned Master Waterproofer for 32 years & this guy is giving horrible advice, #1 Thermoplastic caulk sucks & is NEVER architect speced in commercial & industrial waterproofing,any caulking or waterproofing agent that can be just pulled off in 3 days is junk,if it’s adhesion is so low you can pull entire 3 day old caulk runs off just imagine how much water that junk will allow in your building after a season change where the caulk experiences Thermal Shock, #2 The absolute best type of caulking and the type speced by a solid 90% of architects is ” Polyurethane ” based caulk,it sticks like 2 pieces of metal after welding,won’t shrink and outlasts every other type of caulking by decades,#3 where he recommends not tooling in your caulk,caulking not rubbed or tooled I is caulking that’s gonna fail quickly,only a moron licks their finger when a $2.99 7 in 1 tool makes an excellent caulk spreader,even a plastic disposable spoon from McDonald’s works great for rubbing in fresh caulking .
you cut the angle of the tip depending on how deep or shallow you want the application. sealing a shower enclosure with clear silicone, as one example, is different than the material used and size of cracks and crevices at the structures exterior. instructions should read: Cut The Tip To Fit the Desired Application
Hello Friend! I live in Russia and do this business on a professional basis, I polish wooden houses, paint them as an artist and make a canapatka and sealing))) or exterior caulking etc.I want to move to another shit I am looking for a political shelter? I can find myself and how much I can earn !! Thank you very much for your answer!!!
I stopped caring when I saw how he teaches to do window wraps.. and this is a warranty pitch. Any time they bring in the chemical make up they are trying to blame you for their crappy product. Your not allowed to touch the caulk otherwise it wrecks it? 😂😢 sounds like a way out of any and all responsibilities of a manufacturer. Then they will say you didn’t tool it properly when it leaks aswell. I’ve dealt with product warranty issues before and they go back and forth, blaming you one way or another.😅 take everything with a giant cup of 🧂 salt.
I found over the years that there are many variables in applying caulking. The type of gun that is used. Air and tube temperature, the persons ergonomic vector, hand (squeeze pressure). The composition of the material (silicone, latex, or urethane). And the angle of cut on the tip. For me personally, I use about a ten to twenty degree cut. Where to cut on the tube with respect to the diameter application is a judgement call for me on the size of the gap. I also cut on the down slope, as not to leave a plastic “mini-flap” that may act as a squeegee and leave a mark or remove caulking causing an unsightly groove. The angle of the gun in application is paramount. As previously stated: this is what works for me. Other carpenters I know apply differently and have other considerations…..
Good article, but I prefer the Dripless ETS 3000 caulk guns for most common caulking and sealing applications, it’s light weight, built in nozzle cutter and poker, plus you can turn drip or dripless feature on or off and rotaing barrel. I know you have the Tajima High Trust version which would be a second choice for me due to how heavy it is but has plenty of features also. But I do alot of caulking and prefer the light weight of the Dripless ETS series caulk guns.
The splash screens and rock music are a distraction. Just show us how to do caulking, without fancying yourself as a Hollywood actor in a movie. Also, a whole lot was not covered. But that is forgivable because no 5-minute article will cover everything, unless it supplements talk with PowerPoint screens.
I wish there was a way that one could remove all of the absolutely horribly wrong ways to apply caulking and silicone, and replace them with this one. I can’t stand when people do something so simple in an absolutely wrong way, like cutting the tip at a 45, and then holding the gun at an angle, and even worse, applying too much product in the first place and then using either a finger, sponge or spatula to remove the excess, and create all sorts of lines and crevices for build up. Good Job, Sir.
push the gun to fill the gap, seal it, and form a strong insulative bond. pull the gun to leave a thick sightly bead that can peel off. if a clean up is required, ie smooth out the bead, I use a small spray bottle of water and dish soap. mist finger and bead, less is more, work with confidence. if new to this, practice on scrap 1st.
