How to Apply Caulk Without a Caulk Gun: A Few Options
Here are several ways you can apply caulk without the use of a gun, saving you money in the process:
1. Use Your Hands/Fingers
The most common way for homeowners to apply caulk is with their fingers. Simply coat your finger with the caulk from your caulk tube and apply it to any cracks or gaps that need filling.
When using this method, you should wear gloves so that your hands don’t get dirty or sticky while applying the sealant. And make sure to wash your hands when you’re done.
2. Use a Putty Knife
Another common way to apply caulk is by using a putty knife. Dip the dull side of the blade into the caulking tube and get a nice amount of sealant on it. Then, use the blade to apply the caulk onto cracks or gaps, smoothing it out with fingers if necessary.

3. Use a Paintbrush
An old-school method for applying caulk is with a paintbrush. Simply pour some caulking into a container that has a narrow opening and dips your paintbrush into it.
To apply, just wipe some on any crack or gap you need filling in, being careful not to overdo it so you don’t have excess caulk leaking out. While this method works, it may be messy compared to the others, so use it with caution.
4. Spoon
You might be surprised to find a spoon on this list, but it can work. Simply take a metal spoon and scoop a small amount of caulk onto the bowl of the spoon. Then, use the backside of the handle to apply it along cracks or gaps.
5. Try Using an Old Credit Card
It’s always good to have some spare cards in your wallet. If you do, an old credit card can come in handy when applying caulk. Just put a bit of caulk onto the backside of the card and use it to apply the sealant wherever needed.
You may need to wipe any excess off or let it dry before using the card again, but this method works well for smaller jobs.

6. Butter knife
If you need to patch up a small area, an old butter knife or a utility knife can come in handy. Just scoop some caulk onto the dull side of the blade and apply it along cracks and gaps in your home.
This method is fast and easy but may not be suitable for larger projects as it can take a while to use one butter knife for this purpose.
7. Use a straw
You might not think a straw has anything to do with caulking, but it actually does. All you have to do is cut the straw so that there’s only about an inch of plastic still attached. Then get some caulk on the exposed part and use it to apply the sealant wherever needed.
This method is fast and easy but may get messy if too much gets onto the straw while you’re working with the caulk. If this happens, simply wipe off what you can before placing back in your toolbox or nearby drawer for future use.
8. Plastic Scraper
You may be surprised to find a plastic scraper on this list, but it can work very well. This is a slightly more advanced method that requires you to cut the blade off of an old scraper. After doing so, apply some caulk onto the dull side and use it to fill in cracks or gaps along your walls.
This method works especially well if you have any holes or imperfections in your walls from previous home mishaps. Your patch job will blend right into the rest of your wall for a seamless finish!
9. Use an Old Toothbrush
One of the easiest ways to apply caulk without a caulk gun is by using an old toothbrush. A toothbrush gives you the ability to get into small cracks and crevices, as well as give you precise control of where the caulk will go.
You’ll need some tape for this method. First, place pieces of tape along the crack or crevice where you plan to apply the caulk. Then, use an old toothbrush or a caulking application tool to apply the caulk onto the crack.
The drawback of this method is that it can be time-consuming if you’re working with large areas.
No matter what method you use, just remember that applying caulk without a caulking gun is easy and straightforward. As long as you know how to apply it into cracks and gaps, you’ll be able to do so without issue!
And once you try out these methods for yourself, you just might find that they’re your new favorite hand tools for future home projects. Eventually, you may even stick with one.
Types of Caulk You Can Use Without a Gun

Latex Caulk
Latex caulk is a basic type of sealant that comes packaged in a cartridge. They come in a variety of colors and finishes, so you can find one to match your home as well as the project you’re working on.
Silicone Caulk
Silicone caulk is another option that’s meant to last for years without cracking or peeling. This type has the benefit of being able to withstand extreme temperatures from extreme heat to cold weather conditions.
Oil-based Caulk
Oil-based caulks are made with petroleum and usually work best on exterior surfaces like doors and windows because they can withstand changes in temperature and moisture levels outside.
They’re also resistant to mold, which makes them a good choice for basements and other areas that can be at risk of moisture or water damage.
Water Repellant Caulk
Water repellant caulk is meant to prevent leaks by creating a protective barrier against water penetration. These sealants are recommended for use near pools, patios, and any other area where water spills could become an issue later on.
Additional Tips
If you’ve used too much caulk or it’s messy, there are a few things you can do to get the job done right.
It’s important to note that if you’re applying the caulk in a wet area, such as around a sink or bathtub, you should wait until the area is completely dry before applying your caulking. This will ensure it sticks properly and doesn’t flake off after drying.
If your caulk has dried up, simply apply a bit of water along with some soap and work it into the dried edges.
If this doesn’t work, try using mineral spirits instead of water since these tend to be more effective when it comes to breaking down stubborn materials. You also might find that simply wiping the caulk with a bit of mineral oil can work just as well.
FAQ
What Type of Caulk Should Be Used Around Bathtubs?
It’s always best to use water-resistant caulks around bathtubs and shower stalls. Water-resistant caulk is less likely to harden or crack, which means that it can last for a long time and it can continue to do its job.
What Happens If Caulk Gets Wet Before It Cures?
If caulk gets wet before it has time to completely dry, it may not be able to do its job correctly. Therefore, you’ll want to make sure that the area is free of moisture until the caulk has dried up.
What Caulk to Use for Baseboards?
When you’re looking for caulk or sealant to use along the baseboards, it’s best to stick with something like silicone sealant. Silicone caulks or sealants can be used in high and low temperatures as well as climates that are prone to moisture problems.
You should also choose a clear option, which will allow it to blend into any color scheme you might have going on in your home without causing any issues when it comes time for cleaning.
If the edges of your baseboards look especially worn out, try using oil-based stains or paints before applying new caulk or sealants. This will help to freshen up the final look and give them a sleek finish.
What Removes Silicone Caulk Residue?
Cleaning silicone caulk can be a challenge because it tends to stick around for quite some time. There are several different household cleaners you can use to get rid of the caulk once it’s dried, but one of the most effective may be mineral spirits.
Mineral spirits are available in home improvement stores and they’re highly flammable so you’ll have to be careful when using them around open flames. When it comes to cleaning up messy caulks, mineral spirits tend to work best because they break down even the toughest materials, including silicone caulk.
Additionally, many homeowners also suggest adding dish soap or laundry detergent into the mix since these will help loosen up all the debris that’s stuck onto your surfaces.
