What is Caulk?
Caulk is a waterproof sealant used to fill in cracks and gaps around sinks, tubs, windows, counters, and more in your home. You can use caulk to seal siding, masonry, and concrete outdoors, depending on the kind you use.
If you’ve never done any home improvement before, using a caulk gun might seem intimidating. It’s possible that you envision spouting sealant everywhere but the gap you’re trying to close. But a caulk gun is quite simple to load and use.
How to Use a Caulk Tool Like Pros?
It can be a little intimidating to use a caulk gun to apply caulks and sealants. And practice is necessary. Still, there are some simple tricks to getting it right. You can use these caulking tips to help you with everything from selecting the best material for your project to developing your shooting abilities. You’ll be putting down clean, consistent beads in no time.
Tip 1: Choose the Right Caulk
Utilizing the proper caulk or sealant for your project is crucial.
- Use a premium sealant with the greatest flexibility and adhesion possible that can withstand the elements to seal exterior siding, window and door perimeters, and trim and siding joints. Paintable, flexible, non-shrinking, and resistant to dust and dirt, DAP Dynaflex 230 Premium Indoor/Outdoor Sealant also maintains its flexibility over time.
- For interior sealing applications such as molding, trim, baseboards, and window and door perimeters, use a sealant that applies easily and has excellent compatibility with paint. DAP Alex Fast Dry Acrylic Latex Caulk Plus Silicone cleans up with water, dries fast and tools easily.
- Look for a sealant that offers strong adhesion and long-lasting mold and mildew protection in areas with high moisture content, such as kitchens and bathrooms. When it becomes soiled, DAP Kwik Seal Ultra Premium Siliconized Kitchen & Bath Sealant is easily removable and replaceable and resists mildew and mold.
Tip 2: Use a Dripless Caulk Gun
When caulking, you’ll want to be able to stop the flow of the caulk instantly, to avoid messy drips. This is best accomplished with a dripless, smooth-rod caulk gun. In comparison to older-style guns, it also requires less hand pressure on the trigger.
Find one with a cutter built in (to trim the nozzle tip) and a seal punch (used to pierce the foil seal that some tubes have at the base of the nozzle). Check the gun’s thrust ratio as well. This refers to the force or mechanical advantage that is applied each time the trigger is pulled.
Your need for force increases with the thickness of the caulk or sealant you’re using. The majority of sealants and caulks should work with a gun with a mechanical advantage of around 10:1 for the majority of home projects.
Tip 3: Prep the Surface
Start by removing as much of the old caulk or sealant as you can by pulling away or prying. Use a flexible putty knife or the caulk remover tool from the DAP Pro Caulk 8-Piece Caulking Tool Kit. Use a flexible putty knife or utility knife to score one edge of any remaining sealant. This breaks its bond.
After softening it with Krud Kutter Caulk Remover and letting it sit for five to twenty minutes, scrape off any remaining sealant with a putty knife or caulk remover tool. After the old caulk has been removed, wipe down the area with a damp rag. Before using fresh sealant, allow it to dry.
BONUS TIP: To prepare areas like showers for caulking, where the caulk line is highly visible, you may want to use painter’s tape to ensure you get straight lines. On each side, place the tape 1/8 inch or so away from the joint. After caulking and tooling, remove the tape immediately.
Tip 4: Cut Hole in Nozzle
Cut the tip at a 45-degree angle, across, or at a size that corresponds to the gap you’re caulking using a utility knife or the caulking gun’s built-in cutter. If you have various sizes of gaps to fill, cut the tip for a small hole and fill the smallest joints. Then, in order to accommodate the wider gaps, cut it larger.
Tip 5: Load and Practice
Push the release lever, draw back the rod, and insert the cartridge into the gun so that it rests as far forward as it will go. Reposition the rod so that it is resting against the cartridge’s base by pushing it back in.
On some newspaper or cardboard, practice caulking. If you’ve cut the tip straight across, you can hold the gun at a 90-degree angle to the gap and pull or push it, depending on your preference.
Pulling the gun is simpler if you’ve cut it at a 45-degree angle. Maintain constant pressure on the trigger. Release the trigger and then squeeze it again if caulk ever stops coming out. The idea is to move the gun steadily while maintaining a constant flow of caulk.
Tip 6: Work from End to End
Start at one end of the gap and move the gun steadily to the other end. To begin and end at logical transition points is the objective.
When you have a long run and can’t finish it in one go, stop somewhere along the way (avoid stopping at eye level). In order to prevent creating a glob, start at the opposite end and caulk to meet where you stopped the first run.
Tip 7: Smooth Immediately
A neat caulk job requires smoothing. Use a caulk smoothing tool within 10 minutes of application; one is included in the DAP Pro Caulk Tool Kit. In addition, you can use a gloved finger or the back of a spoon.
Use long, steady strokes with moderate pressure for the best results. Dip a spoon or gloved finger in mineral spirits before tooling a sealant that is solvent-based. Alternatively, if the sealant is latex, dampen the tool.
Tip 8: Preserve Leftover Caulk
Avoid throwing away any leftover caulk. So that you can use it again in the future, seal it. If the caulk doesn’t come with a cap, use one of these methods:
- Make use of a cap from the DAP Pro Caulk Tool Kit.
- To create a ball the size of a peanut, force enough caulk from the tube. Then, after moistening your finger, form the ball into a cap and place it on the tip.
- Employ an electrical wire nut.
- Insert a nail or screw into the tip.
How to Choose the Right Type of Caulk
- Rubber (butyl) caulk: The filler for asphalt, aluminum gutters, and roof flashing is suitable for outdoor use. Mineral spirits, a cheap, petroleum-based substance that serves as a paint thinner, can be used to remove excess. Reminder: Avoid using rubber caulk indoors as its solvents are highly flammable and toxic.
- Latex caulk (including vinyl latex and acrylic latex, also known as painter’s caulk): Excellent for almost all interior sealing requirements and some exterior applications, like siding and trim. It is simple to use, and cleanup only requires a wet rag. To match the connecting materials, latex caulk is available in many different colors. Painting is another option.
- Silicone caulk: The best choice for gutters made of aluminum, a home’s exterior, sinks, tubs, and showers. It’s also good for use on glass and other nonporous materials. Only water-based silicone can be painted, and cleanup requires use of mineral spirits.
- Polyurethane sealant: Perfect for use on concrete, masonry, vinyl siding, windows, and other surfaces. It can be painted or stained, is more durable than silicone, and doesn’t shrink. However, applying it can be challenging, and cleanup calls for mineral spirits or a solvent.
Final Thoughts on How to Use a Caulk Tool
Caulk guns make it easy to create a waterproof seal around sinks, windows, tubs, and more.
Make sure you are employing the appropriate caulking material for the task, such as silicone caulk for bathrooms.
If you’re unsure, discuss the specifics of your project with a salesperson at the hardware store so you can buy the best sealant for the job.

Is a Caulk Tool Worth It?
The caulking tool, which typically has flat edges, is perfect for applying or removing sealant from surfaces. This tool gives your projects a professional look and makes it convenient to work with caulk.
Can I Use My Finger for Caulking?
Alternatively, you can simply use your finger. Moisten your fingertip in warm soapy water and drag it with light pressure along the length of the bead. Remove the tape before the caulk starts to set if you’re using it to mask the area around the caulk.
What Happens If You Don’t Caulk?
When caulk isn’t doing its job, water can reach the wall itself, and, depending on when and how your home was constructed, moisture can damage any susceptible material behind the tile and/or bathtub.
