What is a caulk gun?
A caulk gun or adhesive gun is a simple tool that people use to apply sealants and adhesives to seal cracks and gaps between materials. People use this tool to seal gaps around the home where waterproofing is needed.
Step-by-step process for caulking
Before you start a caulking job, make sure you gather some basic equipment to help you complete the work without interruptions.
Depending on what type of job you’re doing, you will need these items:
- A caulk gun
- Caulking cartridge
- Caulk softener
- Utility or putty knife
- Needle-nose pliers
- Smoothing tool
- Painter’s tape
- Rubbing alcohol
- Mineral spirits (depending on the type of caulk you are using)
- General household cleaner
- Cloth
- Old pieces of wood, cardboard, or tile
- Silicone squeeze tubes or ready-to-use strips for the tightest places
Remove old sealant
Use the putty knife to remove old, existing caulk material. If necessary, use the caulk softener on old stubborn sealants. If the area has strips, the needle nose pliers will work best to remove them.
Clean the area
Dab rubbing alcohol onto a cloth, clean debris from the area, and wait for it to dry. This should be quick, as the alcohol evaporates almost immediately. Make sure the area is cleaned well before applying any sealant, as it won’t stick properly if not.
Painter’s tape marking
You can use this along the horizontal surface to make clean-up easier after applying the selected caulk material. Simply apply the tape along the surface edges for a neat sealing application.
Load the gun
Cut the tip of the caulk cartridge with the knife, make a hole in the foil with the knife, or use any tool provided to make a hole. This will allow the free flow of the contents. Insert the caulk canister into the gun with the open tip facing downwards. Push it in securely and press the button to release the caulk to check that it flows smoothly.
Practice run
Use a steady pressure on the trigger of the joint filler to lay a caulk bead (line of sealant) in a straight line on a piece of old cardboard, tile, or wood. Try to do this at a steady pace and pressure to produce a neat, even line of sealant for your DIY project. Practice this activity until you’re confident that you will be able to apply the caulk properly.
Application
Hold the caulk gun at an angle of 45 degrees with the tip at the starting point of the job. As you move at a steady pace, ensure you are using enough pressure to release a sufficient amount of sealant to fill the gap in a neat, straight line.
Control is important because the sealant cures or dries rapidly. Fill the gap immediately when you notice there isn’t enough to seal the space before it forms a skin. If you notice a drip, simply use the stop function on the caulk gun to halt its flow.
Smooth the caulk
Use a tool with a flat surface or dampen your finger to even out the caulk, inserting it deeper into the crack. Complete this tooling process for a clean job before the sealant starts to dry and develops a tacky skin. If you work too slowly, the sealant can lose its bonding capacity, and you may have to start over.
Remove the superfluous caulk
If you used painter’s tape to protect the area, remove this now. If not, you could use solvent or water to clean up the excess, depending on the type of caulk that you used. Sealants can dry in half an hour or take several days to cure completely.
Storing unused caulk
Take the caulk canister out of the gun and secure the cap. You can store it for about half a year like this, and it will remain usable.
Types of caulk and guns
As a DIY beginner, you can choose from three main styles of caulk guns. These include a manual non-drip caulk gun, which is best for beginners or anyone who seldom uses this tool. Professionals with loads of experience mostly use electric caulk guns with chargers or pneumatic caulk guns.
There are four main types of caulk described below:
Silicone caulks are ideal indoors and are often used in bathrooms, kitchens, windows, and aluminum guttering. This sealant is suitable for gaps in non-porous materials. Ensure that you’re using a water-based silicone if you want to paint it afterward, and use mineral spirits when cleaning excess applications.
Rubber or butyl caulk must not be used indoors as it is flammable and toxic. However, it is ideal for filling gaps in roof flashings, aluminum gutters, or asphalt. Use mineral spirits to wipe off excess rubber.
Painters, latex, vinyl, or acrylic caulk are ideal for sidings, trim, or indoor seals. Pick your color to match the surrounding surfaces or paint the area once the sealant has dried. These products are water-soluble, so you only need a wet cloth to clean up after completing the job.
Polyurethane sealants work well on masonry, concrete, windows, and vinyl sidings. You can paint or stain this product, which is stronger than silicone and doesn’t easily shrink. Although it is more challenging to apply than the others, it is worth the effort if you have the experience. You will also need to use a solvent or mineral spirits to clean up any mess you make when applying this product.
