Caulking is one of the simplest, fastest ways to seal up cracks in your home. From covering small indentations up to larger gaps, caulk is easy to apply and hardens quickly so the crack is sealed. For most uses, a caulk gun is used to apply the sealant. But is it possible to apply the caulk without a caulking gun?
How to Seal Without a Caulking Gun?
There are various ways to apply caulk without using a caulking gun. Although relatively inexpensive, there are times in which you may not have access to a caulking gun or do not need to invest in a device that may only be used sparingly.
What follows are four methods of applying the seal without using a caulking gun. The method you use will depend on the type of caulk that you are using to fill the crack or gap.
1. Using Silicone Caulk
Silicone tends to be the most popular type of caulk because it resists moisture. This makes it perfect for areas exposed to the elements and places such as the kitchen or bathroom. However, you cannot paint over this type of caulk, so you will need to choose one that best matches the color of the surface.
How to Use Silicone Caulk without a Gun?
While you do not need a caulking gun to apply silicone, it is tougher to do compared to latex. The process is basically the same.
Cut the tip at 45-degree angle and test out the caulk on some scrap material. This will let you know the size and flow of the caulk before applying it to the gap or crack.
When ready, apply the caulk into the area and then wet your finger before running it along the top for the perfect seal.
If you do the job the right way, the silicone will last for many years. However, keep in mind that cleaning up the silicone is considerably more difficult compared to other types of caulk.
2. Latex Caulk
This type of seal is best used indoors and away from areas prone to moisture. But the advantage it has over silicone is that you can paint over this type of caulk.
Because it can be cleaned up with soap and water, latex caulk is generally superior to silicone caulk in terms of applying it without a caulking gun. You should purchase a latex caulk that either matches the color of the surface or a whiter shade if you are going to paint over the area.
How to Apply Latex Caulk?
Once you have obtained the latex caulk, cut the tip at a 45-degree angle. Test the application of the sealant on some scrap material so you can evenly apply the product. Be sure that the tip is at a right angle for the best application.
To prevent the latex caulk from sticking to your fingers, wear a latex glove during the application process. However, to smooth out latex caulk when it has yet to dry, wet your fingers in some water and smooth it out in that manner. You can also use an applicator tool to do the job as well.
If any imperfections develop in the caulk before it dries, you can always add a little more and smooth it into the crack or gap. Latex caulk does normally dry in about an hour. Once it has dried, you can then paint over it.
3. Aerosol Caulk
Aerosol caulk is a suitable alternative to standard caulk. It works in the same basic manner but can be messier compared to caulk that comes from a tube. You spray the sealant into the crack or gap, but there is some prep work you need to do before spraying in the caulk.
Process
- First, clean up the area in and around the gap. Be sure all the dust and dirt are cleared away.
- Now, you can hold the can to create the stream of caulk to fill in the gap.
- Press the trigger and be prepared for a burst of caulk. This happens because of the internal pressure, but you can quickly clean it up and start again.
- Move the flow of caulk across the gap at a steady pace right down the center.
- Once complete, you can use a caulk remover to clear away the excess. Shape the sealant in the gap using a tool or by wetting your thumb and running it across the line.
4. Use a Paint Brush and Painter’s Tape
If you choose either silicone or latex caulk, using a paintbrush and painter’s tape will help make the application process less messy. Painter’s tape is recommended for surfaces that you want to protect. Plus, it can make the clean-up process quick and easy when applied in the right fashion.
How to Use It?
Apply two strips of painter’s tape, one just above and one just below the crack. If the crack is in a corner, apply the tape to both sides of the corner. The gap between the two pieces should be about ¼”. If the gap is larger, then expand the distance between the two strips of painter’s tape.
Next, cut the tip of the tube to match the size of the gap, which should be about one-quarter inch. If the gap is larger, then keep the opening in the tube at the one-quarter inch spacing. Place the tip of the tube in the gap between the strips of the painter’s tape and squeeze while running it along the crack. Any excess will flow onto the painter’s tape.
If you decide to use a brush to apply the caulk instead of your fingers, that will be quicker. However, it will also be quite messy. Be sure that you do not use the brush to apply the caulk past the tape. Otherwise, you will be cleaning the sealant from the walls. This is only recommended for latex caulk as that can be cleaned up with soap and water.
Next, wet your thumb and smooth out the caulk. Do not pass your thumb over the edge of the gap more than once. Look over the results and if satisfied, remove the painter’s tape before the caulk can dry.
