Caulking is the process of sealing up the cracks and gaps between two surfaces with a sealant. There are many different types of caulks, but the two main types are sanded and unsanded.
Sanded caulk is more expensive than unsanded, but it lasts longer and looks better. It can also be painted or stained to match your decorating scheme.
Unsanded caulk is less expensive than sanded because it has a shorter life expectancy; however, this type of caulk is less noticeable when applied correctly since its color matches that of most ceilings or walls.
Here we will compare sanded vs. unsanded caulk so you can choose the right one for your needs.
What is Sanded Caulk?

Sanded caulk is a type of caulk made with sand mixed into the sealant. This makes it harder and more durable than unsanded caulk. It also gives it a smoother, finished appearance.
Sanded caulk is recommended for highly visible surfaces such as windows and doors. It is also a good choice for sealing bricks, textured walls, and sections of walls that will be painted or papered.
What is unsanded Caulk?

Unsanded caulk is a type of caulk that is made without sand. This makes it easier to apply and much less noticeable.
Unsanded caulk is not recommended for visible surfaces or outdoor use. Still, it works well for sealing around tubs, showers, sinks, cabinets, corners of walls that meet ceilings or floors, furnishings like bookcases and kitchen counters, countertops in bathrooms, and kitchens.
It is also easy to clean up. It is ideal for use in areas that do not require a lot of durabilities or where you want the caulk to blend into the wall or ceiling color.
Tools for Applying Sanded & Unsanded Caulk

Caulking Gun
A caulking gun is a tool that is used to apply the caulk. It has a barrel-shaped body with a plunger at one end and a nozzle at the other.
The plunger is used to force the caulk from the barrel and the nozzle is used to control the flow of caulk.
There are two types of caulking guns: manual and pneumatic.
Manual caulking guns are powered by your hand, while pneumatic guns are powered by compressed air.
Which Type of Caulking Gun Should You Use?
If you are using sanded caulk, you should use a manual caulking gun because the sand will make it harder to push the caulk through the nozzle.
If you use unsanded caulk, you can use either a manual or pneumatic caulking gun. The type of caulk you choose will determine which gun is most effective for your job.
Nozzle Cutter
A nozzle cutter is a tool that is used to cut the tip of the nozzle off of a caulking gun. This makes it easier to apply the caulk because you don’t have to worry about getting the nozzle close to the surface at a preferred angle.
To use the nozzle cutter, simply place it over the end of the nozzle and press down. This will cut off the end of the nozzle.
Steel Tape Measure
A steel tape measure is a tool that is used to ensure that you apply the proper amount of caulking.
Using steel tape helps to mark off sections and then go back and apply the caulk in those sections. This makes sure that you do not use too much caulking and waste your product.
You can mark sections on a wall using a steel tape measure or a pencil and ruler. To use the steel tape, simply place it on the surface where you want to start applying caulk and press down lightly with your finger.
Then, without moving your finger from the end of the surface, press down on the tape measure with your finger where you want to mark off the next section. Keep repeating this process until you have reached your destination.
Chisel for sanded & unsanded caulk

A chisel is a tool that is used to remove caulk from a surface.
To use the chisel, simply place it over the caulk and press down to use the chisel. This will break the caulk free from the surface. Then, use the chisel to scrape the caulk away.
Putty knife
A putty knife is a tool that is used to apply and spread caulk. It has a thin, flat blade that is made of metal or plastic.
When using a putty knife to apply caulk, it is important to make sure that the blade is clean and dry. This will ensure that the caulk is applied evenly.
Hold it at a 45-degree angle and press down gently to use the putty knife. Then, move the knife in a back-and-forth motion to spread the caulk.
Rags
Rags can be used to clean up sanded or unsanded caulk. You will need to use a wet rag to wipe away the excess caulk for sanded caulk. Make sure to wring out the rag well before using it. You can use a dry or wet rag to wipe away the excess caulk for unsanded caulk.
How to Apply Sanded Caulk?

If you’re using sanded caulk, here are the steps to follow:
1. Cut the nozzle of the caulking tube at a 45-degree angle.
2. Hold the caulking gun at a 90-degree angle to the surface and puncture the seal on the caulking tube.
3. Apply pressure to the gun and slowly move it along the surface, squeezing out a thin bead of caulk.
4. Keep the gun moving at all times; if you stop, the caulk will start to harden.
5. If you need to make corrections, remove the caulk with a damp cloth and start over.
6. Allow the caulk to dry for 24 hours before painting or staining it.
How to Apply Unsanded Caulk?

Sanded caulk is ideal for filling in large gaps or cracks, such as between boards on a deck. To apply unsanded caulk, follow these steps:
1. Cut the tip of the tube at a 45-degree angle.
2. Push the caulking gun’s plunger all the way down and insert the tube of caulk into the barrel.
3. Hold the caulking gun with one hand and use your other hand to pull back on the plunger.
4. Apply pressure to the gun as you slowly release the plunger, allowing the caulk to come out of the tube.
5. Move the gun in a steady motion along the crack or joint you’re filling and allow the caulk to mound slightly.
6. Smooth the caulk with a damp finger or non-abrasive plastic spatula.
7. Wipe away extra caulk and dry before painting or staining wood surfaces.
Sanded vs. Unsanded Caulk: Pros and Cons

When it comes to caulking, there are two main types of caulk – sanded and unsanded. Both have their own set of pros and cons, making it difficult to decide which type is right for your project.

– Does not come with a paintable finish.
When Should You Use Sanded Caulk Instead of Unsanded Caulk and Vice Versa?

Sanded caulk should be used when filling in large gaps or cracks, such as between boards on a deck. Unsanded caulk should be used when caulking areas that are not highly visible, such as the seams between two walls or the cracks around a window frame.
Both types of caulk are ideal for sealing bricks, textured walls, and sections of walls that will be painted or papered. In general, sanded caulk is more recommended due to its professional appearance and long life expectancy. Unsanded caulk is a good choice for less noticeable areas as well as those that are not destined to be painted or stained.
Mistakes When Using Sanded and Unsanded Caulk
People’s most common mistakes when using sanded and unsanded caulk are applying too much or not enough, not letting it dry completely before painting or staining, and not matching the right type of caulk to the project. Keep reading to find out how to avoid these mistakes!
Taking on a caulking project without being aware of the pros and cons of sanded vs. unsanded caulk can lead to costly mistakes, such as having to redo an entire wall or deck.
Only you know which type of caulk would be best for your project, so make sure that you are familiar with the pros and cons of each to ensure that your caulk job looks professional.
Unsanded caulk is usually easier to apply because it doesn’t build up much when appropriately used. On the other hand, sanded caulk can be very difficult to work with if not applied correctly. It’s essential to take your time when caulking and to avoid using too much caulk at one time.
Sanded caulk tends to be more difficult to work with, but it has benefits that unsanded caulk does not, such as the ability to fill larger gaps and cracks. It is often recommended for use on decks because it can withstand moisture, temperature changes, and other outdoor conditions.
Caulking Tips and Tricks

When caulking, always use a caulk that is designed for the material you are caulking. For example, use silicone caulk for silicone surfaces and acrylic caulk for vinyl surfaces.
Make sure the surface is clean and dry before caulking. If the surface is wet, the caulk will not adhere properly and may peel away over time. If you are caulking a large area, cut the tip of the tube at a 45-degree angle to make it easier to apply.
Hold the caulking gun with one hand and use your other hand to apply unsanded caulk to pull back on the plunger. Apply pressure to the gun as you slowly release the plunger, allowing the caulk to enter the tube.
To apply sanded caulk, place a piece of scrap wood or cardboard under the caulking gun so you can control the build-up of the caulk as it exits the tip.
When applying sanded caulk, slightly lift and pull back on the plunger as you squeeze out small domes of caulk. Smooth out the surface with a wet fingertip or a scrap of plastic, and allow it to dry for approximately 24 hours before painting or staining.
How to Identify If a Caulk is Sanded or Unsanded?

To identify if a caulk is sanded or unsanded, look for the following:
– Sanded caulk will have a gritty texture.
– Unsanded caulk will have a smooth texture.
– Sanded caulk is usually white or off-white in color.
– Unsanded caulk is usually clear or light green in color.
– The packaging for sanded caulk will usually state that the product is ‘self-leveling’.
– The packaging for unsanded caulk will usually not include this phrase.
