There are many different brands on the market, but you should take note of…

1. Resistance against Mold and Mildew

While a seal made by caulking can wear out after some time, this process can be fastened when mold or mildew appears. In other words, it is important to look for a brand that has resistance to these, so you don’t have to worry about the seal after you fix it for a good while.

2. Resistance against Water

This is also a crucial aspect to look for when choosing a caulking gun. If you are going to use it in the bathroom, this feature is a must-have for a sealant.

The water resistance can help you a lot if the seal is meant to block leakage, hole, and even gaps in some rainy area. Moreover, water and damp places are where mold and mildew thrive, so it is a feature you must not skip.

3. Flexibility and Elasticity

If you are intended to use a caulking gun on non-movable places and want to save some money, you can ignore this feature. However, a seal on a door or any kind of moving place must have a certain degree of elasticity, so that the seal does not break easily.

4. Heat and Cold Resistance

Since you are going to use caulk for the bathroom, where hot and cold intersect each other frequently, you should check this feature out. By having this feature, the seal will be much more durable.

Even if you don’t plan to use this in the bathroom, it is still quite convenient when the outdoor temperature change.

5. Capacities

Whether you need to buy a gun or a tube depends on how serious is the place you need to seal. If it is just a small area, a tube will do just fine. However, if the gap is too big or too long, a gun can do a better job and less time-consuming.

6. Drying Speed

A normal and cheap caulk will take a few days or even weeks to dry out. So you should find a fast-dry caulk, the faster the better. You cannot expect to not go to the bathroom or shower for a week.

7. Other small aspects

There are other small features that you can do without. For example, the colour and the price. If you prefer a different color other than white and clear, you can try to find a paintable caulk or some caulk brand with fancy colours. One more thing is the price.

Of course, better caulk is usually more expensive. However, you might not want to spend a fortune just to buy a caulk, as it is intended to fix things.
