To choose bathtub sealant for your home, there are a few things you should consider. You should consider both the surface you are caulking as well as the characteristics of the adhesive.

The following guide can help provide you with the knowledge needed to choose the best caulk sealant for your home.

Materials to Seal

Before you decide which sealant to purchase, it is important that you consider the types of materials your bathroom is made of. The best caulk sealants are designed for different materials; therefore, they come in different variations.

If possible, start by checking your tub to see what material it is made of. This should give you an idea about the types of sealants you need to purchase.

Type of Adhesive

Different adhesives are designed for different surfaces. No matter what type of shower caulking gun you own, there is almost always multiple tubes that come with different sealants.

If the adhesive is not the right material for your surface, it will give you poor results and could even be unusable on some surfaces.

Mold and Mildew Prevention

Temperature Resistance

In some cases, if the adhesive has not been designed for high temperatures, it can crumble or even become unusable.

Seasonal Weather Resistance

People living in humid areas have a higher risk of developing mold and mildew. To prevent this, you will need to purchase a sealant with added resistance to humidity.

Not only should the caulking gun sealant have a high moisture resistance level, but the adhesive should also be applied in a specific way.

Colors

Although it may seem trivial, certain color additives can improve the look of your sealant. Since many sealants are designed to be used in bathrooms, you should look for a caulking gun that is available in colors such as white or gray.
