Applying waterproofing sealant for the bathtub can be easily labeled as “caulking”. It’s a common misconception in household maintenance to confuse the caulk and sealant.

Sealant and caulk have a lot of things in common. Both are used in to seal gaps and cracks, but what sets the two apart from each other is that sealant, compared to caulk, is more elastic. Caulk, when it dries up, is rigid and abrasive. This makes the sealant more reliable over caulk when used in bathrooms because sealants are made to “adjust” to changing temperatures. Its elasticity makes sealant preferable for bathrooms. Caulk has a tendency to crack or chip after a period of time.

Step 1 - Prepare Your Work Area

Clear away any obstruction that will serve as a hindrance to your work. Make sure that the area is free from dust and water spills. Get your utility knife and remove any old caulk or silicone present in your work area. Use your liquid soap and sponge to thoroughly clean the away dirt.

Step 2 - Prepare Your Sealant

Load the sealant into the dispenser gun and test first to even the level of the sealant. Use a piece of old cardboard or a newspaper to serve as a tester. Applying the sealant can be quite difficult for the first-timer, so it would be best if you practice first before applying to avoid any mess.

Step 3 - Apply the Sealant

Tilt the dispenser gun at a 45 degree angle to let the sealant go down. Remember, this step will help you determine the amount of pressure you put on the dispenser gun. If it’s your first time applying sealant, use a masking tape to serve as a margin in order to avoid any mess while working. If you have sealant on your hands, use a damp sponge or rag to wipe it away. Slowly remove the tape once you are done with your work. Dispose the tape at once. Make sure you have proper ventilation in the room to let the air in and lessen the strong smell of the waterproofing sealant.

Step 4 – Let the Sealant Dry

Follow the directions written at the back of your sealant to know the drying time. It would be safe to let the sealant dry for 24 hrs. Fill your tub 3/4 full with water. This allows the sealant to “adjust” to the weight of the tub whenever it is filled with water.

Step 5 - Clean the Area

After the sealant is dry, clean the area to make sure that there is no dirt.  After drying and cleaning, your bathtub is now waterproof and ready to use.

Put in mind that whenever you make any purchases for the maintenance of your bath, first ask the customer service which products are good for your home.
