How to caulk bathtub – Detailed instruction
Step 1: Remove the old current caulk
Before applying a new layer of caulk, you need to remove the old one as it can’t be used anymore. To do this job more quickly, you should equip yourself with scraping tools like a razor scraper. Also, ensure to use a plastic blade so that it won’t leave scratches and damages on the surface of your bathtub.
If you have just bought a new bathtub, you don’t need to do this step as there is no caulk on a new tub.
To remove the caulk evenly, put the blade against the surface of the tub, move the tool back-and-forth to scrap all the caulk. Do this work from the corner to the length of the tub and make sure you have removed all the old caulk.

Step 2: Clean the bathtub and prepare for a new caulk
When you finish scraping, clean up the pieces of old caulk by a vacuum or a brush. Then, rinse the clean water on the surface of your tub to wipe out all leftover and hidden caulk. Now, are you ready for a brand new caulk?
Take it easy guys because we are just halfway there. A scraper cannot totally remove the caulk, so you must use two more tools to clean the old caulk evenly.
First, we must use denatured alcohol, which is very useful for removing the caulk and making the tub cleaner, brighter. You can apply the liquid directly on the bathtub or pour a bit into a rag, then wipe down the area which used to have the caulk. This is an excellent way to get a bright surface and prepare for new caulk.
Next, you must bleach the bathtub to prevent molding or mildew, while it also helps make the tub brighter. Mix a bucket of 80ml bleach liquid and 3.8l water, stir well and place it next to the tub for easy applying. Make sure you are well-equipped with a mask, gloves, and a brush for safety.
Use that brush to scrub the tub with water and especially work in the areas of old caulk. Keep the tub dry for 24 hours before applying the new caulk.
Step 3: Choose a suitable caulk for your bathtub
Not all caulk is suitable for your bathtub as it depends on the material of yours. There is a variety of caulk in the store that you should be well-aware of the one you need to use. There are two common kinds: for kitchen/for the bathroom. Bathtub caulk has acrylic latex or silicone form, but you need to know your tub’s material as well.
If you are using a ceramic bathtub, you should go for acrylic latex caulk. This form is easy to clean up, while it offers many different colors for your option.
If you are using a fiberglass tub, silicone caulk is more recommended. You will have fewer options for the color, and the material isn’t smooth, but it’s very flexible.
Step 4: Prepare
Like painting projects, applying caulk requires proper preparation before getting to work. You also need to tape the areas around the tub to avoid the caulk.
There are going to be two strips of painter’s tape: one is above the edges where you apply the caulk, and one is below those. The gap between these two strips is the place where you will fill the caulk. Well, it’s also the width of the caulk and normally about 0.95 centimeters.
When you finish taping, prepare an application gun that is not too old as the old one may leave uneven patterns of caulk. Cut the top of the caulk tube for 45 degrees, place the stick of the gun through the tube’s nozzle to break the seal, then we are ready to apply the new caulk.
Step 5: Apply the new caulk
Look at the gap between the strips you have just taped, steadily press the trigger of the gun. When you see the caulk going out of the gun, keep it stable while applying the entire edge alongside the bathtub. You should start from the corner and then use alongside the length of the bathtub for a smooth finish.
It’s essential to pull the trigger steadily as it won’t make the caulk too thin or thick. You don’t need to worry if the caulk moves on the tape as you will peel the tape eventually.

Step 6: Finish
The finish is often less considered by most people, but it turns out to be one of the vital steps.
First, you need to smoothen the layer of caulk to create the concave shape. As the new caulk has just been applied, you should use a damp paper or towel to press it gently. Use your little finger, and run it alongside the caulk, starting from the corners.
When the thing is done, peel away the painter’s tape around the bathtub and have a look at a seamless line of caulk. How you apply the tape will decide the line of the caulk.
Finally, keep the tub dry for 48 hours before you can use it. Also, remember to keep your bathroom fresh, clean, and ventilated.

Tips for using
Of course, this project has some tricks and tips to make things easier and more efficient. Let’s see the tips below if you find any difficulties in the caulking bathtub.
Tip 1: Cut the caulk tube with care
The cut you make will decide how much and how well the caulk runs out from the tube. Thus, make sure to deliver a 45-degree, sharp, and cut to the caulk tube. The cut should also be near the end, while you need to smoothen and soften the tip with sandpaper.
Tip 2: Smooth the caulk with your finger
Only the finger can smoothen the caulk after you apply it to the bathtub. Remember to dampen your finger first and use a wet rag to clean up the excess caulk on your finger if it gets more and more.
Tip 3: Keep the stable speed and fit the size of caulk’s line
Steady speed is the key to an excellent application. However, it should also match the size of the caulk line (the gap between two painter’s tape). For a smooth, elegant, and thin line of caulk, you need to move the gun at a rapid speed. On the contrary, keep the low speed if you want to produce a thick layer of caulk.
