If that’s the case of yours, or the bathtub is placed within a plaster, or wooden housing, use of a painter tape to cover up the tub’s edges. This is to help prevent the new finish from reaching anything other than the bathtub.

If you’re using a freestanding tub, you can neglect this step above. However, you will need to cover every other thing in the bathroom with plastic except for the tub itself. These include covering the sprout, handles, shower head, bath nozzle, and bathtub chair any other things.

After you have finished covering the necessary things, you can use a painter tape to make the plastic stay secured in place. Also, since the wall isn’t a part of the bathtub, you should ensure to cover it up too. You can cover the wall using plastic with the aid of painters tape or masking paper.

For those that will be using the spray-on finish, hold the can at a close distance to the tub. Then spray the finish from left to right repeatedly without backtracking to produce overlapping coats. If yours is the mixed type, roll it in a single direction repeatedly to achieve the same result.

Keep in mind that when applying this coat, you have to ensure it covers of the tub surface very well. Also, avoid touching the finish after you apply it over the tub because this can create permanent marks.

Step 9. Leave It for Few Minute to Dry After Each Coating

Before applying an extra coating of the finish or glaze to the tub surface, it’s best to leave it for at least 10-15minute to cure. During humid days or If your bathroom isn’t well ventilated, you may have to wait extra more minutes. The reason is that allowing the coat to cure before applying the next helps them seal properly.

Once the tub is completely dry, take off all the tape, paper, and plaster you used to protect the hardware and walls.

But before you remove them, it is best to read the instruction on the bathtub finish you used to know how long it needs to cure before reusing the tub. This process is to prevent you from messing up the finish when removing the tape because some part might not have dried well.

After you’re have uncovered completely, apply the caulk along with all the places you removed the caulk before. You should avoid using silicon when recaulking because it does not seal well with bathtub finishes. Instead, use a non-silicone caulk with anti-mildew properties.

It’s best to use a squeeze tube to apply the caulk. After you have applied the caulk, put on a latex glove and press the caulk into the crack to create a smooth finish. Ensure to hold your hands flat on the tub to smooth the caulk.

Give the caulk enough time to dry well before you use the bathtub. Read the instruction the caulk you purchased to know how long it needs to dry before you use the tub again.
