Depending on the current condition of your bathtub, a re-painting project can take anywhere from two to four hours. If you have never painted a bathtub before, it's best to closely follow the directions given by your paint manufacturer. It's also important to make sure that you are using paint that is suitable for your particular bathtub's surface.

Things you'll need:

  • Rustoleum Tub Refinishing Kit
  • Paint Brush
  • Paint Roller
  • 400 and 600-Grit Sandpaper
  • Lime Cleaner
  • Drop Clothes
  • Plastic Gloves
  • Comet Cleaner
  • Cleaning Sponges
  • Painter’s Tape

1. Prepare the space

Before you work on any painting project, it's always best to lay down a drop cloth to protect your floor and any surrounding furniture. Be sure to tape the drop cloth around the front of the tub, so it does not slip when you kneel on it. It's also a good idea to open up a window in any doors to the bathroom to ventilate it before applying the epoxy, as the fumes can be very strong and may cause light-headedness.

2. Remove old caulk and hardware

tart by taking your putty knife and any old caulk from around the surface of the tub. You may need to remove the drain hardware in any other fixtures at this time.

3. Thoroughly clean the bathtub

Clean the tub with an all-purpose cleaner, and then rinse it off with warm water. It's also a good idea to then wash the tub with a diluted bleach solution. It's best to use a solution that has anywhere from 5% to 10% bleach to thoroughly clean the tub before refinishing it. Be sure to scrape away any grime and hard water stains or other surface discolorations at this time.

4. Repair any surface damage

Next, use this time to fix any damages to the tub surface. Fill any chips, scratches, or cracks with epoxy or a recommended tub repair kit. Make sure that the epoxy dries completely before applying additional coats.

5. Sand down the tub

Next, take the 400-grit sandpaper and sand down the areas where you apply the epoxy. Next, grab your 600 paper and take a second pass over the entire tub. The finer-grit paper will help the paint adhere to the tub's surface better. When sanding down the repaired areas, make sure that they are sanded enough so that they are flush with the rest of the tub--you don't want any bumps in the surface of the tub when you re-paint it.

Find sandpaper on Amazon.

6. Apply painter's tape

Now's the time to apply your painter's tape to the areas around the edge of the tub and any over hardware that you don't want to paint. To avoid getting paint on the wall by sure to use the edge of your putty knife to push the painter's tape into the corner between the edge of the tub and the wall to prevent accidental brushes.

7. Dry the bathtub

Take a large dry towel and dry off the surface of the tub, as it needs to be completely free of moisture before applying the paint. Be careful not to peel off the painter's tape on this process. You may want to wait about 10 minutes to ensure that the tub is completely dry. Once it is, prepare your epoxy (or primer) if it needs to be mixed or apply it to the tub at this time.

8. Apply Primer

Take your 4-inch paintbrush and lightly dip it in the primer to apply it to the tub. Be sure not to apply the paint primer too heavily, as it will clump up and begin to bubble as it dries. You should use light brush strokes and apply one or two additional coats after the previous coat has dried.
