Things To Consider Before Using Epoxy On Your Tub

First things first! You need to understand few things before you can apply epoxy to a tub. Without adapting to the important factors, you cannot ensure the longevity of the outcome. Here are the things you need to keep in mind:

  1. It would help if you considered the difficulty you might face while using the epoxy over a bathtub. As it is a home improvement concern, you do not want to get things wrong.

  3. Verify the end result with the outcome that you expected right from the beginning. Also, you need to let the epoxy settle down before you can inspect its outcome. 

Steps To Adopt Before Proceeding With The Application Job

Here are the steps that you must adapt in order to prepare the bathtub for epoxy application. 

Step 1: Remove the Old Caulk And Other Hardware 

In the first step, you need to remove the old caulk from your tub. If you do not have the right tool, you can use a knife or a painter’s tool as an alternative. Once you are over with that, you need to remove the hardware that connects to your tub drain.

Along with that, you should also remove any such fixtures from your bathtub that you think might cause a problem while applying the epoxy.

Step 2: Ventilate The Bathroom And Clean The Bathtub

Before you proceed with the application of epoxy, you need to clean the bathtub and ventilate the bathroom. You can use bleach, acetone, and scrub cleaner, depending upon the material of your bathtub, for cleaning it efficiently.

For ventilation, you can simply ensure sufficient airflow within your bathroom space. And for that, you can open up the windows or keep the bathroom exhaust fans on. 

The bathtubs often accumulate soap scum, mildew, and grime, over an extended usage period. Therefore, for cleaning it, you must use around 10% of bleach solution in water. Use it to remove the first layers of visible dust, grimes, and accumulations from the tub.

Now, you can make use of the bathroom cleaner to achieve further efficiency in cleaning. Make sure you wipe out the cleaning solutions properly, without which they will give an uneven texture to epoxy coating. Also, you can use a paint thinner or acetone solution for the remaining leftover cleanser or grease remnants. 

Step 3: Fix The Damages Or Wears In Your Bathtub

In case there are any chips, gouges, or scratches over the bathtub, you need to fix them before you can proceed with painting the bathtub with epoxy. You can use tub repair products to fill those cracks or scratches for getting a new-like surface.

Let them dry, after which you can sand out the excessive parts to make the surface smooth. You can use either wet or dry sandpaper. A 400-grit sandpaper and 600-grit sandpaper will do the work. 


Make sure you rinse the bathtub properly and wipe it with a clean cloth to get it dry. Use clean rags and towels for the purpose. Also, there shouldn’t be any moisture while you apply the appliance epoxy paint. Mask out all the surrounding tile surfaces and other fixtures to avoid accidental painting. 

Step 4: Get Started With The Paint Job

  1. Get two foam rollers and brushes, along with a vapor mask. 
  2. Along with that, get a roller tray as well. 
  3. Buy the appliance epoxy, or use the leftover ones that you used for painting your refrigerator. 
  4. In case you have two-part epoxy, then you need to mix. Combine them well for prior application. 
  5. Use the roller and apply an even first coat. 
  6. Smooth out all the dips and lumps with the use of a brush or roller. The bubbles will set automatically once the epoxy settles down. 
  7. Let the first coat dry out, and then you can apply the second layer onto it. 
  8. Let the bathtub dry with the appliance epoxy paint for at least three days before you can run water over it.
