For example, the lack of proper and in-depth cleaning can result in a poor bathing or soaking experience, and also improper paint can cause the bathtub surface to degrade over time and render the whole bathtub useless. 

7 Steps to Perform a Bathtub Reglazing

STEP #1 First thing to do when performing a bathtub reglazing is to thoroughly clean the bathtub. You can use an all-green cleaning agent and homemade solution (hot water and vinegar in a 1:2 ratio). Along with cleaning the bathtub, you can also remove the old caulking and reapply the new one. Also do not forget to clean the bathtub’s surrounding area.

STEP #2 Make sure that the working area is clean and well-ventilated. This helps to remove all the gases (during the painting process). Ensure you are wearing proper gear to carry out the project safely including gloves and a mask. 

STEP #3 Now is the time to remove any dirt and debris from the drain and fixtures. You can use hot water to clean the drain line and ensure there are no harmful chemicals in the drain. You can also use a plunger to remove any dirt in the drain and in the surrounding area.

STEP #4 Now that the bathtub is clean, make sure the surface of the bathtub is prepared for the reglazing process. You can use a blunt razor (at least not a very sharp one) and chip away the already chipped surface. Be sure to cover all the surfaces. Once you are done with that, it is time to sand it. Take a sandpaper with 40 to 80 grit and sand the surface carefully. Now, this will take you around 15-25 minutes depending on the condition of the bathtub. You might think that sanding the surface of the bathtub especially porcelain or even enamel-coated surface may destroy it. That is not the case. You can use the mentioned grit sandpaper to sand the surface without any issues. The only material that you need to take care of is, acrylic or fiberglass material, but that too, you can sand with proper steps to ensure there is no damage to the surface.

STEP #5 Now, the bathtub is fully sanded, it is time to fill the damaged area to smooth out the entire surface. You can find the filler (based on your bathtub’s material) in your local hardware store or even online. Follow the instructions provided by the manufacturer on how to apply the filler with the correct amount. Let the filler dry for some time (the time will vary depending on the type of filler and bathtub material).

STEP #6 Clean the bathtub surface with a soft cloth. Once you cleaned the surface, the next step is to tape the drain and do the caulking. This helps to separate the sensitive spots (such as drains and caulking) from the paint. Then it is time to apply primer.  It is recommended to go with an Epoxy resin primer. The main reasons are, it is Suitable for most bathtub materials and takes only a few minutes to dry (usually 5-10 minutes). Spray the first coat of primer and ensure you cover the entire surface. Let the primer sit on the surface for a few minutes (5-10) and repeat the process the required number of times. Usually, 2-3 primer coatings are enough. To be on the safer side, it is better to go with 3 coatings of primer. 

STEP #7 For the final coating (either second or third coating), you can use the roller to apply the primer on the surface and brush for a “not-easily” reachable surface. This way you will be assured to cover all the surfaces and apply evenly. Let it dry for 10 minutes. Now, the last step is to provide the refinishing coating (paint for your bathtub). Same to the finishing primer coating, you can use a roller to apply your desired colored paint on the surface of the bathtub and use a small brush to apply the paint where the roller is not possible. You can apply two coatings of paint and let it dry for at least 24 hrs, but it is recommended to leave it to dry for 48 hrs and ensure there is no moisture or water near the bathtub. After 48 hrs, the bathtub is ready!
