Problems with refinishing a bathtub 

The process of refinishing a bathtub can be problematic if you are not careful with the surface preparation. Improper surface preparation can result in bubbles and cracks in the finished coating. Proper surface preparation prevents these problems. Poor surface preparation also makes it easier for air to get trapped between the layers of the coating.  

Another problem with refinishing a bathtub is the risk of the underlying layer of the tub breaking or peeling off. Fortunately, this problem isn’t as common as you might think. Refinishing a tub can be an easy and cost-effective fix for a damaged tub, but it is a delicate process that should be left to a professional. 

Methods of refinishing a bathtub 

One of the most common problems associated with bathtubs is bubbles, which are caused by air trapped between layers of the coating. This can occur if the coating is not properly cured or if the refinisher did not strip off the old finish thoroughly. It is important to remove the old finish in order for the new one to properly bond to the substrate. Failure to do so may result in bubbles in the finished product and may also cause premature failure of the new coating.  

The first step in the bathtub refinishing process is sanding the surface. A smooth surface is the best surface for the new finish to adhere to. Depending on the type of finish you’re choosing, you may need to spend some extra time repairing chips and cracks.  

Causes of refinishing job bubbles 

Bubbles on the surface of your bathtub can be a result of poor surface preparation and improper coating application. Poor surface preparation can cause air to be trapped between layers of coating. The finish also may not cure properly, resulting in the formation of bubbles. Proper surface preparation is essential to prevent these problems and ensure the long-term durability of the new coating. Proper surface preparation also prevents cracking, which is caused by over-catalyzing the coating.  

Another common cause of bubbles on bathtub refinishing jobs is the improper application of epoxy. If the coating is applied incorrectly, the surface will have brush or roll marks. Failing to allow the tub to dry between coats will mar the final layer. If the surface feels tacky, it may be time for a full stripping and refinishing. 

Safety precautions for tub refinishing 

When performing bathtub refinishing, it’s important to follow certain safety precautions. First, ensure that the area is well-ventilated, especially around the tub. This will help prevent the buildup of toxic vapors. Second, ensure that you’re wearing proper protective equipment. This includes using a HEPA air filter and coveralls. Third, be sure that the area is free of dust and debris to prevent the spread of contaminants.  

Before refinishing, you must clean the bathtub thoroughly. You can use a chemical bathroom cleaner to remove built-up dirt and soap scum from the surface. You should also remove any caulking and hardware. After removing all of these, you should use an abrasive pad to remove the remaining caulk.
