1. Inadequate Surface Preparation
One of the most critical steps in bathtub refinishing is surface preparation. This means ensuring that the old bathtub has been processed in a way that supports strong adhesion of the new coating. Otherwise, you may experience premature peels or chips that necessitate additional refinishing.
Luckily, you can avoid this mistake by thoroughly cleaning the tub, removing old coatings, and sanding and etching the surface. Remove all dirt, soap scum, and oils from the bathtub surface using a strong degreaser or cleaner. Then, if the bathtub has been refinished before, the old coating needs to be stripped away. Finally, lightly sanding and etching the surface creates a texture that helps the new coating adhere better. However, any residue from the etching must be thoroughly removed before proceeding.
2. Ignoring Moisture and Temperature Conditions
Environmental factors, such as humidity and temperature, play a significant role in the success of a refinishing job. This means that any moisture on the surface or in the air can prevent the coating from curing properly.
Before refinishing, the bathtub needs to be 100% dry. You may also want to control humidity levels, as it can interfere with curing. An experienced bathtub refinisher will know precisely how to handle any fluctuations in moisture or temperature so you can rest easy.
3. Using Low-Quality or Inappropriate Materials
Not all coatings and materials are suitable for bathtub refinishing. In fact, using the wrong type of paint or refinishing product can lead to a poor finish that doesn’t last. If you partner with a reputable company, this is an easily avoidable mistake, but be careful if you try to DIY. Products must be designed explicitly for bathtub refinishing, as they are formulated to withstand moisture, heat, and regular cleaning. Some stripping agents may also contain hazardous chemicals, which can pose serious health risks. It’s best to stick to high-quality options.
4. Skipping the Primer or Adhesion Promoter
A primer or adhesion promoter is essential for ensuring the new coating securely bonds to the bathtub surface. Skipping this step can lead to premature peeling or chipping. A bonding agent will help enhance durability and longevity, but it requires special care. Even if DIY bathtub refinishing sounds easy, working with a professional can help ensure the best results.
5. Rushing the Curing Process
Curing time is crucial to the durability of the refinished bathtub. Many people make the mistake of using the tub too soon, leading to smudges, dents, or weakened coatings. While bathtub refinishing takes much less time than a full-blown replacement, you still need to wait about 24 hours for it to cure properly.
6. Neglecting Safety Precautions
Refinishing a bathtub involves working with chemicals and coatings that can be harmful if inhaled or if they come into contact with the skin. Always use gloves, safety goggles, and a respirator mask to protect yourself from chemical exposure. It’s also important to use exhaust fans, or set up additional ventilation systems to disperse toxic fumes.
7. Attempting Complex Repairs Without Experience
While DIYers can tackle minor bathtub projects, many require professional expertise. Deep cracks, structural damage, or extensive wear may be beyond the scope of a simple refinishing job. To avoid causing more harm than good, partner with a professional team like Surface Doctors.
