- Wax, on the other hand, is a natural substance that creates a soft, malleable layer. It offers a more subtle sheen and a smooth feel when touched.
Because of their different compositions, polyurethane and wax may not adhere well to each other. This can result in poor adhesion and potential issues with the finish, such as peeling or bubbling.
Adhesion Issues
When applying polyurethane over wax, adhesion issues can arise due to the incompatible nature of the two substances. Polyurethane typically adheres best to surfaces that are clean, dry, and free of any contaminants, such as wax.
As a result, the wax layer may need to be removed or properly prepared to ensure good adhesion. This could involve sanding the wax surface to create a rougher texture or using a suitable wax remover to eliminate any residue.
Additionally, it’s important to consider the age and condition of the wax layer. Over time, wax can become worn or damaged, making it less suitable as a base for polyurethane. In such cases, complete removal of the wax may be necessary before applying polyurethane for optimal results.
By understanding the different chemical properties and potential adhesion issues, you can navigate the challenges of applying polyurethane over wax. Taking the necessary steps to ensure proper surface preparation will help you achieve a beautiful and long-lasting finish.
