Waterborne polyurethane finish has become a popular choice for many applications, from furniture to flooring, due to its environmental friendliness, low odor, and relatively quick drying time. As a supplier of waterborne polyurethane finish, I often get asked whether this type of finish loses its luster over time. In this blog post, I'll dive into the factors that can affect the long - term luster of waterborne polyurethane finish and share some insights on how to maintain it.
What Causes Loss of Luster?
1. Wear and Tear
One of the most common reasons waterborne polyurethane finish might lose its shine is regular wear and tear. When the finish is constantly exposed to foot traffic, abrasion from objects moving across its surface, or even friction from cleaning, the top layer can gradually get worn down. Think about a high - traffic hallway in a commercial building. Every time someone walks on the floor, there's a tiny bit of friction between their shoes and the finish. Over time, these small abrasions can accumulate, dulling the once - shiny surface.
Our High Wear Resistant Polyurethane Finish is designed to combat this issue. It has a high - performance formula that can withstand a significant amount of abrasion, helping to keep the luster intact for a longer period.
2. UV Exposure
Ultraviolet (UV) rays from the sun can also have a detrimental effect on the luster of waterborne polyurethane finish. UV radiation can break down the chemical bonds in the finish, causing it to yellow, crack, and lose its shine. If you have a piece of furniture near a sunny window or an outdoor structure coated with waterborne polyurethane, it's more likely to experience a loss of luster due to UV exposure. To protect against this, some finishes are formulated with UV inhibitors. However, over time, the effectiveness of these inhibitors can wear off, and the finish may start to show signs of degradation.
3. Chemical Exposure
Certain chemicals can react with waterborne polyurethane finish and cause it to lose its luster. For example, harsh cleaning agents, solvents, or even some types of food spills can have an adverse effect. If you use a cleaner that's too abrasive or contains strong chemicals on a surface coated with waterborne polyurethane, it can strip away the protective layer and dull the finish. It's important to use gentle, pH - neutral cleaners specifically recommended for use on polyurethane finishes.
How to Maintain the Luster of Waterborne Polyurethane Finish
1. Regular Cleaning
Regular cleaning is crucial for maintaining the luster of waterborne polyurethane finish. Use a soft, microfiber cloth or a mop to remove dust and dirt from the surface. For light cleaning, a simple solution of mild soap and water can do the trick. Avoid using abrasive sponges or scrubbers, as they can scratch the finish. Make sure to dry the surface thoroughly after cleaning to prevent water spots, which can also make the finish look dull.
2. Protect from UV
If the coated surface is exposed to sunlight, consider using window films or blinds to block out UV rays. For outdoor applications, you can apply a UV - protective topcoat periodically to extend the life of the finish and maintain its luster.
3. Use Protective Mats
In high - traffic areas, such as entryways or kitchens, place protective mats to reduce the amount of abrasion on the finish. Mats can trap dirt and debris from shoes, preventing them from scratching the surface.
Comparing with Other Finishes
It's interesting to compare waterborne polyurethane finish with other types of finishes in terms of long - term luster.
Epoxy Electrostatic Conductive Self Levelling
Epoxy Electrostatic Conductive Self Levelling is another popular finish, especially in industrial settings. Epoxy finishes are known for their high durability and chemical resistance. However, they can be more difficult to apply compared to waterborne polyurethane finishes. In terms of luster, epoxy finishes can also lose their shine over time, especially in high - traffic areas. But with proper maintenance, they can maintain a decent level of gloss. Waterborne polyurethane, on the other hand, offers a more user - friendly application process and generally has a quicker drying time, which can be an advantage for many projects.
Floating Sand Self Leveling
Floating Sand Self Leveling is often used for creating textured or anti - slip surfaces. While it provides a different aesthetic compared to a smooth, shiny waterborne polyurethane finish, it can also lose its appearance over time. The sand particles can wear down, and the overall surface may become less defined. Waterborne polyurethane, with its smooth finish, can offer a more consistent and long - lasting luster when properly maintained.
Conclusion
So, does waterborne polyurethane finish lose its luster over time? The answer is yes, it can, but there are many factors at play. With regular wear and tear, UV exposure, and chemical exposure, the luster can gradually fade. However, by choosing a high - quality product like our High Wear Resistant Polyurethane Finish and following proper maintenance practices, you can significantly extend the life of the finish and keep it looking shiny for years to come.
