Adding an extra layer of protection is an essential part of increasing the lifespan of the material. Lacquers and polyurethanes are the most recommended products by many when it comes to adding a protective layer to the surface because they have been proven to be durable. If you haven’t used them yet, you may be wondering what product will make my material last longer?
To help you decide what kind of coverage you should apply to your project, we will discuss the differences between lacquer and polyurethane in terms of their durability. Not knowing the difference between the two will not only waste your money but also damage your wood decks, automotive parts, textiles and other materials.
Lacquer
Lacquers are often described as the best finish for wood projects because they have the ability to dry quickly and are durable. They contain a shellac-like solution that creates a durable synthetic coating. Drying time Application performance and durability
In applying lacquer, speed is essential as it dries very quickly within about 10 minutes or so of application. You can re-coat the material with lacquer after 30 minutes. Lacquer acts like its own solvent, which means, if you apply a second coat to your material, it will dissolve the first coat and provide a smoother finish.
Polyurethane
Polyurethane provides a smooth finish in the form of a liquefied plastic until it dries on your material. It comes in both oil-based options and water-based variants, but many people prefer the latter because it has a much lower odor and lower toxicity. Drying time Application performance and durability
Polyurethane takes 12 to 24 hours to dry before you can recoat it. Polyurethane also has a pungent odor that can last for several weeks after application.
Overall, which is more durable?
Lacquer is prone to scratches and has low thermal stability. The nitrocellulose chemical in lacquer degrades the object when exposed to repeated heat. If not handled properly and with safety precautions, it can pose medical hazards.
Although lacquer dries quickly, is easy to apply and requires little maintenance, polyurethane is many people’s first choice when it comes to longevity because it is more durable than lacquer. Polyurethane contains additives that make it more resistant to moisture, sun rays and abrasion. It also lasts longer than lacquer without constant maintenance.
Our comparison of lacquer and polyurethane ends here. Polyurethane is more expensive than lacquer but it will save you time and money in the future.
