A carpenter builds a wooden table. He wants the table to shine and last long. He thinks about two finishes: polyurethane and lacquer. Both protect wood. Both make the surface smooth. But there is a clear difference between polyurethane and lacquer.
The difference between polyurethane and lacquer is about durability, drying time, and application. Many DIY beginners feel confused about the difference between polyurethane and lacquer when choosing a finish.
When we understand the difference between polyurethane and lacquer, we can choose the right finish for furniture and floors.
Pronunciation
- Polyurethane
