What are the differences between polyurethane and varnish when it comes to protecting a table top?
Polyurethane and varnish are both protective coatings for table tops, but they have some key differences. Polyurethane is a synthetic material that forms a durable, clear finish when applied to wood. It is resistant to water, chemicals, and scratches, making it a good choice for high-traffic areas. Varnish, on the other hand, is a traditional finish made from resins, oils, and solvents. It provides a glossy or matte finish and is often used for decorative purposes. Varnish may require more maintenance and can be more prone to yellowing over time compared to polyurethane.
