What is Polyurethane Used For

What is Polyurethane Used For?

Polyurethane is a popular and durable finish used to protect wood and wooden objects from sustaining further damage or wear over time. It is a water-based resin that dries quickly and resists staining, cracking, and yellowing of the finish over time. It has a high gloss, satin finish, or matte finish and can be used on both interior and exterior projects.

Polyurethane is used for:

• Protecting hardwood floors
• Sealing and protecting wooden furniture
• Sealing and protecting decks
• Sealing and protecting cabinets
• Sealing and protecting wooden trim pieces
• Finishing unfinished wood projects
• Preserving woodturning projects

Polyurethane can also be tinted to create beautiful, rich colors and it bonds well with other finishes, such as lacquer and varnish. It is one of the most versatile and durable finishes available, making it one of the most popular choices among professionals and homeowners alike.

What is Epoxy Used For

Polyurethane and epoxy are two popular wood finishes that offer different sets of characteristics and advantages. Epoxy is commonly used as a wood finish due to its ability to protect wood from water damage and increase the durability of the wood. It is also the most attractive wood finish in most cases. On the other hand, polyurethane is a more affordable and easier to use option for wood finishing.
