- Read reviews from other customers to get a sense of the product’s performance and ease of use.
What is the Best Polyurethane for Exterior Wood Furniture?
Exterior wood furniture requires a high-quality polyurethane finish to withstand the elements and maintain its beauty. With so many options available, choosing the best polyurethane for your project can be overwhelming.
Here are some key factors to consider when selecting a polyurethane:
- Durability: Look for a polyurethane with high scratch and wear resistance.
- UV resistance: Exterior wood furniture is exposed to direct sunlight, which can cause fading and discoloration. A polyurethane with high UV resistance will help prevent this.
- Water resistance: Wood furniture near water sources or in humid environments requires a polyurethane with good water resistance.
- Finish: Consider the finish you want to achieve: matte, satin, or gloss.
Based on these factors, some of the best polyurethane options for exterior wood furniture are:
- General Finishes High-Performance Polyurethane : Offers excellent durability and scratch resistance, making it a great choice for high-traffic areas.

Can I Use a Spar Varnish as a Alternative to Polyurethane for Outdoor Furniture?
When it comes to protecting and enhancing the look of your outdoor furniture, choosing the right finish is crucial. Two popular options are spar varnish and polyurethane. But can you substitute one with the other? Let’s break it down.
Spar varnish is a marine-grade varnish designed for use on exterior wood surfaces, including boat decks, railings, and… outdoor furniture. It’s known for providing a durable, water-resistant finish that can withstand sun, rain, and salt air. Spar varnish is also relatively easy to apply and maintain.
Polyurethane, on the other hand, is a clear coating commonly used to protect and enhance wood surfaces indoors. While it can be used outdoors, it’s not specifically designed for marine or high-UV exposure environments.
- Pros of using spar varnish:
- Better water resistance
- More durable finish
- Suitable for high-UV exposure areas
- Cons of using polyurethane:
- May not be as effective in marine or high-UV environments
- Can become brittle and prone to cracking over time
If you’re looking for a water-resistant, durable finish for your outdoor furniture, spar varnish might be the better choice. However, if you’re working with a smaller, indoor project, polyurethane could be a suitable option.
Is Epoxy a Better Option than Polyurethane for Outdoor Furniture?
When it comes to protecting your outdoor furniture from the elements, there are several options to consider. Two popular choices are epoxy and polyurethane. But which one is better?
What Are the Differences?
Epoxy and polyurethane are both coatings used to protect and preserve the surface of outdoor furniture. However, they have some key differences.
| Property | Epoxy | Polyurethane | | — | — | — | | Flexibility | Less flexible | More flexible | | Adhesion | Better adhesion to surfaces | Can be prone to peeling | | Gloss | High-gloss finish | Matte to high-gloss finish | | Durability | More resistant to scratches and fading | Resistance varies depending on type | | Cost | Generally more expensive | Generally less expensive |
Which One is Better?
Ultimately, the choice between epoxy and polyurethane for outdoor furniture depends on your specific needs and preferences. If you’re looking for a high-gloss finish and top-notch durability, epoxy might be the better option. However, if you’re on a budget and prioritize flexibility and a matte finish, polyurethane could be the way to go.
Considerations
Before making a final decision, consider the following:
- The type of outdoor furniture you have: Epoxy works well on surfaces like wood and metal, while polyurethane is better suited for plastic and fabric materials.
- The level of maintenance you’re willing to commit to: Epoxy requires more maintenance to keep its high-gloss finish, while polyurethane is generally easier to clean and maintain.
- Your desired level of protection: If you live in an area with severe weather conditions or heavy use, epoxy’s added durability might be worth the extra cost.
Both epoxy and polyurethane have their strengths and weaknesses. By considering your specific needs and preferences, you can make an informed decision about which coating to use on your outdoor furniture.
