Buying Guide
- Finish Type: Choose satin, semi-gloss, or gloss based on your project’s aesthetic and durability needs. Satin hides minor scratches better; gloss highlights grain and detail.

- Dry Time and Recoat: Look for products with fast dry times and practical recoat windows to maximize productivity. Note that outdoor spar urethanes may require additional cure time in harsh conditions.
- VOC and Odor: Water-based finishes generally have lower odor and VOC levels, but ventilation is still important during application.
- Finish Stability: Some products are archival or UV-protective, which can be crucial for art preservation or outdoor exposure.
- Surface Compatibility: Confirm compatibility with stains, paints, and underlying coatings to avoid incompatibility issues.
