Selecting the ideal exterior polyurethane for your project can depend on a variety of factors, including weather conditions. In areas with higher humidity or heavier precipitation, opting for stronger and longer-lasting options may be best to ensure that it retains its quality throughout seasonal changes. Alternatively, if you’re in an environment with less moisture and milder temperatures year-round, more environmentally friendly alternatives are also available. Understanding which type will work most optimally helps make sure your surface looks great every season.
Drying Time
When selecting an exterior polyurethane, the drying time is a crucial component to take into account. Since some products may require more time than others to dry, you must plan your project accordingly and allow for each layer of finish to set up before adding new coats. Keep this in mind when making your selection and allocate sufficient room on your timeline so that you can accurately complete the job at hand.
Sheen Level
When selecting an exterior polyurethane, you must also factor in the gloss level. From brilliant shine to a more muted feel, various levels of glossiness are available – from high-gloss and matte finishes. To add luster and protection to your wood surfaces, opt for a higher sheen result, whereas if you desire something subtler with a natural look, then go for the matte finish option. So before making your choice, consider what aesthetical outcome is desired as this will help you decide which type of finish will be optimal.
Durability
When selecting the right exterior polyurethane, you must consider its durability. A dependable product is capable of enduring wear and tear, discoloration, and cracking; thereby providing long-lasting protection to the surface, it covers.
