Now that we have described the main differences in the comparison table, let’s go on to elaborate those points in brief detail.
Tone/Color
This is one of the most important factors that you should consider while purchasing polyurethane for your floor. The color of oil-based polyurethane is an amber hue which is a very rich and attractive color and darkens over time. In contrast, water-based polyurethane is clear. That means you can behold the actual beauty and color of the wood in water-based polyurethane.
Number of Coats
Always remember that oil-based polyurethane is thicker while water-based polyurethane has a thin layer. While using oil-based polyurethane, most of the time you can get away with only 2 coats of poly because of it thicker build up. In comparison, water-based polyurethane requires more than 2 coats to get the proper build up to achieve the desired durability.
Texture
The texture is usually very important for customers. Practically, if you go for a water-based product, you experience a slightly rougher texture. That is due to the fact that water-based poly lacks the oil lubricant that oil-based polies contain. On the other hand, the oil-based product has a smooth texture.
Drying Time
Another important factor is the drying time. Oil-based polyurethane takes a lot more time to dry up compared to water-based.For example, one coat can take up to 24 hours to dry. In comparison, the water-based product dries very fast, usually within 4 to 6 hours, allowing for multiple coats in one day.
Odor
When you are working with polyurethane, you have to keep in mind the odor. If you go for water-based polyurethane, it offers an insignificant odor and is safe for people to occupy a house while undergoing the application. When you go for the oil-based polyurethane, you face a pretty harsh odor and dangerous fumes that should not be inhaled. That is due to the high VOC levels it contains, therefore you should wear a respirator when applying oil-based polyurethane. As a result, people should not occupy the house while oil-based poly is applied and drying.
Cost Analysis
When you decide to buy something, you always have to make compromises. Either you compromise a feature for the price, or you buy the expensive product for the great features it provides. Water-based polyurethane is unique when it comes to its insignificant, non-irritant odor and fast drying time. However, such great features come at a cost. The price of water-based polyurethane is more expensive in comparison to oil-based poly.
Change over Time
Changes in the finish become apparent over time. Oil-based polyurethane darkens over time giving the floor an amber hue. Water-based polyurethane remains clear overtime keeping the natural look of the wood which is highly sought after when you don’t want to alter the color.
