We can categorically say that this is a matter of choice, but to fully understand what your options are, we will take a quick dive into the similarities, differences, pros, and cons of both water-based and oil-based polyurethane.
Both water-based and oil-based polyurethane offers similar advantages, the major difference between the both of them is in appearance. Since polyurethane itself is the most durable .product when it comes to hardwood floor finishes, the question is usually, which of the two types is harder? Experts in this field have stressed that hardness isn’t exactly a favorable characteristic for choosing a wood finish. If you are using the finish on a door, you may not have any problems but if you desire to use it on your floor you should opt for a finish that can flex with the floor, rather than being rigid. An excessively hard finish will easily show scratches. Once you have applied the finishes, a good way to ensure that your floor lasts is to vacuum or sweep regularly and endeavor to use rugs in spaces that have very high traffic.
Let’s take a look at a few pros and cons of water-based and oil-based polyurethane.
Oil-based Polyurethane Pros
