These substances are used for different applications and have different strengths and weaknesses, but they still serve the same purpose ultimately. The two variations of polyurethane coatings are oil-based polyurethane and oil-based polyurethane respectively. To most of us, polyurethane is just a coating that can be used to seal and protect our workpieces, but there are subtle differences in the two types of polyurethane that are available for both private and commercial use. We’re all human at the end of the day (we hope), and after a long day of painting and/or sealing a workpiece, it can seem like the most herculean of tasks to clean our tools, even though it’s for our own benefit.Īre There Different Types of Polyurethane? This might sound simple it can be quite the internal battle. What this all boils down to is that it is best to condition yourself to clean your brushes as soon as you’re done using them. The level of difficulty you’ll encounter also depends on which type of polyurethane coating you choose to use on your workpiece, using a water-based polyurethane coating will be significantly easier as simply dipping your brush in water will dissolve the polyurethane base, but using an oil-based polyurethane coating may result in increased difficulty in the removal process. But, if you can make a habit of removing the polyurethane from the bristles as soon as you are done applying your coating you will still have your trusty brush, none of the frustration, and save yourself a fortune in the long run.

This is arguably one of the most versatile materials on the face of the planet, being used in seemingly every industry in existence, polyurethane is considered by many to be a sort of miracle material compared to others that came before it.Īlthough it is versatile, effective, and long-lasting, polyurethane coatings can be challenging to clean up.
